From Legal Transplants to Sustainable Transition

Extended producer responsibility (EPR), which assigns significant responsibility to producers to take back their end‐of‐life products to create incentives for redesign of products with lower life cycle environmental impacts, has come to a crossroad facing a trade‐off between the original innovation‐oriented regime design and the cost‐efficiency challenges in practice. This is particularly true in its implementation in non‐Organization for Economic Co‐operation and Development (OECD) countries as they are trying to transplant the “best practices” from OECD countries, for there is increasing skepticism as to whether EPR is suitable for developing countries at all. As an important producer of electronic products and destination of electronic waste (e‐waste) flows in the world, China has been expected to play a vital role in the evolution of global governance based on the idea of EPR, either to create new ways for producers to perform their end‐of‐life strategies, or to reshape the mode of production and consumption with its fast‐growing market. However, the establishment of EPR in China has been long and full of difficulties. This article reviews the status and trends in the establishment of an EPR system for waste electrical and electronic equipment (WEEE) management in China. We use the framework of a multilevel perspective of transition theory in our analysis to characterize the complex interactions among various agents in the evolution of the Chinese system from initial innovation‐oriented design to the current efficiency‐oriented version. An ongoing research framework for evaluation of the EPR program in China is outlined as the research agenda in coming years.     

Business‐to‐Business Information Technology User Practices at End of Life in the United Kingdom,Germany, and France

Business‐to‐business (B2B) electronics account for a significant volume of the electrical and electronic equipment (EEE) put on the market. Very little B2B waste electrical and electronic equipment (WEEE) is reported as collected in the European Union (EU) in compliance with the WEEE Directive, which uses the policy principle of extended producer responsibility (EPR) to ensure that WEEE is managed correctly. This presents a barrier to parties looking for access to the waste. Company practice dictates the channels into which B2B WEEE flows following primary use. This article presents a study that engaged with company actors directly to get a better understanding of business information technology (IT) EEE asset management. Data were collected to determine the barriers current practice could present to the collection of B2B IT EEE at end of life and the implications of these for the development of policies and strategies for EPR. A questionnaire was developed and data were gathered from organizations in three EU countries—the United Kingdom, Germany, and France—stratified by size. Some notable findings were that there are several routes by which end‐of‐life B2B WEEE can flow. The recycling and refurbishment of B2B IT units at end of use was shown to be commonplace, but it is likely that these units enter streams where they are not reported. The actors disposing of their units did not have information on the management or disposition of these streams. It is concluded that to achieve the goals of EPR for B2B IT WEEE, the networks and the operational practices of these streams need to be better understood when developing strategies and policies.     

Strategic, Financial, and Design Implications of Extended Producer Responsibility in Europe: A Producer Case Study

Extended producer responsibility (EPR) legislation, making producers responsible for financing and organizing take-back and recycling of waste batteries, packaging, end-of-life vehicles (ELVs), and waste electrical and electronic equipment (WEEE), has been or is currently in the process of being implemented in 29 different countries in Europe following introduction of European Union directives. This article reviews the potential impacts of EPR for waste batteries, packaging, and WEEE on producers distributing products in Europe through a case study of Sony Computer Entertainment Europe (SCEE)—responsible for marketing and distribution of PlayStation products.
There are presently more than 250 producer responsibility organizations (PROs) established to meet EPR obligations in Europe, which contrasts to the single national recycling schemes founded in the late 1990s. SCEE estimates it avoided anetcostof €408,000 in 2005 by introducing competitive review of PRO services (against a total net take-back cost of €401,000).To meet increasingly extensive compliance obligations, SCEE has initiated new activities, with considerable implications for the company's legal, sales data administration, procurement, accounting, and product and packaging approval practices.
Considering the ultimate aim of EPR to establish economic incentives for improved product design, several significant political and practical obstacles are described from SCEE's case and industry situation. Although the principle of EPR is indeed interesting, its practical application in Europe may require refinement. Producers, given adequate support by policy makers, still have opportunities to develop new processes under the WEEE Directive to facilitate design for the environment.     

Implementing Individual Producer Responsibility for Waste Electrical and Electronic Equipment through Improved Financing

Under the European Union (EU) Waste Electrical and Electronics Equipment (WEEE) Directive, producers are responsible for financing the recycling of their products at end of life. A key intention of such extended producer responsibility (EPR) legislation is to provide economic incentives for producers to develop products that are easier to treat and recycle at end of life. Recent research has shown, however, that the implementation of EPR for WEEE has so far failed in this respect. Current WEEE systems calculate their prices according to simple mass‐based allocation of costs to producers, based on broad collection categories containing a mixture of different product types and brands. This article outlines two alternative approaches, which instead calculate charges for products sold by producers by classifying them according to their eventual end‐of‐life treatment requirements and cost. Worked examples indicate that these methods provide both effective and efficient frameworks for financing WEEE, potentially delivering financial incentives to producers substantial enough to affect their potential profitability and, as a likely consequence, the decisions relating to the design of their products. In particular they fulfill three important criteria required by the WEEE Directive: they can financially reward improved design, allocate costs of historic waste proportionately (on the basis of tonnes of new products sold), and provide sufficient financial guarantees against future waste costs and liabilities. They are also relatively practical for implementation because they are based solely on cost allocation and financing. Further research and investigation would be worthwhile to test and verify this approach using real‐world data and under various scenarios.     

Extended Producer Responsibility in the United States

Extended producer responsibility (EPR) is a policy approach that requires manufacturers to finance the costs of recycling or safely disposing of products consumers no longer want. This article describes the evolution of EPR policies in the United States, focusing on the role of states as policy actors. For their part, federal lawmakers have not embraced EPR policies except to remove some barriers to state‐level initiatives. In the two‐decade period from 1991 to 2011, U.S. states enacted more than 70 EPR laws. In addition, manufacturers have implemented voluntary programs to collect and recycle products, but those efforts have proven largely ineffective in capturing significant quantities of waste products. With the help of new coalitions of diverse interest groups, recently states have renewed efforts to establish effective EPR programs, enacting 40 laws in the period 2008–2011. Several state initiatives suggest a more promising future for EPR.     

Differences in Perception of Extended Producer Responsibility and Product Stewardship among Stakeholders: An International Questionnaire Survey and Statistical Analysis

Different perceptions of the concept of extended producer responsibility and product stewardship (EPR/PS) have tended to lead to prolonged policy disputes and have likely affected the design of EPR/PS policies. We therefore surveyed stakeholders’ perceptions of the concept of EPR/PS, including its aims, application, and rationales, and analyzed 376 responses with regression analysis and cluster analysis. The results clearly demonstrated the diversity in stakeholders’ perceptions and identified/confirmed several patterns between stakeholders’ perceptions and attributes. Concerning aims, our analysis showed that stakeholders from middle‐/low‐income countries placed more importance on proper treatment and waste reduction in EPR/PS policy, while those from Europe, North America, Japan, and the rest of Asia had different perceptions on seven aims of EPR/PS, especially for increasing collection and shifting responsibility to producers, and paid varying attention to upstream and downstream improvement (e.g., better product design and recycling, respectively). Our analysis also confirmed that respondents perceiving lack of capability of local governments regarding waste management advocated EPR/PS more and respondents positive about information acquisition put more importance on physical responsibility. The largest contributing variables to the perception of EPR/PS were 14 specific EPR/PS mechanisms/issues, suggesting that discussion about specific mechanisms of EPR/PS policy is a key if common and better understandings of the EPR/PS concept are to develop. The dominant rationale of EPR/PS agreed upon by the respondents was producers’ capability, but the concept of beneficiary bears was also supported by 58% of respondents, especially by national governments and North Americans. Finally, implications of the results for EPR/PS policy development were discussed.     

Thermodynamic rarity of electrical and electronic waste: Assessment and policy implications for critical materials

The strategic relevance of extracting raw materials from waste from electrical and electronic equipment (WEEE) in the EU is increasing due to value chain risks caused by geopolitical instability, accessibility of specific minerals, and decreasing reserves due to growing extraction rates. This article examines the quantities of so-called critical raw materials (CRMs) originating within WEEE streams from a depletion perspective. Presently, current recycling targets are based solely on mass collection and recycling rates. We examine the potential limitations of this approach using an exergy-based indicator named thermodynamic rarity. This indicator represents the exergy costs needed for producing materials from the bare rock to market. The case of Italy is used to explore the application of the indicator at the macro (national) and micro (company) level for the product categories “small electronics” and “screens and monitors.” Our estimations show significant differences between the mass and rarity of materials within Italian WEEE streams. While iron accounts for more than 70% of the weight of the product categories analyzed, it accounts for less than 15% of the rarity. Similarly, several CRMs with a small mass have a higher rarity value, for example, tungsten with less than 0.1% of the mass and over 6% of the rarity. The policy context is reflected upon, where it is argued that thermodynamic rarity can provide novel insights to support end-of-life WEEE decision-making processes, for example, target development and recycling standards setting to help prioritize material monitoring and recovery options.     

An Input‐Output Model of Extended Producer Responsibility

Under an extended producer responsibility (EPR) system, when a producer delivers a product to the market it must also pay a takeback fee, which is used to cover the costs of end‐of‐life disposal. EPR systems are currently used in Europe and beyond to manage a variety of products, including packaging and used tires. In this article we develop an input‐output (IO) model that is able to assess the impacts of an EPR system, and is based on the waste IO (WIO) model. The WIO model is itself a hybrid‐unit model extension of the Leontief model that is able to capture the substitution effect between recycled/recovered material/energy from waste treatment and their non‐waste cognates. The resulting EPRIO model, besides the conventional direct and indirect effects of the Leontief model and the substitution effects of the WIO model, is able to capture the opportunity costs of financing the EPR system, and additionally requires the specification of an alternative waste management policy, with its own opportunity costs. The impact of an EPR policy is thus the difference between the impacts of the reference EPR and the alternative waste treament policies. The resulting model is illustrated with a simple example of a used tire management EPR system.     

A Statistical Analysis of Prices of Electrical and Electronic Equipment after the Introduction of the WEEE Directive

In January 2003, the European Union (EU) issued a directive on e‐waste (waste from electrical and electronic equipment; WEEE) to deal with increasing quantities and the included hazardous components. The WEEE Directive is based on the principle of extended producer responsibility, which shifts the responsibility for end of life of products away from municipalities toward producers. This led some researchers to state that, in theory, the costs of waste treatment are passed on to consumers in terms of higher prices. This work addresses two fundamental questions: (1) Did the introduction of the WEEE Directive increase consumer prices of electrical and electronic equipment (EEE)? and (2) how much is this price increase? We carry out, for the first time in the literature, a quantitative research on price variation of the vast majority of EEE sold in the EU after the introduction of producers’ financial responsibility. The panel data include 972 price level indices, namely, six categories of EEE for 27 member states for six years. The main result is that the average variation of the prices for each category of EEE investigated actually increased and the variation was between 0.71% and 3.88%, depending on the specific category of EEE. The average increase of 2.19% is in line with the previous studies that estimated the impact of the WEEE Directive up to a 3% increase of the product price. The t‐test performed on the data shows a good statistical significance, which strengthens the relevance of the results. Finally, future directions for research are included.     

Operational Perspectives on Extended Producer Responsibility

We revisit three important assumptions about extended producer responsibility (EPR) that originate from academia, policy, or practice: (1) A central objective of EPR should be to induce product designs for the environment; (2) collective EPR implementations mute incentives to design for the environment; and (3) more stringent EPR policy parameters will generate better environmental outcomes. We discuss the potential shortcomings of these assumptions from an operations perspective and their implications for academic and policy research.     

Implementing Extended Producer Responsibility Legislation

The goal of this article is to contribute to the understanding of how the multiple, and sometimes conflicting, stakeholder perspectives and prevailing conditions (economic, geographic, etc.) in the implementation locality shape extended producer responsibility (EPR) “on the ground.” We provide an in‐depth examination of the implementation dimension of EPR in a specific case study by examining concrete activities at the operational front of the collection and recycling system, and probing the varying stakeholder preferences that have driven a specific system to its status quo. To this end, we conduct a detailed case study of the Washington State EPR implementation for electronic waste. We provide an overview of various stakeholder perspectives and their implications for the attainment of EPR policy objectives in practice. These findings shed light on the intrinsic complexity of EPR implementation. We conclude with recommendations on how to achieve effective and efficient EPR implementation, including improving design incentives, incorporating reuse and refurbishing, expanding product scope, managing downstream material flows, and promoting operational efficiency via fair cost allocation design.     

International Cooperation for Metal Recycling From Waste Electrical and Electronic Equipment

This article addresses a market‐based management concept for waste electrical and electronic equipment (WEEE) known as the “best‐of‐two‐worlds” approach. The concept is based on the idea that recyclers in developing countries and emerging economies can cooperate with technologically advanced refineries in industrialized countries to facilitate efficient recovery of valuable metals, such as gold and palladium, from e‐waste. The article provides an overview of technical and environmental concerns underlying the concept and sheds light on the political framework, the waste‐related trade issues, and the resource economics that need to be considered for further decision making. Building on this synthesis, I conduct a qualitative assessment of sustainability impacts of the proposed concept by analyzing two scenarios and their associated risks. The analysis suggests that, under certain preconditions, the best‐of‐two‐worlds concept could yield significant improvements in terms of management of hazardous substances, resource efficiency, greenhouse gas emissions, income generation, and investments into social and environmental standards. Generally, two potential implementation scenarios were identified: Whereas under Scenario 1 only WEEE generated within developing countries and emerging economies is managed through the best‐of‐two‐worlds approach, Scenario 2 additionally incorporates WEEE imported from industrialized countries. Although both scenarios can yield a variety of benefits, Scenario 2 might cause a net flow of hazardous substances from industrialized countries into developing countries and emerging economies, thus leading to less beneficial sustainability impacts.     

Dimensionality Reduction and Visualization of the Environmental Impacts of Domestic Appliances

There is an increasing worldwide concern about the problem of dealing with the waste electrical and electronic equipment (WEEE), given the high volume of appliances that are disposed of every day. In this article, an environmental evaluation of WEEE is performed that combines life cycle assessment (LCA) methodology and multivariate statistical techniques. Because LCA handles a large number of data in its different phases, when one is trying to uncover the structure of large multidimensional data sets, multivariate statistical techniques can provide useful information. In particular, principal‐component analysis and multidimensional scaling are two important dimension‐reducing tools that have been shown to be of help in understanding this type of complex multivariate data set. In this article, we use a variable selection method that reduces the number of categories for which the environmental impacts have to be computed; this step is especially useful when the number of impact categories or the number of products or processes to benchmark increases. We provide a detailed illustration showing how we have used the proposed approach to analyze and interpret the environmental impacts of different domestic appliances.     

End‐of‐life product management as a resilience driver for developing countries: A policy experiment for used tires in Ecuador

Over the last decades, a number of new environmental policies have been designed to improve waste management. Among them, extended producer responsibility (EPR) has introduced a mechanism to shift the environmental and financial burden of end‐of‐life products from public management to producers. Recently, EPR has been adopted by a growing number of developing countries, but this policy often struggles in being effectively implemented in such contexts, missing the opportunity of using waste management as a sustainability driver. By discussing the EPR for end‐of‐life tires (ELTs) in Ecuador, this paper proposes a different approach in designing and implementing EPR schemes in developing countries: it recommends consideration of social sustainability, rather than merely copying foreign management frameworks. To address this point, two case studies on socially directed ELT applications were designed and carried out. The case studies aimed at improving resilience of vulnerable populations to natural disasters by increasing the resistance of housing and settlements against catastrophic events using civil engineering applications. The analysis of the case studies’ outcomes brings to light possible policy adjustments, in which social sustainability goals are taken into account within the national EPR scheme. The Ecuadorian case also highlights the benefit of employing an adaptive governance approach when dealing with challenging urban management topics, such as informality (a widespread phenomenon in developing countries) and resilience.     

Extended Producer Responsibility for Waste Electronics: An Example of Printer Recycling in the United Kingdom

In February 2003, European Union (EU) policy makers implemented a Directive that will make producers responsible for waste electrical and electronic equipment at end-of-life (known as the "WEEE" Directive). Under this new legislation, producers are required to organize and finance the take-back, treatment, and recycling of WEEE and achieve mass-based recycling and recovery targets. This legislation is part of a growing trend of extended producer responsibility for waste, which has the potential to shift the world's economies toward more circular patterns of resource use and recycling. This study uses life-cycle assessment and costing to investigate the possible environmental effects of the WEEE Directive, based on an example of printer recycling in the United Kingdom.
For a total of four waste management scenarios and nine environmental impact categories investigated in this study, results varied, with no scenario emerging as best or worst overall compared to landfilling. The level of environmental impact depended on the type of material and waste management processes involved. Additionally, under the broad mass-based targets of the WEEE Directive, the pattern of relationships between recycling rates, environmental impacts, and treatment and recycling costs may lead to unplanned and unwanted results. Contrary to original EU assumptions, the use of mass-based targets may not ensure that producers adapt the design of their products as intended under producer responsibility.
It is concluded that the EU should revise the scope of consideration of the WEEE Directive to ensure its life-cycle impacts are addressed. In particular, specific environmental objectives and operating standards for treatment and recycling processes should be investigated as an alternative to mass-based recycling and recovery targets.     

Integrated Economic Equilibrium and Life Cycle Assessment Modeling for Policy‐based Consequential LCA

Consequential life cycle assessment (CLCA) has emerged as a tool for estimating environmental impacts of changes in product systems that go beyond physical relationships accounted for in attributional LCA (ALCA). This study builds on recent efforts to use more complex economic models for policy‐based CLCA. A partial market equilibrium (PME) model, called the U.S. Forest Products Module (USFPM), is combined with LCA to analyze an energy demand scenario in which wood use increases 400 million cubic meters in the United States for ethanol production. Several types of indirect economic and environmental impacts are identified and estimated using USFPM‐LCA. A key finding is that if wood use for biofuels increases to high levels and mill residue is used for biofuels and replaced by natural gas for heat and power in forest products mills, then the increased greenhouse gas emissions from natural gas could offset reductions obtained by substituting biofuels for gasoline. Such high levels of biofuel demand, however, appear to have relatively low environmental impacts across related forest product sectors.     

Charging up Battery Recycling Policies: Extended Producer Responsibility for Single‐Use Batteries in the European Union,Canada, and the United States

Extended producer responsibility (EPR) policies have proven effective at raising consumer awareness, expanding waste collection infrastructure, and shifting costs of end‐of‐life (EOL) management from municipalities to stewardship organizations. Yet, such policies have been less successful in advancing waste management programs that ensure a net environmental benefit. This article analyzes how EPR policies for single‐use batteries in the European Union (EU), Canada, and the United States address the environmental costs and benefits of EOL management. Considering these EPR policies is instructive, because single‐use batteries have high collection costs and are of relatively low economic value for waste processors. Without deliberate planning, the environmental burdens of collecting and recycling such batteries may exceed the benefits. This article considers how EPR policies for single‐use batteries integrate performance requirements such as collection rates, recycling efficiencies, and best available techniques. It argues that for such policies to be effective, they need to be extended to address waste collection practices, the life cycle consequences of EOL management, and the quality of recovered materials. Such strategies are relevant to EPR policies for other products with marginal secondary value, including some textiles, plastics, and other types of electronic waste.     

Adopting Lead-Free Electronics: Policy Differences and Knowledge Gaps

For more than a decade, the use of lead (Pb) in electronics has been controversial: Indeed, its toxic effects are well documented, whereas relatively little is known about proposed alternative materials. As the quantity of electronic and electrical waste (e‐waste) increases, legislative initiatives and corporate marketing strategies are driving a reduction in the use of some toxic substances in electronics. This article argues that the primacy of legislation over engineering and economics may result in selecting undesirable replacement materials for Pb because of overlooked knowledge gaps. These gaps include the need for: assessments of the effects of changes in policy on the flow of e‐waste across state and national boundaries; further reliability testing of alternative solder alloys; further toxicology and environmental impact studies for high environmental loading of the alternative solders (and their metal components); improved risk assessment methodologies that can capture complexities such as changes in waste management practices, in electronic product design, and in rate of product obsolescence; carefully executed allocation methods when evaluating the impact of raw material extraction; and in‐depth risk assessment of alternative end‐of‐life (EOL) options. The resulting environmental and human health consequences may be exacerbated by policy differences across political boundaries. To address this conundrum, legislation and policies dealing with Pb in electronics are first reviewed. A discussion of the current state of knowledge on alternative solder materials relative to product design, environmental performance, and risk assessment follows. Previous studies are reviewed, and consistent with their results, this analysis finds that there is great uncertainty in the trade‐offs between Pb‐based solders and proposed replacements. Bridging policy and knowledge gaps will require increased international cooperation on materials use, product market coverage, and e‐waste EOL management.     

High‐Resolution Insight into Materials Criticality: Quantifying Risk for By‐Product Metals from Primary Production

Many advanced energy and environmentally relevant technologies rely on metals that have been identified as critical, or whose availability may be limited. Several of these elements are produced mostly as by‐products of mining other base metals (carriers). This by‐product dependence has been proposed as a significant supply‐risk indicator by the materials criticality community. This article provides new quantitative evidence that, in several cases, by‐product metals’ availability may not be directly limited by carrier supply. We perform an assessment based on characteristics essential to by‐product metals, including physical concentration, market value of metals, and extraction technology efficiency. We analyze 40 carrier/by‐product pairs and identify five ‘high‐by‐product’ pairs. We assess the supply responsiveness of these metals. Our analysis suggests that rather than limited primary production of carrier, lack of incentive for improving recovery efficiency may limit availability of the by‐product. This behavior is found in the zinc‐indium and copper‐selenium systems. For germanium, on the other hand, we instead propose influence from the by‐product market itself leading to price inelasticity of supply. As a complement to other quantitative methods developed for material systems, such as material flow analysis, we provide an essential technoeconomic analysis of the by‐product metals problem by employing cluster analysis and econometric modeling. This approach provides insight into supply‐risk mitigation strategies related to extraction efficiency and supply‐chain structure.     

PTC Tasting and dental caries

Abstract

In the past decade, significant policy and legal changes have occurred that affect sexually active minors, pregnant adolescents, and adolescents who have become parents. This paper examines U.S. governmental policies and laws relating to (1) the development and dissemination of sex‐related health services and information for male and female adolescents and (2) the formal teaching of sex education in the public schools. It is maintained that despite the progress that has been made during the 1970's, a need for sex‐related services and information to the adolescent population still remains. Much remains to be done to formulate more relevant, effective policies and programs for adolescent males and females.
