US -
DaniMer Scientific LLC is releasing a new biobased label adhesive that the company claims will eliminate the problems associated with polyethylene terephthalate (PET) container recycling.

Utilizing renewable building blocks from Dupont Tate & Lyle and Myriant, DaniMer’s new label adhesive - DaniMer 92721 - is designed to meet the demands of PET container packaging recycling streams and has a renewable content higher than 50%.

The adhesive dissolves completely in PET flake caustic wash recycling operations without clumps or “stickies.”

According to DaniMer, this new bio-based formulation is competitively priced with block co-polymers, with pricing not linked to crude oil derivatives. In addition, rheology of DaniMer 92721 enables the adhesive to operate in existing adhesive systems at temperatures under 325F. Results from industry standard protocol testing show the product enables zero contamination in PET recycle streams.

“DaniMer is pleased to announce this advancement towards eliminating problems with PET recycling in streams,” said Daniel Carraway, Founder and CEO of DaniMer Scientific. “We have been actively engaged with our target market in order to understand what our consumers need, and the issue of PET contamination was a recurring and significant matter that needed to be resolved.

“Of course, we chose DuPont and Myriant as our suppliers for this project due to their world-class capabilities, knowledge and extensive background with the development of innovative, renewable building blocks.”

“The recycling industry has long been challenged to find ways to overcome the issues and complications associated with recycling PET containers,” said Stephen J. Gatto, Chairman and CEO of Myriant. “Myriant is proud that its high-performing bio-succinic acid is part of this innovative solution to a decades-old challenge. DaniMer’s new adhesive is a great example of the innovation and market opportunities available with bio-based chemicals.”

“Susterra® propanediol is certified 100% biobased by the US Department of Agriculture, making it attractive for companies seeking to add renewable content to their products. We are excited to be selected by DaniMer as a key ingredient for this new biobased adhesive technology,” commented Pete Colombo, account executive for DuPont Tate & Lyle Bio Products.
