IRDA developed the SHOCTM process to treat a variety of residual organic materials of agricultural, industrial, or municipal origin. This includes manure, crop residues, bio-solids, decomposable municipal waste, and other fermentable solids. SHOCTM is a closed-chamber biological treatment process that harnesses the heat generated by microorganisms to partially dehydrate and stabilize organic matter.

This process provides a solution that complies with Québec’s environmental regulations, which, starting in 2020, will prohibit the burial of organic matter.

SHOCTM is an industrial bio-drying or composting process that generates a partially dehydrated, sanitized, and deodorized final product that can be used beneficially as:

  • an organic amendment to provide soils with organic carbon;
  • a bio-fertilizer that supplies primary, secondary, and trace elements;
  • a dehydrated organic adsorbing material; and
  • bio-fuel.

An approach adapted to heavy annual rainfall and cold winter temperatures

  • Absence of leachates
  • Recovery of heat generated microbially

A patented and customizable made-in-Québec process and equipment

  • The process is designed to use heat produced by microorganisms under aerobic conditions.
  • A forced and controlled aeration system promotes the development of intense microbial activity, which, in a closed and isolated chamber, generates heat that quickly reaches a sanitizing temperature (>55oC) associated with the thermophilic phase.
  • The SHOCTM process can be used as a bio-dryer and/or composter, depending on the intended processing and treatment objectives.
  • A flexible annual processing capacity ranging from a few cubic meters to a few thousand cubic meters, depending on the number of modules.
  • The SHOCTM process has been patented in Canada and in the United States. The equipment patent is pending.

Features

  • Industrial process for treating residual organic matter that utilizes a modular design. This design allows for capacity adjustments to handle the annual tonnage of material to be treated
  • Closed-chamber process with a top feed, vertical flow, and evacuation of material from the bio-reactor base
  • No agitation system
  • A flexible easy-to-use automation system
  • Can be used under cover to treat organic matter continuously or in batches
  • Does not generate leachates

Licenses available

The SHOCTM bio-drying/composting technology can be used to dehydrate any solid organic wet matter, including residues or biomass generated by the food, forestry, agriculture, marine, and other industries.

IRDA is constantly on the lookout for companies wishing to enter into agreements to use the technologies developed by the Institute.

Organic residual matter from municipal sources

An exclusive license has been granted to Viridis Environnement to use SHOCTM technology for treating municipal organic waste.

Viridis provides a service for treating the organic fraction of household waste. Its processing chain includes the SHOCTM process to diverts tons of material from landfills.
