The Process and Pathogen Behavior in Composting: A Review
نویسندگان
چکیده
Composting is defined as the biological decomposition and stabilization of organic substrates under aerobic conditions to allow the development of thermophilic temperatures. This thermophilic temperature is a result of biologically produced heat. Composting produces the final product which is sufficiently stable for storage and application to land without adverse environmental effects. There are many factors which affect the decomposition of organic matter in the composting process. Since the composting process is very intricate, it is not easy to estimate the effect of a single factor on the rate of organic matter decomposition. This paper looked at the main factors affecting the composting process. Problems regarding the controlling, inactivation and regrowth of pathogen in compost material are also discussed.

Effect of Composting Process on Some Chemical-Biological Properties and Heavy Metals Behavior of Municipal Sewage Sludge as Affected by Various Bulking Agents
The present study tries to investigate the effect of composting process on some properties and heavy metals status of two municipal sewage sludge (MSS) as affected by three different organic bulking agents (BAs) at three levels (10%, 25%, and 45% V/V). According to the results, the composting process could reduce the fecal coliform to class A, a reduction more obvious in treatments with BAs tha...

متن کاملEffectiveness of Composting as a Means of Emergency Disposal: A Literature Review
There has been a multitude of research conducted on different aspects of passively aerated windrow systems (PAWS) composting of mortality in the past several years. Early on, the research was concentrated on whether or not (PAWS) composting could actually dispose of animal tissue. Once that was determined, researchers began looking at optimization of the process (bulking material, type of syste...
