Students are challenged to develop new products, or rethink them, to decrease the resource use intensity, giving priority to the use of renewable materials, including recyclable and/or bio-based materials, and with less hazard and risk (for humans and the environment) and reuse of materials. Students need to understand the importance of defining recycling, reuse, and life-cycle extension, considering possible useful applications of by-products and waste. Additionally, they need to pursue ways to attain more efficient and cleaner production models, producing more, at lower prices, with fewer resources, less waste and less impact on the environment.
