  • 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 ...

For example, in the late 1980s and early 1990s, it was the perceived landfill crisis that led to state bans on disposal of yard trimmings. Composting also has benefitted from a push to meet recycling goals, which has prompted states and local governments to go beyond yard trimmings and into such ...

  • Introduction of composted digestates in agriculture

    Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

  • 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 ...

  • 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 ...
