The Journal of Resource Recovery (JRR) is a multidisciplinary, Open-access journal with completely Free-of-Charge publication policy. JRR welcomes contributions from research (experimental, modeling and simulation), which consider sustainable and promising technologies for resource recovery from liquid, gaseous and solid based sources. The journal emphasizes the high-tech approaches and recent progresses for sustainable and practical strategies for resource recovery. Priority is upon technological, engineering, environmental and economic aspects of specific resource recovery practices, such as reusing, recycling and recovery from a wide range of liquid, gaseous and solid resources as well as bio-wastes. International, national or regional contributions with focus at any level of research, i.e., from individual resources or technologies, are welcomed. Contributions should emphasize scientific, technological and methodological issues, as well as the discussion of environmental, practical, and economic implications of the accomplished research.
