Abstract:
|
The irregular occupation of the territory in Lagoa da Conceição, and the deficiencies on the
wastewater management system, impacted negatively the trophic state of the coastal lagoon. After the
wastewater overflow in Lagoa da Conceição’s Wastewater Treatment Plant (WWTP) the impact
increased. The overflow manifested the need for an accurate quantification of the impacts caused by
the WWTP. LCA (Life Cycle Assessment) it’s a recognized tool for quantifying environmental impacts
caused by a product/system. Thus, this article aims to discuss the application of WWTPs through a
critical review, establishing relations between the results found by these applications, and the use of
LCA in Lagoa da Conceição’s case. 03 lines of discussion were identified on the articles review: the
role of LCA in identifying critical spots and improvement opportunities in WWTPs, comparison
between conventional and alternative infrastructures, and the life circularity on WWTPs |
