  • Composting

    Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

  • Design and performance of a simulated feedstock for composting experiments

    This paper reviews the composition and performance of simulated feedstock mixtures previously employed in composting research, and presents a new simulated feedstock. The new feedstock was prepared using readily available dry ingredients - ostrich feed pellets, office paper, finished compost and woodchips - representing the substrate, amendment, seed, and bulking agent components of a composting ...

  • Evaluation of composting performance of mixtures of chicken blood and maize stover in Harare, Zimbabwe

    Background: Chicken processing results in the production of a lot of blood which if disposed on land poses environmental hazards in terms of land pollution. The aim of the study was to develop an aerobic composting process for chicken blood to produce a nitrogen-rich soil amendment for use in agriculture. The study involved composting of blood and maize stover of different proportions (10%, 30%, ...

  • Improving Performance · Processing Equipment Retrofit at Florida Composting Facility

    PALM Beach County, Florida may have been confused during the last presidential election but there is no confusion about management of the county’s organic waste stream. Palm Beach County has a population of approximately 1.2 million people and the Solid Waste Authority of Palm Beach County is responsible for the management and disposal of the solid waste that is generated here. The authority ...


  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Composting Organics In Canada

    Organic waste diversion is spreading steadily across Canada, with greater tonnages being collected through residential curbside pick ups and depots, as well as from food processors and others in the industrial, commercial and institutional sectors. At the federal level, Canada’s government has a small presence in organics diversion and composting. It offers occasional financial support, as ...

  • Calculating capacity at composting sites

    The addition of new composting facilities or expansion of capacity at existing ones is becoming more and more difficult as feasible sites are taken out of circulation. This has created interest in maximizing the unit production of compost at composting sites so that they perform as efficiently as possible. The need is especially acute if physical expansion is not possible, but increases in ...

  • Operator insights: compostable products

    Compostable products are increasingly a part of the formula when companies, institutions, municipal programs and special events decide to go green, usually to implement a food scraps diversion program. Due to increasing demand, the compostable products industry is growing rapidly, with many different options on the market. BioCycle has been covering developments in the compostable products ...

  • Composting Food Residuals on Campus

    Two professors at the University of Wisconsin-River Falls (UW-RF) have used their knowledge of organics recycling projects to implement a food residuals composting program on campus. “It just makes sense in the long run to divert these materials now and lay the groundwork for the future,” says Bob Butler of the Agricultural Engineering Department, who is working closely with Jerry Nolte, an ...

  • Troubleshooting the Compost Pile

    While composting is a biological process, we as composters must provide the microorganisms that do the work with the conditions they need to do their job. If there is a problem with the system, then look at it from the point of view of the microbe. What does that microbe need to function, and why isn’t it functioning correctly? Microorganisms need a source of energy organic feedstocks to feed on ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...

  • Microbial community composition and reactor performance during hydrogen production in a UASB reactor fed with raw cheese whey inoculated with compost

    This study investigated the microbial community developed in a UASB reactor for hydrogen production and correlated it to reactor performance. The reactor was inoculated with kitchen waste compost and fed with raw cheese whey at two organic loading rates, 20 gCOD/Ld and 30 gCOD/Ld. Hydrogen production was very variable, using an OLR of 30 gCOD/Ld averaged 1.0 LH2/Ld with no methane produced under ...

  • Modeling composting kinetics: A review of approaches

    Composting kinetics modeling is necessary to design and operate composting facilities that comply with strict market demands and tight environmental legislation. Current composting kinetics modeling can be characterized as inductive, i.e. the data are the starting point of the modeling process and determine the type of model used. It is argued that the inductive empirical approach has been ...
