Abstract This chapter highlighted conventional and advanced waste treatment technologies in details, for sustainable wastes management. The chapter also reviewed Supercritical Water Biomass Gasification (SCWBG) from Municipal Solid Waste (MSW) at the temperature and pressure of 700 C and 350 bar, respectively. The findings show that gasification of organics from MSW using Supercritical Water Gasification (SCWG) technology can be a potential solution to the increasing biodegradables in the municipal solid wastes. However, with the ability of the system to allow the complete gasification of biomass below the working temperatures, this makes it even more attractive technology for sustainable wastes to wealth. With the wide varieties of sustainable fuels and chemicals that can be generated in the process, Supercritical Water Gasification (SCWG) technology can be a candid sustainable and economical energy solution for power generation and transport renewable fuel for automobiles (methane and hydrogen gas).

1 Introduction The global energy sector is making efforts in turning waste to wealth especially in consideration of the global energy security and its allusion to global warming and climate change. In recent years, the municipal solid waste disposed of in most the developed, developing and underdeveloped countries has become a major challenge to the environment [1–3]. The global environmental problems related to municipal solid wastes (MSW) make it necessary for the discovery of the methods that can be used in converting waste
