Special Issue Information

Dear Colleagues,

This Special Issue invites research articles on Advances in Life Cycle Assessment in Wastewater Treatment (WWT), an interesting and very useful topic that might be of great interest to the environmental scientist community as well as for the population in general. Wastewater treatment plants (WWTPs) are crucial for mitigating the impact of pollutants on water bodies. The transition to a more sustainable operation model requires increasing the system complexity; increasing recycling to save energy and raw materials; and minimizing emissions to the water, air, and soil. On the other hand, in the pursuit of more sustainable scenarios, the circular economy concept develops strategies and ideas for the treatment, processing, and reuse of waste, providing a second life, reducing the final waste to a minimum, and generating economic opportunities.

Thus, this Special Issue aims to attract new advances regarding the environmental assessment and the inclusion of circular economy philosophy in WWTPs. In particular, we invite proposals that discuss the principles, methodologies, case studies, and the integration of recent developments in LCA and environmental foot printing (EF) focused on WWTPs, as well as the integration of life cycle approaches with resource efficiency, circular economy principles, sustainability, and risk assessment.

All researchers working in the field are cordially invited to contribute original research papers or reviews to this Special Issue of Water.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Alternative wastewater treatment (WWT) technologies with lower environmental impacts seem to be the way forward in the pursuit of sustainable wastewater treatment plants (WWTPs). Process modelling of material and energy flows together with life-cycle assessment (LCA) can help to better understand these impacts and show the right direction for their development. Here, we apply this combined approach to three scenarios: conventional WWT; conventional WWT + chemically enhanced primary treatment (CEPT); conventional WWT + CEPT + side stream partial nitritation/anammox (PN/A). For each scenario, equations were developed to calculate chemical oxygen demand and nitrogen flow (solid and dissolved form) through the WWTP and to estimate the energy demands of its unit operations. LCA showed that the main environmental impact categories for all scenarios were global warming potential (GWP), eutrophication potential (EP) and marine aquatic eco-toxicity potential (MAETP). Compared with conventional WWT, CEPT and CEPT combined with PN/A resulted in a higher sum of normalized and weighed environmental indicators, by 19.5% and 16.4%, respectively (20.0% and 18.3% including biogenic carbon). Interestingly, the environmentally positive features of the alternative scenarios were often traded-off against other increased negative impacts. This suggests that further development is needed to consider these technologies a sustainable alternative. Full article
