Small Scaled Home Composting Machine and Use of Trichoderma As A Bio-Fertilizer Agent

Abstract

Organic waste composting is the leading way of recycling. By controling the microbial aerobic decomposition process of organic waste organic fertilizer can be otained. In the present paper a new design of home composter machine useful for a family of 4 to 6 people is discussed. A shredder with effective cutting angle and Trichoderma, a biofertilizer agent, are the main features af the machine. The motive behind using shedder is to cut solid waste into very small pieces and reduce the composting reaction time. Waste after cutting is decomposed by Trichoderma in the presence of required air circulation and temperature to form organic fertilizer. Trichoderma degrades organic matter and also produces nutrients and growth regulating compounds which is useful for plants. For efficient composting, other than better air circulation, frequent turning of waste, optimum level of moisture content use of some bulking agents like sawdust biochar were also taken in consideration. It resulted in the disposal of waste at the source and opening new economical avenues by producing fertilizer at home.
