Waste-to-Energy Recovery Principles

Waste-to-Energy Recovery Principles

Energy recovery is one of many waste-to-energy technologies, others including gasification, pyrolysis of combustible materials, and anaerobic digestion.

 

Incineration and low-temperature magnetic pyrolysis both extract energy from waste, but their principles are not similar. Incineration produces high-temperature thermal energy, while the main energy product of low-temperature magnetic pyrolysis is usually combustible gas. Incineration and low-temperature magnetic pyrolysis can also be carried out without energy and material recovery.

 

High-temperature incinerators, due to insufficient gas purification and combustion process control, often endanger the health of factory workers and the local environment. In some countries, experts and local communities still express concerns about the environmental impact of incinerators.

 

Low-temperature magnetic pyrolysis chimneys mainly produce carbon monoxide, hydrogen, and water vapor, eliminating the need for complex gas purification equipment. This is because they produce very little dioxins, do not increase heavy metals, and generate only rare fly ash.
