All OECD countries have developed and implemented waste prevention or minimization policies albeit differences among them. The term “waste” is reserved in this presentation, in general, for discarded products. The improvement on an existing policy needs proper consideration in any Guidance for new policies on waste prevention. There is need for a more complete evaluation since the benefits of the improvements will be incremental and the costs marginal for the additional amount of waste avoided. The number of policy options that have been devised for purposes of waste prevention is large. When considering improvements on existent waste prevention policies, there is need to factor in their evaluation the sustainability and eco-efficiency components. Unfortunately, in the early development and implementation of most of these policies these essential requirements were not factored. The reasons for the emergence of a new paradigm for environmental management at the private and public levels are many and discussed elsewhere. Any evaluation of improvements to an existent waste prevention policy should be conducted along the lines of the new paradigm. The concept of a national integrated product policy (IPC) is a more recent policy-oriented representation of the new paradigm. The concept has been gaining support in many countries in spite of the difficulties in framing the concept into policy and the needed flexibility in applying policy options. The presentation examines the problems and inefficiencies that would result in applying typical extended producer responsibility (EPR) policies such as “take-back” to specific product sectors where performance efficiencies are already very high. A case in point is transport packaging where voluntary waste prevention policies have achieved remarkable success. The issues associated with the imposition of “take-back” in this packaging sector are examined making use of tentative policy performance indicators.
