US-based DaniMer Scientific is set to unveil a new biobased label adhesive, DaniMer 92721 to eliminate the problems associated with polyethylene terephthalate (PET) container recycling. The company used renewable building block, Susterra Propanediol from the suppliers Dupont Tate & Lyle and Myriant to develop the new adhesive.
The DaniMer 92721 has a renewable content, which is higher than 50% and dissolves completely in PET flake caustic wash recycling operations without clumps or 'stickies.' Its rheology enables it to operate in existing adhesive systems at temperatures under 325F.
Results from industry standard protocol testing revealed that the product enables zero contamination in PET recycle streams.
DaniMer Scientific founder and CEO Daniel Carraway said the company selected DuPont and Myriant as its suppliers for the project due to their capabilities and knowledge with the development of the renewable building blocks.
"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," Carraway added.
The US Department of Agriculture has certified the Susterra propanediol as 100% biobased. It can be used by the companies to add renewable content to their products.
