Where Your Food Waste Actually Goes: Sheet Composting on Houston-Area Farms

Every hauler in Houston that offers “composting” is doing the same thing under the hood: collecting organic waste and trucking it to a facility. OnFarmCompost doesn’t. Your drum goes straight to a partner farm and is composted directly on the land it will feed. No facility, no truck back out with a finished product. That’s not a marketing line, it’s a checkable operational difference, and it’s worth understanding what it actually means.

What Sheet Composting Actually Is

Most commercial composting in the U.S. runs one of two ways. Windrow composting piles feedstock from many sources into long rows at a central facility, where it’s mechanically turned until it’s finished, then bagged or sold and hauled back out. In-vessel composting does something similar inside enclosed drums or vessels at a facility, trading open rows for more controlled conditions, but the material still travels in and the finished product still travels back out.

Sheet composting skips the facility entirely. Food waste and other organic material is layered directly onto the field it will feed, along with local carbon sources like wood chips, fallen leaves, or straw, and left to break down in place. The rows get turned, the same way a windrow does, but they sit on the farm itself instead of a processing yard, and the material never leaves that ground. After several months, it darkens into the same crumbly, earthy compost you’d expect from any well-run process. The difference isn’t the chemistry. It’s the location: the field the compost feeds is the same field it was made on.

The Method’s Origin

Founder Scott Sheridan didn’t start out in composting. In 2017, he started Scotty’s Fermented Foods, and running that business led him to ask what actually makes vegetables nutrient-dense. That question pulled him into regenerative agriculture and the study of living soil. There he came across the work of agricultural writer Sir Albert Howard, and Howard’s approach to sheet composting: apply organic material directly to the land where it will break down and build soil, instead of treating it as something to haul off and process elsewhere.

That idea, that food waste and manure are inputs for soil rather than disposal problems, became OnFarmCompost. Read the full story on the about page.

What Happens to a Drum After Pickup

The path is short and has no detours. A full drum is hauled from your business straight to a partner farm. It’s weighed at pickup, and the contents are applied and sheet-composted on that farm’s land. There’s no compost yard in between, no screening line, no bagging step. A standard compost yard has to windrow, screen, bag, and truck its product before it can sell at a retail markup that covers all of that overhead. OnFarmCompost skips every part of that chain, because the material never has to travel anywhere except the field it’s feeding.

Why the Compost Never Leaves the Farm

This is the question people ask most directly, usually as “can I buy your compost?” The answer is no, and the reason is structural. The compost is applied straight onto partner farmland as part of the sheet-composting process, and it stays on the land it’s made on. There’s no pile sitting in a yard waiting to be bagged and sold, because a yard was never part of the process to begin with.

What This Means for Your Diversion Reporting

Because every drum is weighed at pickup and every application happens on a known farm, your monthly ESG-ready report is built from actual measured weights, not modeled estimates. Diversion tonnage, methane avoided, and contamination rate all trace back to a real drum on a real scale, not an industry-average calculation applied to your covers count. If you’re reporting diversion numbers to a landlord, a certification program, or your own sustainability tracking, that’s the difference between a defensible number and an estimate you’d have to caveat.

What It Means for the Farmer on the Other Side

The same process that keeps your compost off the market is what makes it useful to a Houston-area farmer. Partner farms get a steady, weighed stream of food-waste feedstock delivered to their land instead of having to buy finished compost from a yard at retail markup. Much of the soil across Harris, Fort Bend, and Montgomery County is short on organic matter, and sheet composting builds it back in place, at a lower cost per yard than trucking in a finished product, because there’s no yard, no bagging, and no resale step anywhere in the chain.
