Landfill sites are becoming over crowded and expensive for waste disposal, efforts are made to minimize the quantities of materials that are delivered to landfills. The threat due to leaching of non-biodegradable materials like waste plastics, scrap tyres. e-waste may contaminate the soil and ground water. If the production of waste cannot be prevented, then it is attractive to create an altern...

Biomedical waste is any kind of either solid or liquid containing infectious, potentially infectiousmaterials medical, laboratory research origin from activities such as diagnosis, prevention & treatmentof diseases. Bio-medical has a higher potential infection and injury to the healthcare worker, patientand surrounding community. It consists human anatomical waste, animal microbiology &biotechn...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

Construction and Demolition (C&D) wastes contribute the highest percentage of wastes worldwide (75%). Furthermore, ceramic materials contribute the highest percentage of wastes within the C&D wastes (54%). The current option for disposal of ceramic wastes is landfill. This is due to unavailability of standards, avoidance of risk, lack of knowledge and experience in using ceramic wastes in const...

BACKGROUND Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES To characterize types and evaluate waste disposal techniques employed in th...

Disasters occur due to both the natural and man-made activities. Hazards and Disasters are categorized into four groups, viz., Natural events, Technological events, Man-made events and Region-wise events. The adverse impacts caused due to the indiscriminate disposal of Hazardous Wastes (HWs) come under the category of Environmental Disasters. Hazardous Waste Management (HWM) is a very important...

Sharp medical waste is infectious and hazardous because of their high potential diseases transmission injury. It poses serious threats to environmental health. A cross sectional study was done assess the level knowledge practices health workers on safe disposal sharp wastes. This in Pirojpur Sadar Hospital, Nazirpur Upazilla Health Complex Zia Nagar Complex. Sample size 200 Workers. Semi-struct...

Industrial biotechnology processes have recently been exploited for an economic utilization of wastes to produce value added products. Of which, fish waste is one of the rich sources of proteins that can be utilized as low cost substrates for microbial enzyme production. Fish heads, tails, fins, viscera and the chitinous materials make up the wastes from fish industries. Processing these wastes...
