ミズーリ大学の研究チームは、オレンジの香りの油を生成することで汚染水からマイクロプラスチックを捕捉する、遺伝子組み換え藻類を開発した。このプロセスは排水の浄化にも寄与し、バイオプラスチック生産を支える可能性がある。
工学部の教授であるスージー・ダイ氏が主導し、遺伝子工学を用いてこの藻類が作り出された。この藻類はリモネンを生成する。リモネンは藻類の表面を変化させて、水をはじく性質を持つマイクロプラスチックを引き寄せ、回収しやすい沈殿物へと変える。

Researchers at Flinders University say they have developed an adsorbent material that removed more than 98% of short- and long-chain PFAS—including hard-to-capture short-chain variants—in laboratory flow-through tests using model tap water. The approach embeds nano-sized molecular cages into mesoporous silica and, in the experiments reported, could be regenerated while remaining effective over at least five reuse cycles.
Researchers at the University of Michigan have discovered that common nitrile and latex lab gloves release particles resembling microplastics, potentially inflating pollution estimates. The study, led by Madeline Clough and Anne McNeil, traced contamination to stearates in the gloves during sample preparation. Switching to cleanroom gloves could reduce false positives significantly.

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
Researchers from India and Singapore report a crystalline membrane made from polyoxometalate clusters whose intrinsic openings are about 1 nanometer wide, enabling unusually sharp molecular separations that could help lower energy use in some industrial purification and water-reuse steps.
