Policy Measures

Packaging materials are one of the largest contributors to municipal solid waste generation. In this paper, we evaluate the material impacts of packaging policy in The Netherlands, focusing on the role of material efficiency (or waste prevention). Since 1991, five different policies have been implemented to reduce the environmental impact of packaging. The analysis shows that Dutch packaging policies helped to reduce the total packaging volume until 1999. After 2000, packaging consumption increased more rapidly than the baseline, suggesting that policy measures were not effective. Generally, we see limited attention to material efficiency to reduce packaging material use. For this purpose, we tried to gain more insight in recent activities on material efficiency, by building a database of packaging prevention initiatives. We identified 131 alterations to packaging implemented in the period 2005–2010, of which weight reduction was the predominant approach. More appropriate packaging policy is needed to increase the effectiveness of policies, with special attention to material efficiency.

Selection Of

Product architecture significantly influences environmental impact. Modular architectures aid manufacture and reuse, thereby reducing manufacturing-related impacts and diverting usable waste from landfills. In contrast, modular product architectures may also sacrifice product performance or lead to over-designed products. These side-effects can increase environmental impact. The Black and Decker Firestorm and G5 George Foreman Griddle were studied to uncover and understand the effects of product architecture on energy and material efficiency. Both products incorporate component sharing for fulfilling multiple functions and incur environmental tradeoffs as a result. Experimentation, reverse engineering, and life cycle analysis of these products were used to inspire a number of guidelines for green design of modular product architectures. Difficulties involved the design of interfaces and selection of components for shared modules.

From the view of material metabolism efficiency, resource productivity in Liaoning Province has been improved strikingly as well as the material metabolism efficiency and the material excretion efficiency. From 2006, the material consumption per GDP and the reducing speed of garbage output quantity are slowing down while the material metabolism efficiency is stepping into a gradually-improving period. The environmental impact model IPAT created by Professor Ehrlich has been used for calculating the changes of environmental impact these years. The result shows that environmental impact in Liaoning Province tends to raise gradually, so the task of lowering resources and environment pressure in the future is quite urgent and it is necessary to seek for a reasonable material resource configuration.
