Rhode Island works hard to reduce air pollution in our communities. We passed laws to prohibit cars and buses from idling their engines and to retrofit school buses with diesel pollution controls. But there is only so much a single state can do, particularly against out-of-state pollution.
For one work we developed a human hair felt, which involved collecting and sorting hundreds of kilos of human hair, and then blending it will a tiny percentage of black merino followed by carding and felting.
