Capital Valley Plastics - 0% business loan

Capital Valley Plastics manufacture polythene membranes for the construction and packaging industries, using blown and cast extrusion lines. With the help of a Carbon Trust 0% APR Business Loan, they increased their production line efficiency and cut their carbon emissions.

Technical approach

Capital Valley use extrusion machines to produce blown plastic film. The plastic pellet is fed into the barrel of the machine, where it is heated until molten, and then forced at pressure through the barrel by a screw, which is powered by a 300Kw motor.

Capital Valley worked with the Carbon Trust to review every stage of their processes. Flaws were identified which were causing their machines to run inefficiently, operating at a high output and taking longer to produce a set amount. It was identified that the screw and barrel could be re-engineered to increase their efficiency and therefore decrease the power and CO2 used to produce the same amount.

Their machines ran 24 hours a day, 5 days a week. Before re-engineering, one of the machines produced 315Kg per hour. After the upgrade, it now produces 400Kg per hour. This has enabled Capital Valley to produce the same amount in one day less, using less energy and less CO2.

Implementation of the project required careful planning, given the need to put the production line out of action for periods of time. One advantage of the down-time has been the ability for Capital Valley to re-engineer parts of their processes. This will increase their output capability longer term, enabling them to manufacture more goods and bring lead times down for their customers.

In a time when banks seem unwilling to lend to SMEs, the Carbon Trust proved an enthusiastic and knowledgeable partner to help us achieve our environmental targets.
