“…Furthermore, wet waste affect the yield of synthesis gas adversely and requires more energy to process it, as compared to dry waste. The initial cost in the plasma technology cannot be reduced but operation and maintenance cost can reduced by generating revenue from the by products in the process [3,7,15]. The energy input can be reduced by supplying properly segregated waste.…”

“…Health equipments and kits can be developed for the operator to make it safe for health of the people working on the plant. Technology readiness levels (TRL) assessment examine a technology based on requirement, concept and capabilities on a scale of 0 to 9 with 9 being the most mature technology [3]. The plasma gasification technology is rated moderate to high as it partially achieved the first eight levels of TRL.…”

The age of urbanization has brought exponential growth in population and development along with the huge amount of waste generation. The waste generated is a mix type of waste which is difficult to manage using conventional methods and is ever increasing and changing in nature, blocking essential space that has become an expensive commodity in todays world. Conventional techniques such as combustion, land filling incineration, gasification have been the conventionally preferred method of waste management. The paper proposes a critical assessment of traditional waste to energy (WtE) procedure, starting from basic aspects of the process, performance, environmental assessment parameters to plasma gasification, a alternate WtE. This will assess the socio-aspect of plasma gasification , a more sustainable waste management system with producing a synthetic gas as by-product and slag. Although plasma has high installation and maintance costs, revenue generation form product can make it financially viable. This paper discusses the current limitations of this technology and highlights a few studies that are being conducted around the world that may soon take this concept from technical feasibility to practical reality.

Municipal Solid Waste Characterization and Landfill Gas Generation in Kakia Landfill, Makkah

In many countries, open dumping is considered the simplest, cheapest, and most cost-effective way of managing solid wastes. Thus, in underdeveloped economies, Municipal Solid Wastes (MSW) are openly dumped. Improper waste disposal causes air, water, and soil pollution, impairing soil permeability and blockage of the drainage system. Solid Waste Management (SWM) can be enhanced by operating a well-engineered site with the capacity to reduce, reuse, and recover MSW. Makkah city is one of the holiest cities in the world. It harbors a dozen of holy places. Millions of people across the globe visit the place every year to perform Hajj, Umrah, and tourism. In the present study, MSW characterization and energy recovery from MSW of Makkah was determined. The average composition of solid waste in Makkah city is organic matter (48%), plastics (25%), paper and cardboard (20%), metals (4%), glass (2%), textiles (1%), and wood (1%). In order to evaluate energy recovery potential from solid waste in Kakia open dumpsite landfill, the Gas Generation Model (LandGEM) was used. According to LandGEM results, landfill gas (methane and carbon dioxide) generation potential and capacity were determined. Kakia open dump has a methane potential of 83.52 m3 per ton of waste.

“…Rapid increase in population has resulted in huge demands for energy to for material production. Such thrust for energy and to recover more energy requires technological exploitation of energy resources (Ramos & Rouboa, 2020;Young, 2010). The materials byproducts are related to waste, an inevitable by-product of industrial production.…”

This century is known for exponentially growing population and development but with huge waste production. The waste produced requires land, labour and capital to for treatment and disposal of such huge amount of waste. In India, people throw or consider it as waste after single use so Indian waste can be good resource for recovery of various products. The waste produced is difficult to manage using conventional methods and is ever increasing, blocking essential land that has become an expensive commodity in today's world. This work explores the current practices of the various waste management initiatives and a critical assessment of traditional waste to energy procedure adopted in India. It gives an overview of the various waste management systems in India. Suggestions for improving the health of society, waste management processes, process performance, environmental assessment parameters to plasma gasification,-an alternate waste to energy has been also discussed. Recommendation has been made for the micro-waste plant to solve the waste challenges. Contribution/Originality:The main contribution of the paper is to assess waste management in India and certain waste emerging innovations -Waste to Energy, which are technically applicable and relevant. It also addresses how the use of advanced waste technologies like plasma can be a way of achieving a circular economy as well as less environmental impact. INTRODUCTIONEnergy is one of the foods for technical or economic development of human beings. Rapid increase in population has resulted in huge demands for energy to for material production. Such thrust for energy and to recover more energy requires technological exploitation of energy resources (Ramos & Rouboa, 2020;Young, 2010). The materials byproducts are related to waste, an inevitable by-product of industrial production. The exponentially growing population has increased the waste production to many fold. Although waste is shown to be a non-essential qualitative component of industrial production, the quantitative scope of waste can vary according to the degree of (in)efficiency with which these processes are operated within certain limits. Over the years, the invention of new products, innovations and facilities has altered the quantity and quality of waste. Waste characteristics do not only depend on income, culture and geography but also on a society's economy and situations like disasters that affect that economy (
