Quick Glance at MSW-to-Energy Systems

waste-dump

Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world. Waste-to-Energy (WTE) or Energy-from-Waste (EfW) is the use of modern combustion and biochemical technologies to recover energy, usually in the form of electricity and steam, from urban […]

The Promise of Biochar and Bio Oil

biomass pyrolysis

Biomass pyrolysis transforms organic material such as agricultural residues and wood chips into three main components: syngas, bio-oil and biochar (which contain about 60 per cent of the carbon contained in the biomass. Biomass pyrolysis process can be used to sequester the carbon and  remove circulating carbon dioxide from the atmosphere and stores it in virtually […]

Pathways for Waste-to-Energy Conversion

WTE systems

The conversion of waste-to-energy can proceed along three main pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic […]

Woody Biomass as a Source of Renewable Energy

wood

A wide range of woody biomass resources are available for conversion into renewable energy in natural forests, rural areas and cities. There are many ways to generate electricity from woody biomass using thermochemical pathway, including directly-fired or conventional steam approach, co-firing, pyrolysis and gasification. Direct Firing Most of the woody biomass-to-energy plants use direct-fired system […]

What You Need to Know About Waste-to-Energy Processes?

WTE systems

A wide variety of waste-to-energy processes are available for realizing the potential of waste as an energy source, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts of municipal and industrial waste. These methods can be broadly divided into thermal and biological processes. Some […]

Recycling of Waste Tyres

Scrap Tires

Management of waste tyres is a challenging task because tyres have a long life and are non-biodegradable. The traditional method of waste tyres management have been stockpiling or illegally dumping or landfilling, all of which are short-term solution. Stockpiled tyres provide perfect breeding grounds for mosquitoes, vermin and snakes. Accidental fires caused in tyre dumps […]
