For Food Processors & Manufacturers

Your Byproducts Are Worth More Than a Tipping Fee.

Potato peels, grain hulls, off-spec product, processing residues: every load contains nutrients that came from the soil. WINR Centers turn your byproducts into natural fertilizer, cutting your disposal costs and giving your sustainability reporting something real to point to.

Sound Familiar?

The Byproduct Problem Keeps Getting More Expensive

Disposal costs keep climbing

Tipping fees and hauling rates go one direction. Every year, getting rid of byproducts costs more than the year before.

Wastewater surcharges add up

High-strength organics in your wastewater mean surcharges, capacity limits, and conversations with the city you'd rather not have.

Odor complaints find you

Stored byproducts don't stay quiet. Neighbors notice, complaints get filed, and suddenly it's a community relations issue.

Outlets come and go

The land applicator stops answering. The digester is at capacity. The farmer only wants it in spring. You need an outlet that’s there every day.

Sustainability reports need substance

Corporate wants landfill diversion numbers and a circularity story. "We sent it to a landfill" isn’t a chapter anyone wants to write.

Generator liability follows your waste

Your name stays attached to your waste stream after it leaves your dock. Where it ends up is still your problem.

None of this is your fault. Until now, there hasn’t been a better system. We built one.

The WINR Difference

One Outlet. Every Day. Documented.

WINR Centers were designed around generators like you: high volume, year-round, and accountable to someone for where it all goes.

Reduce disposal costs

In many cases cost-competitive with landfill hauling, with pricing that's predictable instead of climbing.

Beneficial reuse, not disposal

Your byproducts become inputs to a permitted nutrient recovery process, not landfill. That changes your liability picture and your story.

Reliable, year-round acceptance

We're not seasonal, weather-dependent, or at capacity. Your production schedule is our acceptance schedule.

Real sustainability metrics

Tons diverted, nutrients recovered, methane avoided: documented numbers your ESG reporting can actually use.

A local solution

Stop hauling byproducts hundreds of miles. WINR Centers serve generators within roughly 250 miles of Western Iowa.

Reduced generator liability

A fully permitted process with end-to-end documentation. You'll always know, and be able to show, where your waste went.

The Process

From Your Dock to a Farmer’s Field

We Assess Your Stream

Volume, composition, frequency, current disposal costs. No two waste streams are identical, so we design around yours.

We Handle Logistics

Pickup on a schedule that fits your operation. Transported to the nearest WINR Center. Documented end to end.

We Recover the Nutrients

Aerated Static Pile composting: controlled oxygen, temperature, and moisture. Consistent, high-quality output with lower emissions than traditional methods.

Farmers Put It to Work

Finished natural fertilizer goes to farms in our network. The nutrient cycle completes. Your waste built someone’s soil, and we can document it.

Who’s Behind This

“A waste stream is just a nutrient out of place. Mother Nature made all of it. We just need to put it back where it belongs.”

Abe Sandquist, Founder, Natural Fertilizer Services

This isn’t an experiment.

Abe Sandquist spent 20 years turning livestock manure from a liability nobody wanted into one of the most sought-after biological fertilizers in the Midwest. WINR Centers apply that same proven playbook to your waste stream, backed by a USDA Fighting for Producers and Entrepreneurs (FPEP) grant, two facilities underway in Western Iowa, and a third site already purchased.

Questions We Hear

What types of processing byproducts do you accept?

Organic byproducts from food and beverage processing: vegetable and grain residues, off-spec or expired product, DAF sludge and other organic residuals. We assess each stream individually and build a custom acceptance plan.

Can you handle our volume?

WINR Centers are built for industrial-scale streams: byproducts by the semi load, on a recurring schedule. Tell us your volumes and frequency and we'll tell you straight whether we're a fit.

What does it cost?

Depends on your stream: volume, composition, frequency, distance. In many cases WINR is cost-competitive with landfill hauling, and your costs become predictable. We'll give you a straight answer on a call.

Where are you located?

First two facilities in Western Iowa, serving generators within roughly 250 miles. Outside that radius? Reach out anyway. The model is built to replicate, and we're seeking partners in other regions.

How is this different from landfill disposal?

Landfills are a dead end: nutrients lost, methane generated. WINR Centers recover nutrients aerobically and return them to farmland. Your waste builds soil instead of filling a hole, and you get the documentation to prove it.
