Reviews examine biobased polymers

Several recent reviews examine the value chain of biobased polymers; discuss clarification of terms such as biobased, degradable, biodegradable, and compostable; define “biotechnological recycling (bio-recycling)” as the use of enzymes and microorganisms in a technological setting to biodegrade polymers; three biodegradable polymers assessed in marine field trials

Researchers propose Global Plastic Pollution Observation System

Environmental Science and Technology publishes paper proposing the establishment of the Global Plastic Pollution Observation System; would assist evidence-based policymaking by standardizing data collection on plastic pollution in atmospheric, terrestrial, and aquatic ecosystems; serve as “umbrella” by partnering with existing programs and initiatives at multiple scales

European Commission publishes Single-Use Plastics Directive guide

The European Commission (EC) published a guide for applying Directive (EU) 2019/904 on the reduction of the impact of certain plastic products on the environment, known as the Single-Use Plastics (SUP) Directive; defines plastics and SUPs; composite materials and biodegradable plastics included in Directive; Member States must have measures in place by July 3, 2021

Study assesses migration from recycled HDPE milk bottles

Paper in Resources, Conservation, and Recycling investigates chemical migration from recycled high-density polyethylene (rHDPE); when recycled milk bottles mixed with non-milk-bottle rHDPE, resulting plastic contaminated with chemicals of concern; rHDPE from well-sorted, decontaminated milk bottles may be clean enough for food contact; octocrylene and octinoxate still migrate at concerning levels, reduction may require further decontamination or changes in manufacturing or legislation

Plastics Pact launched in Oceania

Sixty stakeholders in Australia, New Zealand, and the Pacific Islands form ANZPAC, join the Ellen MacArthur Foundation’s global Plastics Pact initiative; 11th plastic pact overall, second regional pact and first in Oceania; 2025 goals include: 100% of plastic packaging to be reusable, recyclable or compostable, 25% increase in plastic packaging collected and recycled by each country in the region

Chile passes comprehensive plastics legislation

Chilean legislature unanimously passes comprehensive single-use and recycled plastics regulations; regulation bans single-use plastic use within a food establishment, compels markets and convenience stores to only sell recyclable beverage containers, beverage containers must contain plastic collected and recycled within Chile; regulations come into effect over 3 years

Reports investigate packaging and plastics in Africa

Two recent reports published by the African Circular Economy Alliance related to food packaging; “Five Big Bets to Africa’s path to Circularity” looks at opportunities to support African economy and environment, reviews current plastics and packaging infrastructure; “Building the African Circular Economy: Focus on Plastics” is a detailed research report of the plastics economy across Africa

Index identifies largest single-use plastic producers

Minderoo Foundation publishes “Plastic Waste Makers Index”; identifies 20 firms that produce polymers responsible for 55% of world’s plastic waste; calculates and illustrates global plastic flows from production through to end of life; provides recommendations for polymer producers, investors and banks, policymakers, and other companies along supply chain to enable shift towards circular economy

Review finds plastic pollution qualifies as planetary boundary threat

Review in Environmental Science and Technology presents evidence that plastic pollution fulfills all three criteria necessary for consideration as a planetary boundary threat: global exposure, not easily reversible, creating hazards disrupting earth system processes; suggests research priorities to find extent of planetary boundary but states risk that “boundary threshold for environmental plastics could be crossed before it is known”

Canada paves way for future regulations on plastics

Government lists plastic products in Schedule 1 of the Canadian Environmental Protection Act (CEPA) as “toxic”; legal step required in order to move forward with new regulation, product restrictions; will support government in implementing national plastic plans
