Description
The development of public awareness of sustainable development is the first desired response to the overwhelming environmental impact of human activities. Understanding that industrial activities, such as mining and metallurgy, have so far favored mass production over a balance with natural resources is the first step in shifting toward concepts such as the circular economy. The concept aims to solve social, economic and environmental problems by proposing a transition from a linear economy model, defined by direct disposal of post-consumer goods, to multiple-use loops based on reuse, recovery and recycling characteristics of the circular economy. Development of sustainable materials that will enable closed loops to be introduced into production processes through opportunity using waste and by-products from different branches. Materials that respond to the needs of this model are, among others, geopolymers. The aim of the article is to show a case study of good practices in the area of implementation of a circular economy approach. This case study shows the possibilities of using mine tailings as raw materials for geopolymer productions and creating valuable products from them to use as building materials with additive manufacturing. The activities presented were carried the city of Lappeentanta, Finland.
