Moisture and particle size: optimal conditions for MSW composting

A study was done on the possibility of using municipal solid waste fro composting. It was shown that composting is limited by particle size and moisture. Optimal conditions for the process include piles measuring two meters high and three meters wide, a two over one mixture of fine particles and 50% humidity. In addition, it was shown that finer particles facilitate biodegradability and that moisture reaches its critical period after eight weeks.
