- AV e PML: o seu contributo para a sustentabilidadePublication . Henriques, José João M. Silva; Maia, Anabela; Camocho, David; Rodrigues, Fátima; Alexandre, Jorge; Catarino, JustinaNo novo cenário de desenvolvimento, podendo a sustentabilidade entender-se como resultado da optimização de um processo multi-critérios num sistema complexo cujas dimensões básicas são a economia, a ecologia e a sociedade, novos desafios são colocados às empresas. Estas para aumentar o valor dos seus processos e produtos, terão que integrar na sua forma de gestão a tripla linha de base. Uma forma de operacionalizr essa resposta, passa pelo recurso a metodologias que as apoiem no seu percurso de eco-eficiência, como a Produçã Mais Limpa (PML) e Análise do Valor (AV). Lawrance Miles desenvolveu a Análise do Valor, nos anos 40, assentes nos conceitos de Valor e Função, como método para aumentar o Valor dos produtos existentes. As aplicações da Análise de Valor ultrapassaram o domínio dos produtos para abrangerem também outros domínios e deram origem a novas metodologias e técnicas de gestão que se desenvolvem com base naqueles conceitos. Este artigo mostra, passo a passo, uma metodologia - Valor Sustentável - desenvolvda a partir das sinergias entre a Análise do Valor e a Produção Mais Limpa, as fases de actuação propostas às empresas, desde a fase de orientação à decisão, os intervenientes em cada uma delas, as fichas de trabalho correspondentes e o tipo de rsultados que se podem obter. Será também apresentada a pertinência desta metodologia, fazendo-se referência a alguns resultados já obtidos em algumas empresas portuguesas.

- Footprint analysis of circular economy practices in the steel industry [Resumo]Publication . Sameer, Husam; Knoblauch, Lukas; Dürr, Hans H.; Flörke, Martina; Ambaye, Teklit G.; Lima, Ana Teresa; Mao, Ruichang; Lu, Zheng; Kunther, Wolfgang; Slabik, Simon; Hafner, Annette; Aloini, Davide; Zerbino, Pierluigi; Mabroum, Safaa; Ram, V.; Barbosa, Juliana; Simoes, Sofia; Genovese, AndreaABSTRACT: Steel is one of the dominant materials in the building industry, however, substantial environmental impacts occur in its supply chain. We evaluate the environmental performance of different steel production scenarios at the macro level, taking into account circular economy practices. Using the dynamic life cycle assessment methodology, different scenarios are assessed for the time horizon 2015 to 2070. The environmental footprints are quantified in terms of primary energy, greenhouse gas (GHG) emissions, material, land and water footprints. Forecasts regarding the availability of end-of-life steel and future demand in European and global contexts are considered.
- From need to manufacture: the design process in sustainable value approachPublication . Alexandre, Jorge; Maia, Anabela; Camocho, David; Rodrigues, Fátima; Catarino, Justina; Henriques, José João M. SilvaIn a sustainable development paradigm there must be a direct influence and a social responsible relationship between user, designer, and manufacturer. The different stakeholders interactions should be based on a dynamic influence of their needs. The challenge is to understand those needs, translate and monitor them through life cycle of products processes. The use of Value Analysis method (namely functional analysis, main phase of that methodology) and its integration with Cleaner Production, allows the development of a methodology that helps the definition of stakeholders needs and their transposition to the design, manufacturing and use phases. Due the functional approach, without techical solution in the problem definition, this kind of analysis should stimulate the criativity and the innovation. In this metodology the study subject is defined in terms of functions, quantified with technical, environmental and social criteria, in order to create a true dialogue platform between who orders and the designer, manufacturer or supplier. This approach enables to adjust either the evolution of the diffrent needs and the objectives to be attained. For the development of the work, namely the designer's one it is very important that since the beginning of the study the main objectives and constraints are defined. All this work is made by multidisciplinary team with people representing the main areas related to the study subject. The methodology allows the quantification of the functional performance (taken into account technical, social and environmental aspects) of a study subject and also all the costs related with materials, water, energy and human resources. The relationship between them will allow to quantify the Sustainable Value. In this paper we present the theoretical structure of the developed methodology and also its main results in several case studies.

- How far can circular economy practices contribute to a carbon-neutral Europe? The case of flat glass production in the construction sector [Resumo]Publication . Barbosa, Juliana; Simoes, Sofia; Aloini, Davide; Zerbino, Pierluigi; Mabroum, Safaa; Montalbano, Giammarco; Lima, Ana TeresaABSTRACT: The construction sector heavily relies on non-renewable resources for energy and materials. Addressing this, Circular Economy (CE) is frequently suggested as a means to foster sustainable growth while reducing global emissions. Yet, the actual impact of CE in the long term is still uncertain due to limited empirical evidence and various factors that may hinder its widespread adoption. Indeed, the transition to CE might necessitate a substantial transformation in production capabilities, supply chain modifications, the phasing out of existing capital, and investment in new technologies and facilities.
