Design – Finance –Operate – Treat – Recycle: a turnkey solution for municipalities.

Municipalities face a dilemma when it comes to picking a strategy for recovering and treating organic materials generated in their territory. Which technology best fits their circumstances? How do you go about financing, implementing and running such projects? Allying a thorough understanding of the needs of the entities generating waste and the ones using them, Viridis proposes adapted, realistic and affordable solutions.

Take advantage of Viridis’ know-how to help your municipality and the whole province meet its GHG reduction targets!

VIRIDIS, a turnkey solution




Recycling or organic materials

SHOC Process

Viridis proposes to municipalities, RCMs and waste management bodies an innovative solution for the treatment and recycling of organic materials contained in household waste as an alternative to the classical approach of third collection and composting. This new fully organic treatment chain integrates the SHOCTM (Drying and Sanitization by Controlled Oxidation) process, and includes the opening of bags, sieving, bio-drying and organic matter recovery. It yields a quality, hygienic and partially deodorized organic sub-product that can be recycled as fertilizer for agricultural soil or for restoring degraded soils.

Performance :

  • reduces by 45% the volume of waste going to landfill sites;
  • produces a material that meets the quality requirements of a recyclable product for agricultural purposes; and
  • paves the way for the recovery of other recyclable materials still found in household waste.

Environmental benefits for all of Quebec :

  • reduces the number of collection trucks on the roads;
  • extends the useful life of landfill sites;
  • improves the GHG balance of municipalities in a viable way: every 10 tonnes of waste treated by Viridis offsets the annual GHG emissions of one car; and
  • maintains soil quality for greater productivity and better water retention through quality organic material.

Composting source-sorted organic fraction of waste

Large-scale composting or on-farm composting offers interesting options for the management of organic matter. Viridis is working with RCMs and municipalities on implementing technologies for the treatment of residual organic materials, including regional composting projects. Viridis also offers composting services on the farm for manure and fertilizing residual materials from different sources.

Biomethanization of Source Separated Organics (SSO)

Viridis and its partner, Énergère the leader in the implementation and operation of municipal energy infrastructures, are proposing dry process biomethanization for the treatment and recycling of SSOs. The advantage of dry-process biomethanization, unlike the liquid process, is that it can also treat garden residues, which make up a large proportion of organic residues in Quebec. The final product is then returned as agricultural fertilizer through the Viridis and La Coop network, in the interest of an environmental circular economy.

A win-win biomethanization project right down the line :

  • high solid digestion is a way to avoid four-way collection
  • the facility is developed, built and run by an experienced team, at no risk to the client
  • robust, economical and proven German technology, with more than 50 active sites around the world
  • typically, treatment capacity is between 25 and 100,000 metric tonnes of SSO per year per site
  • the system ensures optimal production of renewable natural gas (RNG) and recyclable digestate
  • a Category A compost can also be produced to meet the client’s requirements
  • the project meets current environmental standards
  • a solution for adequate odour management
  • maximum social acceptability: return organic matter to the ground after extracting the energy

Viridis specializes in the management of mineral or organic waste, offering both custom-made and turnkey solutions ranging from the transportation to the recycling of materials, all in accordance with environmental, cost control and agronomic principles.
