- Life cycle in practice: capacity building aiming European SME’sPublication . Pasquet, V.; Roy, A.; Adibi, N.; Coppee, S.; Echard, P.; Sousa Rocha, Cristina; Martins, Paulo; Alexandre, Jorge; Atin, E.The application of life cycle approaches – including life cycle assessment, ecodesign and environmental labelling – is becoming an increasing reality for business, and a growing challenge in many economic sectors. Businesses are facing increasing legal and market requirements to enhance resource efficiency and reduce the environmental impact of their products & services. To significantly address this challenge, the Life Cycle in Practice (LCiP) project was conceived, aiming to promote the uptake of LC approaches particularly in SMEs. The LCiP project helps SMEs in France, Belgium, Portugal and Spain reduce the environmental impacts of their products and services across the entire Life Cycle in three sectors: Buildings & Construction, Waste Management and Energy Equipment. LCiP’s specific objectives are to foster the widespread uptake of these approaches by SMEs beyond the duration of the project, by (i) Demonstrating the environmental and business benefits of applying LC Approaches through practical application in 32 businesses; (ii) Providing physical and online resource centres to support regional application of LC approaches; (iii) Building capacity for on-going implementation of LC approaches through a network of Life Cycle Champions and (iv) (Re)designing practical tools & methods tailored to the needs of the three industrial sectors. This paper presents the project's activities and expected results, as well as the conclusions of a maturity assessment on life cycle approaches that has been performed in the three sectors and four partner regions, as a means to identify needs and gaps that LCiP should fulfil.
- Pressure cooker under pressure: implementation of life cycle strategies and tools in a medium sized industry in PortugalPublication . Sousa Rocha, Cristina; Alexandre, Jorge; Camocho, David; Martins, PauloThis paper concerns the application of a set of life cycle oriented strategies and tools to a pressure cooker manufactured by a medium size company located in Portugal and targeting the international market. The life cycle assessment (LCA) indicated the major environmental problems of this product, which together with the company strategy of appealing the consumer through a 100% recyclable and more ergonomic product, provided the direction for the product and market development. Besides the LCA, an ecodesign project was carried out for a reference pressure cooker and through the use of several tools, including ecodesign checklists co-developed by LNEG in a previous project, a number of improvement options was generated, leading to the reduction and substitution of raw materials consumption, improved recyclability, better ergonomic features, more eco-friendly packaging and improved user interaction. A simplified environmental product declaration for the reference product was elaborated, in the framework of the EU Stepwise EPD project, and its marketing asset was evaluated through different communication methods, including phone meetings, website feedback, mailing lists and direct communication with customers in business fairs. This paper presents the results of this project and the characteristics of the improved product, and reflects upon the use of different life cycle-related strategies and tools in an integrated way; thus, this case study contributes to the understanding of the pros and cons of implementing life cycle strategies and tools in businesses.
- The hydrogen roadmap in the Portuguese energy system : developing the P2G casePublication . Cabrita, Isabel; Partidário, Paulo Jorge; Aguiar, Ricardo; Martins, Paulo; Rangel, C. M.ABSTRACT: The energy transition towards a decarbonized, energy secure and more sustainable economy is providing driving forces for significant challenges and opportunities on a country basis. It has been extensively argued elsewhere, that hydrogen (H2) is an energy vector having a strategic role in the energy transition as it enables to add value to the system, namely by: (i) Enhancing the flexibility of the energy system, through energy storage, service to multiple sources of demand and sector coupling based on power and gas grids; (ii) Integrating variable and intermittent renewable energy inputs in the National energy mix; (iii) Contributing to a holistic and innovation-oriented ecosystem.
- The hydrogen roadmap in the Portuguese energy system : developing the P2G casePublication . Partidário, Paulo Jorge; Aguiar, Ricardo; Martins, Paulo; Rangel, C. M.; Cabrita, IsabelABSTRACT: The planning and implementation of the Portuguese energy transition towards a decarbonized, energy secure and more sustainable economy is providing driving forces for significant challenges and opportunities on a country basis. The emergence of hydrogen (H2) within low-carbon pathways in the energy system requires to deal with the complexity of H2 carrier in its relationship with energy sources and end use sectors. In the frame of mainland Portugal energy system, different value chain configurations were analysed and assessed using energy analysis, lifecycle thinking and impacts assessment, as well as the technology and costs analysis, within an approach to the Hydrogen Economy. The Portuguese Roadmap for H2 was developed taking such an approach and therein the evolution of the selected value chains along time. Among these, ‘power-to-gas’ (P2G) combined with the gas grid is given an in-depth focus, as it was prioritized as the top value chain to answer the research question: how sustainable would be the hydrogen production and end use in Portugal within the P2G value chain? This P2G value chain with a particular focus on heating applications is discussed on the basis of the technology options and technology maturity identified in each main stage of the value chain, using analytical dimensions such as the energy efficiency and greenhouse gas emissions, among other impact categories, followed by a sensitivity analysis. The obtained results enable to show how case-sensitive that approach is and that a multi-decisional process is required to assist the planning stage.
