Our Biogas Plant

We turn waste into a resource

Our state-of-the-art biogas plant employs a process called anaerobic digestion. This utilizes naturally occurring microbes to breakdown organic matter, such as food waste and manure, to produce clean renewable natural gas and nutrient-rich organic fertilizer pellets.

Our biogas plant is good for the community, the economy and the planet.

Digester Feedstock

Dairy manure from our farm and neighbouring farms is pumped into digester tanks. Food waste is pumped into storage tanks (if clean), or tipped into a hopper (if mixed with non-organic material). From this hopper, using de-packing equipment, we separate the food waste from non-organic material (e.g., plastic, cartons, tin, paper, etc.).

We accept a wide variety of food waste (including food processing waste, supermarket and restaurant waste, spoiled food, green bin and residential waste, fats, oil and grease, animal feed, etc.) throughout the year.

Benefits

- Clean renewable natural gas

- Organic fertilizer pellets

- Reduced GHG emissions

- Food waste diversion

- Food and water safety

- Reduced odour

How it Works

The concept of an on-farm biogas plants is very simple; pump organic material, such as manure and food waste, into tanks with no oxygen and let microorganisms convert the material into renewable energy and a nutrient-rich by-product called digestate.

Essentially, there are four main operation stages of on-farm biogas plants:

1. Feedstock supply: this includes all types of organic waste, including

manure, food scraps, spoiled food, food processing waste, etc.

2. Biogas production: feedstock enters digester tanks where

microorganisms convert it into a renewable enrgy called biogas;

3. Biogas upgrading: biogas is cleaned by removing carbon dioxide

and hydrogen sulphide to produce renewable natural gas; and

4. Digestate management: once biogas is collected, the remaining

liquid digestate is spread onto fields, or made into organic fertilizer

pellets.
