摘要

近年来,人们对从旧垃圾场回收资源的兴趣日益浓厚,这大大加快了垃圾填埋场采矿(LFM)的采用。本研究的重点是使用基于地层的方法评估从各种遗留垃圾场回收的材料的质量。该方法包括废物特征、元素分析、物理化学特征、重金属分析和相关性分析,以评估从所有三层收集的固体废物样本的潜力。结果揭示了废物组成的有趣模式,随着深度的增加,土壤类分数增加,一次性塑料的百分比在所有层中几乎相同。元素分析揭示了不同层间氮、碳、氢和硫含量的变化,显示了遗产的异质性。前两层的碳百分比变化不大,表明以垃圾衍生燃料的形式用作燃料的潜力很大。在第3层观察到明显的变化,表明它最适合垃圾填埋气体收集。其他因素也出现了类似的趋势。富氮物质的存在表明有可能产生氨,而富氢物质则表明有可能产生氢气。富含硫的废物有望产生二氧化硫。进行相关分析,使资源回收率最大化,同时使环境风险最小化。

Strata-based approach for determination of resource recovery potential from legacy waste dumpsite in India.

The growing interest in recovering resources from old dumpsites has greatly accelerated the adoption of landfill mining (LFM) in recent years. This study focuses on assessing the quality of materials recovered from diverse legacy waste dumpsites using a strata-based approach. The method involved waste characterization, elemental analysis, physico-chemical characterization, heavy metals analysis and correlation analysis to assess the potential of solid waste samples collected from all three layers. Results revealed intriguing patterns in waste composition, with an increase in soil like fractions with depth and percentage of single-use plastic was almost same in all layers. Elemental analysis revealed variations in nitrogen, carbon, hydrogen and sulphur content across different layers, showcasing the heterogeneity of legacy. There was a small variation in the percentage of carbon in the first two layers, indicating high potential for use as fuel in the form of refuse-derived fuels. Significant changes were observed in layer 3, indicating it is best suited for landfill gas collection. Similar trends were observed for other elements. The presence of nitrogen-rich content indicates the potential for ammonia production, whereas hydrogen-rich materials suggest the possibility of generating hydrogen gas. Sulphur-rich waste holds promise for contributing to sulphur dioxide production. Correlation analysis was performed to maximize resource recovery while minimizing environmental risks.
