Life cycle analysis approach to comparing environmental impacts of alternative materials used in the construction of small wastewater treatment plants

With the aim of reducing environmental burden decentralized wastewater treatment plants in India, this project investigated five primary materials (stainless steel (SS), mild (MS), glass fibre reinforced polymer (GFRP), high density polyethylene (HDPE), and concrete cement (RCC)) terms relative impact that each would incur across 13 midpoint 4 endpoint categories during early life stages. The results showed SS demonstrated substantially higher total (5.47 Pt) categories, most notably human health (3.12 Pt). Further investigations was largely fed by respiratory inorganics category accounted for 50 % (2.75 Pt), while global warming (0.93 non-renewable energy (0.70 terrestrial ecotoxicity (0.62 were only other considerable impacts. GFRP incurred second greatest overall (2.32 MS, RCC HDPE followed with 1.82 Pt, 0.78 0.39 Pt respectively. afforded efficiency all except carcinogens where least cost. Results then compared previous work likely causal factors highlighted. study is recommended to investigate longevity alternative a containment role support these results.
