Six months ago the folks at Target asked us to solve two problems. They wanted to solve the plastic bag problem and they wanted a new designer bag to sell. We solved them both simultaneously. Everyone knows how big the plastic bag problem is. According to the Wall Street Journal, the U.S. goes through 100 billion plastic shopping bags annually. Plastic bags don't biodegrade. Instead, they photo-degrade, breaking down into smaller and smaller toxic bits that contaminate soil and waterways and enter the food web when animals accidentally ingest them. On top of this, it can cost up to $4,000 a ton to recycle plastic bags, and the resulting polymers are worth only a fraction of the cost, rendering the recycling of plastic bags economically unsustainable. Since legislated plastic bag collection exists only in select parts of California, the vast majority of plastic bags are discarded improperly.
