The University of Luxembourg developed the project upAM upcycling using Additive Manufacturing with the cooperation of FabLab Belval and Luxinnovation. This project was partially financed by Luxembourg National Research Fund Luxembourg (FNR). An alternative to a linear economy: extracting raw materials, producing, consuming, and discarding of a product, there is another option: Circular Economy (CE): reusing products, repairing, recycling, and upcycling. A concept of a system/process (upAM) is developed to reuse unwanted or un-functional polymers issued from existing products/ systems. Waste prints can be re-printed into new products or systems with the same / higher quality or value than products created from raw materials. The upAM project is, therefore, concentrating on upcycling according to the definition given by author” Upcycling is a process in which used materials are converted into something of a higher value and/or quality in their second life”. This definition is simple and reflects fully the meaning of the upcycling process. This idea is not new; the concept of reused materials/products giving them a new life has been present for hundreds of years as a countermeasure against the lack of raw materials. At the moment, the situation in developed countries is evolving. Society is more aware that unlimited consumption leads to unlimited production of waste. Therefore, collective consciousness of a circular economy occurs, which supports greater resources of productivity aiming to reduce waste and avoid pollution by design, and purposeful reused waste materials and unwanted products. Upcycling via additive manufacturing could be an important part of the circular economy (CE). Obviously, the CE and especially the upcycling process lead to reducing the usage of new raw materials, and it results in a reduction of energy usage, air and water pollution and even greenhouse gas emissions. The development of maker movement and democratisation of FDM technology is also strongly influencing the needs and benefits of the upcycling process. The project upAM is developed to increase this idea so that any individual can produce their products with a higher added value using recycled raw materials via the open technology of FDM 3D Printer.

Micro-cogénération à partir de biogaz: Modélisation et Rentabilité pour une PME Agro-alimentaire

L’optimisation énergétique des procédés de transformation constitue une des réponses les plus efficaces et adoptées face aux nouvelles contraintes européennes dans le secteur de l’énergie et de l’environnement. Ce travail présente comment la brasserie artisanale de Rulles (PME agro-alimentaire) peut, par une installation de biométhanisation couplée à une unité de micro-cogénération, faire de la dépollution de ses rejets d’eaux usées une production énergétique. Le bioréacteur aura comme matière première les eaux usées de la brasserie et produira du biogaz et des eaux quasiment non nocives pour l’environnement. Le biogaz produit servira de carburant pour l’unité de cogénération dont l’énergie produite sera réutilisée. Des unités de stockage tant pour la chaleur que pour le biogaz sont des éléments clés envisagés pour assurer un meilleur fonctionnement du système . Une telle installation remplira donc une double fonction : l’épuration des eaux usées d’une part et la production d’énergie d’autre part. [less ▲]
