Polyolefins in the Circular Economy: Advances and Recyclability
AI summary Read the abstract
This review examines how polyolefins like polypropylene and polyethylene can be integrated into a circular economy through chemical recycling technologies, arguing that incorporating artificial intelligence and machine learning into current recycling processes is essential for modernizing plastic waste management and creating sustainable value chains.
Abstract Plastics are widely used across various sectors, with polyolefins such as polypropylene (PP) and polyethylene (PE) making up a significant portion of global consumption. These materials are produced through olefin polymerization using diverse technologies, and their properties are tailored to meet the needs of different industries. Despite their benefits, plastics are often criticized for their environmental impact due to improper waste management, leading to littering on land and in oceans. Therefore, an intelligent and sustainable waste management system is essential to transform plastic waste into valuable resources and prevent pollution.This review article focuses on the production of value-added products through various recycling techniques, particularly the chemical recycling of polyolefins. Current technologies lack the integration of advanced tools such as artificial intelligence (AI) and machine learning (ML), which are necessary for modernizing these processes. Implementing AI and ML into existing technologies presents a significant challenge but is crucial for advancing recycling methods. The objective of this review is to highlight current polyolefin production technologies, address environmental concerns from plastic waste, and explore recycling techniques and novel processes to ensure a circular economy framework for a sustainable plastic value chain.

Chemical recycling of polyolefins: a closed-loop cycle of waste to olefins
AI summary Read the abstract
This review examines chemical recycling methods that can convert polyolefin plastic waste back into olefins, creating a true closed-loop cycle. Researchers describe how pyrolysis, including thermal, catalytic, and solvent-based approaches, breaks down plastic waste into reusable chemical building blocks. The study suggests that chemical recycling holds significant potential for addressing plastic pollution by turning waste into valuable raw materials rather than sending it to landfills.
Chemical Recycling and Upcycling of Plastic Waste: from Linear to Circular Economy
AI summary Read the abstract
This review paper rounds up scientific progress on turning plastic waste into new chemicals and materials—instead of just melting it down into lower-quality plastic (what most "recycling" does today, and only for 9% of waste). Better recycling methods matter for your health because plastic that isn't properly processed often ends up in landfills, oceans, or breaking down into microplastics that contaminate our food, water, and even our bodies. These emerging chemical methods could help close the loop on plastic waste, though the researchers note real challenges remain before this happens at scale, including cost and technical hurdles.
Chemical Recycling and Upcycling of Plastic Waste: from Linear to Circular Economy
AI summary Read the abstract
Right now, only about 9% of plastic waste actually gets recycled, and most of what does get recycled turns into lower-quality material—not a real solution to the mountains of plastic piling up in our environment (and breaking down into the microplastics we're increasingly finding in our bodies). This review rounds up newer "chemical recycling" methods that can break plastic waste down to its molecular building blocks and even transform it into useful products like lubricants, offering a more promising path to actually reusing plastic instead of just downgrading it. These technologies are still working through real challenges like cost and efficiency before they can make a major dent in the plastic p
Recent Advances in Catalytic Chemical Recycling of Polyolefins
AI summary Read the abstract
This review examines recent scientific advances in catalytic chemical recycling of polyolefins such as polyethylene and polypropylene, which account for nearly 50% of all plastic production by mass. Researchers highlight catalytic processes that can break down polyolefin waste at lower temperatures than pyrolysis, with the goal of upcycling discarded plastics into functional chemicals rather than sending them to landfill.
Cross-Linked Polyolefins: Opportunities for Fostering Circularity Throughout the Materials Lifecycle
AI summary Read the abstract
This review examines cross-linked polyolefins, a significant class of plastics that are typically incinerated or landfilled because they cannot be melted for reprocessing. Researchers assessed both traditional mechanical recycling and advanced recycling methods for improving circularity of these materials. The study highlights opportunities to reduce plastic waste through biobased feedstocks, extended product lifespans, and recyclable-by-design strategies for future cross-linked polyolefin products.
