Energy Efficiency Loans help Roberts Mart shrink its energy bills by £129,000.

Following expansion, Roberts Mart sold its main premises, a Victorian mill in central Leeds in 2004. As a result, it was able to develop a purpose built factory

The company was also in the process of installing a new eight-colour printing press. This gave it the opportunity to review the way in which it dries the inks on newly printed packaging. The existing gas burners were costing about £6,500 a month to operate. This made it an expensive solution which would also struggle to meet the increased requirements of the new press due to be installed. A Carbon Trust loan of £93,000 enabled Roberts Mart to improve the lighting, while a second loan of £195,000 allowed them to install a regenerative thermal oxidiser (RTO), which uses thermal oil to dry the packaging.
