As we strive towards a circular economy, the application of treated sewage sludge (biosolids) to land is an opportunity to enhance soil health and reduce the reliance on synthetic fertilizers.

    I feel like I can save a lot of time and energy here for scientists and the lay-person alike;

    They’re literally everywhere. The tallest mountains, the deepest caves, the bottom of the marinas trench, stop looking, because they’re there.

      They just found them in 50% of artery blockages, so we should probably keep looking so we can finally ban materials that degrade into them.

      There is a new process for treating wastewater sludge that destroys the microfibers, so that is good news at least. I think it may be expensive, of course. It is called “hydrothermal carbonization”. Basically put the sludge in a giant pressure-cooker and the heat breaks the plastics into carbon and some water-soluble residual molecules which can go back to the start of the wastewater treatment plant to be biodegraded. But like others say, the main source in general is tires - not sure if they know whether tire microplastics are the main source in agricultural land though.
