  • 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 ...

  • The influence of aeration system, temperature and compost origin on the phytotoxicity of compost tea

    Numerous studies have evaluated compost teas’ capacity to suppress plant disease, but no study has been made of possible compost tea phytotoxicity. In this study, 24 assays were carried out on compost tea produced from three different composts: one produced from bovine manure (M) and two others made from municipal solid waste but differing in the degree of stability (stable: MSW I and unstable: ...

  • Development of time-temperature probes for tracking inactivation during composting

    Performing compost quality assessment such as compost stability is quite necessary for rating the quality of horse manure and biowaste composts and meeting specific regulatory requirements on the composition and compost process. The aim of this study was to identify an appropriate feedstock composition for use in the production of high quality compost. The objectives were to (1) identify an ...

  • Development of time-temperature probes for tracking pathogen inactivation during composting

    Pathogen inactivation is expected to occur in compost if temperatures over 55°C (131°F) are maintained for at least 3 days, or 15 days in windrows. However, a literature review revealed pathogen survival in a significant number of processes appearing to meet the prescribed time-temperature criteria. It was hypothesized that pathogen survival may be due to the existence of undetected temperature ...

  • 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 ...

    A Vermont solid waste district utilized a defunct biosolids composting site to create capacity for processing food waste. The Vermont legislature instituted a progressive ban on organics in landfills via Act 148 in 2012. The Act includes the provision that transfer stations/drop-off facilities must accept food scraps by July 1, 2017. The Lamoille Regional Solid Waste Management District (LRSWMD) ...

  • Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide

    Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

  • 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 ...
