Biofertilizer

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

Green energy generated from waste

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

Fertilizer savings for partners and sharing of profits from RNG sales

Production of a high agronomic value agricultural digestate biofertilizer

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

Creation of local jobs with good working conditions

RNG will gradually replace fossil natural gas

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:

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

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