Biogas Tanks


Biogas Tanks

Build worry-free Biogas tanks for less with Octaform’s corrosion resistant concrete forming systems.

Featured Project: Canada's 1st Zoo-Biogas Plant

Octaform partnered with Fitec Environmental Technologies Inc., a leading North American biogas design and engineering company to offer a packaged digester solution for the Metro Toronto Zoo. ZooShare will help turn the Zoo’s animal waste combined with food spoilage from local grocery stores into fertilizer and renewable power for the Ontario grid.

The combination of Fitec’s Self-Cleaning Digester and Octaform’s technology improves project returns by ensuring tanks remain free of grit accumulation and maximize plant uptime and performance while ensuring reduced risk and capital costs. Octaform tanks extend the facility’s service life and reduce ongoing maintenance and downtime requirements.

Build a Better Biogas Tank

The biogas produced by an anaerobic digestion plant is composed of combustible gases methane (50-75%), carbon dioxide (25-50%), water (H2O), nitrogen (N2), oxygen (O2 ), hydrogen sulfide (H2S), ammonia (NH3), and trace elements (organo-halogenated, siloxanes, etc.). H2S, CO2, and water make the biogas very corrosive.

Whether you’re fighting greenhouse gasses or the rising cost of energy, let Octaform help you build an anaerobic digester that will last. Octaform’s built-in PVC finish offers the best possible defense against the highly corrosive digestion process that will test the limits of any tank technology.


Build it Quickly with Octaform

Corrosion-resistance is just one reason to build with us. With Octaform, you can actually build a superior tank while saving money. It’s the only patented option that forms and protects your tank in one step. The finish and insulation are built-in, eliminating the need for liners or cladding. Our patented concrete forming system assembles quickly without specialized labor or heavy equipment. No cranes or steel forms are typically required. This alone often makes Octaform the most economical tank choice.

Build it to Last

In an anaerobic digestion system, cracks and leaks are not just a nuisance – they represent escaping profits. With Octaform’s built-in finish, you can stop worrying about corrosion, cracks and subsequent repairs. No need to expect downtime. Octaform outlasts any other tank construction technology.

Concrete is already one of the toughest and most long-lasting building materials on the planet – Octaform makes it better. Octaform systems have a built-in PVC finish that protects from corrosion, cracks, and leaks. It extends the life of the concrete and virtually eliminates the need for regular maintenance.

The digestion process is highly corrosive. Concrete sealants are expensive.

Concrete cracks result in gas leakage and lost profits.

Octaform stops corrosion and cracking from compromising your system.
