Abstract:
Human‐induced climate change, mainly through greenhouse gases emission (GGE), is attracting attention worldwide and has become one of the major threats to the environmental sustainability. Utmost is the need to understand the impact of waste management practices on GGE, or countries could incorporate alternative waste management strategies for various organic wastes. Strict regulatory controls limiting waste disposal in landfills and the consequent diversion of biodegradables have resulted in the adoption of sustainable waste management techniques like composting and vermicomposting. However, composting and vermicomposting systems for waste management, especially at large scale have the capacity to emit high levels of greenhouse gases (GHGs). This paper reviews the current available literature pertaining to GGE during composting and vermicomposting of various organic wastes, linking with the fate of carbon (C) and nitrogen (N) during stabilization. Further, the current study provides a comprehensive summary of the emissions and plausible mechanisms and factors responsible for the GGE during both processes. The article also highlights likely mitigation actions relating to process parameters effective in minimizing GGE during composting and vermicomposting of organic wastes.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
