Effect of granular porous media on the composting of swine manure

Phytotoxicity and speciation of copper, zinc and lead during the aerobic composting of sewage sludge

“…This might be due to the usage of different compost curing progresses. However, similar to Kim et al [41], the changes of Pakchoi germination and root growth were highly correlated to progressive degradation of OM and DOC ( Table 4). The organic matter and dissolved organic carbon during composting were important factors in compost maturity [42,43] and controlling phytotoxicity of compost [20,44].…”

“…The pH value did not significantly related to the Pakchoi germination and root growth (Table 4), which varied from the data of Kim et al [41]. This might be due to the usage of different compost curing progresses.…”

Biochar as bulking agent for poultry litter composting

“…Bioavailable C can reduce N losses during the composting of organic wastes with high-N concentrations [2], but may also have a negative influence on compost stability [4] and N availability, which may introduce N nutrition problems for organic farming systems [5]. Inorganic bulking agents do not decompose during the composting process and could be reused [3,6]. However, rubber chips from old tires used for sewage sludge composting could not adsorb sufficient water to maintain optimum moisture levels [3].…”

Home Composting Using Facultative Reactor

“…Taking that into consideration, some studies have emphasized that in order to retain heat and keep ideal temperatures, the reactor walls should be covered with thermal insulating material [14,15,[20][21][22]. Several studies used OSW coming from vegetable, fruit, olive bagasse, grape bagasse and olive bagasse, waste which is widely found in rural areas.…”
