Composting of < 100 mm Fraction of Municipal Solid Waste

Abstract

A low cost solution for management of municipal solid waste in small municipalities was investigated; composting experiments were done using domestic waste. Particles > 100 mm were removed, the screened substrate ( < 100 mm) was used for composting experiments on static piles. The results have shown that the size of waste does not affect composting. Though the inert material left greatly adds to the porosity, rainfall does not markedly affect the process; in fact excessive dryness gave the least stable end product, and total nitrogen, ammoniacal nitrogen and phosphorus content were the best pointers to the instability.
