The True Challenge to Recycled Glass – Economics
Lucas Hamilton is Manager, Building Science Applications for CertainTeed Corporation
Recycled content is a key component of sustainable products. However, manufacturers often struggle to find recycled content because of economics. This is particularly true with regard to glass or cullet which is an ingredient in products such as fiber glass insulation.
The sad fact is that much of the glass in the U.S ends up in landfills because the economics of glass are such that on any given day the value of the glass may be much lower to the waste hauler than the cost of the fuel to take it over to the manufacturer who will buy it off their hands.
So on most days, in most parts of the U.S., we suffer from the fact that glass is not actually being recycled. Even though we put it in containers at our curbs, it doesn’t wind up getting back into the economy because its value is too low.
I’ve talked to many people about this and one option I came up with is to make glass more expensive. Artificially, this can be done through deposits or we can go to the real form which is to make glass more expensive. If it is valued more as a commodity it will have more value as a recycled product as well. While giving a presentation recently, I made a statement about the fact that having programs such as Leadership in Energy and Environmental Design (LEED), which places a value on high recycled content in products, ends up creating a value for recyclable materials that did not exist before. This solution I think is more eloquent than my own of adding a deposit. Another side benefit is that this action is creating jobs at the local level because of the LEED emphasis on indigenous materials.
So I tip my hat to programs like LEED for helping to create local jobs, reuse local resources, and reduce the landfilling of valuable resources.
