Turning Plastic Waste Into Clean Hydrogen With a Low-Temp Alkaline Process

A study published in PNAS describes an alkaline thermal treatment (ATT) that converts mixed plastic waste into high-purity hydrogen at lower temperatures with negligible direct CO2 emissions, potentially tackling both plastic pollution and clean-energy needs. Lab tests on PET, PE, and PP show hydrogen yields comparable to pyrolysis/gasification, with a need for pre-treatment of some plastics. While promising, researchers caution that scalability, economic viability, and full life-cycle environmental impact still require further research, along with handling contaminated plastics and recycling the sodium hydroxide.

Plastic at the Hadal Depth: The Challenger Deep Sighting and the Broader Deep-Sea Debris Trend

Plastic at the Hadal Depth: The Challenger Deep Sighting and the Broader Deep-Sea Debris Trend

In 2019 Victor Vescovo reached about 10,927 metres in the Challenger Deep and reported seeing something that looked like a plastic bag, but the observation was hedged and not recovered; subsequent analysis notes that a JAMSTEC study had already logged a plastic bag at 10,898 metres, and broader research shows single-use plastic debris is common at hadal depths, making the general claim of plastic in the deep sea well-supported even if the specific bag sighting isn’t definitively confirmed.

Hard-to-die plastic: PET bottles linger for centuries and seed microplastics globally

A PET water bottle takes about 450 years to decompose; since the 1970s essentially every bottle produced remains somewhere on Earth, gradually fragmenting into microplastics that are now found from Arctic ice to deep Mariana Trench sediments, while global plastic production continues and most of it remains unrecycled, ensuring centuries of pollution as plastics persist and disperse through air, water, and soils.

Maryland researchers near breakthrough in biodegradable packaging to curb plastic pollution

A University of Maryland research team says it is nearing a breakthrough to tackle plastic pollution by developing cost-effective biodegradable packaging using AI and biomolecular techniques drawn from shrimp and crab shells, with the aim of replacing plastic bags, wraps, water bottles, and other food-packaging materials.

San Diego rail nurdle settlement tightens transport rules for plastic pellets

A settlement over nurdle spills along San Diego-area rail lines leads BNSF Railway, the Coastal Environmental Rights Foundation, San Diego Coastkeeper, and the North County Transit District to adopt nationwide policies requiring sealed plastic-pellet rail cars, penalties for non-compliance, and a donation to local cleanup efforts, in an effort to curb plastic-pellet pollution.

Global plastics boom linked to rising health burden, study warns

Global plastics boom linked to rising health burden, study warns

A Lancet Planetary Health analysis estimates plastic pollution caused about 2.1 million global disability-adjusted life years in 2016 and could rise to roughly 4.5 million by 2040. Health harms come primarily from upstream plastic production and associated pollution rather than waste alone. The study argues for a cradle-to-grave, system-wide shift—reducing primary production while improving reuse and waste management—and urges stronger government action and industry transparency to curb the plastics health crisis.

Heat Boosts Microplastic Shedding from Takeaway Coffee Cups

Heat Boosts Microplastic Shedding from Takeaway Coffee Cups

A new study shows heat is the main driver of microplastic release from takeaway cups: all-plastic cups shed more particles than plastic-lined paper cups, and hotter beverages increase particle release. The researchers found a 300 mL daily hot coffee in polyethylene could lead to about 363,000 microplastics ingested annually. While long‑term health effects remain uncertain, the findings suggest using reusable cups or cooler drinks to reduce exposure, and avoiding pouring boiling liquids into plastic-lined containers.

Addressing Plastic Pollution: Strategies, Climate Impact, and Future Risks

The report updates on plastic pollution, highlighting that without urgent global action, plastic entering the environment will nearly double by 2040, causing severe health, environmental, and climate impacts. It emphasizes the need for transformative policies to reduce plastic production, improve waste management, and shift towards a circular economy to mitigate these risks and create economic opportunities.
