The extensive selection of bioderived esters includes low-viscosity monoesters, medium-viscosity polyol esters and high-viscosity complex esters. A number of products are also registered as LuSC and/or HX-1 food-grade components.

According to Doug Placek, global director of the Lubricants division, “This diverse range of products enables the formulation of renewable lubricants for industrial, automotive and marine applications. We are pleased to provide these options to our customers whose product lines include high-performance sustainable technology. We are particularly excited to announce this on Earth Day 2021.”

The USDA BioPreferred Program was established to increase the use of biologically derived products and renewable agricultural resources, reduce the consumption of petroleum and contribute to reducing adverse environmental and health impacts.

Companies seeking to reduce their CO₂ footprint, improve their ESG ratings and achieve preferred purchasing status with government agencies can benefit from the use of BioPreferred-certified materials. Zschimmer & Schwarz is committed to providing the world’s largest portfolio of eco-friendly, biodegradable and sustainable ester base stock options and to advance the science of environmentally acceptable lubricants.
