Waste disposal is one of the pressing problems.Millions of tons of municipal solid waste, hazardous/industrial wastes and agricultural wastes are handled daily throughout municipal areas. Each municipality confronts great challenges in disposing of its wastes in an efficient, cost effective and environmentally safe manner.Landfills in metropolitan areas are becoming full, and new ones are more ...

Waste generation has increased considerably worldwide in the last few decades. Solid wastes encompass the heterogeneous mass of throwaways from the urban community as well as the homogeneous accumulations of agricultural, industrial and mineral wastes. Waste generated from biomedical activities represents a real problem of living nature and human world. A proper waste management system should b...

This paper investigates the feasibility of processing the organic fraction of the municipal solid waste from the Winchester, Southampton, Eastleigh and wider areas (population ~450,000) using anaerobic digestion. Commercial and agricultural organic waste is also considered. Data for feedstock location, volumes and type is collated from many information sources. A model is used to estimate the e...

Food waste has a significant detrimental economic, environmental and social impact. Recent efforts in HCI research have examined ways of influencing surplus food waste management. In this paper, we conduct a research survey to investigate and compare the effectiveness of existing approaches in food waste management throughout its lifecycle from agricultural production, post-harvest handling and...

A lipase producing bacterium, Bacillus cereus MSU AS was isolated from the gut of a marine fish Sardinella longiceps. In total, seven agricultural waste substrates (coconut oil cake, neem oil cake, onion skin waste, wheat bran, jack fruit waste, banana skin peels and pomegranate skin peel) were selected for solid state production of lipase by B. cereus MSU AS. Among the tested substrates, onion...

Rice husk (RH) is one the largest agricultural waste products worldwide, and rice is one of the crops that use the most pesticides. Among these, organophosphates have been of increasing concern due to their high toxicity. Herein, we report the functionalization of RH with imidazole groups (RHIMZ) to obtain sustainable catalysts from waste for organophosphate degradation. The waste-derived catal...

Economic growth inevitably influences the food chain. Growing demand with changes in lifestyle and health consciousness encourage use of packaged and pre-prepared foods. The needs of environmental protection from waste generated are largely overlooked, and a lack of knowledge about the impact on the environment and its health effects constitute food security/safety problems. Food production and...

The waste water showed high values of total solid (TS), hardness and chloride with slightly alkaline pH along with high concentrations of Cr (2.03 mg l(-1)), Ni (1.59 mg l(-1)) and Zn (0.46 mg l(-1)). The concentration of Cu (0.21 mg l(-1)) and Zn in industrial waste water was low than Ni and Cr. The diluted (25 and 50%), undiluted (100%) waste water was used to irrigate the lettuce plants grow...
