Municipal Biosolids

Sedron's Varcor® produces high-volume Class A biosolids at the lowest operating cost, with no capital investment.

The All-in-One Biosolids Processing Solution

Between environmental pressures, regulations, aging infrastructure, and unprecedented population growth, today’s municipalities are facing more waste processing challenges than ever before. Varcor, Sedron’s high-volume waste processing system, transforms these waste challenges into tangible benefits for all stakeholders involved.

The Varcor system helps municipalities solve their waste processing problems at a significantly lower cost per ton — without investment and without environmental tradeoffs. Whether deployed regionally or hosted at the plant, the Varcor is a highly advanced, compact, and surprisingly practical upcycling solution for municipalities across the country.

Patented, Game-Changing Technology

Sedron’s Varcor system converts biosolids and septage efficiently into clean water and pathogen-free, Class A dry and liquid nitrogen fertilizer without producing odor or greenhouse gas emissions, and with almost no landfill waste.

Let’s Talk

It accomplishes the work of multiple wastewater systems — dewatering, drying, and sidestream nutrient removal — using a single highly efficient technology that drastically reduces a municipality’s waste processing OPEX, CAPEX, and footprint.

Regional Deployment

As an integrated project developer, Sedron can provide the technology and in-house financing required to develop large regional biosolids facilities in underserved North American markets.

Wastewater Plant Hosted

For large wastewater treatment plants that seek an on-site solution, Sedron offers Design, Build, Own, Operate, and Maintain (DBOOM) and Design, Build Transfer (DBT) models under a tip-fee arrangement. With an unrivaled compact footprint, our Varcor system enables on-site hosting in facilities where such a solution was previously not feasible.

On-site projects allow Sedron to execute all dewatering, drying, and nitrogen removal at a significantly lower cost and without the operating challenges associated with multiple systems. This typically also allows facilities to achieve a 5X reduction in truck traffic.

One independent third-party report found that the Varcor system costs 60% less than conventional systems — and we pass these savings on to customers. With reduced investments and faster deployment, there’s a reason why more wastewater facilities are choosing Sedron’s Varcor technology.

Proven Waste Processing Benefits

From streamlined installation through maintenance, our municipality customers benefit from proven technology and turnkey support across the lifespan of their system.


No Capital Investment Needed

No Capital Investment Needed

With a well-funded capital structure, Sedron is strongly positioned to fund your projects. We have a track record of financing, manufacturing, and developing large-scale build-own-operate installations in underserved U.S. markets.

Reduced Biosolids Disposal Costs

Class A biosolids produced by the Varcor system significantly reduce disposal transportation costs. Their high solids content of 90%+ reduces unnecessary transportation volume caused by large quantities of water, which in turn decreases the number of trucks and/or frequency of trips required for disposal. The land application flexibility associated with Class A quality biosolids means that each disposal trip can be shorter in duration.

High Volume with a Small Footprint

High Volume with A Small Footprint

With a footprint of just 50’ by 200’, Varcor handles up to 150,000 wet tons annually. This capability is revolutionizing the industry.

Managed End-product Off-take

Sedron’s in-house agronomists handle all logistics and off-take management of Class A fertilizer and recovered nitrogen fertilizer.

Low Processing Risk for High-Strength Waste

Because it uses a thermal treatment system, the Varcor is less susceptible to biological or chemical upset conditions that require long recovery times. This makes the Varcor system a low-risk treatment solution for high-strength waste streams such as septage, leachate, and step loads.

Fewer Nitrogen Loading Issues for On-site Systems

The Varcor system’s patented process removes ammonia from the liquid input stream, resulting in an extremely effective method for solving nitrogen loading problems at wastewater treatment plants.
