Naturally supportive of sustainable development, the Grap’Sud group recovers the co-products from its industrial processes for various agricultural uses within a circular economy approach.

These productions, which were traditionally reserved for the member co-operatives who wanted to see the organic matter returned to their soil, have since been developed and structured to be used in wider applications.

Composted organic amendments

Developed in an approach of return of organic matter to the earth, these natural inputs are composted for a minimum period of 6 months.­ They are mainly intended for environmentally-friendly agriculture and come in the form of a stable and homogeneous pulverulent mixture.

Depending on the matters used, we differentiate two products with distinct analytical profiles :

  • Generic organic amendment (NFU 44-095)­: standard product, with a relative N-P-K balance that makes it suitable for many crops.
  • Superior organic amendment (NFU 44-051)­: a relatively rich product (particularly in K), especially intended for vine-growing (usable in Organic Agriculture in accordance with Regulations EC n° 834/2207 and n° 889/2008).


  • Re-integration of organic matter into exhausted agricultural soils­
  • Improvement of the structure and chemical balance of soils
  • Balancing of the organic matter content for ornamental plants.


  • 25 tonnes in semi-trailer
