Researchers create #plastic alternative that's #compostable in home and industrial settings
Story by Isabelle Butera, August 7, 2023
"The team worked with #polylactic acid, or #PLA, which has been used in packaging for over a decade. Instead of #petroleum (like typical plastic), it uses plant sugars and breaks down into water, carbon dioxide and lactic acid.
"But PLA can only break down in the heat of industrial #composters, not home composters. Even in industrial composters, PLA doesn't always break down quickly or completely.
"It can take as much as 20 days before PLA starts to be digested by microbes in an industrial compost setting, researchers said.
"To accelerate this process, the team incorporated what's called a 'thermoplastic starch' into PLA. This carbon-based starch helps the microbes in compost more easily break down the bioplastic.
"Adding the thermoplastic starch will not compromise the quality of PLA, such as the strength, clarity and other desirable features, researchers said in the release.
"Additionally, the bioplastic can be composted alongside food scraps. That means you wouldn't have to rinse food out of takeaway containers or coffee out of a disposable cup before throwing it out."

From the State of #Maine:
Alternatives to #PFAS in #Food #Packaging [PDF]
"PFAS in Food Packaging
The Department of Environmental Protection (Department) invites stakeholder comment on the attached department rule concept draft language which would prohibit manufacturers, suppliers, and distributors from offering for sale or for promotional purposes in Maine certain types of food packaging to which per- and poly-fluoroalkyl substances (PFAS) have been intentionally introduced, as authorized by Maine Revised Statutes, Title 32, Section 1733(3-B).
Maine law authorizes the Department to prohibit the sale of a food package to which PFAS have been intentionally introduced in any amount greater than an incidental presence if the Department determines that a safer alternative to the use of PFAS in a specific application to a food package is readily available in sufficient quantity and at a comparable cost, and that the safer alternative performs as well or better than PFAS in the specific application of PFAS to a food package.
In February 2021, the Washington State Department of Ecology (Washington DOE) published the Per- and Poly-fluoroalkyl Substances in Food Packaging Alternatives Assessment, identifying 4 types of food packaging that meet Washington’s statutory criteria for a prohibition:
Food Packaging Type and Alternative Identified as Safer
Wraps and liners - Wax-coated alternatives
Plates - Clay-coated and reusable alternatives
Food boats - Clay-coated and reusable alternatives
Pizza boxes - Uncoated alternatives
In May 2022, Washington DOE published a second alternatives assessment report, Safer Alternatives to PFAS in Food Packaging, which modified their process in two ways: first, by adjusting the concept of food packaging application to be more focused on its function rather than the package’s name; second, by relying on marketability to demonstrate cost and availability rather than direct price comparison of final products. This report identified safer alternatives for all five of the food packaging applications reviewed:
Food Packaging Type and Alternative
Bags and sleeves - Densified paper and wax-coated options
Bowls - Clay-coated, polylactic acid-coated, polylactic acid foam, and reusable options
Flat serviceware - Clay-coated, polylactic acid-coated, polylactic acid foam, and reusable options
Open-top containers - Clay-coated, densified paper, wax-coated, polylactic acid-coated, polylactic acid foam, aluminum, and reusable options
Closed containers - Clay-coated, polylactic acid-coated, polylactic acid foam, and aluminum options
Because language in Washington’s related law mirrors criteria for determination in Maine law, the Department proposes to rely on the conclusions in these reports that the safer alternatives identified perform as well as, or better, than PFAS in the specific applications of PFAS to the food package.
The Department requests written comment on this section of the Rule Chapter 80 Concept Draft by August 21, 2023.
"The Department intends to initiate formal rulemaking with the Board of Environmental Protection this fall to amend the existing Chapter 80 to incorporate these prohibitions. This will be a major substantive rulemaking subject to review by the legislature before final adoption.
"Please email Kerri.Malinowski@maine.gov with your name, affiliation, contact information, and comment in response to this request for stakeholder engagement."
