Company name: Thomas Swan
and Co. Ltd.
Location: Consett, Co. Durham,
Products: Speciality chemicals
for the performance and fine chemicals markets.
Sustainable change: Use of
supercritical carbon dioxide to replace organic
solvents in the manufacturing process.

dioxide remains in its liquid form and can
act as a solvent in many chemical reactions.
This reduces the need for organic solvents
and so leads to less emissions of volatile
organic compounds to the atmosphere.
