📄 Abstract（原文）
The practical application of life cycle analysis contributes to the creation of more efficient, green technologies, such as the use of renewable energy – photovoltaic panels – in industrial wastewater treatment processes. Life cycle assessment allows for the comparison of CO 2 emissions and renewable energy consumption in wastewater treatment flocculants to identify the most environmentally friendly solutions using polymer flocculant – sodium salt of sulfonic acid derived from phenol-formaldehyde resin waste. The results of the research into the environmental impact of a new generation of polymer flocculant synthesized from phenol-formaldehyde resin waste con - firmed that this is the right direction for research, as it is ecologically justified. The aim of the study was to assess the life cycle of a flocculant synthesized from phenol-formaldehyde resin waste (novolak T) using energy obtained from photovoltaic panels. The environmental life cycle assessment was performed using SimaPro Developer v9.4 software, applying the Environmental Footprint (EF) 3.0 method and ecoinvent datasets. The functional unit was 100 kg of sodium salt of the sulfonic derivative of novolak T. The characterization results indicate a climate change impact of 170.1 kg of CO₂ equivalent and an acidification impact of 5.99 mol H⁺ equivalent per functional unit. The greatest negative impact on the environment is the production of sulfuric acid and sodium carbonate used to obtain sodium salt of phenol-formaldehyde resin sulfonated derivative. Recycling novolak waste results in negative results in the analyzed impact categories, including resource use and fossil fuels (−5.02 × 10³ MJ). Recycling has a positive impact, and the overall results indicate that in the supply chain and reagent consumption in the quarter-technical scale production process, it is the main factor reducing the environmental footprint of the polymer-flocculant derived from waste.
