Precision engineering business cuts annual energy bill by over £14,000 while increasing manufacturing capacity

Growing engineering business takes advantage of an interest-free loan to reduce costs and environmental impact.

DMI Precision Engineering is based in Macmerry in East Lothian. The business has been providing a wide range of engineering services for over 38 years to clients in the oil and gas, aerospace, renewable energy, defence and automotive industries. It employs nine people.

As outlined in the business’s environmental policy, DMI Precision Engineering is committed to reducing its environmental impact and to continually improving its environmental performance as an integral part of business strategy and operations.

While waste and water are well managed at the site, the Managing Director, David Black, contacted Resource Efficient Scotland for advice and support to reduce the company’s energy consumption. In particular, David was interested in upgrading two computer numerically controlled (CNC) machines and a milling machine with a new, more efficient turning centre.

One of our consultants quickly visited the site and carried out an energy saving survey.

The detailed report that was produced following the survey confirmed that a new turning centre would reduce electricity consumption. Specifically, our consultant estimated it would reduce energy use by 34%, cutting annual energy bills by £14,458 and reducing carbon dioxide (CO2) emissions by 33.9 tonnes. In addition, the increased automation of the turning centre would halve manufacturing time and allow more orders to be taken on by the company.

The report also recommended replacing the fluorescent lighting used at the site with more efficient and longer lasting light emitting diode (LED) equivalents. This would achieve an estimated annual cost saving of £1,190 and reduce COemissions by 2.8 tonnes. With an installation cost of approximately £3,000, this opportunity would have a payback of just 2.5 years.

Following our advice, and given the capital investment required for the new turning machine, we provided ongoing support to help DMI Precision Engineering Ltd successfully apply for an interest-free loan from the Scottish Government to fund the investment.

The new turning machine was installed in July 2019 and the business is now considering the lighting upgrade as the next stage in its drive to improve energy efficiency.

 ‘We are committed to reducing our environmental impact and continually improving our environmental performance as an integral part of our business strategy and operating methods. The support and funding we have had from Resource Efficient Scotland have provided a significant boost to achieving these aspirations.’ - David Black, Managing Director.
