Construction firm Tarmac has highlighted its success of working with employees to reduce energy usage as part of its sustainability efforts, having cut emissions by 27 per cent since 1990.
The firm’s 2015 Sustainability Report details a range of measures taken to improve efficiency and reduce the environmental impact of operations.
Among the company’s most successful initiatives are its ‘Ultimate Manufacturing-Optimise’ and ‘Re-Energise’ programmes, which encourage employees to think about operating more efficiently and identifying opportunities to improve their sites and offices.
“The best way to get energy efficiency improvements off the ground is to get everyone involved”, the report reads.
By introducing a ‘Re-energise Calendar’, employees were provided with monthly energy efficiency ideas and opportunities to consider and address at their site, covering areas such as improving pumping efficiency, fuel management systems and reducing electricity base load.
Meanwhile, employees helped to identify over 1,100 improvement opportunities during a 48-week ‘Optimise’ programme across 80 sites, which are being progressed through an improvement log process.
For example, a team of 80 employees at one site managed to reduce gas and electricity consumption by more than 25 per cent during 2015 through measures such as improving boiler efficiency, replacing lights with high efficiency LEDs and optimising compressed air systems.
The programme has been rolled out to further sites in 2016, with “multi-million pound savings” expected to be achieved through reduced waste and energy use.
Training has also been provided to help increase employees’ skills on process operations to ensure they are operating in the most efficient way.
To support these efforts, Tarmac has rolled out an operational performance management system (OPMS) across its sites to capture continuous improvement-related data, using kWh and litres of fuel per tonne of output as performance indicators. The data gathered is used to help share best practice across sites.
In total, Tarmac’s efforts have reduced its emissions by 27 per cent from a 1990 baseline, and put it on target to achieve a 37 per cent reduction by 2020.
Martin Riley and Oliver Mahon, senior vice presidents at the company, said that their sustainability strategy encompasses both “environmental, social and economic performance” and “how we build a business that people want to work for.”
“Sustainability remains a cornerstone of managing the long-term future of our business and plays a fundamental role in shaping our growth strategy”, they added.
