Coca-Cola Goes Bioplastics

Coca-Cola will use recycled PET and plant-derived plastic in a Dasani water bottle, creating a package known as the “HybridBottle.” The move is one of several recycling-related changes being rolled out.

The beverage giant on Aug. 13 announced the packaging shifts for the Dasani brand, which is among the largest water brands in the U.S.

PlantBottle, which incorporates up to 30% plant-derived PET, has been used in a number of Coca-Cola beverages since its introduction in 2009. The company describes PlantBottle as the “first-ever fully recyclable PET plastic beverage bottle made partially from plants.”

Now, the company is mixing the plant-based plastic with recycled PET in a 1-to-1 ratio to create “HybridBottle.”

The development is part of an effort to “increase the use of recycled and renewable materials in the United States while ensuring that all Dasani bottles continue to be fully recyclable,” the company wrote.

This offering will be rolled out nationally in Dasani’s 20-ounce bottles in mid-2020.

Other recent Dasani announcements include:

  • The company will continue its packaging lightweighting across all Dasani products, “to support overall efforts to reduce the amount of virgin PET plastic procured by the Coca-Cola system,” according to the release.
  • Coca-Cola will switch Dasani packaging from plastic to aluminum. This will begin in the Northeast in the coming months, and aluminum cans will be rolled out into other markets next year. Additionally, Dasani will begin using aluminum bottles in some products in mid-2020.
  • Coca-Cola will use the How2Recycle label on all its Dasani packaging beginning this fall.

Coca-Cola framed the developments as part of its wider goal to make its bottles and cans with an average of 50% recycled material by 2030.




Mitsui Chemicals Enters Into Partnership Agreement With Plug and Play

Mitsui Chemicals, Inc. today announced that it has entered into a materials sector-based partnership agreement with Plug and Play, LLC (Founder & CEO: Saeed Amidi), a Silicon Valley-based firm that supports the growth of startups with innovative technologies and ideas.

Operating on a global scale, Plug and Play is a world-leading venture capital firm and startup accelerator, working alongside major companies to support startups that possess innovative technologies and ideas.

Since its establishment in 2006, the company has supported more than 2,000 startups, providing more than $7 billion in financing and helping to turn out numerous unicorn companies*.

New Bio-Epoxy Resin for Flame-Retardant Coating Applications

Novel phosphorus-containing epoxy resin from renewable resource for flame-retardant coating applications.

A phosphorus-containing epoxy resin has been derived from a renewable resource, sebacic acid (SA), and formulated for flame-retardant applications.

The synthesized epoxy resin was characterized by physicochemical and spectral analysis including Fourier-transform infrared (FTIR), 1H and 31P nuclear magnetic resonance spectroscopies.

Curing of the epoxy resin mixture was carried out with polyamide hardener at 1:1 stoichiometry on equivalent weight basis.

The developed coatings were characterized in terms of their mechanical, solvent, gel content, water absorption, chemical, thermal, and flame-retardant properties, while the glass-transition temperature and thermal stability of the coatings were analyzed by differential scanning calorimetry and thermogravimetric analysis, respectively.

The results revealed that the coatings with added SA-based epoxy resin showed good mechanical, chemical, and solvent-resistance properties.

The thermal profile of the coatings manifested that the char yield increased with the concentration of the SA-based epoxy resin.

Limiting oxygen index (LOI) and UL-94 tests were performed to understand the flame-retardancy behavior of the synthesized coatings, revealing an enhancement as the concentration of phosphorus-containing epoxy resin was increased.
