Braungart suggests another institution to reinforce patterns of recycling and disassembly: the "waste supermarket" which would be a centralized location where consumers could "de-shop" by returning used service products, including packaging. It would not be a dump site but a source separation depot. Unmarketables are products and materials which cannot be consumed or used in any environmentally sound way. They might, for example, be toxic products like used lead-cadmium batteries. Braungart recommends that they be safely storedat cost to their original producersin state-owned "waste parking lots" in perpetuityuntil such time as society found a way to safely dispose or use the products. This cost to producers would supply some pressure to create products which could either be recycled endlessly or, more likely, be made of more benign materials. Braungarts system was proposed as the core of a new kind of regulatory framework which would also incorporate other kinds of performance standards and product or substance bans. While this amounts to a radical change from current forms of regulation, it seems quite unlikely that current economic and technological potentials for sustainability and eco-development can be attained without substantive reform of this kind. To date there have been no comprehensive initiatives to implement an IPS, but the regulatory trend, particularly in Europe, seems headed in this direction. As noted earlier, the focus of EU regulatory policy has begun to emphasize consumption patterns, along with a greater focus (through Integrated Product Policy [IPP] and Integrated Chain Management) on product design as a preventative strategy.
