Monitoring Environmental Performance
Monitoring Air Pollution
A great deal of industrial solvents and solvent based coatings give rise to
emissions that are potentially harmful to the environment. Tracking solvent losses
to air and implementing solvent minimisation strategies can help companies make
significant cost savings in reducing waste costs and costs of raw materials.
Tracking and reducing solvent consumption has also means that companies can fulfil
legal obligations under LAPC without needing to install expensive pollution abatement
- When investigating this, the company should compile and maintain a solvent
- Obtaining details from solvent supplier(s) concernin
solvent purchases and advice on how to work out solvent
- Obtaining details of paint purchases, including the
solvent content of paints from paint suppliers. (Appendix.1

- Tracking and recording the amount of waste paint tins /
drums generated over a representative period such as 1 month.
- Measure on a weekly basis the amount of energy used and quantity of
material (solvent and paint) and compare this to work undertaken such
- Components coated.
- Area for painting.
- Amount of spray guns cleaned.
Under LAPC the local council will require information concerning the weight in
kilograms of solvent consumed and disposed of. To convert solvent volumes to
eights their density must be calculated. The table below gives densities of common
solvents. The equation below calculates the weight of solvent from its density and
