This paper analyses the problem of septage mining on islands in accordance with the circular economy (CE) concept. Islands are natural and socioeconomic systems wherein seasonal tourism and agriculture are the major economic activities, while environmental and health security are the top priorities. The majority of the individual housing facilities on islands are not connected to a public sewage system, thereby rendering the treatment and disposal of septage difficult. A significant degree of seasonal variability is observed in the quantities and characteristics of the septage produced, which hinders the sustainability of potential solutions. Consequently, there is a need to elucidate the benchmarks of a sustainable solution and quantify the CE implementation. This problem was solved using a simple two-step process. First, a concept for septage management was selected based on a waste hierarchy approach. Second, a sustainability policy was quantified by evaluating a composite indicator that accounts for economic, environmental, and social issues. The application of the sustainability index enables the assessment of the cumulative impact of the proposed solution on the environment of the island. The applied methodology has proven to be useful in the creation of a sustainable management concept that minimises negative impacts and protects resources. The proposed septate mining concept can strengthen the self-sustainability of islands and alleviate the threat to their business and environment.

This paper analyzes the problem of septage management on Croatian islands in accordance with the circular economy framework. The systems approach methodology has been used to analyze management issues. A large number of individual housing facilities on Croatian islands are not connected to the public sewage system. As a solution to the requirements of the competent services, holding tanks are used which are largely permeable. Due to tourism activities the amount of wastewater seasonally varies considerably and in summer is up to 10 times higher than in winter. Such a situation creates major problems for property owners due to mostly uncontrolled disposing of septage, which endangers the environment and human health. Although the situation is improving by application of EU directives, due to poor population density septage management will remain a permanent problem. The EU legal framework requires that organic waste be disposed of in accordance with the principles of a circular economy. This also applies to septage. It has been found that simple and robust options are sustainable and the best choice for a small island environment. After appropriate treatment, septage becomes a resource that strengthens the viability of living on the islands.
