Abstract Plastic pollution is becoming a major health issue due to the recent discovery of microplastics and nanoplastics in living organisms environment, calling for advanced technologies remove plastic waste. Here we review enzymes that degrade plastics with focus on properties, protein engineering polymers such as poly(ethylene terephthalate), poly(butylene adipate-co-terephthalate), poly(lactic acid), polyamide polyurethane. The mechanism action natural engineered has been probed by experimental computation approaches. performance polyester-degrading improved via directed evolution, structure-guided rational design machine learning-aided strategies. display higher stability at elevated temperatures, tailored substrate-binding sites.

Plastics offer several advantages, but their production and disposal processes have severe environmental implications. To overcome these issues, there is a need to switch from the linear circular economy by recycling plastic waste utilizing renewable resources create bioplastics. However, this challenging in case of nonbiodegradable polyolefins (POs), which form largest fraction produced polymers least recycled one. Mechanical recycling, chemical PO bioplastics are three pillars economy. Although mechanical an environmentally economically viable option, it often results degradation downgrading POs. Nonetheless, innovations such as use (nano)fillers or compatibilization with olefin block copolymers, attempt mitigate issues. Furthermore, development covalent adaptable networks improves properties thermoplastics provides recyclable elastomers. If fails meet desired characteristics recyclate PO, other chemicals potential alternative. retrieving monomer ideal for achieving closed-loop economy, traditional approaches noncatalytic POs energy-intensive lack specificity. This has been tried be addressed advancements catalytic approaches. Finally, biobased polyolefins, especially those through emerging nonbiochemical approaches, attractive alternatives that can integrated into existing petrochemical plants. With comprehensive perspective on academic industrial researchers field better contribute more sustainable future.

Abstract Bioplastics, comprised of bio‐based and/or biodegradable polymers, have the potential to play a crucial role in transition towards sustainable circular economy. The use polymers not only leads reduced greenhouse gas emissions but also might address problem plastic waste persisting environment, especially when removal is challenging. Nevertheless, plastics should be considered as substitutes for proper management practices, given that their biodegradability strongly depends on environmental conditions. Among challenges hindering implementation bioplastics market, development effective downstream recycling routes imperative, increasing production volumes these materials. Here, we discuss about most advisable end‐of‐life scenarios bioplastics. Various strategies, including mechanical, chemical or biological (both enzymatic and microbial) approaches, considered. Employing enzymes biocatalysts emerges more selective environmentally friendly alternative recycling, allowing new added value high‐quality products. Other pending concerns industrial include misinformation among end users, lack standardised bioplastic labelling, unclear life cycle assessment guidelines need higher financial investments. Although further research efforts are essential foster widespread application bioplastics, significant strides already been made this direction.

This work evaluates the preparedness of packaging industry towards more circular, sustainable solutions for fresh meat and fish. The term bioplastic is ill-defined, creating confusion between all stakeholders in value chain. implementation as food contact material will only occur when there are demonstrated that can equally or better protect fish from spoilage, compared to conventional plastic. Price, supply chain availability, machinability, safety also be key shift fossil bioplastic. application at its infancy. In this work, a multidisciplinary approach was employed highlight need holistic eco-design minimizes waste, due high environmental footprint meat. Although bioplastics positively perceived by end-users, including consumers, widespread their market implementation. Their sorting end-of-life major challenges. chains underdeveloped, terms costs, scale-up, sorting, recycling even most promising materials. Most still do not meet specified technological functionalities required substitute fossil-fuel counterparts. For appropriate eco-design, it important quantify using life cycle assessment considering material-food unit importantly, ensure safety, demonstrating absence migration harmful substances packaging, especially derived waste byproducts. development active intelligent increase shelf products add significant food-packaging unit.
