Investigadores de la Universidad de Misuri han desarrollado una cepa modificada de algas que captura microplásticos de agua contaminada mediante la producción de un aceite con aroma a naranja. El proceso también depura aguas residuales y podría apoyar la producción de bioplásticos.

Susie Dai, profesora en la Facultad de Ingeniería, lideró la creación de las algas a través de la ingeniería genética. Las algas producen limoneno, el cual altera su superficie para atraer a los microplásticos hidrofóbicos y formar cúmulos que se hunden, lo que facilita su recolección.

Flinders University team reports nano-cage adsorbent that captures short-chain PFAS in water tests

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 propose glow-in-the-polymer approach to track microplastics inside living organisms

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.

Scientists create milk-based biodegradable film for packaging

28 de febrero de 2026 Reportado por IA

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.

Water emulsion cuts diesel engine pollution by over 60 percent

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.

SePRO's Mark Heilman discusses phosphorus pollution in waterways

18 de febrero de 2026 Reportado por IA

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.
