Moringa seeds clean tap water by removing nearly all microplastics in lab study

Researchers in Brazil and the UK found moringa seed extracts act as a natural coagulant that removed about 98.5% of PVC microplastics from tap water in filtration tests, performing similarly to or better than alum and offering renewable, biodegradable advantages. Yet each seed treats only about 10 liters, raising scalability questions for large plants and leaving open questions about residues and effectiveness on other plastics or nanoplastics, necessitating further study especially for small communities.

Innovative Foam Solutions Revolutionize Microplastic Removal

Researchers from the University of Wuhan have developed a sponge made from cotton and squid bone that can absorb 99.9% of microplastics from water, offering a potential large-scale solution to global microplastic pollution. The sponge's production is scalable and cost-effective, addressing previous challenges faced by microplastic filtration systems. This innovation could significantly impact public health by reducing microplastic exposure, which is linked to various health risks. The sponge has shown high reusability and effectiveness in diverse water bodies, and could be adapted for use in household and municipal filtration systems.

Recycling Contributes to Microplastic Pollution.

A new study has found that plastic recycling centers can still produce microplastics that contaminate the air and water, even with filtering systems in place. The study focused on a single facility and found that the total discharge from different washes could produce up to 75 billion particles per cubic meter of wastewater. More than half of the microplastics can be captured with a filtration system, but the researchers warn that recycling centers may be exacerbating the microplastics crisis, which is coating every corner of the environment with synthetic particles.
