Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste.
The soil is analyzed and its pH is adjusted (if needed). The soil is moisturized (if needed) to facilitate the activity of decomposers. The soil is then covered with a thin layer of slowly decomposing material (known as the weed barrier), typically cardboard. This suppresses the weeds by blocking sunlight, adds nutrients to the soil as weed ...

Commercial composting begins with a manual breakdown of the materials using a grinder or other machine to initiate the process. Because at-home composting usually occurs on a smaller scale and does not involve large machinery, these materials would not fully decompose in at-home composting.
Unlike the forest floor, where leaves decompose and put nutrients back into the soil, leaves piling up and breaking down can harm your turf. Lawns need access to sunlight and airflow, just like ...
Decomposing pig showing signs of bloat and discoloration, a result of microbial proliferation within the body.. Microbiology of decomposition is the study of all microorganisms involved in decomposition, the chemical and physical processes during which organic matter is broken down and reduced to its original elements.
