Abs：High temperature pyrolysis and gasification process compared to incineration, can generate a wider range of process by-products. The traditional incineration process can only generate electricity, whereas pyrolysis and gasification process is able to produce different byproducts, including biochar, bio-fuel and syngas, according to different industrial needs to produce a variety of re-use value. Pyrolysis and gasification processes can help achieve the goal of renewable energy, by reducing emissions and curbing global warming and in line with the initiative of the Kyoto Protocol. While the traditional waste incineration energy is more likely used for steam boiler power generation, resulting in lower energy efficiency.
Waste incineration for MSW handling and power generation as a traditional treatment process can make waste of resources, but also induced many concerns especially during operation , the emissions of dioxin and other toxic gases, and waste conversion efficiency is low. Unlike waste incineration that requires aerobic contact, pyrolysis and gasification processes treat waste in anoxic or anaerobic environment.
High-temperature gasification of bio-solid can decompose organic matter in waste, and the waste is heated in an environment with very low oxygen content (480-1650 ° C). At the same time, the process will produce heat with complex components, hot gaseous mixture are removed, called syngas (hydrogen and carbon monoxide-based). The synthesis gas can be used to generate energy and drive the operation of steam turbines or gas turbines. High temperature gasification only produce very little biochar.
High temperature pyrolysis means that in an oxygen-free environment, the waste is degraded by high temperature (200-760 ° C) and produce biochar, bio-fuel and syngas. Especially biochar (Biochar), can be applied to a number of application, including sewage, air purification, soil improvement and so on.

Pyrolysis and gasification facilities can provide modules with different throughput levels that can be tailored to small scale (30,000 tonnes / year) or large scale (150,000-500,000 tonnes / year) depending on the size of the community and the amount of waste generated. The operation scale can upgrade by increasing the number of modules to improve the processing capacity according to the requirements.
