Environmental and ecological goals go hand in hand

ENERGY MUST BE MANAGED EFFECTIVELY

Global trends, such as long-term energy and raw materials scarcity, increasing urbanization, and population growth confront companies and communities with major economic, social, and ecological challenges. Efficient use of energy and resources is crucial for sustainable development. Sika’s production and distribution activities are less energy intensive than its supplier industries, specifically the chemical industry, but base to a large extent on nonrenewable energy sources. This exposes Sika to price volatilities, supply uncertainties, and increasing regulatory action related to energy consumption like the taxation of CO2 emissions. Therefore, Sika believes that energy efficiency and mitigation of emissions are key success factors of its overall efficiency efforts.  

Efficient Use of Energy

Apart from raw materials, energy is the main resource input for Sika’s operations and thus a relevant cost factor. Therefore, the efficient use of energy is highly important for the company. CO2 emissions are a consequence of fossil fuel consumption, which can be limited by increasing energy efficiency. The CO2 footprint of purchased electricity depends on the power production in each country and cannot be influenced easily. For self-produced electricity, Sika seeks to use low-CO2 energy sources where possible, for example natural gas instead of oil. Sika is committed to reducing the use of nonrenewable energy, thus minimizing negative impacts on climate change, reducing costs, and increasing competitiveness.

OptimizeD product mix to reduce energy and water consumption

HEBEI JIUQIANG BUILDING MATERIALS CO.,LTD, HEBEI JIUQIANG FACTORY, CHINA

The product mix was upgraded due to market pull and sales push from Naphthalene (SNS) to PCE. Further activities encompass increased liquid raw materials volumes instead of powder for PCE production as well as collection and reuse of all boiler and rain water.



Sika avoids air leaks in the production process
yes
Avoiding air leaks in the production process

SIKA YAPI KIMYASALLARI A.S., TURKEY

This project focuses on savings of compressor energy consumption by decreasing the air leaks. Expected savings are at least 7-9% of decrease in compressor energy consumption.

Factory and warehouse relamping
yes

SIKA CORPORATION, PLANT LYNDHURST, USA

The installation of energy efficient interior and exterior lighting led to electricity savings of 979,000 kWh per year. Annual CO2 emissions of 612 tons were avoided. The project was eligible for a New Jersey State incentive to encourage companies to install energy efficient luminaires.

Construction of a solar park
yes
Construction of a solar park

SIKA FRANKE SA, PLANT MARGUERITTES, FRANCE

The installation of 25kWp crystalline solar panels improved the energy efficiency of the Sika factory by providing 31,535 MWh of solar energy annually, corresponding to 9% of the plant’s energy consumption. A contract with the local energy provider (EDF) has been signed to feed surplus energy into the local power grid.

Rice husks as coal replacement
yes
Rice husks as coal replacement

JIANGSU SIKA TMS ADMIXTURES CO. LTD., PLANT NANJING, CHINA

Standard coal was replaced by rice husks to fire powder dryers and to reduce the factory’s CO2 emissions. The replacement of around 1,500 tons of coal annually led to an emission reduction of 3,695 tons CO2 per year. The silica rich ashes are used as raw material in admixtures to substitute silica fume.

DGNB certified Sika training center

SIKA GERMANY GMBH, PLANT STUTTGART, GERMANY

Sika products were used for the construction of a new multi-purpose building according to the challenging German Sustainable Building Council (DGNB) green building requirements. The building has a low operational energy use of 105 kWh/m2 per annum, which is 23% less than required by the German regulations. Together with other partners, Sika was involved in the initial development of a DGNBguideline assisting architects, planners, contractors and owners in the selection and documentation of construction products for DGNB projects.
