Energy intensity is the ratio between the total energy consumed by the company and total tons sold. Energy consumption per ton sold amounted to 363 megajoules (previous year: 424 megajoules).
Sika continued to replace lighting solutions with the latest LED technology. This technology led to substantial energy savings of up to 70% of total lighting electricity consumption at those locations where the technology was implemented. Furthermore, shorter batch times in production led to a higher output from existing production lines, thereby increasing energy efficiency. The replacement of technical equipment focuses on new energy-efficient installations, such as motors, air-conditioning, heating/cooling, and pressurized air systems. Further measures include energy-efficient operation of electric motors with frequency converters, leakage detection and elimination of air losses in pressurized air systems, and energy-efficient cooling of process water using cooling towers and optimized logistics. The modernization of the vehicle fleet also resulted in fuel reductions. Energy audits and participation in energy networks promoted energy awareness throughout the company. A special focus was placed on sand drying. A process optimization guideline was framed in 2019 for global use starting in 2020, which will achieve up to 30% energy savings.
