This is a great thing to see - an explicit recognition of the value of waste. Indeed, the article even takes a similar tack to what I've been advocating. Rather than calling these materials "waste", call them "byproducts" and seek to maximise the information surface area so that the waste can be used.
This particular article refers to how the public sector is helping the private sector make these connections. Imagine the power when the free-wheeling dynamism of entrepreneurial business gets in on the act!
