This study examined macro-nutrient content of solid waste compost to determine the potential of the compost for soil fertility amelioration in Ghana. Heavy metal concentrations in the compost were also examined to assess the potential health implication of compost application in urban and peri-urban agriculture. It was observed that the overall NPK concentration was low in the different compost...

The paper summarises a literature review into waste management practices across Africa as part of a study to assess methods to reduce carbon emissions. Research shows that the average organic content for urban Municipal Solid Waste in Africa is around 56% and its degradation is a major contributor to greenhouse gas emissions. The paper concludes that the most practical and economic way to manag...

We studied the effects of applying different composts (urban organic waste, green waste, manure and sewage sludge), mineral fertilizer and compost plus mineral fertilizer on chemical, biological and soil microbiological parameters over a 12-year period. The organic C and total N levels in soils were increased by all compost and compost + N treatments. Microbial biomass C was significantly (P £ ...

the exponential growth of urbanization leads to increase in severity of environmental problemsespecially assonated with disposal of solid waste. with considering the increasing rate of solid waste generation in urban area, the problem of availability of space required to dispose it off is become a concern for planners and administrators of urban local bodies (ulb). in order to cope up with the ...

Utilisation of Municipal Solid Waste is important to curb the ever rising demand of scarce land for its disposal. Changing life style patterns, particularly in urban areas, has led to increase in generation of MSW. Municipal solid waste from Indian cities estimated to have 40% 60% organic matter, which could be recycled as compost. The most suitable way to recycle it with low investment is aero...

The environmental impacts of recycling, mechanical biological treatments (MBT) and waste-to-energy incineration, the main management strategies to respond to the increasing production of post-consumer materials are reviewed and compared. Several studies carried out according to life-cycle assessment (LCA) confirm that the lowest environmental impact, on a global scale, is obtained by recycling ...

Vegetable waste usually contains high levels of organic matter, moisture and nutrients that make the waste unsuitable for disposal in municipal landfills. Composting of vegetable waste is in practice by many urban local bodies, and therefore, it was composted along with cow dung and sawdust in a 550-L batch scale rotary drum composter. Four different trials of varying waste combinations of vege...

Field experiment was conducted in 2008 at the Research Field of Agricultural College of Shiraz University, Shiraz, Iran to investigate the effects of urban waste compost (UWC), manure and chemical fertilizer on the initial growth of corn (Zea mays). Experimental design was split plot factorial with three replications. Main plots were assigned to nitrogen (N) fertilizer (0 and 200 kg N ha-1), an...
