Protecting the Environment

Solving the global plastics problem will take a lot of different steps.  Developing new materials that mimic the performance of conventional plastics, but which are found in nature and return to nature at the end of life is an important one.  That's where we come in.  It's taken decades or research and development to get to scalable production.  We're here.  We meet every biodegradable and compost standard.

PHA stands for polyhydroxyalkanoate, which represents a polyester made in the natural world (as opposed to chemically synthesized polyesters). PHAs are made using bio fermentation processes and are now being used to make drinking straws, coffee pods, films, cups, and coated papers.  We continue to perfect new applications.  One promising new area would use PHAs to replace polyester fibers in clothing (a leading culprit of microplastics when washed),

Understanding the Data behind Studies

PHAs meet all international standards for terrestrial and marine biodegradability as well as home and industrial composting.  They are approved for food contact applications, as straws, food ware and food packaging and in other applications such as substitutes for foam packaging and as compostable coffee pods.   PHAs meet the demand that closed loop products replace single use plastics.  PHA production and use is scalable.

 

We welcome rigorous standards because they separate us from companies that make misleading or exaggerated claims that confuse consumers.

What experts are saying

“…[PHAs] mimic the functionalities of many of the top-selling plastics of petrochemical origin, but biodegrade in soil, freshwater, and marine environments, and are both industrial- and home-compostable…PHA materials on the market or under advanced development mimic the properties of the seven most popular plastics, which account for 230 million tons of annual plastic production.”

ABOUT

THE PHA COALITION

The PHA Coalition is comprised of companies committed to producing and using PHAs to replace conventional plastics.  Our members range from California start-ups to some of the largest consumer brands in the world.  PHAs are made from numerous renewable feedstocks, including sewage waste gas, methane, waste cooking oil, and chitin from shrimp and crab shells.

PHAs are the only bioplastics that are fully biobased, home- and industrially compostable, soil- and marine biodegradable, and anaerobically digestible. PHAs meet all international standards for compostability and biodegradability.

PHAs are found in nature.  They return to nature and are environmentally and human safe.

"The Yankees are committed to achieving zero waste and promoting a circular economy based on composting, recycling, and the recovery and use of waste oil. Compostable cutlery and food-service packaging, trays, boxes, plates and cups, are used instead of non-compostable petroleum-based plastics. Food waste is composted and not landfilled, and cardboard, glass, metal, plastics and paper are recycled. Through the overall efforts of fans and Stadium staff, approximately 85 percent of the Stadium's total trash is diverted away from landfills, making Yankee Stadium one of the most successful recycling venues in all of sports."
