Extent and rate of biodegradation of different organic components in municipal solid waste

0
Rates and extent of biodegradability of four different organic components of municipal solid waste (leaf litter, newspaper, magazine paper and A4 sheet) were evaluated under optimum conditions. Total solids (TS) removals in biotic samples ranged from 74.7% to 78.8% while volatile solids removals ranged from 75.7% to 84.8%. Significant biodegradation of tannin–lignin was observed for all four components and removals ranged from 53% to 79.5%. Biodegradation rates were measured for all components and were found to fit second–order kinetics best. Biodegradation rate constants for all biotic samples ranged from 0.0317 to 0.0352 L/g–d. Control samples that had been autoclaved initially had higher biodegradation rates ranging from 0.0303 to 0.0537 L/g–d.
