The results from these studies provided pivotal information about the efficiency of the elimination rates of the pharmaceuticals as well as the related costs. Importantly, they found that treating at the source reduced risks for groundwater and surface water bodies, and that it is possible to eliminate pharmaceuticals locally at the hospitals. This information proved the ability to mitigate these risks, and impacted plans for local treatment in the future.
Furthermore, the whole life cycle of the technologies was assessed to find out whether the advanced treatment caused environmental impacts at other points. In total, 50 papers and 130 articles were published concerning medical residues, decreasing the gaps of knowledge in this field, and increasing awareness of the problem in Europe.
After the end of the project, The PILLS partners continued their work in the follow-up project noPILLS, which focused on intelligent consumption of medicines and their proper disposal.
