In-Vessel Composting of Municipal Solid Waste with Varied Press Air and Organic Fraction

摘要

This research aims to evaluate the performance of laboratory-scale in-vessel composting bioreactor for the organic wastes fraction of municipal solid wastes in Faculty of Science and Technology, Rajamangala University of Technology Phra Nakhon, Bangkok. The bioreactor was special designed and used for this research with working volume of the reactor was 10 L, and it was operated with varied press air and organic wastes fraction. Obtained results showed that organic fraction of municipal solid waste could be composted successfully in 20 days. The qualities of compost in terms of the ratio of carbon to nitrogen (C/N), temperature, pH value, moisture content (%M), total nitrogen (%N), potassium (K_2O), phosphorus (P_2O_5), organic matter (%OM), and organic carbon (%OC) were investigated.
