This paper reveals the linear economy contribution to resource degradation and environmental pollution in eastern Romania that could further feed environmental crimes and conflicts, such as in the Pungesti shale gas case. Preservation of material and water resources in the region is required through various circular mechanisms under a cross-sectoral approach including solid waste as a material resource for industry and agriculture; wastewater treatment and water reuse; composting and organic agriculture; and using renewables. Six non-conflictual sustainable alternative routes related to circular economy mechanisms, water preservation, and to the clean energy transition are proposed in this paper, which are further examined through key statistics and indicators, current best practices, and local development pathways in both urban and rural communities.
