Don't waste that heat!

• Installing a heat-recovery system helps the company save on power and gas
• 66 000 kWh of energy and 57 tonnes of CO2 emissions savings per year

The German company Wayand AG produces plastic components for the automotive, commercial vehicle, agricultural and construction machinery industries. The firm produces a wide range of exterior and interior components, from tools to final coating and mounted components.

The company uses compressed air as part of its polyurethane foam manufacturing process. Management saw an opportunity to reuse heat generated by the compressors.

Key benefits

By implementing a heat-recovery system to heat up the buffer storage for its foam tools, Wayand can save € 13 000 on gas and power costs per year. With an investment of € 24 700, the new system is able to pay itself off in less than two years. This measure reduces power consumption by 66 000 kWh and CO2 emissions by 57 tonnes per year.
