90% of products are shipped in cardboard containers. On average, a typical household will throw away up to 13,000 pieces of cardboard a year. In the US, 850 million tons of paper and cardboard — the equivalent of 1 billion trees — are thrown away each year. The good news is that recycling old cardboard into new cardboard takes only 75% of the energy needed to manufacture new cardboard. You are helping save trees when you toss in your cardboard.
