As Congress and the Trump administration contemplate a $1 trillion investment in infrastructure, the question of how to utilize those dollars looms large. If the focus is just asphalt and concrete, it will miss the heart of American manufacturing. At the top of manufacturers’ needs is access to good, consistent, high-quality feedstocks to make into new products. Let’s help meet that need with some of the best possible domestic sources of raw materials: the paper, plastics, glass, metals and packaging discarded by U.S. homes and businesses. That means including funding for improved recycling in the infrastructure bill as a way to ensure long-term reliable supply created right here at home.
