Title: Composting and vermicomposting: modified techniques suitable for bio conversion of toxic and complex solid wastes

Abstract:

Composting is a simple process of organic matter decomposition through microbial action. Raw organic substances are laid with partially decomposed animal litter (e.g. cowdung), kept under adequately moist condition to facilitate microbial activity for 5-6 months, and eventually the substrate is mineralized to nutrient rich organic fertilizer. Both aerobic and anaerobic composting systems are in practice, while several workers have claimed to evolve few smart composting processes or reactors such as drum and windrow composting systems. Few workers have also suggested to integrate composting and vermicomposting for higher efficiency. Vermicomposting is a simple aerobic biotechnological process of organic matter decomposition through combined action of earthworms and microorganisms. As such, this earthworm mediated system is far more efficient than conventional composting in regard to particle size and density, nutrient enrichment, time, microbial diversity, and water holding capacity. A wide range of complex industrial and urban wastes can be treated and stabilized through vermicomposting. However, the major benefit of vermicomposting lies in utilizing the metal removal potential of earthworms to remediate waste materials. Importance of earthworm in the remediation of our environment would be evident from two recent publications in Nature Nanotechnology and Nature Communication; where it is emphasized that we have to keep exploring the details of the protection mechanisms in earthworms under stress conditions and utilize this unique creature to remediate and stabilize toxic waste materials. Conventionally, metallothionein (MT) gene and protein are known to be responsible for metal removal as they bind heavy metals and eventually transform them into insoluble or non-toxic forms. Interestingly, our recent study revealed that there may be one or more high molecular weight, non-metallothionein proteins that also efficiently bind cadmium.
