Proposal to Foster Sustainability through Circular Economy-Based Engineering: A Profitable Chain from Waste Management to Tunnel Lighting Molina Moreno, Valentín Leyva Díaz, Juan Carlos Sánchez-Molina, Jorge Peña-García, Antonio Sustainability Lighting Waste management Infrastructures Energy savings Raw materials CO2 emission Circular economy The increasing demands of infrastructures in terms of energy consumption, raw material demand, greenhouse gas emissions, waste management, treatment of components after their lifetime period, and financial costs are nowadays a serious threat for sustainability. Given that the resources are limited, it is difficult to ensure an accurate level of well-being for future generations. For this reason, new perspectives in design, production and consumption are necessary. In this work, the principles of circular economy are applied to concrete branches of engineering. Departing from a design orientated to new uses after life period of infrastructures, a circular economy-aimed engineering makes possible the connection and mutual profit of such different branches like waste management and tunnel lighting. The benefits in environmental and financial terms are a strong argument in favor of a stronger link between engineering and circular economy. 2018-01-23T10:56:53Z 2018-01-23T10:56:53Z 2017-12-02 info:eu-repo/semantics/article Molina-Moreno, V.; et al.
