Waste Energy Recovery Measures, Including Waste Power Generation

Gasification of plastic waste as waste-to-energy or waste-to-syngas recovery route

The disposal of plastic solid waste (PSW) has become a major worldwide environmental problem. New sustainable processes have emerged, i.e. either advanced mechanical recycling of PSW as virgin or second grade plastic feedstock, or thermal treatments to recycle the waste as virgin monomer, as synthetic fuel gas, or as heat source (incineration with energy recovery). These processes avoid land fi...

Waste Management Issues, including Recovery, and Sustainable Food and Agriculture

The use of different agricultural or industrial wastes is an important component of sustainable agriculture in order to close nutrient cycles on a global, regional and local scale. Farmyard manure or slurry are established as fertilizers in agricultural or horticultural production and substitute mineral fertilizers. Due to the lower nutrient use efficiency compared with mineral fertilizers, esp...

Material resources, energy, and nutrient recovery from waste: are waste refineries the solution for the future?

Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incinerat...

Electrical and Electronic Plastics Waste Co-Combustion with Municipal Solid Waste for Energy Recovery

Economics of Removal of Coal Moisture in Thermal Power Generation with Waste Heat Recovery

The techno-economic aspects of coal drying with cost effective waste heat recovery mechanism is one of the challenging issues faced while using lignite or high ash brown coal for direct combustion in coal fired thermal power plant. Coal being hygroscopic in nature, re-adsorbs considerable moisture even after conventional drying post wet coal washing condition affecting boiler performance. Parti...
