Circular economy, bioeconomy, and sustainable development goals: a systematic literature review

Researchers conducted a systematic review of 649 studies examining how circular economy and bioeconomy concepts contribute to the United Nations Sustainable Development Goals. They found that while these approaches show promise for addressing environmental challenges including plastic waste, most research has focused on a limited set of goals and lacks empirical data. The study identifies key research gaps, including the need for more studies on economic and social impacts in developing countries.

A Review of Bioplastics and Their Adoption in the Circular Economy

This review examines the current landscape of bioplastics, including bio-based and biodegradable materials, as potential alternatives to conventional fossil-fuel-derived plastics. Researchers assessed standards, life cycle analyses, and environmental performance of various bioplastic types. The study highlights that while bioplastics offer potential benefits for reducing fossil resource dependency, challenges remain around their actual environmental performance and integration into circular economy systems.

Contribution to a Circular Economy Model: From Lignocellulosic Wastes from the Extraction of Vegetable Oils to the Development of a New Composite

Researchers developed a fully bio-based composite material using bio-derived polyethylene from sugar cane and chia seed oil extraction by-product as filler. This circular economy approach to bioplastic composites could replace petroleum-based plastics and reduce the microplastic pollution that comes from conventional plastic degradation.

Economia Circular E Desenvolvimento Sustentável: Compostabilidade, Biodegradação E Inovação Em Biopolímeros E Compósitos Renováveis Para Aplicações Estruturais, Agrícolas E Embalagens

This review paper summarizes research on new plant-based plastics that can break down naturally in the environment, unlike regular plastics made from oil. These eco-friendly materials could replace traditional plastic in food packaging and farming, potentially reducing the tiny plastic particles that end up in our food and water. However, the technology still needs improvements and better waste management systems before these biodegradable plastics can widely replace regular plastics.

Bioplastics for a circular economy

Researchers reviewed the role of bioplastics — made from bio-based or biodegradable polymers — in circular economy systems, finding that while they can lower carbon footprints and enable end-of-life biodegradation, trade-offs including land competition, unclear recycling compatibility, and higher costs limit their scalable sustainable impact.

Are Reliable and Emerging Technologies Available for Plastic Recycling in a Circular Economy?

This review examines the current landscape of plastic recycling technologies -- including mechanical, thermal, chemical, and biological depolymerization methods such as pyrolysis -- evaluating their readiness for circular economy integration. It concludes that while recycling rates remain below 10% globally, emerging technologies offer pathways toward closed-loop plastic supply chains, though full-scale implementation requires further development and performance assessment.

Bioplastics in the circular bioeconomy: Production pathways, biodegradation mechanisms, and environmental implications

This comprehensive review examines how bioplastics — plastics made from renewable biological sources — fit into a circular economy, covering how they are produced, how microorganisms break them down, and the environmental risks when degradation is incomplete. A key concern is that even bio-based plastics can form microplastics if they do not fully degrade in real-world conditions like marine or soil environments, meaning that simply switching to bioplastics does not automatically solve the microplastic pollution problem.
