Performance assessment of plasma gasification for waste to energy conversion: A methodology for thermodynamic analysis

In recent years, attention has focused on exergy analysis, a type of thermodynamic analysis which is an important tool for the efficiency assessment and the processes optimization when dealing with energy conversion and, particularly, thermochemical processes such as gasification. Thus, this chapter aims to introduce the fundamental concepts of energy and exergy and describe the energy and exergy evaluation tools, elucidating its importance for calculations applied to gasification processes. A case study was performed to show the proposal of energy and exergy analysis. Therefore, a single global gasification chemical reaction was used to represent the gasification process. This analysis can provide a tool to assess and develop models, simulations, calculations, and to optimize real gasification processes. Information and experiences covered in this chapter help to be put into perspective the technology, research and overcoming of challenges.

Compost Leachate

Big Rubbish has always been an issue to most major cities in Indonesia. The need to solve, handling and reducing tons of waste has become very urgent. One of the solution is People’s Electricity Program. The Idea is by converting domestic waste to energy in efficient, affordable and eco-friendly ways. The research started in Pondok Kopi RW 10, East Jakarta, converting domestic waste using bio-digester method, and thus experiments succeed turn the trash to compost leachate that can be use as fertilizer as well as forage ingredient. In this article, authors will focus on the detail of An-aerobic Digester known also as bio-digester method which is an alternative technology in The People’s Electricity Program to manage waste, converting it as energy. While researching and developing for People’s Electricity Program, The idea to create briquettes from waste came up. This waste-briquettes is being tested and checked in laboratory where its eventually having calorie level closed to coal’s calorie level. By using the bio-digester method on People’s Electricity Program, the waste-to-energy conversion can be built any where and become a solution to waste management, reducing the amount of junk while giving value provide an energy source for community.
