Solid Waste Management (SWM) system in Bhopal has deteriorated recently to the point that only limited waste collection is undertaken in certain urban areas and disposal is largely to uncontrolled dump sites. In this study, the technical, economical, and environmental aspects of three SWM scenarios were investigated aiming to compare the scenarios and select the most appropriate one for impleme...

Effects of yard waste compost and maize (Zea mays) cultivar on population densities of plant-parasitic nematodes were examined in four experiments in north Florida. In one experiment, eight maize cultivars were evaluated; the other three experiments involved split-plot designs with compost treatments as main plots and maize cultivars as subplots. The three compost treatments used in these exper...

While several EU member states have working compost markets, only about one third of the bio-waste, around 35 Mio tons is used to produce compost, and to some degree, biogas. The major part is still incinerated or landfilled together with other waste. This paper proposes the improvement of existing and the creation of new compost markets based on the integration of biochar and the implementatio...

Exposure to bioaerosols in the occupational environment is associated with a wide range of adverse health effects. Composting is biological decomposition of organic waste material which necessarily leads to proliferation of microorganisms with in the composting substrate, it is potential for these microorganisms to become airborne as the compost is being turned and screened. Exposure to bioaero...

Greenhouse gas (GHG) emissions related to composting of organic waste and the use of compost were assessed from a waste management perspective. The GHG accounting for composting includes use of electricity and fuels, emissions of methane and nitrous oxide from the composting process, and savings obtained by the use of the compost. The GHG account depends on waste type and composition (kitchen o...

Taiwan’s Environmental Protection Administration (EPA) has enacted a food waste recycling policy since 2003 as an alternative of landfill and incineration for the final disposal of municipal solid waste. Recycled food waste is currently seen as a valuable material, especially when appropriate technology is developed. This paper conducts a cost/benefit analysis based on six cases of food waste c...

The effects of adding of a range of organic amendments (biosolids, spent mushroom compost, green waste compost and green waste-derived biochar), at two rates, on some key chemical, physical and microbial properties of bauxite processing sand were studied in a laboratory incubation study. Addition of all amendments tended to decrease bulk density and macroporosity but increase total porosity, av...

The content, behaviour and significance of heavy metals in composted waste materials is important from two potentially conflicting aspects of environmental legislation in terms of: (a) defining end-of-waste criteria and increasing recycling of composted residuals on land and (b) protecting soil quality by preventing contamination. This review examines the effects of heavy metals in compost and ...

In 1993, the Georgia Diagnostic and Classification Prison (located near Jackson, GA) initiated an on-site composting operation to convert food waste into a useable by-product. Each week, inmates compost about 20 tons of food waste, which are mixed with ground cardboard, hay, yard leaves, or wood products. The operation takes place on a 1.2-ha site (3 acres) that drains towards a small, paermial...
