Thermoresistive Sensors Based on Eco‐Friendly Carbon Dioxide‐Derived Polymeric Poly(Cyclohexene)carbonate Loaded With Reduced Graphene Oxide and Carbon Black

open access: yesPolymer Engineering &Science, EarlyView.
Thermoresistive sensing materials derived from eco‐friendly polymers for broad‐range temperature measurements. ABSTRACT Carbon dioxide‐derived polycarbonates (CO2‐PCs) present a sustainable alternative to standard bisphenol A polycarbonates (BPA‐PCs), as they are synthesized from the reaction between epoxide and carbon dioxide (CO2). In fact, these eco‐

Statistical evaluation of nylon chemical recycling through acidolysis

open access: yesPolymer International, EarlyView.
Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...

Achieving Sustainable Development Goals Through Social Life Cycle Assessment: A Case Study of Portuguese Forest Wood Supply Chains

open access: yesSustainable Development, EarlyView.
ABSTRACT Social considerations are often overlooked in efforts to achieve sustainable development, despite being critical for building equitable and resilient global value chains. This study addresses this gap by applying a social life cycle assessment to three key Portuguese forest wood supply chains—uncoated woodfree paper, natural cork stoppers, and
