Abstract

This study employs a life cycle assessment (LCA) methodology to evaluate the environmental impact of a paper mill wastewater treatment plant. Our investigation extends to comparing the eco-efficiency of utilizing biogas versus flaring it during wastewater treatment from Upflow Anaerobic Sludge Blanket (UASB) and explores the reuse of treated water within the production system. The ReCiPe (H) v1.13 method was applied to assess impact categories such as Climate Change, Ozone Depletion and Human Toxicity. The results showed a substantial reduction in environmental indicators by reusing biogas and treated water, highlighting the potential for sustainable practices in the paper industry. Transitioning from traditional methods to advanced technologies significantly lowers pollution indicators, aligning with global sustainability goals. Moreover, CO₂ emissions decrease fourfold when adopting innovative treatment technologies. These findings underscore the economic and environmental benefits of embracing advanced wastewater treatment, providing valuable insights for sustainable water management practices in the paper industry.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
