طور باحثون في جامعة ميسوري سلالة معدلة من الطحالب تلتقط المواد البلاستيكية الدقيقة من المياه الملوثة عن طريق إنتاج زيت برائحة البرتقال. وتساهم هذه العملية أيضاً في تنقية مياه الصرف الصحي وقد تدعم إنتاج البلاستيك الحيوي.
قادت سوزي داي، وهي أستاذة في كلية الهندسة، عملية تطوير هذه الطحالب من خلال الهندسة الوراثية. تنتج الطحالب مادة الليمونين، التي تغير سطحها لجذب المواد البلاستيكية الدقيقة الكارهة للماء وتشكيل كتل غارقة يسهل جمعها.

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.
