Holistic life cycle assessment of water reuse in a tourist-based community

摘要: Abstract Current trends point to tourism as a growing economic sector for many communities worldwide with possible environmental implications including water use. One solution these is reuse, which not only has been shown minimize potable consumption but also other impacts. Therefore, this study life cycle assessment of the impacts (carbon footprint, aquatic eutrophication, metals depletion, and footprint) four distinct management scenarios in Spanish tourism-dependent city Lloret de Mar. scenario business-as-usual where hotels are completely dependent water, while three (Decentralized, Hybrid, Centralized) integrate reuse (through varying degrees centralization) all located city. Results show that implementation incurs net carbon footprint impacts, there benefit associated marine eutrophication This mainly due treatment technologies used greywater/wastewater reuse. Comparing scenarios, an increasing degree centralization lower footprints. Finally, notable increase highlights importance indirect usage, case, hydroelectricity electricity mix well generalized scarcity issues within Spain.
