Greenhouse Gases Avoided by Using Evonik Products
Evonik markets a variety of products whose use makes a positive contribution to reducing greenhouse gas emissions compared to conventional alternatives. The avoidance of greenhouse gases shown here results from applications for the following four products: “green” tire technology, amino acids for animal nutrition, foam stabilizers for insulating materials, and oil additives for hydraulic fluids.
The amounts stated are avoided over the usage life cycle of the products, based on volume sales of the products manufactured by Evonik in the year given. The method used to compile the data is the WBCSD Avoided Emissions Guidance published in 2017.
The examined applications of selected "beacon products" save the greenhouse gas quantities listed in the table below in comparison to their established alternatives.

GHG-savings by selected Products of Evonik
Compared to conventional car tires, the use of the silica-silane-system and a certain polymer blend (solution styrene butadiene rubber (S-SBR) and butadiene rubber (BR)) – known as green tire technology – can achieve significant fuel savings and improved wet grip without impacting abrasion resistance. The lower fuel consumption results in end-users generating fewer CO2eq emissions.
Animal feed is specifically formulated to meet the physiological and nutritional needs of the animals, and in particular the necessary requirements of essential amino acids. Lack of certain amino acids in animal feed can be compensated either by adding a higher percentage of protein-rich feed components such as oil seed, or by fortifying the feed with essential amino acids produced by Evonik for this purpose. Supplementing animal feed with essential amino acids can save significant amounts of feed raw materials, resulting in the freeing up of agricultural land and a corresponding reduction in CO2eq emissions. Furthermore, feed supplementation with these essential amino acids reduces emissions of both nitrogen and greenhouse gases resulting from feeding and excretion, and offers credits for the use of natural manure.
Evonik develops additives, specifically foam stabilizers (TEGOSTAB®), which are very important in foam production and for optimizing foam properties. These polyurethane (PU)-based foams are used, for example, in building insulation or for insulating electrical appliances such as refrigerators. The improvement of insulation properties reduces energy consumption and thus helps reduce greenhouse gas emissions.
Mobile construction machines consume the bulk of their required energy in their hydraulic units. The use of DYNAVIS® technology can achieve significant fuel savings and higher productivity compared with conventional (monograde) hydraulic oil. Lower fuel consumption means that end users generate fewer greenhouse gases (CO2eq), especially carbon dioxide.
