What happens to these nutrients at a sewage treatment plant?
I know that farmers collect the sludge for I assume fertilizer.
If that stage could be modified to keep the nutrients that seems like the best thing going forward.
- schiffern 4y agoSewage solids applied to farms are a major source of microplastic contamination,[0] likely since we currently commingle our valuable human waste with wastewater from washing machines. Synthetic textiles cause 35% of ocean microplastics[1] (ie the largest single source), so this is not a small waste stream.
