What could be better, buy a bottle of wine, drink the contents, sandblast a design on the bottle, sell it to buy a new bottle of wine.

Many more recycled products to come. Just using used bottles it's possible to make lamps, cheese trays, glassware, and wind chimes, to name just a few of the possibilities. Add to that the many other blastable recyclables and you have many saleable items that start with virtually free materials.
