Applications for certificates of authorization and grants

Accredited characterization and sampling of materials

Viridis’ teams of agronomists, engineers and environmental professionals provide the expertise needed to prepare the applications for certificates of authorization and project notices required to manage residual material.

We also have the expertise to help applicants secure grants, for instance under PTMOBC, IRAP, NRC, NSERC, CRIBIQ, etc. programs, among other things to support R&D projects, by drafting protocols that are in line with current practices and regulations.

Applications for certificates of authorization and project notices for:
  • recycling FRMs in agriculture and forestry
  • setting up and running composting sites
  • setting up and running biomethanization sites
  • rehabilitating degraded sites (mining sites, sandpits)

Viridis is accredited for the sampling of fertilizing residual materials (FRMs) by the Centre d’expertise en analyse environnementale du Québec (CEAEQ) in regard to continuous and intermittent productions and for organic, inorganic and microbiological parameters.

This accreditation ensures that the sampling activities adhere to a strict framework of specific requirements yielding reliable results for numerous applications. It is an annual or semi-annual requirement for most FRM valorization programs in Quebec.

Viridis’ sampling establishes Ministry categories pertaining to chemical contaminants (C), pathogens (P), and foreign bodies (E). These classifications are used to determine the best means of valorization within the regulatory standards set out in the Guide sur le recyclage des matières résiduelles fertilisantes. The sampling applies to most types of residues, namely:

  • municipal biosolids;
  • pulp and paper biosolids;
  • compost and biomethanization digestate;
  • ashes;
  • lime residues from pulp and paper production;
  • slaughterhouse biosolids and residues;
  • agri-food biosolids;
  • downgraded milk, lactoserum and derivatives;
