A review was conducted on gasification for municipal solid waste and sewage waste. In gasification there are upstream process and downstream process are there. Upstream process consists of size reduction, drying and densification. Downstream process includes gas cleaning and gas utilization process. Gasification process is conversion process of solid and combustible fuel into gas mixtures is known as producer gas. That producer gas will go for downstream process. The main components of the producer gas were carbon monoxide and hydrogen including a small amount of methane and light hydrocarbons. The producer gas or syngas can be used as a biofuel, electricity, biogas etc. It will replace the abundant use of fossil fuels like petrol, diesel, naphtha oil, etc. In gasification process some other by products also obtained they are ash and tar. The generated tar is gravimetric tar, which is total tar. As light tars, benzene (light aromatic tar) was a major light tar. Naphthalene, anthracene, and pyrene (light polycyclic aromatic hydrocarbon tars) were also generated, but in relatively small amounts. Ammonia and hydrogen cyanide (precursor for NOx) were generated from thermal decomposition of tar containing protein and nitrogen in sewage sludge. The ash can used as food products for plants (fertilizer). Utilizing the sewage sludge as an energy source would generate large fossil fuels, neutralize sewage sludge landfills and reduce the risk of developing and spreading the disease due to the presence of harmful substances.
