Feb 2, 2018 · The objective of this study was to examine the feasibility of sewage sludge composting using a simple aeration method. Two consecutive composting trials (run A and run B) using Japanese sludge and woodchips (1:1, v/v) were conducted in cubic boxes (0.45 × 0.45 × 0.45 m3) made by plywood at Okayama University. Air was forced up through small holes perforated on two open-ended parallel PVC
Oct 27, 2015 · It appears that composted SS and green/dry plant waste at 1:2 and 1:3 proportions pose no threat to soil or plant quality if used in agriculture or land restoration, and pH and electrical conductivity were within the permissible limits. In order to use sewage sludge (SS) composts in agriculture, it is extremely important to estimate the quality of compost products. The aim of this study was to
May 5, 2015 · Introduction. Composted organic waste from households, businesses, yards and parks, food processing and agricultural waste, as well as sewage sludge from municipal sewage treatment plants contains a host of valuable plant nutrients.
