This paper examines the ecological, technical, and economic aspects of using flint wastes extracted during the chalk extraction. The study presents the adverse effects of mining on the environment and draws attention to the mining waste generated. Flint wastes are proposed to be used in the crushed form as a substitute for high-quality aggregate for cement composites. Traditional concretes, which contained gravel and basalt aggregates in their volume, were used as control composites. Due to the satisfactory results of the technical tests, the described waste disposal method was also analysed in terms of possible economic benefits. Conclusions from the conducted tests proved that crushed flint waste is technically equal to high-quality special aggregates. At the same time, the costs of its acquisition and production in suitable deposition systems can be lower than the cheapest traditional gravel aggregates available on the market.
