Pesquisadores da Universidade do Missouri desenvolveram uma linhagem modificada de algas que captura microplásticos de água contaminada ao produzir um óleo com aroma de laranja. O processo também limpa águas residuais e pode apoiar a produção de bioplásticos.

Susie Dai, professora da Faculdade de Engenharia, liderou a criação das algas por meio de engenharia genética. As algas produzem limoneno, que altera sua superfície para atrair microplásticos hidrofóbicos e formar aglomerados que afundam, sendo mais fáceis de coletar.

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

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 fevereiro 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.
