IRP1, Eco-efficiency, second life, recycling, seeks to provide knowledge and tools to evaluate and to lower environmental impacts of architectured materials, from raw material extraction to final product. The effective benefits of the proposed strategies are quantified using life-cycle assessment (LCA). The experience in CEMAM in terms of material durability will help implement eco-design strategies. To this end, we organize IRP1 along three connected axes:
The eco-efficiency axis will focus on both materials and process efficiency. A first objective is to propose strategies to satisfy engineering challenges (namely sets of multiple property requirements) while using the minimum quantity of material and natural resources. A second objective will aim to limit the use of matter and waste production in particular in additive manufacturing (AM) techniques.
The second-life axis explore strategies for saving the architecturation value until the end-of-life of products. Here, the long-term objective is to retain as much as possible the efforts and energy already involved in architecturation of materials by their reuse in another life-cycle. To this aim, we will take advantage of ECOMARCH and CMTC SFs to provide effective de-architecturation processes to repair or repurpose products and to maintain as much functionalities as possible into the economical loop.
The recycling axis is devoted to the development of innovative recycling processes, with a focus on aqueous biphasic systems (ABS), in order to recover the greatest part of critical materials included in technological products formed by multifunctional architectured materials. More specifically, we will tackle fundamental studies aiming at a better understanding and control of ABS.
