The German Environment Agency has commissioned a project to study the effects of discharge water from exhaust gas cleaning systems (scrubbers) of ships on the marine environment. Scrubber discharge contains pollutants such as heavy metals and polycyclic aromatic hydrocarbons, which are classified as extremely hazardous. Discharge bans - at least regional - are recommended.
The reuse of treated waste water can help to reduce water shortages. Reused water can contain pathogens and harmful substances, however. On 28 May 2018, the EU Commission proposed a regulation, on minimum requirements concerning the reuse of water. It aims to protect health and the environment. The UBA considers there to be a need for improvement.
The use of treated wastewater, e.g. for agricultural irrigation, can alleviate pressures on water resources. At the same time it poses risks as treated wastewater can contain pathogens and chemicals. By May 2018 the European Commission wants to publish a regulatory proposal for requirements. UBA President Krautzberger and EU Parliamentarian Wölken invited for a discussion on 22 March in Brussels.
The EU Commission is seeking to adopt EU wide minimum quality requirements for water reuse for agricultural irrigation and groundwater recharge by the end of 2017. As the current draft falls short to set standards that are rigorous enough to protect the environment and human health, UBA has published a Scientific Opinion Paper to express its concerns and recommendations.
The waste water charge could be a viable way to help finance the upgrading of large waste water treatment plants to include a 'fourth treatment stage". A new study has determined that these facilities can reduce micropollutants – pharmaceuticals, for example – which are present in waterbodies.
Division III investigates a host of issues, including the following: How can production processes be made greener? How can natural resources be conserved?
