Integration of Spent Quarries into the Circular Economy of Tourism: an Innovative Approach

Abstract

The purpose is to develop a scheme of industrial symbiosis of enterprises of different industries in the tourist area to create closed technological cycles, ensure waste-free and form new tourist sites through landscape rehabilitation of quarries using a fine fraction of limestone mining waste in biotechnological processes. Materials and methods. The study was conducted on the example of the resort city of Sochi using a systematic ap- proach and organizational and functional modeling. The scheme is based on the concept of a circular economy and the results of the study of innovative waste management technologies. Results and discussion. The prerequisites and problems of the formation of a circular economy of tourism are re- vealed. The scheme of industrial symbiosis of subjects of three industries has been developed: a spent quarry, small farms and a tourist enterprise, with a description of material flows. The model integrates biotechnologies for the disposal of lime- stone mining waste and agricultural production. The possibility of creating closed cycles that reduce the negative impact on the environment, support local agriculture and form new tourist products is shown. Examples of implemented projects of landscape rehabilitation of quarries are given. Conclusions. The proposed scheme provides economic, environmental and social benefits. It can serve as a basis for the development of sustainable and scientific- educational tourism in the areas of spent quarries, contributing to environ- mental safety and the development of a circular economy on the Black Sea coast of Russia.
