TLDR
TF had the smallest environmental impacts and that AS had the largest, while HRAAD was in between the two but with much reduced impacts compared with AS, and shows that lower sludge production is the greatest advantage of HRAad for reducing environmental impacts.About:

Environmental and cost life cycle assessment of different alternatives for improvement of wastewater treatment plants in developing countries.
TL;DR: According to the economic evaluation, the addition of tertiary treatment leads to gain financial profits due to the value of the reusable produced water, and underlines the importance of considering LCA in development of WWTPs in developing countries.

Techno-economic and life cycle assessments of anaerobic digestion – A review
TL;DR: In this article, the authors present a review of the knowledge gap in technical feasibility, economic viability, and environmental sustainability of anaerobic digestion processes in terms of technology, economics, and environment.
Journal ArticleDOI
Life cycle assessment of upgrading options of a preliminary wastewater treatment plant including food waste addition.
TL;DR: Results showed that the baseline scenario had worse performance than all future scenarios except for climate change and the scenario of adding food waste to wastewater has the best performance in climate change, terrestrial acidification, terrestrial ecotoxicity and fossil depletion.

IMPACT 2002+: A new life cycle impact assessment methodology
Olivier Jolliet,Manuele Margni,Raphaël Charles,Sebastien Humbert,Jérôme Payet,Gerald Rebitzer,Ralph K. Rosenbaum +6 more
TL;DR: The IMPACT 2002+ method as mentioned in this paper proposes a feasible implementation of a combined midpoint/damage approach, linking all types of life cycle inventory results (elementary flows and other interventions) via 14 midpoint categories to four damage categories.

TRACI the tool for the reduction and assessment of chemical and other environmental impacts
TL;DR: TRACI as discussed by the authors is a stand-alone computer program developed by the U.S. Environmental Protection Agency, which facilitates the characterization of environmental stressors that have potential effects, including ozone depletion, global warming, acidification, eutrophication, tropospheric ozone (smog) formation, ecotoxicity, human health criteria-related effects, humanhealth cancer effects and human health non-cancer effects, fossil fuel depletion, and land use effects.

Life cycle assessment of wastewater systems : Influence of system boundaries and scale on calculated environmental loads
TL;DR: In this article, the authors compared the environmental loads from wastewater systems with different technical solutions and found that the separation systems outperformed the conventional systems by showing lower emissions to water and more efficient recycling of nutrients to agriculture, especially of nitrogen but also of phosphorus.
