Implementation of the Circular Economy in the Raw Materials Sector

Dear Colleagues,    

The global economy of raw materials depends both on changes in the structure and intensity of the demand for raw materials as well as their supply possibilities. Activities in the field of economic management of natural resources, and, at the same time, increasing the efficiency of processing processes and technologies for the production of secondary raw materials of waste origin, are gaining more and more importance.

The idea of a circular economy has breathed new energy into the raw materials sector, especially the part based on raw materials of waste origin, i.e., secondary/anthropogenic raw materials. However, despite many examples, the scope of using such materials is still insufficient.

In this edition, we would like to present examples of the most effective activities in line with the strategy of CE. They may concern examples of manufacturing high-quality products and their use in various sectors of the economy, in particular replacing primary raw materials. These can be experiments to expand the life cycle and use of raw materials by improving their properties or substituting potentially hazardous material with negative environmental impacts. Topics related to closing loops in raw material processing and increasing the efficiency of such processes are also important.

Often, the limited possibilities of using and reprocessing secondary raw materials are of a structural nature, the source of which may be legislation, previous practice or lack of trust of the stakeholders. Examples and methods of updating the prevailing framework in this area will also find a place in this topic.

Industrial waste landfills, as evidenced by frequent accidents occurring in recent years, are regarded as one of the most hazardous facilities in the world. For the adequate management of a landfill, risk assessments of dam failures should be performed before operations begin. This paper deals with the preliminary risk assessment used for the tailings and pyrite concentrate storage facilities, as well as the drainage waters reservoir, which are currently at the development and construction stage in the Cukaru Peki deposit located in eastern Serbia. The research was conducted to establish the facts and level of risk at an early stage to allow for timely prevention of potential accidents and bring operational practice in line with design requirements. The annual failure probability was estimated using a semi-empirical method, based on the dam stability factor. While, the framework proposed by the New Zealand Society on Large Dams was applied to assess the consequences of potential failures. The risk was assessed as a function of accident probability and the severity of possible consequences, and a 7 × 7 risk matrix was applied for analysis and evaluation. The level of dam failure risk at the location of the Cukaru Peki deposit was preliminarily assessed as moderate and conditionally tolerable, based on a low estimated probability of accident and a significant severity of consequences. Once the operation of these facilities starts risk assessments should be regularly updated, in order to maintain this level, and in accordance with the current situation, the modelling of specific accident scenarios should be included.
