Booming prices for resins, the building blocks for plastic, have already helped drive up the cost of making everyday products such as toys, bottles and face masks.

Now the fossil-fuel-derived ingredient could get even more expensive as Russia’s attack on Ukraine raises the risk of higher oil prices, potentially trickling down to what consumers pay for household and personal care products. Brent crude had already risen almost 48% in the last year.

Lab turns hard-to-process plastic waste into carbon-capture master

via Phys.org

What seems like a win-win for a pair of pressing environmental problems describes a Rice University lab’s newly discovered chemical technique to turn waste plastic into an effective carbon dioxide (CO2) sorbent for industry.

Rice chemist James Tour and co-lead authors Rice alumnus Wala Algozeeb, graduate student Paul Savas and postdoctoral researcher Zhe Yuan reported in the American Chemical Society journal ACS Nano that heating plastic waste in the presence of potassium acetate produced particles with nanometer-scale pores that trap carbon dioxide molecules.

Chemists cook up way to remove microplastics using okra

Cooking up a way to remove microplastics from wastewater — with okra, aloe

via the American Chemical Society.

SAN DIEGO, March 22, 2022 — In many cuisines, okra serves as a master thickener of stews and soups. The goo from that fruit and other plants, such as aloe, cactus and psyllium, can also clean water and wastewater of some types of solid pollutants, as well as some that are dissolved. Now, researchers have demonstrated that combinations of these food-grade plant extracts can remove microplastics from wastewater.

The health effects of ingesting microplastics — tiny pieces of plastic 5 mm or smaller — are currently unclear, but studies suggest that people unintentionally consume tens of thousands of these particles every year. “We think that microplastics by themselves may not be much of a health hazard, but anything that they get into or any type of toxic substance that gets attached to these plastics could go inside our bodies and cause problems,” says Rajani Srinivasan, Ph.D., the principal investigator for the project.
