NPK Production Process

The document discusses EuroChem's nitrophosphate route for producing zero-waste fertilizers. This process, also known as the Odda process, integrates the conversion of phosphor from natural rock phosphate into a plant-available form while also utilizing all nutrient components to produce nitrate-containing straight and complex fertilizers. Benefits include producing high quality fertilizers without solid waste or emissions while saving money through utilizing own-produced lime. Challenges include potential exclusions of currently used raw materials from new fertilizer legislation that could hamper circular economy principles, as the Odda process exemplifies circularity through intrinsic design.

EuroChem’s nitrophosphate route to produce zero-waste


fertilisers

Description
Complex mineral fertilisers can be produced via various processes or production
routes. An important production step is the conversion of the phosphor from the
natural rock phosphate into a plant available form. One of the possible processes to
do so is called the nitrophosphate route or Odda process. The advantage of the
integrated Odda process is that not only the conversion of phosphor takes place but
also all nutrient components are used to produce nitrate containing straight and
complex fertilisers.

Added value
 Integrated process for production of nitrate containing straight and
complex fertilisers.
 All incoming raw materials are transformed into high quality fertilisers.
 No solid waste is created (as compared to phosphogypsum) and minimal
gaseous or liquid emissions.
 Replacement of mined dolomite or lime as filler by own produced lime, with
savings up to EUR 5 million per year.
 Consumption of CO2 gas from ammonia production.

Challenges
 Fertiliser production includes various examples of circular economy, but
depending on the interpretation of the Waste Framework Directive
2008/98/EC, a number of currently used raw materials in the production of
mineral fertilisers might be excluded from the list of allowed raw materials
(CMC1) in the new fertiliser legislation, even if REACH-registered, hampering
in this way the principle of circular economy.
 The Odda process is an example of intrinsic circular economic principles, and
has to be protected from misinterpretation of Directive 2008/98/EC or CMC1
definitions.
