Evaluation of biological degradation of polyurethanes
AI summary Read the abstract
This review paper rounds up what scientists currently know about how bacteria and enzymes can break down polyurethane (PU), a common plastic found in foam, coatings, and countless everyday products. The findings matter because breaking plastics down biologically (instead of them just fragmenting into microplastics that linger in our environment and bodies) could lead to safer, eco-friendly materials and better recycling methods. It's a research roundup rather than a new experiment, but it lays the groundwork for developing plastics that break down cleanly instead of turning into the tiny plastic particles now being found in human blood and organs.
Polyurethanes (PU) are a family of versatile synthetic polymers intended for diverse applications. Biological degradation of PU is a blooming research domain as it contributes to the design of eco-friendly materials sensitive to biodegradation phenomena and the development of green recycling processes. In this field, an increasing number of studies deal with the discovery and characterization of enzymes and microorganisms able to degrade PU chains. The synthesis of short lifespan PU material sensitive to biological degradation is also of growing interest. Measurement of PU degradation can be performed by a wide range of analytical tools depending on the architecture of the materials and the biological entities. Recent developments of these analytical techniques allowed for a better understanding of the mechanisms involved in PU biodegradation. Here, we reviewed the evaluation of biological PU degradation, including the required analytics. Advantages, drawbacks, specific uses, and results of these analytics are largely discussed to provide a critical overview and support future studies.

Mechanisms of Biological Degradation of Microplastics in the Environment
AI summary Read the abstract
This review paper rounds up what scientists currently know about using bacteria and other microbes to break down microplastics in the environment, including how special microbial enzymes attack different plastic types. While this research focuses on cleaning up plastic pollution rather than direct health effects, it matters to us because microplastics have been found in our food, water, and even our bodies—so finding better ways to break them down in nature could ultimately reduce our long-term exposure to them.
Biocatalytic Degradation of Industrial Polyurethane Waste Using Laccases
AI summary Read the abstract
Scientists tested natural enzymes called laccases to break down polyurethane, a common plastic found in foams, coatings, and many household products. This matters because polyurethane waste is difficult to recycle and can break into microplastics that pollute our environment and potentially our bodies. Using enzymes instead of harsh chemicals offers a gentler, more sustainable way to manage this plastic waste problem.
Understanding visible light and microbe-driven degradation mechanisms of polyurethane plastics: Pathways, property changes, and product analysis
AI summary Read the abstract
Researchers found that polyurethane plastics break down in water through a combination of microbial action and light exposure, producing secondary microplastics as they degrade. This study reveals a previously underappreciated source of microplastic pollution, since polyurethane is widely used in coatings, foams, and other products that often end up in waterways.
