plastics

Based on a defense protein of the strawberry anemone, researchers from the Barcelona Supercomputing Center, CSIC and the Complutense University of Madrid have designed, through artificial intelligence and the use of supercomputers, an artificial protein capable of degrading PET micro and nanoplastics, such as those used in bottles. According to the authors, its efficiency is between 5 and 10 times higher than that of the proteins currently used and it works at room temperature. The results are published in the journal Nature Catalysis.

A few weeks ago, the European Food Safety Authority (EFSA) said that exposure to bisphenol A through food is a risk to human health. The agency recommended a much lower tolerable daily intake dose than it had its own previous recommendations. In this explainer, we review key facts and documents to cover this issue--which will continue to make the headlines in months and years to come.  

Most so-called compostable plastics require specific conditions to degrade that are only obtainable in industrial settings, warns a study published in the journal PLoS One. Polylactic acid - a polymer obtained from natural renewable sources that is used as an alternative to petroleum-based plastics - takes more than a year to degrade in a marine environment, compared to 35 days for natural cellulose fibres, according to the analysis, which combines observations in waters off the coast of California (US) with laboratory measurements.
