DURABOT: THE TOOL TO INTRODUCE DURABILITY IN THE DESIGN PROCESS
Full text linkThe extension of the product lifecycle is crucial in the application of Circular Economy principles. However, when Energy Related Products are concerned, managing a durable product does not necessarily mean dealing with sustainable products. This happens because components and/or materials are affected by aging and lead to increased requirement of resources to run (i.e. electricity); there are certain trends that, although distinct from the previous facts, balance the effects of aging, i.e. energy grid mix decarbonization. In the present work an approach that considers both the economic and environmental consequences of durable products is proposed. The Durabot tool has been developed to accomplish the environmental analysis. The work overcomes the main literature criticalities: enables the assessment of environmental consequences of durability; the evolution of energy grid mix is introduced; the environmental consequences of durable products in different lifecycle scenarios can be assessed during the design phase; therefore, the components to substitute and to make accessible are identified. The tool is intended to be used aiming at design for product lifecycle extension, maintaining both economic and environmental convenience © The Author(s), 2023.

No full textN-protected 1,2,3,4-tetrahydropirydazines are readily obtained from the corresponding 1,2,3,6-tetrahydro-derivatives by double bond migration induced by ruthenium complexes. Almost quantitative conversions and complete chemioselectivities are achieved using RuCl2(PPh3)4 as catalyst precursor at 100° C in a pressure vessel. In the same conditions the cluster complex H4Ru4(CO)12 shows lower activity, while HRh(PPh3)4 gives unsatifactory results. © 1988
