Old tires are finding many good and very commercially valid (economic) uses (price of products sold are greater than cost of collection, production, marketing and overhead).
I always thought glass was easy and economic to recycle (apply enough heat and it’s no longer a solid again and can be merged and divided again into new shapes in as good a quality as originally), whereas good glass must first obtain reasonably pure source material (sand). Am I wrong in thinking recycled glass is not economical?
in china they use old tires for soles on sandals. they probably would last quite a long time actually.
