After three years of working towards its ‘drive to zero’ landfill programme, DuPont Building Innovations claims to have reduced its annual environmental footprint from just over 36,000 tonnes of landfill waste to zero.

This means that all of the manufactured by-products, unusable raw materials, product scrap and construction debris generated by the manufacture of DuPont branded products such as weatherisation systems products and geosynthetic textiles are now being recovered.

This includes sanding waste which is being reused as a filler replacement in concrete, and crushed scrap which is sold on for use as road sub-base material and landscape material. In addition, shipping pallets are repaired, reused, or ground into animal bedding and carrier belt film is melted and used to make adhesives.

The project also included DuPont third-party partner sites, where products are often made for other companies. This meant that the project team had to manage the challenge of eliminating all unrelated product manufacturing landfill waste.

DuPont Building Innovation’s president Timothy McCann said of the achievement: “Working with our supply chain partners to tackle the zero landfill goal was critical to the success of our business in reducing its environmental footprint. Collaborating with our business partners allowed us to succeed in reaching our project goal.”
