A Closer Look at our Anaerobic Digesters


Wasatch Resource Recovery’s sister tanks fall nothing short of impressive. Each anaerobic digester is built to hold 2.5 million gallons of food waste, with the combined capacity to accept 1000 tons of food waste per day. Once operational, the digesters will produce enough biogas to power 40,000 homes – a town equivalent to the size of Bountiful. The capture and prevention of these greenhouse gases from reaching the atmosphere can also be compared to taking 75,000 cars off the road.

Structurally speaking, the tanks are not only impressive in size, but in their durability as well. The anaerobic digesters are expected to last for decades into the future, providing long term benefits to numerous communities along the Wasatch Front. While diverting waste from the landfill is an obvious perk, digesters also output several useful byproducts. Firstly, biogas captured during this process is a clean-burning renewable energy source that can be used to power homes and vehicles. Secondly, digestate can be used to produce bio-based fertilizer for use on local farms – providing a great alternative to chemical fertilizers that have the potential to pollute groundwater and soil. Finally, excess carbon can be used to grow algae; which can be dried and used as a bioplastic, to grow hydroponic crops, or even create energy. This system of recycling emulates the sustainable and cyclic natural systems we as humans rely on – and will stand as a hallmark of sustainability in Utah for years to come.

One Year Later, Where Are We Now?

Since breaking ground last June, Wasatch Resource Recovery has grown tremendously. What used to be empty land is now a collection of buildings including a chemical & dewatering building, a depackaging facility, a boiler building, hydrolysis, pressate, digestate and F.O.G. tanks, and of course, two digester tanks!

While the construction is rapidly developing, clients from across the Valley are signing contracts and committing to send their organic waste to the digesters. The support and enthusiasm from corporations, restaurants, grocery stores, and small businesses alike continue to perpetuate the progress of this project and its expected opening in late 2018. Before then, water tests will be conducted on the digesters, with test loads of organic material following soon after.

Anaerobic Digester Now Accepting Liquid Waste

The anaerobic digester project is moving forward!  In late August we began to introduce a few loads of liquid waste per week into the digesters. This was an exciting moment for us after a long development phase. We are currently accepting clean, liquid organic waste.  Examples of acceptable waste at this stage are brewery waste, DAF waste, and other types of food manufacturing byproducts or residuals.  These are metered into the digesters and used to create biogas and nutrient-rich biosolids.  Contact us today to find out how and when you can divert your liquid waste.

For other types of organic waste, (FOG, solid, packaged, etc.,) we are on track to finalize our project financing before the year’s end, which means we will be able to break ground on the new digesters in January of 2017.  We anticipate construction taking us into the fall of next year and being fully operational in late 2017.   Check back often to see how the project progresses.
