BENEFITS OF AD BIOGAS PROJECTS

KERIDIS BioÉnergie
GHG Reduction

The agricultural sector accounts for close to 10% of total GHG emissions in Canada (government source)

KERIDIS BioÉnergie

Green energy generated from waste

KERIDIS BioÉnergie
Odour Reduction

Anaerobic digestion reduces odours by 50% to 98% (social acceptance)

KERIDIS BioÉnergie
Increased Profits

Fertilizer savings for partners and sharing of profits from RNG sales

KERIDIS BioÉnergie
Agricultural Biofertilizer

Production of a high agronomic value agricultural digestate biofertilizer

KERIDIS BioÉnergie
Circular Economy

The recovery of waste as energy and biofertilizer helps close the carbon loop

KERIDIS BioÉnergie
Local Jobs

Creation of local jobs with good working conditions

Dependence on Fossil Fuels

RNG will gradually replace fossil natural gas

WHY NOW?

In Quebec :

  • Strong political will to develop bioenergy sources to reduce GHG emissions
  • Regulatory requirement to inject 5% RNG into gas systems by 2025 and 10% 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
