Remix Scheduling During Composting Based on Moisture Control

Abstract

Equations for scheduling remixing and water additions required at remix to maintain specific moisture levels during composting were developed. Analyses of compost systems for various levels of compost mixes and operational temperatures were completed. Results indicated a weekly (or more often) mix schedule was needed during the period of composting when mixes had decomposition rates greater than 0.05 kg/kgco.day. Use of inert bulking agents decreased the number of remixes required and increased time between mixing.
