Biotransformation of Biodegradable Solid Wastes into Organic Fertilizers using Composting or/and Vermicomposting
This review discusses the differences between composting and vermicomposting of biodegradable solid waste. Solid waste management is a major challenge worldwide due to the rise in population and industrialization, leading to larger amount of solid wastes being generated. Biological process has been widely recognized in converting solid organic materials into environmental friendly and value add...
متن کاملEffects of Placement Conditions on Decomposition of Municipal Solid Wastes in Cold Regions
The effects of placement practices on decomposition of wastes were investigated at Anchorage Regional Landfill (Anchorage, Alaska) since 2002. Temperatures and gas concentrations of wastes placed at various seasons were monitored. Wastes were placed at sub-freezing temperatures during cold seasons. Waste temperatures generally increased upon placement. High variation was observed in waste tempe...
متن کاملAn investigation on the modelling of kinetics of thermal decomposition of hazardous mercury wastes.
The kinetics of mercury removal from solid wastes generated by chlor-alkali plants were studied. The reaction order and model-free method with an isoconversional approach were used to estimate the kinetic parameters and reaction mechanism that apply to the thermal decomposition of hazardous mercury wastes. As a first approach to the understanding of thermal decomposition for this type of system...
متن کاملSurvey of Hospital Solid Wastes Management in North of Iran
Background and Objectives: Disposal of hospital wates is a significant environemtal concerns, particularly in develoing regions of the world. Addressing this challenge relies on availability of detailed data on the current status of wate management. Mazandaran Province is located in southern coast of the Caspian Sea and thus its environmental status may directly influe...
متن کاملBioaccessibility of U, Th and Pb in solid wastes and soils from an abandoned uranium mine.
Bioaccessible U, Th, Pb and the 238U decay products 214Pb and 210Pb have been determined, using a modified Unified BARGE Method (UBM), in waste solids and soils from an abandoned uranium mine in South West England, UK. Maximum aqua regia extractable concentrations for U, Th and Pb were 16,200, 3.8 and 4750 μg g-1, respectively. 238U had highest activity concentrations near the mine shaft, where...
