Developing Bioderived CO2-Responsive Polymers as Alternatives to Petroleum-derived Polymers
Researchers examined the development of bioderived, CO2-responsive polymers as sustainable alternatives to petroleum-derived plastics, using life cycle assessment principles and green chemistry frameworks to guide material design. The work addresses the environmental harms of petroleum-based plastic production and low recycling rates, proposing bio-based responsive polymers as a route toward materials with reduced environmental impact across their full lifecycle.
Environmental life cycle assessment of polyhydroxyalkanoates production by purple phototrophic bacteria mixed cultures
A life cycle assessment of polyhydroxyalkanoate (PHA) bioplastic production using purple phototrophic bacteria and municipal organic waste found that the photobiorefinery process dominates environmental impacts due to energy use and chemical inputs, but showed net carbon and fossil resource benefits compared to conventional plastics.
Defossilising fuels and chemicals – a systemic analysis from feedstock and technology, to hurdles and enablers
A systemic analysis examined the pathways and challenges of replacing fossil-derived fuels and chemicals with bio-based alternatives, highlighting trade-offs in sustainability and scalability. The work is relevant to reducing the fossil-plastic pipeline that drives ongoing microplastic pollution.
Harvesting marine plastic pollutants-derived renewable energy: A comprehensive review on applied energy and sustainable approach.
This review summarized recent research on recovering renewable energy from marine plastic waste through biological, chemical, and thermal conversion processes, evaluating each pathway's carbon efficiency, global warming potential, and economic viability as part of a circular economy approach to plastic pollution.
Planet compatible pathways for transitioning the chemical industry
Researchers modeled seven planet-compatible transition pathways for the global chemical industry to 2050, finding that combining resource efficiency, circularity, and feedstock substitution interventions could reduce chemicals demand by 23-33% and require total investments of US$1.2-3.7 trillion, with demand-side measures being critical to managing constraints on biogenic and recyclate feedstocks.
