Commitment summary
Nutrient recycling from wastewater sludge.
Kemira plays a significant role in the removal of nutrients from waste effluents from the Baltic Rim countries. The company commits itself to returning phosphorus and nitrogen, nutrients in wastewater sludge, to the natural cycle by introducing solutions that facilitate the safe recycling of nutrients into crop farming in the Baltic Rim countries. It also commits itself to influencing regulations and attitudes in favor of nutrient recycling.
Finland’s requirements for fertilizer products used in land improvement are among the tightest in the EU. The baseline of these requirements is that any land improvement substances used must be safe and beneficial to plant production. Substances added to the land must not burden our fields with heavy metals, nor may their runoff from agricultural fields cause eutrophication. Efficient supervision and authorization procedures prevent poor practices.

2nd Milestone
2010 November 02
Ratkaisuja fosfori- ja typpilannoitteiden kehittämiseen lietteistä
Kemira kehittää ravinteiden kierrätystä lietteistä. Tekesin Vesi-ohjelmassa mukana oleva hanke on osa Kemiran ja VTT:n perustamaa vesitutkimuksen huippuosaamiskeskusta.

Other activities within the commitment:
23 September - public awareness seminar in Riga on waste water update in Latvia organised by Kemira Oyj and BSAG.
Key subjects of the seminar were HELCOM Baltic Sea Action Plan, Latvian State commitment in progress, challenges and solutions in sludge handling by Latvian and Finnish stakeholders:

Eutrophication
Sludge disposal is a growing problem. Without their controlled return to nature, the nutrients in sludge can drift back and eutrophicate waterways, or accumulate in landfills. At present, artificial fertilizers are used in plant production, and their usage will continue in future. Forecasts indicate that, at current consumption levels, virgin phosphorus raw material will suffice for an estimated 70 years. Using BAT technology, the production of one kilogram of nitrogen requires 33-34 MJ/per one kg N. The ecological way to dispose of both nutrients, and the micronutrients contained in the sludge, lies in plant production.
The sludge product must be capable of enhancing crop production and it must be safe. Kemira’s concepts can influence the ratios and usability of phosphorus and nitrogen, allowing also sludge hygienization. Moreover, they enable the controlled pre-treatment of wastewaters from industrial facilities connected to the sewer network, so that the metal contents of sludge almost dwindle away. Strict regulations, supervision and attitude formation will dispel fears and prejudice related to the usage of sludge.
