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.
A research team has outlined a fluorescence-based strategy designed to make microplastics and nanoplastics visible inside living organisms, potentially enabling real-time tracking of how the particles move, change and break down in biological systems.

Researchers at Flinders University have developed a thin, flexible film using milk protein, starch, and nanoclay that fully breaks down in soil within 13 weeks. The material aims to serve as an eco-friendly alternative to single-use plastics for food packaging. The study, published in Polymers, highlights its potential to reduce plastic pollution.
Researchers in Nigeria have reviewed a technology that mixes small amounts of water into diesel fuel to reduce emissions. This water-in-diesel emulsion, or WiDE, lowers nitrogen oxide and particulate matter by more than 60 percent without needing engine modifications. The approach may also boost fuel efficiency in some cases.

Dr. Mark Heilman, vice president of environmental restoration at SePRO, highlights how phosphorus from lawn care contributes to harmful algal blooms in US lakes and rivers. In a podcast episode, he shares successes in restoring polluted waters and stresses the importance of prevention over remediation. The discussion covers invasive species and climate impacts on water quality.
