BASF is producing dispersions for interior paints using renewable raw materials.
The German chemical company says the paint binders use the “mass balance process,” which uses biomass instead of fossil raw materials.
To manufacture the binders of the Acronal brand, the company replaces 100 percent of the fossil resources used at the beginning of the production process with renewable raw materials. The paint producer DAW from Ober-Ramstadt, in Hesse, Germany, is already using one of these dispersions for its premium paints, BASF says.
Already during the production of the basic products for the dispersions, biomass is used as feedstock. With the help of the mass balance process, jointly developed by BASF and TÜV SÜD technical inspection board, the biomass share is then allocated to the dispersions according to their respective recipes. In terms of formulation and quality, the mass-balanced products are identical with their fossil counterparts, BASF says.
“Since these dispersions are based on the use of sustainably certified renewable raw materials in the production process, they help save fossil resources and reduce greenhouse emissions,” said BASF’s Robert Heger in a statement. “That way, we at BASF can help our customers develop interior paints that combine environmental responsibility with uncompromising premium quality.”
Heger is a vice president in charge of the dispersions business of BASF for construction and architectural coatings in Europe.
In September, BASF and Genomatica expanded their biochemical license agreement for the production of 1,4-butanediol based on renewable feedstock (renewable BDO) using Genomatica’s patented process. BDO and its derivatives are used for producing plastics, solvents, electronic chemicals and elastic fibers for the packaging, automotive, textile, and sports and leisure industries, among others.
