Recycling waste tires is a great business opportunity that benefits the environment, but can your market support a successful new start-up?

When it comes to tire recycling, it appears well-known that proper end-of-life tire (ELT) recycling techniques are utterly important for proper recovery of valuable materials and their reuse. However, it is equally important to: 1) Understand the life cycle of the end-of-life tire materials, 2) Assess footprint of different types of recycling / recovery on environment and quantifying and 3) Qualitatively and quantitively assess the effect that material and energy flows of a given product have on our communities, our planet, our health, economies, and the way we live. As a specialized consulting company, Weibold is competent in carrying out Life Cycle Assessment for circular economy concepts involving end-of-life tire recycling and pyrolysis products.
