INCOPA publishes an updated LCA study with IVL
IVL Swedish Environmental Research Institute has scrutinized the climate impact of water treatment coagulants, focusing on production processes, analyzing aluminum-based and iron- based coagulants and capturing carbon footprints in 2022.
Notable findings reveal cradle-to-gate carbon footprints ranging from 40 to 120 g of CO2 equivalents per mole of aluminum for aluminum-based coagulants and 40 to 70 g per mole of iron for their iron-based counterparts. Raw material production is the primary climate impact contributor. Secondary raw materials show reduced climate impact.
This research sheds light on the climate impact of coagulants, aiding eco-conscious decisions in water treatment.

Note that the value for PAC 10 (HB) had to be corrected. The revised versions were uploaded in October 2024.
