The CPG is a system where Federal agencies (also State and local agencies, and contractors working with Federal funds) must preferentially purchase products containing the highest percentage of recovered materials practicable. Procuring agencies are defined as: 1) any Federal agency; 2) any state or local agencies using appropriated federal funds for a procurement; or 3) any contractors with these agencies (with respect to work performed under the contract). This would include composts made from biosolids, manures, food waste and from yard wastes. Under the USDA program, Federal agencies and contractors are required to purchase USDA-designated biobased items unless they determine that products are not reasonably available, fail to meet performance standards, or are available at an unreasonable price. A biobased material is an organic material in which carbon is derived from a renewable resource via biological processes. The one biobased item on the USDA list that pertains to compost is "fertilizers" which must have a minimum 71% biobased content. USDA defines "fertilizers" as "products formulated or processed to provide nutrients for plant growth and/or beneficial bacteria to convert nutrients into plant usable forms. Biobased fertilizers, which are likely to consist mostly of biobased components, may include both biobased and chemical components." Thanks much for any leads you could offer on this.

There is no such term as anaerobic composting, The term to use is anaerobic digestion. During composting the predominant gas produced is CO2 whereas under anaserobic digesion it is methane. Methane is 21 time stronge as CO2. Furthermore the addition of compost to the soil sequesters carbon. During anaerobic digestion the methane should be captured. Furthermore the solids residues which may contain higer concentration of undesired material must be composted or land applied.

Nonetheless, here are some data on this and then some discussions that parallel the topic. It will be of interest to note that these materials may not break down totally. Thus the question remains, how effective is compost in these matters? In addition, there are robust genetic fragments of resistant pathogens that must be considered. Of further interest would be the added bulking materials such as sewage sludge and the impact from these materials on the final product. Thus unless one ran a series of tests and had a very consistent source of raw stock, the answer would be confounded by variations in source material. As noted below from Chitnis, if one were to use sewage sludge from a sewer plant with an up-stream large hospital, the loading of antibiotics and antibiotic resistant bacteria could be considerably different from that received from a smaller municipal source. Thus one may also suppose that the loading would also vary amongst various types of meat animal products, their source, and handling and process train used. All this adds up to a need to test frequently and that testing in it self is an area with many issues. STABILITY OF ANTIBIOTICS IN MEAT DURING A SIMULATED HIGH TEMPERATURE DESTRUCTION PROCESS H.J. van Egmond, et al State Institute for Quality Control of Agricultural Products (RIKILT), Bornsesteeg 45, NL- 6708 PD Wageningen, The Netherlands Abstract With a simulation model at laboratory-scale, the stability of sixteen antibiotics during the destruction process of animal and offal's was investigated. The antibiotics were added to a mixture of pork-meat, pork-kidney, and pork-liver (90/5/5) (w/w/w), subsequently pasteurised at 80?C (15 min.), sterilised at 134?C (3 bar, 20 min.) and dried at 100?C (4 hours). During the different stages of this process, samples were taken and analysed for antimicrobial activity by bioassay. The remaining activity after the full destruction process was for lincomycin 80%, flumequine 69%, enrofloxacin 68%, neomycin 46%, tylosin 44%, sulfamethazine 38% and spiramycin 15%. Penicillin, amoxicillin, ampicillin, cloxacillin, oxytetracycline, doxycycline, colistin, dihydro-streptomycin and sulfamethoxazole were fully degraded (less than 10% remaining activity) after the sterilisation step (134?C). It is concluded that the high temperature destruction process does not guarantee a full break-down of residues of veterinary drugs present in condemned animals. Hospital effluent: A source of multiple drug-resistant bacteria V. Chitnis, D. Chitnis* ,? , S. Patil** and Ravi Kant* *Department of Pathology, Choithram Hospital and Research Centre, Manik Bagh Road, Indore 452 001, India **School of Life Sciences, Devi Ahiyla University, Indore 452 001, India The present work was carried out to study the spread of multiple drug-resistant (MDR) bacteria from hospi- tal effluent to the municipal sewage system. The MDR bacteria population in hospital effluents ranged from 0.58 to 40% for ten hospitals studied while it was less than 0.00002 to 0.025% for 11 sewage samples from the residential areas. Further, the MDR bacteria carried simultaneous resistance for most of the com- monly used antibiotics and obviously the spread of such MDR bacteria to the community is a matter of grave concern. DEVELOPMENTof drug resistance has followed the discovery of antimicrobial agents like a faithful shadow. Drug resistance observed till 1954 was through solitary events of bacterial chromosomal gene mutations. However, this is not the case today where the majority is through lateral gene transfer, much of that happening within sewage treatment plants Title: > Composting > rapidly reduces levels of extractable oxytetracycline in manure from > therapeutically treated beef calves > Author(s): Arikan OA, Sikora LJ, Mulbry W, et al. > Source: BIORESOURCE TECHNOLOGY Volume: 98 Issue: 1 Pages: > 169-176 Published: JAN 2007 > > Abstract: Oxytetracychne (OTC) is a broad-spectrum antibiotic used in > livestock production.

It is not correct to say "anaerobic composting". As Eliot Epstein noted, composting is by definition an aerobic thermophilic process. Not mesophilic like anaerobic digestion at 35C. But 55C or above to kill pathogens and obtain aerobic stabilization. Anaerobic digestion is a useful process to generate methane and reduce mass of an unstable biomass. But it does not attain the stability of aerobic processing. Recent trials of thermophilic anaerobic digestion (to obtain pathogen kill and stabilization) produced putrid end products which were not ready to go to land. But thermophilic aerobic digestion gave a low odor product from input sewage solids. Just no energy recovery historically used to power pumps at POTWs. And their product is not ready for commercial application; rather normal controlled land application of the wet or dewatered product. Composting yields a semi-dry friable product ready to mix in soils for many uses. If you still think it appropriate to use "anaerobic composting", please read some of the classic texts and official documents on composting and present some rationale to justify the use. Don't just say that some particular group use it for the commercial benefit of using the "composting" name. That is simply cheating as sometimes occurs with commercial interests. Consider the STA seal of approval. It requires a showing that the material actually composted at 55C or above to obtain the benefits of composting, not some arbitrary claim of the submitter.

This does not mean that the entire pile or windrow is anaerobic. According to data by USEPA and others under those conditions the small amount of methane that could be generated is oxidized befor going into the atmosphere. I believe that pile oxygen leves should exceed 10%. Obviously if temperatures are excessive addition air is needed and consequently oxygen levels will be higher.

In our system a 200 foot long tube is filled with mixed material to be composted. Both ends of the tube are sealed and approximately (12) 2" diameter vents installed near the top of the tube as it lays on the ground. In the process of filling (2) 4": perforated tubes are imbedded near the bottom of the bag for the length of the tube, coupled at one end and connected to a Y at the other end. The third leg of the Y is brought outside the tube and attached to a blower. The blower operates on a timed basis to bring fresh air into the tube, venting to the outside through the 2" vents installed near the top of the tube. The blower forces approximately 400 CFM per minute into the tube at about 2" of static pressure. Usually the blower is set to 10 minutes on and 10 minutes off after the bag is filled. The time may be adjusted as needed based on the measured temperature in the composting material. Usually the temperature will show a steep rise over the first 48-72 hours from ambient to 150 to 160F. Usually the blower on time would be reduced to lower the temperature to 130-140F to prevent drying the material excessively and stopping the composting process. Blower operation will continue for the next 4 to 8 weeks. The temperature will generally stay at 140F for 7-10 days and gradually taper down. When the temperature reduces to 100-110F the material is removed from the bag and windrowed or piled for curing. It would be normal for the material to reheat to 130F once and possible twice after turning in the curing piles, at which time the compost is usually ready for use. When the bag is opened the moisture will have migrated toward the outer perimeter and the center of the matrix will be thoroughly composted but relatively dry. There will be some condensation of moisture on the plastic tube itself. Depending on ambient conditions it may be desirable to add water when curing. The assumptions are that the material going into the Ecopod will have a good C:N ratio, enough bulking materials to allow airflow through the matrix and a moisture level of 50-65 percent. Casual calculations show the blower gives a complete air change about every 80 minutes based on 50 per cent run times. The material quickly composts near the vents forming small biofilters at each vent controlling odor, odiferous volatiles condense on the inside of the tube and are contained in the matrix until they can be completely composted and the matrix is not exposed to ambient precipitation or objectionable vectors. While the Ecopod process does not lineup well with Mr. Crocker's ventilation requirements, given a proper mix and moisture level it works well and successfully produces high quality compost.

Argument: Over 50% of MSW landfilled is of biogenetic origin which makes it a renewable resource. Considering landfill gas (as well as bio gas from digesting MSW) is already registered renewable energy sources WTE has to be as well otherwise I-937 contradictory within itself.

Depending on the type of WTE process utilized - for example the mass burn process only requires minimal amounts of start up fuel (biodiesel or natural gas) ? otherwise self supportive (producing electric and/or thermal power). 2. The composting process uses energy used to turn the compost, to pump in and out water, for aeration, for the watering, heating in winter (as otherwise the biological process does not function correctly) 3. Depending on the type of WTE process utilized ? for example the mass burn process (1000 tons/day) produces enough energy to power 30,000 homes with electricity (more when steam is utilized). 4. Commonly no energy is produced as requirements in the US and individual states do not require energy recovery ? could be (suggestion to locate composting facility adjunct WTE facility as state of the art fluegas treatment can handle additional methane rich emissions from compost. Other emission as laughing gas N2O2 (produced by composting facilities) can also be treated and removed from the environment. It should be noted that composting facilities only produce relatively small quantities of this gas ? however compared to CH4 (Methane) which is 21 times as potent as CO2, N2O2 is 200 times as potent as CO2 or 10 times more potent than Ch4 and a very potent greenhouse gas. It should be removed. That is the reason that in Europe (particular in Germany) composting facilities larger than 10,000 tons/y have to be in enclosed facilities with fluegas treatment (making the process even more expensive). 5. In the US, as in Europe emissions from WTE facilities are very closely monitored. Even though in the 1970s and 80s toxic emissions where considerable, today WTE facilities when compared to landfills or other industries only mostly negligible amounts. The German limits are so stringent that even the German Green Party now accepts WTE as a viable method to reduce the GHGs from waste and for overall environmental protection and economical performance (still focusing on waste reduction and recycling as primary goals). 6. Emissions from composting facilities are if at all only minimally monitored. However, there are states like the state of California, that view composting as a burden on the environment as well. This problem could be solved by locating composting facilities adjunct to WTE facilities that will remove the toxins from the air. 7. The only noise level that is of consideration are the trucks delivering the waste. Many facilities in Europe are located within the cities within very close proximity to residential living and besides delivery trucks the noise level is contained by the enclosed buildings. 8. Unless the composting facilities are fully enclosed the noise level is higher as equipment moves and operates outside including delivery trucks. 9. Modern WTE facilities (example mass burn) are enclosed facilities and due to the most stringent regulations have no odors to the outside. All air is channeled through a negative pressure system through the fluegas treatment process resulting in zero ?smell?. 10. The smell at composting facilities when not in fully enclosed buildings (most composting facilities are open air) can reach detrimental levels. This is either due to anaerobic ?nests? of methane and/or other odorous gases that develop and are released during the composting process (turning) and/or are produced by substances that should not be composted in the first place (animal derived products etc ? biogas facilties should handle this kind of waste). 11. Modern WTE facilties (mass burn) are zero water discharge facilties by regulation. 12. There is no strictly enforced regulation that hinders water discharge from composting facilties. In addition open air composting facilties have no adequate water collection systems. Overall many products that are composted in the Pacific Northwest should not be composted (papers as they contain bleach, animal products, etc). Compared to heavily controlled, regulated and monitored WTE (mass burn) facilties, composting facilties run a risk of contamination through certain types of food wastes, household toxins that find their way into the composting bin, garden chemicals etc. Composting facilties also cost society a lot of money ? the better operating the more expensive. Bottom line composting should be done to a certain amount and for certain products as the process can produce viable soil for specific types such as forestry and maybe in vineyards. WTE facilties turn a mostly biogenic (renewable) resource into reusable end products and most importantly into renewable energy in a very controlled environment that is strictly monitored and enforced. Compared to landfilling which disposes of the biogenic and other resources with minimal (at best 50% methane recovery), WTE (mass burn) pulls all the energy content which is mostly biogenic (renewable) out of the waste delivering valuable energy to businesses and residences.

Does anyone have data to show the relationship between oxygen and/or CO2, and the population of active bacteria and/or fungi? If we're in business for profit, and committed to our neighbors and the environment, doesn't it make sense to do the research, to make our decisions based on hard evidence? In most businesses, one of the first things a manager does is to look around and see how many people are working. With our primary production workers being microbes, doesn't it make sense to be checking up on the microbes? Sure, doing the direct estimates requires a 1000X microscope with Epi-Fluorescence; and making up the phosphate buffers, doing the serial dilutions and then staining. And maybe that is a lot less expensive than not knowing, less expensive than guessing and hoping. We adjust the RATE of air flow to try to hold the CO2 in the off-gas between 1 - 2%. Even then, there are times when the temperature pushes up over 160?F, even with the rate of air flow > 24 times the volume of the compost, in fresh air, every hour. Does anyone have hard data showing at what moisture level the microbial activity starts to decline, based on direct estimating of the population of active bacteria? And the same question applies to fungi; do fungi function as well at 30% moisture as 40 or 50 or 60% moisture content? Working Together to Create a Sustainable Environment, John A. Crockett, a.k.a.

Successful management is an "art" and must deal with the issues you raise. The heart of the discussion is whether composting is "aerobic" or "anaerobic" in nature. During the composting process, O2 level will fall during periods of rapid microbial action, and between aeration events. From beginning to ending, the process generally becomes more and more aerobic as the BOD is metabolized. But if the process goes anaerobic, it generates a huge malodor and requires careful management to obtain aerobic status and proper management to become aerobically stabilized. The fact that low O2 levels are found in the center of compost piles during the middle of the composting process is simply "composting" under aerobic conditions. Too high aeration cools excessively, or enough aeration replaces O2, removes CO2 and water, and cools appropriately. But the process and product are "aerobic". Please focus on the big picture. Composting should never be used to describe an anaerobic process.

Crockett Sent: Wednesday, March 11, 2009 11:56 AM To: U.S. Composting Council listserve Subject: [USCC] aerobic composting, definitiion There is a lot of discussion on anaerobic and aerobic. What is the specific definition of aerobic composting in terms of the oxygen level in the compost? Is it 5% oxygen, 10%, 15%? What CO2 levels are still acceptable under the definition of "aerobic"? OR, is there no such definition? I strive for 1 - 2% CO2 in the off-gas, and I base that on assaying the active bacteria population, and the fact that we've gotten our best populations of active bacteria when the CO2 in the off-gas was less than 4%. We've also had many cases where in the early days of the process, we've sustained temperatures > 150?F with a rate of aeration > 25 times the volume of the compost, in fresh air, every hour, in order to hold the CO2 within those limits.

While both processes reduce the volume of input material through heat, incineration is a heat sink while combustion produces heat for other uses. There might be several factors favoring composting or combustion for different sites. But what can be used as a common denominator for comparison? The most likely one is net profit. It is more likely to be an ongoing (sustainable) venture if the material is composted or combusted? In properly designed systems I don't see much opportunity for pollution in either system, or not one over another. Combustion can be clean enough that you can't tell if the facility is operating by looking at the stack.

Compared to heavily controlled, regulated and monitored WTE (mass burn) facilties, composting facilties run a risk of contamination through certain types of food wastes, household toxins that find their way into the composting bin, garden chemicals etc. Composting facilties also cost society a lot of money ? the better operating the more expensive. Bottom line composting should be done to a certain amount and for certain products as the process can produce viable soil for specific types such as forestry and maybe in vineyards. WTE facilties turn a mostly biogenic (renewable) resource into reusable end products and most importantly into renewable energy in a very controlled environment that is strictly monitored and enforced. Compared to landfilling which disposes of the biogenic and other resources with minimal (at best 50% methane recovery), WTE (mass burn) pulls all the energy content which is mostly biogenic (renewable) out of the waste delivering valuable energy to businesses and residences.

Crockett) Date: Mon, 16 Mar 2009 21:12:52 -0400 Subject: [USCC] What is "Aerobic" as far as % oxygen content Message-ID: <200903170112.n2H1Cu3s010262@omr5.networksolutionsemail.com> I agree with Rufus Chaney when he says there is a lot of "Art" to composting. I'll add, that I think a good composting process manager has a lot of intuition, usually (L)Earned through years of hands on experience, and continually asking how we can improve the process. We adjust the rate of air flow, trying to hold the CO2 level between 1 - 2%, and often that requires, with the feedstocks and the way we pre-process and manage our compost, to require over 20 times the volume of compost, in fresh air, every hour. And even with that rate of air flow, we often see temperatures > 160?. We adjust the flow rate, and believe that on/off aeration is no better than it would be for us. I think I would have a real hard time functioning if some of the time the air I breath had less than 15% oxygen in it, so we use continuous aeration, 24/7. While we call it "forced" aeration, often the "force" is < 0.300"wc; and often a change of 0.030"wc will massively change the rate of flow. Of course we need to use a fine digital manometer to monitor pressure / vacuum in those ranges. And, certainly we often get significant foul odors in the off-gas from early stage food composting, even with the oxygen level ? 17%. Since we use negative pressure on the early stage compost, we have custody of that off-gas, and turn around and send it through older compost, which still needs aeration, and very conveniently also doubles as a dynamic bio-filter. At least, I've read that all fungi are strict aerobes, meaning that they need oxygen. I still don't know what the tolerance range is for oxygen for optimal fungal activity, and if anyone knows that, I would appreciate that information. Our first oxygen depletion research was over 13 years ago, and we found that the microbes could crash the oxygen level from 19% down to 2% in 15 minutes. Much of that information has been available to everyone with internet access, since we opened www.magicsoil.com in May of 1998. Of course, how fast the microbes crash the oxygen level in the absence of full time forced aeration probably depends on how many active microbes are consuming oxygen, are working at getting the composting job done. If composting is a "profession", it seems to me that there ought to be a definition for "aerobic" defined as a % oxygen content, and that definition ought to be based on what level will support a specific population of bacteria and / or fungi, whether that level of active bacteria be 5E+6, or 3.0E+9, per gram, dry weight. Then, complicating that is particle size. We shred to < 1/8" because turn around time translates to how quickly we can use that space for more incoming material.

It looks at the closure of 500 landfills in Germany, waste reduction legislation, creation of recycling facilities, pretreatment of MSW, and the picture makes alot of sense.

This isn't an" either-or" situation. We need clean compost AND we need renewable energy. http://www.greenconversionsystems.com/Power%20Point%20Presentations/German%20regulatory%20Perspective%20-%20PPT%20-%20short.ppt#261,6,Steps of Development (2) Maureen Reilly .................... > > >From Dr. Helmut Schnurer ? former Head of Waste Management at the German > Federal Ministry for the Environment.

Crockett Sent: Friday, March 13, 2009 12:44 PM To: U.S. Composting Council listserve Subject: [USCC] Oxygen level in compost & Eliot's comments I understood Eliot to say that he BELIEVES the oxygen level ought be at least 10% in the compost. Does anyone have data to show the relationship between oxygen and/or CO2, and the population of active bacteria and/or fungi? If we're in business for profit, and committed to our neighbors and the environment, doesn't it make sense to do the research, to make our decisions based on hard evidence? In most businesses, one of the first things a manager does is to look around and see how many people are working. With our primary production workers being microbes, doesn't it make sense to be checking up on the microbes? Sure, doing the direct estimates requires a 1000X microscope with Epi-Fluorescence; and making up the phosphate buffers, doing the serial dilutions and then staining. And maybe that is a lot less expensive than not knowing, less expensive than guessing and hoping. We adjust the RATE of air flow to try to hold the CO2 in the off-gas between 1 - 2%. Even then, there are times when the temperature pushes up over 160?F, even with the rate of air flow > 24 times the volume of the compost, in fresh air, every hour. Does anyone have hard data showing at what moisture level the microbial activity starts to decline, based on direct estimating of the population of active bacteria? And the same question applies to fungi; do fungi function as well at 30% moisture as 40 or 50 or 60% moisture content? Working Together to Create a Sustainable Environment, John A. Crockett, a.k.a.

Crockett) Date: Thu, 19 Mar 2009 11:33:16 -0400 Subject: [USCC] Oxygen In Composting Message-ID: <200903191533.n2JFXFSN003641@omr15.networksolutionsemail.com> Regarding oxygen in composting, Eliot Epstein said: "Take a look in my book The Science of Composting pg. 27" which I just did, and to me, that does not answer my question. It shows two graphs, Y axis oxygen, Y' axis CO2, and the X axis days. I saw nothing on the rate of air flow. The oxygen could have been held at any level by adjusting the RATE of air flow. I am well aware that oxygen consumption varies with the population of oxygen consumers, and that there are many management practices that affect the population, and that early in the process, there seems to be the greatest opportunity for the highest populations of active bacteria. If the oxygen is low, it is easy enough to provide more aeration, a greater rate of air flow, provided the aeration system has been designed to enable varying the RATE of air flow, vary the cubic feet per minute. It is very easy to maintain oxygen at any given level by varying the RATE OF AIR FLOW to coordinate the aeration with the microbial oxygen consumption. I want, and firmly believe that we need info on population and / or bio-mass of active bacteria and fungi at various concentrations of oxygen and/or CO2. We're frequently needing to provide over 13X, and 23X is not uncommon, the volume of compost, in fresh air every hour, to hold the CO2 down between 1 - 2%, and at the same time we're sustaining temperature < 155?F. Since I am na?ve enough to believe that improving the composting process is going to require being a lot more aware of what is happening in the composting mass, and how that changes with our changing the oxygen and moisture levels, turning to homogenize, to improve porosity, while also getting the porosity to be more uniform, while also averaging out the microbial distribution throughout the composting mass; I just spent about 15 minutes looking at a tiny sample at 40X (microscope magnification) and found it interesting to see what appears to be a lot of fungal hyphae showing up. I consider this sample to still be 'early stage', since the heating and oxygen consumption suggests to me that there is a lot of bacterial activity. Can fungi generate nearly as much heat at bacteria? I don't know! So, we're back at the question: What is the definition of "aerobic" in concentration of oxygen in the composting mass? Is there any definitive percentage of oxygen that qualifies as aerobic? And if so, what is the basis for that definition? I suggest that maybe 15% oxygen be accepted as aerobic and that ? 17% is better; and that CO2 should be ? 5% with ? 2% being a lot better. I think this is what the microbes 'need' to be able to meet the challenges that homo sapiens have created, that we're depending on them to solve.

How can we go beyond the most basic steps of: 1. front end (pre-processing) to reduce particle size to < ?", 2. maintain moisture content ? 40% (does anyone have good data to show what the best moisture content is to promote fungal activity?) 3. Maintain oxygen ? 15%, and again, does anyone have solid data on what the minimum oxygen concentration is for good fungal activity? 4. Utilization of Progressive Inoculation Technology. In composting we have a major advantage over most other industries in that our primary production workers come free, are willing to work 24/7, are non-unionized, work Sundays and holidays. Of course, I am talking about the microbial master composters. And, we know that they have the ability to raise a big stink, if not treated respectfully. With that going for us, doesn't it make sense to figure out how to optimize their population and productivity? I can be a slow learner. It was just yesterday that I first looked at a sample of compost, a few particles, no serial dilution in phosphate buffer, but rather putting a tiny bit of compost on a microscope slide, and studied it a little at 40X, no cover slip, I did not compact it at all, which meant that I had to move the stage up and down because of the limited depth of field, to focus in on the hyphae. It's fascinating, and very humbling. I have so much to learn about composting. Because of the limitations of depth of field, photographing may be very difficult. I'll see if I can prolong the exposure time to increase the depth of field / focus, for better images. I am looking for a database, that we can measure our management against, to see how we can significantly improve the population of active fungi, to speed up turn around time. It seems to me that earning public respect calls for our being really professional, and that calls for learning a lot more about the composting process, including learning about our microbial master composters.

How can we go beyond the most basic steps of: 1.??? front end (pre-processing) to reduce particle size to < ?", 2.??? maintain moisture content ? 40% (does anyone have good data to show what the best moisture content is to promote fungal activity?) 3.??? Maintain oxygen ? 15%, and again, does anyone have solid data on what the minimum oxygen concentration is for good fungal activity? 4.??? Utilization of Progressive Inoculation Technology. In composting we have a major advantage over most other industries in that our primary production workers come free, are willing to work 24/7, are non-unionized, work Sundays and holidays.? Of course, I am talking about the microbial master composters.? And, we know that they have the ability to raise a big stink, if not treated respectfully. With that going for us, doesn't it make sense to figure out how to optimize their population and productivity? I can be a slow learner.? It was just yesterday that I first looked at a sample of compost, a few particles, no serial dilution in phosphate buffer, but rather putting a tiny bit of compost on a microscope slide, and studied it a little at 40X, no cover slip, I did not compact it at all, which meant that I had to move the stage up and down because of the limited depth of field, to focus in on the hyphae.? It's fascinating, and very humbling.? I have so much to learn about composting.? Because of the limitations of depth of field, photographing may be very difficult. I'll see if I can prolong the exposure time to increase the depth of field / focus, for better images.? I am looking for a database, that we can measure our management against, to see how we can significantly improve the population of active fungi, to speed up turn around time. It seems to me that earning public respect calls for our being really professional, and that calls for learning a lot more about the composting process, including learning about our microbial master composters.

That is what my graph shows. I also pointed out that based on our 30 years of experience when oxygen levesl dropped below 5% we had a significant number of zones with little or no oxygen and were anaerobic. In thise cases we were able to measure small amounts of methane. Hence we recommended that piles (windrows) maintain oxygen levels above 10%. Higher levels were acceptable as long as the piles did not cool off appreciably and were able to maintain temperatures needed for pathogen destruction. As a point of interest my Ph.D thesis was on oxygen and carbon dioxide in soil in relation to the potential for organic matter decomposition. This was in 1955. Since then many excellent papers were written. There is a large volume of literature on popultion trends during composting. From the 1980s by Strom, finstein and Morris in 1974, Poincelet, 1977,Britton and Droffner in 1994, Palmisano in 1996, Walke, 1975, Epstein 1997 etc. etc., etc. Eliot -----Original Message----- From: compost-bounces at mailman.cloudnet.com [mailto:compost-bounces at mailman.cloudnet.com] On Behalf Of John A. Crockett Sent: Thursday, March 19, 2009 11:33 AM To: U.S. Composting Council listserve Subject: [USCC] Oxygen In Composting Regarding oxygen in composting, Eliot Epstein said: "Take a look in my book The Science of Composting pg. 27" which I just did, and to me, that does not answer my question. It shows two graphs, Y axis oxygen, Y' axis CO2, and the X axis days. I saw nothing on the rate of air flow. The oxygen could have been held at any level by adjusting the RATE of air flow. I am well aware that oxygen consumption varies with the population of oxygen consumers, and that there are many management practices that affect the population, and that early in the process, there seems to be the greatest opportunity for the highest populations of active bacteria. If the oxygen is low, it is easy enough to provide more aeration, a greater rate of air flow, provided the aeration system has been designed to enable varying the RATE of air flow, vary the cubic feet per minute. It is very easy to maintain oxygen at any given level by varying the RATE OF AIR FLOW to coordinate the aeration with the microbial oxygen consumption. I want, and firmly believe that we need info on population and / or bio-mass of active bacteria and fungi at various concentrations of oxygen and/or CO2. We're frequently needing to provide over 13X, and 23X is not uncommon, the volume of compost, in fresh air every hour, to hold the CO2 down between 1 - 2%, and at the same time we're sustaining temperature < 155?F. Since I am na?ve enough to believe that improving the composting process is going to require being a lot more aware of what is happening in the composting mass, and how that changes with our changing the oxygen and moisture levels, turning to homogenize, to improve porosity, while also getting the porosity to be more uniform, while also averaging out the microbial distribution throughout the composting mass; I just spent about 15 minutes looking at a tiny sample at 40X (microscope magnification) and found it interesting to see what appears to be a lot of fungal hyphae showing up. I consider this sample to still be 'early stage', since the heating and oxygen consumption suggests to me that there is a lot of bacterial activity. Can fungi generate nearly as much heat at bacteria? I don't know! So, we're back at the question: What is the definition of "aerobic" in concentration of oxygen in the composting mass? Is there any definitive percentage of oxygen that qualifies as aerobic? And if so, what is the basis for that definition? I suggest that maybe 15% oxygen be accepted as aerobic and that ? 17% is better; and that CO2 should be ? 5% with ? 2% being a lot better. I think this is what the microbes 'need' to be able to meet the challenges that homo sapiens have created, that we're depending on them to solve.

Bokashi loosely translates to "fermented organic matter", and 'organic matter' is referring to the substance used when infusing the microbes (bran, rice hulls, etc).? I prefer the terms "starter bokashi" and "finished bokashi", the former is bokashi and the latter is so-called (finished) bokashi compost.? Just using 'bokashi' and 'finished bokashi' will no doubt lead to confusion, some people would take it to mean the bokashi is 'finished' fermenting. You wrote: "Consider the STA seal of approval. It requires a showing that the material actually composted at 55C or above to obtain the benefits of composting, not some arbitrary claim of the submitter." Are you saying that anaerobic fermentation and decomposition (using bokashi) can not produce as high quality end-product as 'finished' compost?? If so please read the attached Soil Foodweb International (SFI) evaluation of their own assays using finished bokashi. When making the finished bokashi used in the SFI assays 'Osprey Landing' used traditional bokashi methods:? Anaerobically fermenting food scraps for some weeks (usually 3-6), then burying the fermented food scraps in soil so it may finish decomposing.? After some weeks (usually 3-8) the buried fermented organic matter has decomposed and is ready to use.? At that state the decomposed fermented organic matter could be called 'finished bokashi' and should be rife with microbes, etc, the full "Soil Foodweb" (SFW) and it should stable, contain humus, etc. The finished bokashi is dug up and use just like compost, or left in place to enrich the soil.? High quality finished bokashi can rival quality compost in terms of biology.? Finished bokashi can have bacteria, fungi, nematodes, protozoa, earthworms, etc.? In other words finished bokashi may (or may not) have the full SFW, just like compost may (or may not) have the full SFW.? Though I assume if the fermented organic matter was buried in infertile soil it would have few organisms besides those used to ferment the orgaic matter.? But I guess the same could be said about compost (as lacking the full SFW) when making compost on infertile soil... Excerpt from the SFI evaluation of their assays on finished bokashi: < http://www.ospreylanding.ca/explanation%20letter%20from%20swf.pdf > [PDF] "All of the test results of your EM sample are excellent or very good.? A higher level of fungi may be beneficial for garden soils but there is a good amount present to work with that could be raised with the addition of some fungal foods. This sample has a very good bacterial and fungal foundation but the levels of nutrient cyclers ? the protozoa and nematode ? are exceptionally good.? The result of? the very healthy food web found in your EM sample is the potential for very high rates of nitrogen cycling that will support high yields in heavy feeding plants such as corn and potatoes.? Our test results of your sample point to a very healthy and biologically rich soil." And here is a link to the SFW report: < http://www.ospreylanding.ca/Soil%20Foodweb%20Lab.pdf > [PDF] Chris ------------------------------------------------------------------------------ PREVIOUS MESSAGES IN TOPIC BELOW ------------------------------------------------------------------------------ Dear USCC folks: I can see some of the old experts on composting spinning in their graves on these "anaerobic composting" claims. It is not correct to say "anaerobic composting". As Eliot Epstein noted, composting is by definition an aerobic thermophilic process. Not mesophilic like anaerobic digestion at 35C. But 55C or above to kill pathogens and obtain aerobic stabilization. Anaerobic digestion is a useful process to generate methane and reduce mass of an unstable biomass. But it does not attain the stability of aerobic processing. Recent trials of thermophilic anaerobic digestion (to obtain pathogen kill and stabilization) produced putrid end products which were not ready to go to land. But thermophilic aerobic digestion gave a low odor product from input sewage solids. Just no energy recovery historically used to power pumps at POTWs. And their product is not ready for commercial application; rather normal controlled land application of the wet or dewatered product. Composting yields a semi-dry friable product ready to mix in soils for many uses. If you still think it appropriate to use "anaerobic composting", please read some of the classic texts and official documents on composting and present some rationale to justify the use. Don't just say that some particular group use it for the commercial benefit of using the "composting" name. That is simply cheating as sometimes occurs with commercial interests. Consider the STA seal of approval. It requires a showing that the material actually composted at 55C or above to obtain the benefits of composting, not some arbitrary claim of the submitter. Regards, Rufus Chaney Beltsville, MD. -----Original Message----- From: compost-bounces at mailman.cloudnet.com [mailto:compost-bounces at mailman.cloudnet.com] On Behalf Of Steve Diver Sent: Monday, March 09, 2009 1:46 PM To: Compost Discussion List Subject: Re: [USCC] What is Anaerobic Composting Some of the EM Bokashi Composting and Bocashi Composting (sans EM) piles are covered and allowed to ferment under anaerobic conditions, but these are geared to fermentative anaerobic not putrefactive anaerobic.

Some say that you can detoxify the juglone if you compost long enough (e.g., > 6 months). Haug even provides energy values of black walnut for use as chips in biosolids composting. See some of the comments below. The West Virginia University site says: The largest concentrations of juglone and hydrojuglone (converted to juglone by sensitive plants) occur in the walnut's buds, nut hulls, and roots. However, leaves and stems do contain a smaller quantity. Juglone is only poorly soluble in water and thus does not move very far in the soil. Leaves, bark, or wood chips of black walnut should not be used to mulch landscape or garden plants. Even after a period of composting, such refuse may release small amounts of juglone. http://www.wvu.edu/~agexten/hortcult/fruits/blkwalnt.htm The Purdue website also says that composting may not completely break down juglone. http://www.hort.purdue.edu/ext/HO-193.pdf From an Ohio State University Extension Fact Sheet: Walnut leaves can be composted because the toxin breaks down when exposed to air, water and bacteria. The toxic effect can be degraded in two to four weeks. In soil, breakdown may take up to two months. Black walnut leaves may be composted separately, and the finished compost tested for toxicity by planting tomato seedlings in it. Sawdust mulch, fresh sawdust or chips from street tree prunings from black walnut are not suggested for plants sensitive to juglone, such as blueberry or other plants that are sensitive to juglone. However, composting of bark for a minimum of six months provides a safe mulch even for plants sensitive to juglone. (This pub also lists plant species and their sensitivity/tolerance.) http://ohioline.osu.edu/hyg-fact/1000/1148.html Bonnie Appleton et al. says one can detoxify black walnut leaves in a compost pile. http://www.ext.vt.edu/pubs/nursery/430-021/430-021.pdf My recommendation would be: 1. Don't use significant quantities of black walnut (and a number of other such trees that produce allelopathic compounds (e.g., red cedar) if you plan on applying finished compost to sensitive specieis 2. If you have incorporated walnut chips/sawdust into the compost pile, continue to process for longer than usual 3. Use the finished product only on tolerant species Greg At 10:04 PM 3/25/2009, you wrote: >Hi - questions on juglone. >I have some black walnut wood shavings.
