Pilot-scale evaluation demonstrates rapid biowaste conversion into nutrient-rich compost within 7–10 days, suggesting a viable industrial recycling pathway.
In this study, a pilot-scale in-vessel composter was used to treat a mixture of industrial biowaste, with soybean curd residue and saw dust as the major substrates. The composter is capable of treating up to 350 tons/month of waste, producing up to 150 tons/month of high-quality compost within a retention time of 7-10 days. The final compost has an average nitrogen-phosphorus-potassium content of 6%, moisture content of 28%, pH of 6.1, organic matter of 68%, and carbon-nitrogen ratio of 19:1. It also has a good amount of humic acid and macronutrients. Composts from all stages of the composting process-pre-mix, directly after discharge, after one-month of curing, and right before packaging-were evaluated with metagenomic analysis to identify the microbes that may add value to the compost.
