Product ecodesign and materials: current status and future prospects

The aim of this paper is to discuss the current status of ecodesign in the industry and its future implications for materials. There is today more and more focus on the environmental impacts of products during their whole life cycle. In particular, ecodesign aims at integrating environmental aspects during the product's design process as any other criterion, in order to reduce the life cycle impacts. Although a lot of product environmental impact assessment and Design for Environment tools already exist, environmental aspects are unfortunately rarely routinely integrated into product development process in the industry. This is mainly due to the fact that current ecodesign tools are little adapted to designers' practices, requirements and competencies. After the sequential and DfX paradigms, design of products is today maturing into Integrated Design, where multiple points of views and expertise have to be considered at the same time to progressively define the product

Integration of resource efficiency and waste management criteria in European product policies – Second phase. Report n° 1. Analysis of Durability

The present report aims at: 1) identifying key issues concerning the durability of products; 2) analysing methods and standards for the assessment of durability; 3) identifying potential product’s policy criteria for durability. The report is subdivided in 3 Chapters: Chapter 1 analyses scientific publications and standards to identify potential methods for the assessment of the durability of products. Also potential approaches to extend the operating time of products have been illustrated. Chapter 2 applies the method for the environmental assessment of durability to two exemplary washing machines. Chapter 3 illustrates hot spots for durability of washing machines, meaning those key components/parts that are functionally critical for the lifetime of the product. The analysis has been based on researches published in scientific literature and feedback from stakeholders. Potential environmental benefits for the washing machine product group due to extension of product’s lifetime have been also estimatedJRC.H.8-Sustainability Assessmen

Environmental Footprint and Material Efficiency Support for Product Policy - Feasibility study for a standardized method to measure the time taken to extract certain parts from an Electrical and Electronic Equipment

A study of the Joint Research Centre – JRC- on material efficiency published in 2012 established a method for the identification and assessment of “hot-spots” for End-of-Life (EoL) treatments of Waste Electric and Electronic Equipment (WEEE), including television, washing machines and imaging equipment. The method has been since then applied to various other product groups (e.g. enterprise servers). The improved extractability of target parts in Energy related Products (ErP) can represent a potential suitable requirement in the context of Ecodesign Directive for various product groups. In the case of measures for the “design for extraction of target parts in ErP” the 2012 JRC study identified the “time for the extraction” as a good proxy to prove the ‘easiness to disassembly’. However, the verification of the application of measures on extractability implies the availability of a method for repeatable measurements. The present report intends to provide scientific evidences on the feasibility of defining extraction times for the disassembly of WEEE and how it should be structured. The development of a standardised method for measuring the time for extraction of product’s target parts should allow the repeatability of measurements and minimizing uncertainty by removing or decreasing the influence of uncontrolled experimental conditions. The report includes a review of the relevant scientific references (including standards and scientific articles), discusses key issues for the measurement of the ‘time for extraction’ of product’s target parts and proposes how such keys issues can be integrated in an exemplary method for the measurement. Key definitions to be provided in the measurement method have been identified and provided for the following terms: target parts, extraction, extraction sequence, extraction time, worker experience, and tools for the extraction of components/parts. This report also establishes possible operating conditions such as testing area and safety requirements to extract parts of WEEE. The dismantling sequence has been identified as a crucial aspect. Detailed provisions on the dismantling sequence have been provided. The testing dismantling sequence has to be pre-defined prior to the product dismantling. Finally, a proposed measurement method has been developed as proof of concept and it is attached in Appendix 1. The method has been structured in order to reflect the framework of a potential international standard.JRC.H.8-Sustainability Assessmen

Environmental assessment to support ecodesign: from products to systems - A method proposal for heating systems and application to a case study

Different policy instruments at the macro and micro level coexist with the goal of reducing the energy consumption of the building sector. At the macro level, the Roadmap to a Resource Efficient Europe (EC, 2011c) and the Energy Efficiency Directive (EC, 2012a) highlight the importance of the building sector, which accounts for 40% of the total energy consumption in the European Union (EC, 2011a). Greater energy efficiency in new and existing buildings is crucial in order to reach the goal of the European Commission’s energy roadmap for reducing the GHG emissions by 80-95% by 2050 compared to 1990 (EC, 2011b). The implementation of the Energy Performance of Buildings Directive (EPBD) 2002/91/EC (EC, 2010b) promotes the energy efficiency in the heating, cooling, lighting and operating appliances and the use of renewable energy in buildings. In particular, Heating, Ventilation and Air Conditioning (HVAC) systems account for 50% of the total energy consumption of buildings (Pérez-Lombard, L., et al., 2008). In 2012, half of the EU’s energy consumption (546 Mtoe) facilitated heating and cooling, and much of this was wasted through insufficient insulation or inefficient equipment in buildings, among others (EC, 2016a). At the micro level, product policies such as Ecodesign and Energy Labelling Directives, EU GPP and EU Ecolabel have the common goal of making the EU market more sustainable. Indeed, they have been very successful in improving the energy efficiency of building products, especially those involved in HVAC systems such as water and space heaters, coolers or air circulators. However, even greater saving potentials could be achieved when the focus is done at the system level rather than at regulating products alone. The issue is that here are huge methodological challenges regarding the definition of systems, the scope and boundaries of a system, the modelling of components that make up a system and its interactions, and the measurement of the energy flows within the system. Policy makers have already recognised the limitations of considering isolated products instead of product systems, and have proposed to move these product policies from components to packages or groups of products (e.g Regulation 811/2013). This report provides guidance towards bringing closer micro and macro scale policies at the building sector. The objective of the work presented in this report is to explore the methodological aspects of environmental assessments of systems at the design step, in order to get higher environmental benefits. The procedure followed to develop the work of the present report began at analysing the system approach and environmental aspects at different product policies (Ecodesign and Energy Labelling Directives, EU GPP and EU Ecolabel) and the scientific literature (only on HVAC systems). As a result of this analysis and the comparison of both sources, some gaps were identified and general requirements were identified for a method supporting the design of good performing heating systems. Product policies usually apply the extended product approach to include additional products, part of the system, that influence the overall performance of a group of products (packages). However, the system approach, i.e. including all the components is not widely applied, as it should be. Product policies focus on environmental performances during the use phase, including energy efficiency, although other aspects can also be considered (e.g. air emissions, sound levels or other technical requirements). On the other hand, the scientific literature uses the system approach and holistic environmental assessment such as LCA. Then, the report proposes a simplified method and a calculation tool, to support the design process of good heating systems in residential buildings, based on the choice of the performance of its components. In the method, product performance figures provided by European sellers according to EU product policies are used when they are available. When product policy data is not available, designers are free to decide on which other tool to use to calculate the missing data. The method allows designers to study the improvement potential and combination of products’ performance levels and to achieve energy-saving targets at system level. The method provides two new aspects that are not yet covered by the literature: 1- it allows the assessment of heating systems grounded on well-known and proven labelling schemes such as EU product policies, which are available at the early design stage and implemented by all manufacturers, and 2- it supports design activities at system level, providing informed decision-making on multiple design solutions based on different configurations of products with performance levels currently available on the market. The method is also tested on a specific case study, simulating the re-design of two heating systems (a solar sanitary hot water system and space heating system) in a dwelling located in North Italy. The case study shows how the method can be applied using data of product policies when available, other tools and/or making assumptions. It also shows the quantitative results on the improvement potential of relevant components and on the combination of components with different performance levels. In addition, the package concept is applied to the case study. Despite the current limitations of the EU package concept (e.g. missing components and climate conditions, rough calculation, etc.), similar conclusions can be drawn from the EU package concept than from the method proposed, which shows the validity of the former. On the other hand, the method proposed is more complete, accurate and flexible and can therefore better support design activities. The method represents a step forward on how to address better the system approach in environmental assessments and how this could be applied to ecodesign of product’s systems. The report demonstrates that the method contributes at improving the task of building designers and regulators to easier achieve common and equivalent energy efficiency objectives.JRC.D.3-Land Resource

Collaborative network with SMEs providing a backbone for urban PSS: a model and initial sustainability analysis

iFirst 16 p.International audienceHigh-technology Small and Medium Enterprises (SMEs) have regularly shown their capacities for creating and developing innovative services. However, their reduced size often confines them to vertical applications and limits the possibilities for broader development. Strategies grouping SMEs into collaborative networks are possible but sometimes need a strong leader to ensure credibility. On the other hand, large integrator-operators cannot be proficient in all the necessary domains, particularly when applications move very fast. They very much need the diversity and the dynamics of these SMEs to provide service packages with a common service backbone. Uniting the different actors is a challenge displaying good promises from various perspectives including sustainability. However, it is necessary that the links between the different partners and their corresponding activities be correctly represented in a model to be understood. This article proposes a new model for activities and processes in firms collaborating together in a network. A clearer understanding of the organisation acquired with the model, which is then used to discuss sustainability issues within the network

Revision of methods to assess material efficiency of energy related products and potential requirements

The “Resource Efficiency Assessment of Product- REAPro” method has been developed to assess energy related products against a set of resource efficiency criteria, and to identify hot-spots and improvement potentials. The method has been applied and tested to various case-studies as: dishwashers, electronic displays, computers (notebook and tablets) and enterprise servers. These applications allowed to progressively refine the method from a scientifically perspective, but also to link the results to potentially new policy applications, including the development of new types of workable Ecodesign measures and Ecolabel criteria. The present report summarizes the recent advancements of the REAPro method and the definition of innovative requirements. In particular, novel elements discussed in the report are: - Analysis of benefits of reused components: The REAPro method only partially addressed the “reusability” concept (i.e. the potential full reuse of products at the EoL). However, it did not address the possibility that only certain key components (i.e. those having the highest residual value) could be collected from waste for the manufacturing of new products. This aspect has been addressed in a new method that allows to identify if, and to what extent, it is environmentally beneficial to reuse certain components for the remanufacturing of products (Chapter 2). In particular, it is observed that a product with reused components can still be environmentally convenient even if it has a higher energy consumption compared to brand-new products. The results of the method could be applied to build novel policy requirements, which allow higher energy efficiency thresholds for products that embody reused components. - Revision of the assessment of the index on recyclability: based on comments received by stakeholders related to previous case-studies, the index on recyclability benefit rate of the REAPro method has been revised to clearly separate the environmental impacts of the WEEE recycling from the potential credits due to the secondary raw materials produced (Chapter 3). - Assessment of the disassemblability and dismantlability of key components: design for disassembly of key components has been identified as a crucial aspect for the repair and recycling of the products. JRC has been working on developing suitable and verifiable requirements to assess disassemblability and dismantlability since 2012. These requirements have evolved, thanks to comments and suggestions from different stakeholders, and in particular from Market surveillance authorities of some Member States, which are in charge of verification of requirements. Two different types of requirements are presented and discussed in this report (Chapter 4): one based on numbers of disassembly steps necessary to disassemble certain components; and other based on criteria to grant the identification, access and extraction of key components for the product’s recycling, including requirements on their fastening and the provision of relevant information for the end-of-life treatments. - Recyclability of plastics: recycling of plastics is one of the biggest challenges in the WEEE treatment and is addressed in Chapter 5 of this report. Criticalities in plastic recycling have been analysed. In particular, large number of different polymers, technological barriers for plastic sorting, content of additives (especially flame retardants), difficulties for the extraction of plastic parts, downcycling and low value of secondary materials are among the reasons of very low recycling rates for plastics in WEEE. The reports therefore propose some potential requirements based on plastic marking and provision of information. A novel index on the content of flame retardants in plastic parts is proposed. Together with requirements on dismantlability, these requirements could contribute to improve the recycling of plastics from WEEE. At the time of the report (December 2016) several of the requirements above mentioned have been integrated and discussed in various policy proposals, as the Ecodesign requirements for electronic displays, enterprise servers and commercial refrigerating appliances, and Ecolabel criteria for computers and displays.JRC.D.3-Land Resource
