  • Patent-pending PET caps and tamper-resistant closures can be cost-competitively produced using recycled PET or bio-based PET
  • “Mono-material” makes “100% recycled PET” possible from cap to bottle and improves recyclability because it is all one material, without the need for recyclers to separate caps from bottles
  • PET offers better oxygen and CO2 barrier than HDPE and PP, common cap materials
Origin Materials, Inc. (“Origin,” “Origin Materials,” or the “Company”) (NASDAQ: ORGN, ORGNW), the world’s leading carbon negative materials company with a mission to enable the world’s transition to sustainable materials, today announced it has created “all PET” (polyethylene terephthalate) bottle caps, making “100% recycled PET” possible from cap to bottle to improve post-consumer recycling.

Origin’s PET caps are more sustainable than common alternatives because they may be produced with any type of PET, from recycled PET to Origin’s 100% bio-based, carbon-negative virgin PET. PET offers better oxygen and CO2 barrier than HDPE and PP, common cap materials.

Origin’s patent-pending, cost-competitive design and manufacturing innovation aids in producing “mono-material” products. These are composed of only a single type of material, are typically easier to recycle than products made from multiple materials, and are highly sought-after for consumer packaged goods to improve recycling.

“We identified a global sustainability challenge and an opportunity to solve it,” said John Bissell, Co-Founder and Co-CEO of Origin Materials. “An all-PET bottle and cap and closure system is an obvious, necessary next step in beverage packaging and recycling. With our process, we can make caps from 100% recycled PET or 100% bio-based PET, unlocking important sustainability and potentially performance benefits for our customers.”

Origin’s innovation is expected to begin to address an approximately $65 billion global caps and closures market, anticipated to grow to $96 billion by 2030.

“This is what happens when you bring together some of the best materials and polymer scientists and engineers in the world under one roof,” said Bissell. “We saw an obvious need for a mono-material solution and the creativity of our team rose to the challenge. I am proud that our team’s expertise in PET led to this tremendous advancement for recycling.”

Cap tethering mandates, designed to incentivize the recoverability and recyclability of bottles, could further increase the demand for Origin’s innovative caps and closures. Tethering mandates require that caps remain firmly attached to bottles after opening and during the product’s life cycle, with the aim of reducing plastic litter on beaches and in the ocean. While traditional caps must be separated from PET bottles during recycling, Origin’s PET caps would not need to be separated from their tethered containers and could thus be recycled simply and easily.

About Origin MaterialsHeadquartered in West Sacramento, Origin Materials is the world’s leading carbon negative materials company. Origin’s mission is to enable the world’s transition to sustainable materials. For over a decade, Origin has developed a platform for turning the carbon found in inexpensive, plentiful, non-food biomass such as sustainable wood residues into useful materials while capturing carbon in the process. Origin’s patented technology platform can help revolutionize the production of a wide range of end products, including clothing, textiles, plastics, packaging, car parts, tires, carpeting, toys, fuels, and more with a ~$1 trillion addressable market. In addition, Origin’s technology platform is expected to provide stable pricing largely decoupled from the petroleum supply chain, which is exposed to more volatility than supply chains based on sustainable wood residues. Origin’s patented drop-in core technology, economics and carbon impact are supported by a growing list of major global customers and investors.
