Aerobic composting and vermicomposting processes were compared in the co-composting of durian shells citrus peels. For decomposers, microorganism catalyst from Land Development Department, i.e., LDD1 catalyst, earthworms used. The moisture contents peels 84.6% 77.3%, respectively, pH relatively low, as these are sources potassium. experiments utilized four different reactors: (100%) reactor 1; ...

The increase in global population and the resulting economic activity have led to major environmental problems such soil, air, water pollution. This rise growth has resulted increased use of chemical fertilizers boost agricultural production loss microbiological physicochemical equilibrium soil. These factors an need for eco-friendly products that help enhance soil's physical, chemical, charact...

Sludge drying reed bed (SDRB) is a technology adopted to treat sludge from septic tanks, latrines, or anaerobic and aerobic reactors. The sludge is loaded by pumping on vegetated beds, and treated by a combination of physical and biochemical processes. The dewatering of the sludge is due to a combined effect of drainage and evapotranspiration. The organic matter reduction of the sludge is drive...

This discussion explores the possibility of having a measure of the biodegradable organic carbon content in solid wastes. Currently, indirect measures for determining the concentration of biodegradable organic matter are being used and most of them are based on respiration indices (oxygen consumption or carbon dioxide production) or chemical parameters (volatile solids or total organic carbon)....

Treatment of domestic waste is generally carried out by activated sludge process. The waste solid sludge can be treated by various aerobic and anaerobic treatment processes. Aerobic treatment methods need space and time. Anaerobic treatments have advantages such as space utilization and production of fuel gases such as methane. Up flow anaerobic sludge digester or fluidized bed digester can be ...

AIMS The objectives of this study were to determine the changes of microbial properties of pig manure collected from pens with different management strategies and composted using different turning and moisture regimes; relate their association with humification parameters and compost temperature; and identify the most suitable microbial indicators of compost maturity. METHODS AND RESULTS Six ...

1. A SUMMARY OF THE GHG IMPLICATIONS OF COMPOSTING During composting, microbial decomposition aerobically transforms organic substrates into a stable, humus-like material (Brown and Subler, 2007). Although small-scale composting, such as backyard composting, occurs across the United States, WARM models composting only in central composting facilities with windrow piles because data for small-sc...
