A review on green wastes pyrolysis for energy recovery

Abstract: - Pyrolysis has a long history as a thermo-chemical conversion process to convert biomass to bio-fuels. It has large future potential driven by increased interest in renewable energy sector. Biomass supplies about 14% of the world’s total energy needs. The pyrolysis product such as bio-oil, charcoal and gaseous products have multi-dimensional uses. Bio-oil can be suitable substitute for fuel oil or diesel fuel in many static applications including boilers, furnaces, engines and turbines for electricity generation. Pyrolysis gas and charcoal contains significant thermodynamic properties for heat and power generation in various types of industries. Council green waste, one of the sources of renewable energy, has a positive environmental impact resulting in no net releases of carbon dioxide and very low sulphur content. Pyrolysis process can successfully be applied for converting council green waste into bio-energy. Recent progress in green waste pyrolysis is elaborated and discussed in this paper. The sustainability of bio-fuel generation using pyrolysis, uses and applications of pyrolysis products, environmental impacts of pyrolysis process and recent progress in pyrolysis process modelling and simulation are also presented and discussed in this paper.
