Composting site

Since 1984, Fafard has been producing compost onsite that meets the standards set out by the Ministère du Développement Durable, de l’Environnement de la Faune et des Parcs (MDDEFP). Our compost mixes are recognized for their superior quality and comply with BNQ standards (type AA compost).

COMPOSTING PROCESS

In 2011, Fafard signed a contract with the City of Drummondville to collect food and green waste in order to make compost. The new composting site is located on two hectares of open space, and process ove 30,000 tons of organic material per year, a volume of 80,000m³.

Collect
Fafard receive few organic materials :

  • Solids residues such as manure and litter from the agroprocessing industry
  • Miscellaneous green residue
  • Municipal green residue
  • Softwood bark
  • Minucipal putrescible risude (3-pronged collection approach)

Sorting
Upon arrival at the Saint-Bonaventure site, the materials are sorted and placed into windrows to be turned into compost. Fafard diverts green waste from landfills.

Storage
Then, organic materials are stored under 100,000 sq.ft covered storage facility to protect from bad weather conditions.

Aeration

Also mixed in windrows according to predetermined formulas. A high-tech windrow turne ris used to bring in more oxygen, promoting the development of useful micro-organisms in composting materials.

For accelerated composting process ( forced aeration), the windrows are moved in composting tunnels where the compost is aerated for 2 or 4 weeks. Tunnel composting is a very efficient European technology allows our production continues 12 months/year, which substantially increases annual capacity.

Once mature, the compost can also be used to enrich soil mixes. Fafard therefore minimizes the impact of harvesting on peatland ecosystems.
