The RAVITA process is patented both in the EU and in the USA
Construction of a demo plant has been kicked off
The construction of a demo plant for the RAVITA process began at the Viikinmäki wastewater treatment plant in 2018.
Government’s analysis, assessment and research activities: By utilising wastewater we could reduce the use of artificial fertilisers significantly
It is possible to reduce the use of artificial fertilisers by up to a fourth in Finland if we could recycle phosphorus dissolved in wastewater to be treated for fertilising purposes. Phosphorus in wastewater comes mainly from urine. If, at the same time, we could increase recycling of manure’s phosphorus, we would be able to entirely give up phosphorus-containing artificial fertilisers in Finland.
RAVITA was chosen as Government’s Key Project
At the end of 2016, the Ministry of the Environment announced a call for key project applications where full-scale test targets were looked for, in order to implement treatment of sludge from wastewater treatment plants based on nutrient recycling.
The RAVITA demo plant presented by HSY was selected as one of the funding targets. With the help of the funding, a pilot plant is being constructed at the Viikinmäki wastewater treatment plant. The pilot plant helps to research the end product, i.e. production of phosphoric acid.
