For decades, building material companies have shredded old newspapers to create cellulose insulation. But as newspapers have declined, the cellulose insulation industry has found itself in a bind, chasing after dwindling supplies of raw material. People have increasingly turned to e-commerce, and the amount of cardboard boxes has crept steadily upward. To date, CleanFiber has been able to produce enough insulation for about 20,000 single-family homes. Plus, Strimling points out that more stringent building codes mean that new homes require more insulation than ever before.
