The first sentence of the article mentions that the key problem is the microplastics that have reached the ocean. Cutting off one source is valuable, but that will still leave lots of microplastics in the ocean. I don't think aiphex is wrong to comment on the technology's limitations. Why do you think that the inability to solve a related problem (microplastics in laundry wastewater vs in the ocean) with the same technique is too far off topic?
