Waste Partners

Deep geologic wells can be your dependable, secure waste disposal solution for challenging materials, including PFAS

Vaulted takes otherwise unusable organic waste and removes the headache of where it should go, locking it away deep underground—for good

Biosolids

Treated sewage is a fact of life. Not all of it can be landfilled or land-applied, and new challenges like PFAS are on the rise.

Paper sludge​

Our slurry injection process is perfect for high-water content materials so you can focus on other business needs.

Excess manure

Manure is an amazing fertilizer. We only take excess manure that isn’t in the right place at the right time for farmers to use. 

Agricultural residue

Ag byproducts are hard to use productively. We can take care of them for you and prevent emissions.​

Benefits for our waste partners

Improved economics over landfilling, land applying or other alternatives*​

Keep stakeholders and regulators happy by proactively getting ahead of PFAS and other environmental pollution issues posed by above-ground disposal​

Easier operational management of waste, including wastewater disposal

Improved strategic options for your customers

*dependent on factors like carbon content, distance from disposal well, counterfactuals, etc.

Case study

City of Derby, Kansas

2,400 wet tons of biosolids produced per year
Serves 26,000 residents
Working with Vaulted since November 2024

“Vaulted Deep has brought greater flexibility to our biosolids disposal operations. Their ability to manage disposal even during wet weather-when land application isn’t an option-has been invaluable”

– Dillan Curtis, Assistant Director of Public Works

How it works

Vaulted Deep takes 75% of the City of Derby’s biosolids from its municipal wastewater treatment facility

Vaulted uses its slurry-injection technology to sequester the biosolids in Class V permitted wells deep underground

Vaulted gives City of Derby an alternative disposal pathway for excess biosolids

Benefits

Safe alternative disposal of excess biosolids (biosolids that otherwise wouldn’t be land applied)

Lower cost compared to land
application

Greater operational flexibility for biosolids disposal (variable weather, conditions)

We take otherwise unusable organic waste. While “waste” isn’t a binary label, we define it as biomass that has little or no productive use in the context where it’s generated. If it’s landfilled, incinerated, dumped, or spread on land just to get rid of it—it’s unproductive. Evidence for that counterfactual is published on Isometric to verify its lack of value. 

Yes—but not all manure is usable, depending on the time and place. At many farms, excess manure builds up and becomes sludgy, contaminated, or logistically difficult to use. Vaulted targets this unusable portion, ensuring that its absence won’t lead to more synthetic fertilizer use or higher prices for farmers.

PFAS contamination is a growing concern for biosolid handlers, and land application is being scrutinized by both regulators and the public. Underground injection wells like Vaulted’s are now recognized as a reliable disposal pathway that prevents PFAS from entering the environment. Our slurry injection technology permanently isolates PFAS-contaminated waste deep underground. Read Lit Review

For most waste partnerships, we look for at least 1,000 tons per year. If we can co-locate a well with your operations, we aim to manage at least 20,000 tons annually. 

Highly moist, contaminated waste is expensive to landfill, incinerate, or otherwise dispose of properly. Vaulted offers more cost-effective disposal for this kind of challenging organic material. 

We inject waste into porous rock formations deep underground, surrounded by thick, impermeable rock above and below. This ensures containment for 10,000+ years—offering true permanent disposal.
