Vermicomposting is a mesophilic biooxidation and stabilization process of organic materials that involves the joint action of earthworm and microorganism. An experiment was conducted to prepare vermicompost using partially decomposed organic waste such as MSW, fruit waste, vegetable waste and yard...
Environmental data analysis and modelling
The concentration of ozone in the earth atmosphere has been steadily falling by 4% in the total amount since late 1970. With the widespread usage of modern industry chlorofluorocarbons, the rate at which ozone content decreases is escalating, resulting in an ozone hole. The depletion permits harmful...
