REPORT

REPORT GREEN EXPERTISE SINCE 1988 Our corporate color is green. For over half a century we have considered it a symbol of our commitment to people and the environment. We began by focusing on improving the environmental safety of total-loss lubrication applications, in which lubricants come into direct contact with the environment. In 1988, for example, we developed the first readily biodegradable chainsaw lubricant based on rapeseed oil. Ten years later, in 1998, this was followed by a whole family of environmentally friendly products for two-wheeled vehicles, forestry, and gardening. By now the share of products we deliver that is readily biodegradable has grown tenfold – a noteworthy success inspiring us at MOTOREX to continue along this path. 12

WHAT DOES BIODEGRADABLE MEAN? Biodegradability refers to the chemical breakdown of substances by natural organisms such as bacteria, yeasts, and fungi in combination with oxygen and light. Mineral oils are only slowly and incompletely degraded by these organisms. Readily biodegradable products, by contrast, are formulated to ensure a complete degradation process. Biodegradability can be measured using various internationally standardized testing processes. THE BIODEGRADATION PROCESS CONTAMINATION PHOTOSYNTHESIS H 2 O + CO 2 + BIOMASS DEGRADATION PERFORMANCE IN % 100% 80% 60% 40% 20% TIME (DAYS) In the OECD* 301 B “storm test” (picture above), biodegradability is determined by measuring how much CO₂ is released over a 28-day period. In full degradation, a readily biodegradable hydraulic fluid completely decomposes into carbon dioxide, water, and biomass. OECD* = Organization for Economic Cooperation and Development ENVIRONMENTAL LABELS IN CIRCULATION Whether it’s lubricants, cleaners, or care products, biodegradable MOTOREX products are proven in practice and are in high demand. These are just some of the environmental labels they’ve earned: OECD 302 Biodegradability not precisely defined, formerly according to CEC-L-33-A-93, now CEC-L-103-12. Ready biodegradability of › 60% over 28 days. Inherent biodegradability of water-soluble, non-volatile filterable substances. German ecolabel Blue Angel (BE) RAL ZU 178 Swedish environmental label May not be exhaustive.
