Hazardous wastes were dumped in the most convenient fashion possible, ignoring possible environmental damage. Inefficient energy use resulted in high operating costs. Waste was common in material production, manufacturing and distribution. Consumers chose products, usually with only minimal re-manufacturing or recycling. Recognition of the above problems environmental engineering applications ME4211 Development of Green Products 2 inspired UPK / MECH Solution Strategies • Reactive strategies § End-of-pipe solutions • • § • Waste treatments Recycling Add-on solutions Proactive strategies § § Design for environment System changes for sustainability ME4211 Development of Green Products 3 UPK / MECH Products and the Environment • • • Environmental impacts from products are largely determined by the way a product is designed and produced - the material it is made from, its length of life, the nature of its use, whether it is designed to be recycled, and so on. The negative impacts can be eliminated/reduced by paying attention to them at the early stages of product design New direction for product design § § § § § Design for Environment (DfE) Eco-design Cleaner design Sustainable design Green design In this course the term ‘Green Design’ is used for the design approach that take into account environmental issues for product design.
