Anaerobic Digestion
and Biogas
What is Anaerobic Digestion?
Anaerobic Digestion (AD) is an ideal circular organic waste management solution, creating valuable biogas from organic waste streams. Using a Combined Heat and Power unit (CHP), the biogas can be converted into renewable heat and power.
By using a biogas upgrading system, the biogas can also be turned into biomethane capable of fuelling vehicles or injecting into the Natural Gas grid to render Renewable Natural Gas (RNG).
Anaerobic Digestion Solutions by Convertus
As Canada’s largest and most advanced organic waste processor, we design and build AD systems based on our customers’ requirements. We analyze the waste streams to provide the optimal solution using wet Anaerobic Digestion, dry Anaerobic Digestion or a combination of both.
Why Choose
Anaerobic
Digestion
In addition to landfill diversion and the production of valuable soil amendments, Anaerobic Digestion has the potential to provide a sustainable, renewable and environmentally friendly green energy source.
With our Anaerobic Digestion technology you can add power and heat, or renewable natural gas to your product portfolio, for a ‘closed loop’ waste management system that literally powers itself!
Keep It Simple
Organic household waste is full of energy and ready to be re-used as a sustainable resource. The aim is simple: organic waste in, quality compost out and biogas out.
Household waste has a miscellaneous and undefined composition by nature. Our Anaerobic Digestion systems are designed to handle exactly that, without complicating the process.
Benefits of Dry Anaerobic
Digestion Technology
- No liquifying, mixing or pumping of the feedstock
- Foolproof and low maintenance
- Resilient to input fluctuations and feedstock contamination
- Modular design, scale up in phases
- Low operational cost
- No dewatering of digestate
- Seamless integration with in-vessel composting
- Batch tracking and batch reporting to prove permit compliance
- Seamless integration with liquid waste digestion
Benefits of Wet Anaerobic
Digestion Technology
- Wide range of feedstock/materials with high moisture content can be treated.
- More consistent feeding to the AD tanks.
- Higher biogas production
- Linear biogas production process
- Low initial investment required
- Low operating costs
- Natural biological desulpurization
- Less manpower required
- Digestate slurry can be pumped rather than loaded
Key Features
Tunnel System
The tunnel system is modular and perfectly compatible with in-vessel composting systems.
Each tunnel is equipped with a dedicated pre-fab skid that controls the tunnel process. This is connected to the central process computer. A central fermentation tank serves as the heart of the system and enables perfect integration with liquid waste streams.
Gas Engine
By means of a gas engine, the biogas can be turned into renewable heat and power. The biogas can also be upgraded to renewable natural gas serving the grid or fueling your own fleet of waste collection vehicles and other municipal transport. We guarantee a level of gas production based on the gas potential in the feedstock.
Digestate Composting
Dry Anaerobic Digestion has the advantage that the digestate does not need any dewatering and can be composted without any further pre-treatment. This leads to less handling costs and a better water balance than competing technologies.
Biogas
Turning organic waste into energy.
When you partner with Convertus, you can tap into the renewable energy potential of everyday organic waste materials in just a matter of weeks. Using compost starter, our anaerobic digester tunnels convert organic waste into Renewable Natural Gas (RNG). This gas is then used to fuel waste collection fleets and heat buildings – closing the loop for a sustainable future.
What is biogas?
Biogas is a natural by-product of the breakdown of organic materials by microorganisms in the absence of oxygen, a process known as anaerobic digestion. Most biogas consists mainly of methane and carbon dioxide, but the exact composition depends on what organic materials feedstock is used.
Biogas can be upgraded to natural gas standards, and/or used as renewable energy source to power homes or fuel vehicles.
Benefits of Biogas
Biogas is the by-product of waste treatment solutions for everyday organic waste.
Bottom-Line Savings and
ROI Using Biogas
Biogas production creates a true closed loop solution. Biogas produced can be immediately used onsite for combined heat and power (CHP) for the digestion plant itself. Biogas can also be used to power an engine, fuel cells, or gas turbines, producing electricity to be used on-site or fed into the national grid system.
Municipalities can save money on fuel costs to transport organic waste to landfills, and in turn power their vehicles using the biogas produced from the treated organic waste. Use of biogas as vehicle fuels reduce dependence on fossil fuels, and reduces greenhouse gas emissions compared to conventional gasoline or diesel.
