Abstract

Indian Railways (IR) is the third largest in the world and an economic transportation mode in India. A recent report by the Central Pollution Control Board, Government of India revealed that most of the IR stations were unable to comply with the norms of solid waste management especially on treatment of plastic waste. Hence, this study is aimed to explore potential plastic waste resources/generation across Indian Railway Units (IRUs) and to recommend eco-smart energy solutions to improve plastic waste management at IRUs. Significant problems related to collection, segregation, and treatment of railway mixed plastic waste were addressed. Recent initiatives by IR to eradicate the plastic pollution in IRUs were highlighted in the study. Eco-smart solutions such as financial rewarding system, concession in railway ticket price, priority reservation during booking of railway tickets, converting the unsegregated waste into valuable products of railway platform tiles, pavements, and bricks were recommended. Finally, the study provides a comprehensive perspective of plastic waste to energy conversion in terms of plasto-oil, plasto-char, and plasto-gas products.

印度铁路的生态智能塑料废物转化为能源解决方案:现状、挑战和未来足迹

印度铁路是世界第三大铁路，也是印度的经济运输方式。印度政府中央污染控制委员会最近的一份报告显示，大多数IR站无法遵守固体废物管理规范，特别是在处理塑料废物方面。因此，本研究旨在探索印度铁路单位(iru)潜在的塑料废物资源/产生，并建议生态智能能源解决方案，以改善iru的塑料废物管理。解决了铁路混合塑料垃圾收集、分类和处理的重大问题。该研究强调了IR最近为消除病毒中的塑料污染而采取的措施。建议采用经济奖励制度、铁路票价优惠、火车票预订时优先预订、将未分类的废物转化为铁路月台砖、人行道和砖等有价值的产品等生态智能解决方案。最后，本研究从塑料-油、塑料-焦和塑料-气产品三个方面对塑料废物进行了全面的能源转化。图形抽象
