Sika's Innovative Heating Solution Reduces Energy Use by 70 Percent and Lowers Carbon Emissions by 60 Percent at New China Chemical Park
Keeping energy and operational costs low while minimizing carbon emissions is key to Sika's sustainable decarbonization strategy. Sika developped an engineering solution to decarbonize the process and space heating at the upcoming Chemical Park China (Zhejiang).
Early involvement in the design phase made it possible to avoid using steam from the local district heating system, which relies on coal-generated steam from a nearby power plant, leading to high indirect emissions (Scope 2 GHG) for the new facility. Instead, an innovative heating solution was designed, featuring a system that integrates both air-water and water-water heat pumps.
This approach focuses on recovering waste heat from multiple sources, incorporates a hot water thermal storage unit to handle heat demand fluctuations and peak loads, and ensures reliable heating under all conditions. The design reduces energy consumption for process and space heating by 70 percent and lowers carbon emissions by 60 percent, equivalent.For the new Chemical Park China, this translates to annual savings of over 1 GWh and more than 400 tons of carbon dioxide emissions, with the potential to reach up to 600 tons if green electricity is used.
"As part of our commitment to sustainability and reducing greenhouse gas emissions, we are excited to adopt an innovative technological solution for our plant operations. We are proud to proactively decarbonize Sika's operations from the outset of the plant's lifecycle. This initiative not only helps reduce greenhouse gas emissions but also aligns with our sustainability targets, reinforcing our commitment to environmental stewardship."
