WHAT IS ANAEROBIC DIGESTION?

A biological process whereby organic waste is converted into renewable natural gas and fertilizer.

Methanization process

BIOMETHANIZATION

A biological process that allows the conversion of organic residues into renewable natural gas (RNG), green energy injected into the gas network.
It fits into a sustainable development and circular economy approach.
Helps to reduce GHG emissions.
A sector encouraged by the Quebec government.

Inputs

Agricultural Family: Livestock effluents (manure and slurry), agricultural plant co-products (cereal chaff, corn stalks, straw, etc.)
Industrial Family: Dairy residues, fats, brewery residues, grain center residues, etc.

The Digestate

Increased fertilizing power (compared to slurry and manure) thanks to nitrogen mineralization.
Reduction of odors and pathogens through digestion.

Dependence on Fossil Fuels

Replacing fossil gas with GNR (goal of 10% GNR by 2030 in Quebec)

WHY NOW?

In Quebec :

  • Strong political will to develop bioenergy sources to reduce GHG emissions

  • Regulatory requirement to inject 10% RGN into gas networks by 2030

  • Introduction of financial incentives:

    • Grants for investments

    • Rising RNG repurchase rate

    • Compensatory carbon credit for anaerobic digestion of agricultural manure

In Canada :

  • RNG is part of Canada’s energy policy for reducing its dependence on fossil gas and greening its energy supply

Worldwide

  • Worldwide goal to inject 20% RNG into systems by 2050 according to the International Energy Agency
