New project on greenhouse gas emissions

IVL has together with the Swedish University of Agricultural Sciences (SLU), JTI - Institute of Agricultural and Environmental Engineering and the Royal Institute of Technology (KTH) received a three-year grant from Formas and the The Swedish Water & Wastewater Association (SWWA) to study the formation and distribution of greenhouse gas emissions related to waste water treatment.

Nitrous oxide is formed when nitrogen removal, and also during storage and distribution of the  digested sludge on agricultural land. Methane gas can, except for during digestion where it is wanted, be formed during certain stages of water purification and storage of sludge before spreading. We will first identify the sources at different stages of the chain from water to sludge restored to agricultural land. The project will also compare some alternative treatments and it will suggest methods that reduce greenhouse gas emissions. Finally, we will carry out LCA analysis to check the overall environmental impact of the various treatment methods. That says Mats Ek leading IVL's part of the project.
