What is DfE?
DfE stands for Design for the Environment. According to its website, the program allows product designers to conduct an environmental assessment during the concept stage of design, where they can evaluate the impact of material selection as well as account for the end-of-life status of their product.
The analysis prompts designers to select from the DFMA database the materials they prefer to use or avoid, then reveals the proportions (by weight) of those materials in the product. It also estimates and designates the proportions of product that go to different end-of-life destinations, including reuse, recycling, landfill and incineration. Its ratings appear on such products as Zep, Green Guard and Clorox.
