Background: Biomedical waste generated from health and health-related activities can be grouped as general waste and hazardous waste. This remains true if and only if there is proper on-site handling, such as the segregation and separation of waste based on the type and nature of the source. Methods: A stratified random sampling design was used to provide representative results for Ethiopia, f...
Introduction: Currently, the conversion of waste from industrial processes to compost through vermicompost has been considered both in terms of health, environmental pollution, and economy. The aim of this study was to investigate the effect of waste process of Halva Ardeh production on vermicompost quality. Materials and Methods: To determine the best combination of cow manure with Halva Arde...
Aluminum enters municipal solid waste MSW landfills from untreated raw curbside trash MSW , industrial waste, and aluminum production wastes variously called dross, baghouse fines, salt cake, and other designations. Aluminum related reactions can arise and become problematic for landfill operations by generating undesirable heat, liquid leachate, and gases, such as hydrogen, hydrogen sulfide, c...
As global industry developed rapidly, the energy demand also rises simultaneously. In the production process, there’s a lot of energy consumed in the process. Formally, the energy used in generating the heat in the production process. In the total energy consumption, 40% of the heat was used in process heat, mechanical work, chemical energy and electricity. The remaining 50% were released into ...
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 ...
With growing environmental and energy concerns, Jatropha plantations are promoted in degraded/waste lands for the biodiesel production. Nutrient rich nonedible deoiled seed cake, a by-product of Jatropha left out after oil extraction was evaluated at the ICRISAT centre at Patancheru, India as an environment friendly source of nutrients for rainy season maize and soybean followed by postrain...
With the passage of the Resource Conservation and Recovery Act RCRA and the subsequent amendments to RCRA e orts to provide tighter controls on the transportation and disposal of hazardous waste have been steadily gaining ground This paper intended as a decision support tool for regional planning incorporates information on the hazardous waste generation treatment capacity and the costs of wast...
