A Study on Waste Management at Langadiyawas Landfill, Jaipur: Feasibility of Plasma Arc Gasification

The landfill situation in Langadiyawas, located in Jaipur, Rajasthan, faces issues relating to an excess of municipal solid waste (MSW) generation, improper dumping, and environmental damage. Its excess waste breakdown has resulted in waste production of 500 tonnes a day which leads to the Langadiyawas dump site as the primary disposal site. In turn, the overcapacity of landfills has resulted in groundwater pollution, air quality deterioration, and methane gas release. An incineration facility to convert waste to energy (WTE) is planned to be built by the Jaipur Municipal Corporation (JMC) on site, however, Plasma Arc Gasification (PAG) proves to be a cleaner and more efficient source. The goal of this study is to assess the viability of PAG implemented in Langadiyawas, focusing on the ineffectiveness of the current waste management systems and establishing a test case for the city. This research investigates the use of Plasma Arc Gasification (PAG) as an alternative strategy for effective waste management for Jaipur. With the capacity to destroy municipal solid waste (MSW) with the most extreme temperatures available (3000-10000ºC), PAG also creates syngas (composed out of hydrogen and carbon monoxide) and vitified slag while generating clean energy. In comparison to traditional incineration, PAG yields much lower emissions of pollutants such as carbon dioxide, dioxins, furans, and guarantees the destruction of almost all waste material.
