A constant growth of interest in GSCM on the part of business practitioners creates a need to develop research within this field. One of the basic questions is why, despite numerous evidence of benefits resulting from the use of pro-environmental practices in supply chains, the level of GSCM implementations is low. Therefore, the aim of the paper is determining which barriers constitute the greatest obstacles on the way of GSCM implementation. The studies were conducted among Polish market entities. Therefore, they were prepared in the part of Europe in which there are not many studies regarding this topic. As a result of the conducted studies, it was determined that the greatest barriers for pro-environmental practices are included in the field which concerns knowledge and cost. What is more, the importance of particular barriers was specified in the paper.
The purpose of the study is presentation of the method of increasing the competitiveness of the mining industry through the demonstration of the possibility and potential in closing the loop of supply chains through waste management. A critical analysis of the source literature and an arithmetic analysis of statistical data in static and dynamic perspectives were accepted to be the research method. It has been found that the structure of the level of mining wastes and the level of their recovery rates demonstrate a large potential of closing the loop of chains in this industry and, at the same time, a potential to extend the chains through directing the material from recovery to various sectors. This constitutes an example of the direction of activities that are in line with the EU strategies for the economies of other states which possess this type wastes.
