Combustion

Combustion

Combustion involves burning waste material in a high temperature (1000-1100C), oxygen rich environment.

The process converts all carbon and hydrogen in the waste into carbon dioxide and water (referred to as flue gas) which can be used to generate electricity and heat.

Heat generated by the combustion process can be used for community or industrial heating/cooling where opportunities exist.

The combustion process takes place in sealed vessels and within an enclosed building.

Advantages of combustion

Reduces greenhouse gas emissions and waste going to landfill
Commercially proven technology
Produces a marketable product (energy and heat)
Low risk of water pollution
Low risk of odours
High recovery rate of resources
Minimal risk of health consequences

Disadvantages of combustion

High capital and operating cost due to regulatory standards
Plant requires a large land area
