Waste, also referred to as rubbish, trash, refuse, garbage, or junk, is unwanted or unusable materials. They are byproducts of some economically important products, agricultural crops or living being remains. Today, due to availability of sophisticated instruments, man is increasingly exploring nature to produce a number of products to be used in day-to-day life. This exploitation is producing a huge amount of waste.

Some wastes are degradable in nature whereas many are non-degradable. They are dumped either in the soil or in the sea. Dumping is not the solution to waste removal. If these wastes are not properly treated, they may then pollute groundwater or seawater. One way to reduce the risk of pollution is chemical or mechanical treatment of wastes, which is quite costly. Another, cheaper way is use of micro- or macro-organisms. Use of microorganisms requires their expensive cultivation in the laboratory and is also highly sensitive to degradation conditions. On the other hand macroorganisms such as earthworms are freely available in nature and their rearing is also cheap.

Conversion of waste materials kept in heaps via earthworms into valuable products is known as vermicomposting and its product is called vermicompost. Efficiency of this process depends on a number of factors including size of waste, size of pile, nature of waste, amount of moisture present, ratio of waste and dung, availability of sufficient protection measures, species of earthworms to be used, presence of any toxic material in waste etc. Selling of worms itself generates employment especially in rural areas.

In this context, we call for papers addressing research on the above-mentioned factors affecting the rate of vermicomposting. The outcomes will help planners to develop policies in this regard and also guide researchers to make this process more efficient and economic.
