Reducing energy intensity
Gränges works to achieve continuous energy efficiency improvements. The company carries out regular energy audits and considers the best available technology for new investments and refurbishments. Energy efficiency measures are primarily linked to improved metal yield, thermal processes and recovery of waste heat. Important energy sources are natural gas, electricity, and liquefied petroleum gas and the main energy consumption occurs in the re-melting and casting processes. In 2020, Gränges conducted regional energy intensity opportunity assessments and updated its 2025 activity plans.
Promoting renewable energy
In the Finspång site, Gränges uses electricity in induction re-melters and liquefied petroleum gas in combustion melters. Since 2020, the operations in Finspång source specified electricity from 100 per cent (41) hydro power, sourced through the deregulated energy market in Sweden. In the production facilities in Shanghai and Americas, operations primarily use natural gas, and electricity is sourced from regulated energy markets which currently are mainly based on nuclear and non-renewable energy.
In 2020, Gränges conducted regional opportunity assessments and updated its 2025 activity plans to achieve a higher share of renewable energy.
