Plastics of the future will live many past lives, thanks to chemical recycling
01.12.2022
A research team at the University of Colorado Boulder has discovered how durable plastics used in the aerospace and microelectronics industries broken down into their most basic building blocks and then formed again into the same material. In the process, they do not lose their physical properties.
Recycled PET bottles are turned into adhesive tapes
26.10.2022
The company tesa® supports the field of sustainability. The new tesa® 60412 packaging tape has a backing made of 70% recycled PET and a water-based acrylate adhesive system. The production process is completely solvent-free. Used PET products are recycled and used as raw material for the backing material.
Researchers develop plastic film that can kill viruses using room lights
26.10.2022
Researchers at Queen's University Belfast have developed a plastic film that uses room light to kill viruses that land on its surface. The technology used to manufacture the film also ensures that it is degradable. This self-sterilizing film is inexpensive to produce, easy to scale and could be used for disposable aprons, tablecloths and curtains in hospitals.
Lessons from natural photosynthesis: conversion of CO2 to raw materials for plastic
21.10.2022
A research team at Osaka Metropolitan University has succeeded in producing fumarate from pyruvate and CO2 through artificial photosynthesis. Fumarate can be used to produce biodegradable plastic such as polybutylene succinate. In this process, the carbon is stored in a compact, durable and solid form.
Shining light on why plastics turn yellow
21.10.2022
A research team has investigated whether intended nanostructures formed by UV light could be the cause of yellowing of polyethylene. The result was that chiral chemical structures form on the surfaces of polyethylene films during exposure to UV light and are a possible cause of the yellow color of old plastics. These findings could help researchers develop plastic products that last longer.
Researchers find a new method for recycling polystyrene
11.10.2022
A research team led by Guoliang "Greg" Liu implemented the goal of making the current main method for recycling polystyrene profitable. By exposing the material to ultraviolet light and adding a chemical catalyst this method creates diphenylmethane (DPM), which has a high economic value. This new recycling method would create an incentive for polystyrene to be collected and recycled.
