Global megatrends, such as energy and raw materials shortages, urbanization, and population growth are confronting companies and communities with major economic, social, and ecological challenges. Availability and efficient use of energy and resources are crucial to sustainable development and poverty reduction. Sika sees it as its responsibility to minimize the impact on climate change by reducing energy consumption from nonrenewable sources with the positive effect of lowering costs and increasing competitiveness. The Group goal is:

TARGET: 3% less energy consumption per ton and year:

This includes the total energy produced and consumed by all Sika operating companies and units, both industrial and nonindustrial sites. In 2016, this target has been achieved.

IMPLEMENTATION:

Sika consumed 1,779 terajoules in 2016 (previous year: 1,833 terajoules) of energy. Approximately 56% of Sika’s energy requirements were met by electrical power from the local grid. The remaining demand was mainly covered by natural gas and liquid fuels.

Energy consumption per ton sold came to 428 megajoules (previous year: 455 megajoules). Apart from energy-efficiency projects, this significant drop of 5.9% is primarily due to the change in product mix and strong growth in less energy-intensive product technologies.

To maintain the positive trend, the following energy projects have been initiated:

At several Sika production sites (e.g., Zurich, Cerano), the company has improved the adhesive production process. Better energy consumption, time efficiency, and output have been achieved for the drying of fillers. Optimizations based on knowledge of filler characteristics yielded energy savings of around 35%, equivalent to an annual total of 828 gigajoules.

Significant energy savings were also achieved in mortar production at the Guangzhou factory in China by replacing wet-washed sand with dry sand. This substitution will allow 84,000 liters of diesel to be saved each year.
