Question

What percent of the moisture content is beneficial for biological breakdown of the waste?

• A. 40%
• B. 45%
• C. 50%
• D. 55%

Answer 1

The correct option is D 55%

The moisture content of the waste is considered as a single critical parameter for evaluating the efficiency of the bio-drying process. The moisture content influences microbial activity and biodegradation of the organic component during the bio-drying process. Despite the fact this technology is considered as a zero leachate approach, it is likely that a limited amount of free water may seep through the waste matrix and collected at the bottom of the bioreactor as leachate. Bio-drying has mostly been studied for MSW (municipal solid waste pulp and paper and, garbage residues and sewage sludge with 50–70% as the optimal initial moisture content range for the bio-drying process.
