A3.10.4 Control at Source
A3.10.4.1 Air Pollution
Examples of possible air pollution controls for point source control include:
Re-design the product and / or process.
- Eliminate the polluting components.
- E.g. lead free petrol, lead-free solder, VOC free paint.
- Substitute the polluting materials for less polluting materials.
- E.g. replace paints that have a high VOC content with paint containing a reduced VOC content or replace CFC propellants with alternatives.
- Ensure the process is efficient.
- To reduce by-products and wastage.
- E.g. monitor the air flow in combustion activities to ensure the combustion is effective.
- Consider whether chemical or mechanical processes are more suitable.
- Particles generated by chemical processes may be fumes, rather than mechanically generated dust, which is easier to collect.
