Solid waste management is an enormous task in developing nations all over the globe due to factors like poverty, population explosion, urbanization and lack of proper funding by the government. Disposal methods such as incinerator, landfill, pyrolysis and gasification are efficient but have negative impacts on the environment as well as threat to public health. Composting, when properly handled, is sustainable with various advantages such as production of biofertilizer, relatively low air and water pollution, low operational cost and income generation. The use of composting for bioremediation of contaminated soil has gained much ground in many developed countries of the world. However, composting when improperly designed could lead to methane production, odour emission and heavy metals build-up in the final product. This study reviews the sustainability of composting and its numerous advantages over other waste disposal options in developing countries.
