1 Waste Management is a concerning issue in a country like India with dense population. The exhausted landfills along-with dense population has snowballed the Climate Change impact and it is only fair to say that there is no room for error which negatively impacts the environment and hence bio-diversity.
2 It is vital to establish and promote circular economy to promote sustainable and green waste management. Pyrolysis technology promises to be one such technology which efficiently processes the waste and reforms it into valuable output. The Catalysis model offers the complete reformation of waste on the same day as generated without any need of segregation or drying.
3 Horticulture waste and domestic wet waste constitutes a major percentage of waste generated. The waste being voluminous and wet, requires additional energy and fuel requirements while being transported to the disposal sites. Typically, fresh horticulture waste and wet waste contain approximately 35 percent water during normal seasons and during the rainy season, the water content in this waste can go as high as 65 percent. A bulk of this water evaporates while air drying but still a significant amount of moisture is retained by the bulk of the material. This bulky waste requires space for drying and natural drying may take a few weeks to a few months.
4 There are biological methods which are used to convert waste biomass to bio-compost, bio-gas, bio-methane etc. However, on-site biological processes are not practical as such processes require vast area, sustainable microbial culture, maintenance of bio-culture which requires replacement from time to time, high operating expenses, long time period required for biological reactions to be complete and above all, proper gas cleaning equipment, wet residue disposal means. All these are cumbersome and does not add value to the resource generated from them.
5 On the other hand, Pyrolysis or thermal processing of the waste is a good solution for addressing this problem immediately as the waste is generated. Further, the climate change concerns coupled with the reduction of renewable energy sources, limiting the use of fossil fuels create a new paradigm in the handling of wet biomass and horticulture waste, as these can be a source of abundant renewable energy sources and an excellent source of Hydrogen gas, which will be driver of economies worldwide in the near future.
6 These draft standards are aimed at arriving at futuristic solutions, coupled with guidance on the equipment selection. This draft also provides a pathway towards de-centralized waste management, energy recovery at the location where the waste is generated and discourages transportation of the waste to landfills. Further, it also examines the utilization of the energy abundant resources recovered from the thermal processing of such wastes.
