In India non-hazardous industrial waste is generated at a staggering rate of about 30 million metric tonnes/year; considering the major generators (excluding power plant and mining industry waste) as per Ministry of Housing and Urban Affairs, Government of India (GoI), thus disposing of them is a challenge. The industrial waste generated from fast-moving consumer goods (FMCG) trade rejects and expired product is also enormous (although largely remains unaccounted) and needs to be disposed of by the producer as per the guidelines of the Ministry of Environment, Forests and Climate Change, GoI. Co-processing of this industrial trade rejects in cement plant can be a prominent solution as it reduces the disposal problem of the solid waste stream and provides an alternative methodology for complete thermal and material recovery of the waste with no by-products. Co-processing further reduces the use of conventional resources by utilizing the waste as an alternative fuel and raw materials. The study thus analyzes a co-processing trial of a month in a cement plant in the southern part of India and based on the obtained data, the environmental and operational sustainability was studied. The economic benefit obtainable was also analyzed based on the achieved substitution benefit. Parameters such as emission and quality of the final product were gauged. The leaching behavior of the final product was also analyzed. Thus, the findings will help in reducing the carbon footprints of the industrial wastes, specifically the FMCG trade waste, and will show the sustainability of co-processing waste in Indian cement plants.
在印度，非危险工业废物的年产生量惊人，约为 3000 万吨；根据印度住房和城市事务部（Ministry of Housing and Urban Affairs）的数据，主要的工业废物产生者（不包括电厂和采矿业废物），因此处理这些废物是一项挑战。快速消费品（FMCG）贸易废品和过期产品产生的工业废物也非常巨大（尽管在很大程度上未被统计），需要根据印度环境、森林和气候变化部（Ministry of Environment, Forests and Climate Change）的指导方针，由生产商进行处理。在水泥厂中协同处理这些工业贸易废品是一个突出的解决方案，因为它可以减少固体废物的处理问题，并为废物的完全热回收和材料回收提供替代方法，而没有副产品。协同处理还通过将废物用作替代燃料和原材料来减少对传统资源的使用。因此，本研究分析了印度南部一家水泥厂进行的为期一个月的协同处理试验，并根据获得的数据，研究了环境和运营的可持续性。还根据实现的替代效益分析了可获得的经济效益。评估了排放和最终产品质量等参数。还分析了最终产品的浸出行为。因此，这些发现将有助于减少工业废物的碳足迹，特别是 FMCG 贸易废物，并展示印度水泥厂协同处理废物的可持续性。
