In BASF’s biomass balance approach, renewable raw materials are used when manufacturing primary chemical products in the production site. The proportion of renewable raw materials is then attributed to certain sales products, according to a certified mass balance method.
SUSBINCO, which Teknos is a part of, is a research project based on the search for sustainable and safe alternatives to current fossil-based binders and coatings. The project was launched in response to the coating industry's need to replace fossil-based raw materials, and reduce greenhouse gas emissions.
A multi-step continuous process has been developed to convert renewably sourced furfural to 1,5-Pentanediol (1,5-PDO), which is a low-cost renewable replacement for 1,6-HDO, a diol intermediate currently used to produce coatings, adhesives and plastics.
Over the past couple of decades, there has been a lot of discussion, R&D, marketing and sales efforts aimed at converting as many products that are based upon fossil fuel-derived specialty chemicals to “green” (biosourced) analogs, as possible.
It was found that samples having a higher percentage of CNSL showed excellent corrosion scratch properties, and successfully passed the humidity and blistering tests. Analyzing the overall performance of the films derived from each sample, it may be said that all the samples showed good mechanical, chemical and corrosion resis¬tance, keeping cost in mind.
Soybean oil is economical and abundantly available from soybeans sustainably grown in the United States. The hydrophobic nature of this bio-based raw material is a dominant performance attribute in a multitude of coatings applications.
For companies looking for high-performance, nontoxic, sustainably produced solvents, a new bio-based solution offers a safer and high-performing alternative to the toxic dipolar aprotic solvents traditionally used in the paint and coatings industry.
Coatings provider Stahl, Waalwijk, the Netherlands, and Elevance Renewable Sciences Inc., a producer of specialty chemicals from renewable feedstocks, have signed a supply agreement.
