Fajardo, Tatiana Pinilla, Paula Bojacá, Viviana Pinilla Corzo, Rigoberto Ortiz, Jannet Acevedo, Paola 2019-07-26T14:23:44Z 2019-07-26T14:23:44Z 2016-04 6 p. Currently, reduce the environmental impacts generated by industries is vital; that is the reason why many companies are changing their processes to biotechnological processes which seem to be more sustainable alternatives. The Life Cycle Analysis (LCA) is an internationally accepted tool that allows environmental assessment of products and processes. In addition, LCA has been used to identify environmental improvement opportunities in different production systems and, that is the reason why it has been selected to be used on this research in order to diagnose the environmental performance of a Waste Water Treatment Plant (WWTP) of a cattle benefit plant. The system studied was a WWTP located in Cúcuta (Colombia), which treats 118.477 kg/day of water from cattle benefit plant. The stages of the WWTP are: screening, grit removal, primary sedimentation tank, homogenizer, grease traps, activated sludge reactor, secondary sedimentation tank, slow down flow filter and drying bed. In this paper the process diagrams and the mass and energy balances were constructed with information provided directly by the cattle benefit plant. The impact analysis was carried out using the software SIMAPRO 7.0 and the following impact categories were evaluated: climate change, eutrophication, photochemical oxidation, depletion of the ozone layer, acidification and biotic exhaustion. It was found that the environmental impacts of the WWTP of the cattle benefit plant are generated mainly due to the high electricity consumption in screening, homogenizer, and slurry reactor. Eutrophication was also observed due to the enrichment caused by the increase of the amounts of nutrients, which affected decomposition of excess of organic matter in the water so it could not be a complete mineralization of the nutrients it possesses. All the calculations were carried out using the Ecoinvent data bases. Favourable indicators were observed comparing the environmental profiles of the biological WWTP under study with the environmental indicators of a physicochemical WWTP of cattle benefit plant located in Bucaramanga (Colombia). The potential environmental impacts were lower in all the impact categories evaluated. application/pdf Fajardo T., Pinilla P., Bojacá V., Pinilla Corzo R., Ortiz J., Acevedo P., 2016, Life cycle assessment to identify environmental improvements in an anaerobic waste water treatment plant, Chemical Engineering Transactions, 49, 493-498 DOI: 10.3303/CET1649083 10.3303/CET1649083 978-88-95608-40-2 2283-9216 https://repositorio.udes.edu.co/handle/001/3468 eng Chemical Engineering Transactions Derechos Reservados - The Italian Association of Chemical Engineering, 2016 info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://creativecommons.org/licenses/by-nc/4.0/ https://pdfs.semanticscholar.org/e79e/69e48cb452e61cbbb00a6300a6b35ffacbd5.pdf Environmental Improvements Aerobic Waste Water Treatment Plant Life cycle assessment to identify environmental improvements in an aerobic waste water treatment plant Artículo de revista http://purl.org/coar/resource_type/c_6501 Text info:eu-repo/semantics/article http://purl.org/redcol/resource_type/ART info:eu-repo/semantics/publishedVersion Publication http://purl.org/coar/access_right/c_abf2 http://purl.org/coar/version/c_970fb48d4fbd8a85 |

Currently, reduce the environmental impacts generated by industries is vital; that is the reason why many
companies are changing their processes to biotechnological processes which seem to be more sustainable
alternatives. The Life Cycle Analysis (LCA) is an internationally accepted tool that allows environmental
assessment of products and processes. In addition, LCA has been used to identify environmental improvement
opportunities in different production systems and, that is the reason why it has been selected to be used on this
research in order to diagnose the environmental performance of a Waste Water Treatment Plant (WWTP) of a
cattle benefit plant.
The system studied was a WWTP located in Cúcuta (Colombia), which treats 118.477 kg/day of water from
cattle benefit plant. The stages of the WWTP are: screening, grit removal, primary sedimentation tank,
homogenizer, grease traps, activated sludge reactor, secondary sedimentation tank, slow down flow filter and
drying bed. In this paper the process diagrams and the mass and energy balances were constructed with
information provided directly by the cattle benefit plant. The impact analysis was carried out using the software
SIMAPRO 7.0 and the following impact categories were evaluated: climate change, eutrophication,
photochemical oxidation, depletion of the ozone layer, acidification and biotic exhaustion.
It was found that the environmental impacts of the WWTP of the cattle benefit plant are generated mainly due
to the high electricity consumption in screening, homogenizer, and slurry reactor. Eutrophication was also
observed due to the enrichment caused by the increase of the amounts of nutrients, which affected
decomposition of excess of organic matter in the water so it could not be a complete mineralization of the
nutrients it possesses.
All the calculations were carried out using the Ecoinvent data bases. Favourable indicators were observed
comparing the environmental profiles of the biological WWTP under study with the environmental indicators of
a physicochemical WWTP of cattle benefit plant located in Bucaramanga (Colombia). The potential
environmental impacts were lower in all the impact categories evaluated.
