About this Research Topic
Basic human needs such as housing, food and transportation require natural resources from around the planet. In our current system, which is based on linear economy, these needs are satisfied by extracting and processing resources and trading them for further manufacturing. However, materials and products lose their functionality after being used, ending up as waste often burned or land-filled. The concept of circular economy aims to overcome this linear economic concept of “take, make, dispose” by looping resources, which have lost their former need, back to the society. An increase in material productivity is achieved by elaborating various looping opportunities within the life cycle of materials. The development of materials and the improvement of their properties contribute greatly to Enhancing the circular economy. Where materials science can be used in several approaches such as recycling, developing green materials, and developing functional materials that have more than one use at the same time.
The Construction Industry is responsible for over 30% of the extraction of natural resources, as well as 25% of solid waste generated in the world. This happens because the construction sector mostly adopts a linear economic model of “take, make, dispose”, using materials to the construction of buildings and disposing them at the end of life, since they are assembled for one time use and don't retain potential for reuse. Over the last decades, a paradigm shift has been occurring in the industry at large, with the adoption of a Circular Economy model, that aims at keeping the materials in a closed loop to retain their maximum value, therefore with a greater potential of reducing the waste generation and resources extraction for the Construction Industry.
The goal of this Research Topic is to gather contents on the development of functional, green and sustainable materials which use less energy and provide a healthy and comfortable indoor and outdoor environment. Along with lower environmental impact, the targeted materials should be relatively low cost to run and in the long term, more valuable properties.
The Materials Circular Economy provides a platform for research related to the science, engineering and technologies of materials (reuse, recycle, redesign, re-manufacture, reduce, recover), life cycle engineering and life cycle assessment of materials. In the context of the above-mentioned problematic, a list of themes related to Materials Circular Economy reflecting the scope of this Research Topic are:
· Sustainable and green materials, life cycle engineering and life cycle assessment
· Highlights issues related to materials recovery and self-healing materials.
· Transforming waste material into a useful product with attractive properties.
· Development of novel materials from sustainable sources.
· Production and consumption, waste management and secondary raw materials.
· Functional materials and eco-design as well as methods to assess environmental impacts.
Keywords: Circular Economy, Sustainable Construction, Green Materials, Life Cycle Engineering, Waste Management
