Product description

Characteristics of  digestates  in  general  are:  multi-nutrient  (N,  P,  K,..)    soil  improver  or  fertiliser  that  have  been homogenised, mostly hygienised (cfr EC1069/2009 (animal by-products)) and have a higher NRV compared to the initial feedstocks. The digestate of Agrogas is produced along a ‘vegetal’ line and an ‘animal’ (animal manure status) line. The digestate is separated into a liquid and a solid fraction. It must be kept in mind that the composition of digestate can vary depending on the flow of input materials that are digested. To give a representative view of value and variability of parameters a 30-percentile to 70-percentile range is given in this sheet – more specifically data spanning  3  years  of  sampling  &  analyses  on  digestate  product-types.  A  ‘vegetal’  or  animal  manure  status  liquid fraction with a dry matter-content of 3,5-8,5% – issue of the digestate passing a screw press – may be used directly or be further post-treated (MBR, RO and/or evaporation). Agrogas’ solid fraction digestate (with animal manure-status) – issue of the digestate passing a (‘sieve’ or ‘screen’) belt press – is usually dried until reaching a dry matter- content of 80-90%. In the new Fertiliser Regulation dried digestate can be categorized as PFC 1 A (solid organic fertiliser) or PFC 3 A (organic soil improver)(or in blend).  Prices for digestate can vary between negative prices  – depending on NPK- content  and  wether  or  not  the  digestate  has  a  animal  manure  status  (competition  with  manure  in  e.g.  Flemish region) and positive prices (35€/ton) for dried digestate with high dry weight (85-90%).
