ClearHarnessing CO₂ for the Development of Biodegradable Polymers: A Review of Innovations in Green Chemistry
This review covers recent advances in making biodegradable polymers from captured CO2, an approach that simultaneously reduces greenhouse gas emissions and creates plastic alternatives that break down more readily than conventional plastics. The authors survey catalyst development, polymerization methods, and material properties of CO2-derived polymers like polycarbonates and polyurethanes. While not about existing microplastic pollution, replacing conventional plastics with CO2-based biodegradable materials could reduce both carbon emissions and long-term microplastic accumulation in the environment.
Bio-based plastics – a sustainable solution to plastic pollution
This review outlines the production, properties, and sustainability potential of bio-based plastics derived from renewable or recycled raw materials, arguing they can form part of a circular economy with lower carbon footprints than conventional petroleum-based plastics.
Bio-based plastics in a circular economy: A review of recovery pathways and implications for product design
Researchers reviewed how bio-based plastics — made from renewable plant sources — can be recovered and recycled at end-of-life, finding that the feasibility of eight different recovery methods depends heavily not just on plastic chemistry but on how products are designed, and offering guidance for designers to improve recyclability.
Designing biodegradable alternatives to commodity polymers
This review examined the challenges and strategies for designing biodegradable alternatives to commodity polymers, acknowledging that while replacement is necessary, sustainable alternatives must match the performance and economics of conventional plastics.
Methodology to address potential impacts of plastic emissions in life cycle assessment
Researchers proposed a new method for including the environmental impact of plastic emissions in life cycle assessments, which currently tend to make plastic products appear less harmful than alternatives. The approach introduces characterization factors based on how long different plastics persist in the environment. The study suggests that accounting for plastic pollution in these assessments could significantly change how the environmental footprint of plastic products is evaluated.

Bioplastics as Better Alternative to Petroplastics and Their Role in National Sustainability: A Review
This review examines bioplastics as a more environmentally sustainable alternative to petroleum-based plastics, discussing their advantages including lower carbon footprint and biodegradability, while noting that higher production costs currently limit their ability to compete with conventional plastics.
Redesigning Carbon–Carbon Backbone Polymers for Biodegradability–Compostability at the End-of-Life Stage
This review discusses strategies for redesigning carbon-carbon backbone polymers, which comprise 77% of global plastics, to be biodegradable and compostable at end-of-life, addressing the persistent microplastic pollution problem caused by conventional non-biodegradable plastics.
The future of plastic
Researchers examine whether biodegradable polymers can solve plastic's environmental crisis, noting that while plastic is enormously useful, society's heavy reliance on it has created a global pollution problem that biodegradable alternatives alone are unlikely to fully resolve.
Minimizing the environmental impacts of plastic through eco-design
Researchers developed a sustainability metric for eco-designing plastic products with low environmental persistence by integrating the environmental degradation rate of plastics into established material selection frameworks. The approach allows designers to compare materials on both functional performance and environmental persistence using material property indices.
Innovations in applications and prospects of bioplastics and biopolymers: a review
Researchers reviewed the chemistry, applications, and market outlook for bioplastic polymers including PHA, PLA, and cellulose-based materials, finding they offer meaningful environmental advantages over petroleum plastics but require further economic and performance optimization before achieving widespread commercial adoption.

The authors assess the performance, environmental fate, and scalability of current biodegradable materials, identifying key challenges for widespread adoption across packaging and consumer product applications.
Pathways to sustainable plastics. Unlocking opportunities in biobased plastic
This report examines pathways toward sustainable plastics production, finding that manufacturing new plastic from recycled content is the preferred circular economy route and that biobased feedstocks from biomass, recycled plastics, and CO2 can enable a transition away from fossil-based polymer production.
