Waste incineration involves the application of combustion processes under controlled conditions to convert waste materials to inert mineral ash and gases. The three Ts of combustion (temperature, turbulence, and residence time) must be present along with sufficient oxygen for the reaction to occur:
- The burning mixture (air, wastes, and fuel) must be raised to a sufficient temperature to destroy all organic components. The combustion airflow is reduced to the minimum level needed to provide the oxygen for the support fuel (gas, oil, or coal) and the combustible wastes without forming high levels of CO and unburned hydrocarbons. This will raise the temperature to the level needed for good_combustion.
- Turbulence refers to the constant mixing of fuel, waste, and oxygen.
- Residence time is the time of exposure to combustion_temperatures.
- Oxygen must be available in the combustion zone.
The following are all methods of initiating source reduction:
- Do not purchase as much, or reduce use.
- Purchase products with reduced toxics.
- Purchase environmentally preferred products.
- Buy multiple use products.
- Purchase products with less packaging.
- Buy concentrated products.
- Purchase products in bulk or larger sizes.
- Do not replace for style.
- Purchase more durable products for combustion.
- Maintain properly and repair instead of replace.
- Purchase reusable products and then reuse or donate to charity.
- Purchase more efficient products, or use products more efficiently.
