Effect of Passive and Forced Aeration on Composting of Market Solid Waste
The book chapter discusses the influence of aeration on the decomposition of solid wastes available on the market. The vegetable waste, paper waste, and sawdust as a filler were mixed intensively in a ratio of 75:10:15. The temperature of composting mass inside the reactors was recorded intermittently daily. The weights of total sample and volatile solids were measured for both passive and forced aeration composting tests before and after composting the mixed waste. The temperature rose to a maximum of 52°C with passive aeration and 54°C with forced aeration. The percent decrease in the total sample was higher with forced aeration than with passive aeration. The volatile solids reduced over time at the end of these tests. The degree of volatile solids degradation of the mixed waste over time by the forced aeration was determined for a series of the composting processes. The amount of volatile solids and total sample were determined at 2- to 4-day intervals. The percent reduction in volatile solids and total sample was found to be 4 to 55% and 3 to 68%, respectively. The percent reduction in volatile solids increased with time. The chapter helps to understand the recycling possibility of the mixed waste in the form of compost.
