The proximity of Inchinnan and other West of Scotland sites makes commuting practical for many residents.

Trends in the Chemical Industry

Sustainability is transforming the chemical industry. Companies are developing bio-based feedstocks, reducing emissions and improving energy efficiency. Industrial biotechnology, which uses biological processes to make chemicals, is a fast-growing area where Scotland has particular strengths. Carbon capture and hydrogen are being explored to decarbonise production, while pharmaceutical manufacturing continues to grow with demand for advanced medicines and biologics.

The circular economy is also gaining momentum, with businesses finding ways to recycle plastics, recover materials and turn waste into valuable products.

Safety and Regulation

Chemical manufacturing is highly regulated to protect workers, communities and the environment. Companies must comply with health and safety legislation, environmental permits from the Scottish Environment Protection Agency and chemical regulations covering registration and safe handling. Strong safety cultures and transparent community engagement are hallmarks of responsible chemical companies.
