ABSTRACT

 

For a project to qualify as climate change mitigating project, it is necessary that it excludes waste incineration, pelletisation, pyrolysis and gasification systems. Researchers of waste suggest that composting is a better alternative because it saves the amount of energy that incinerating same materials would generate. City compost use can save 50% of normal urea dose and gives 15% higher yield with 30% less water need and less pesticide. Urea production needs both costly naphtha and factory power to produce it. Pesticide usage has become an integral part of modern agriculture system. Accumulation of pesticides in soil or its entry in agricultural runoff is main cause of environmental pollution. Some pesticides are artificially made complex compounds which persist in environment and do not undergo biological transformation (xenobiotics). Microorganisms play an important role in degradation of xenobiotics and owing to this, as nature of domestic biodegradable waste is changing due to use of various pesticides, preservatives and chemicals; requirement is preparation and application of selective bioculture, which can degrade pesticide as well as organic matter. Consequently when bioculture with compost applied to soil it will not only fertilize soil but simultaneously degrade pesticide residues present in farms. In the present study Isolation and characterization of selective microorganisms (mesophiles and thermophiles with pesticide degraders) required for bioculture preparation were carried out. Identification of the pesticide degrader was carried out by 16S rRNA sequencing. After enrichment, its application in composting was tested. Present biological processing proved very effective in stabilization of domestic biodegradable waste containing pesticide residues.
