Compost pelleting is one of the more approachable applications in pellet production — when the material is right. Consistent moisture, manageable particle size, and good flow characteristics make compost one of the easier materials to feed and pellet reliably. The key is understanding your specific material before you design the system around it.

Unlike some materials where moisture can be managed through blending and system design, compost moisture is highly dependent on the source material and how it was processed.
Some compost materials arrive at a consistent, pellet-ready moisture level. Others require drying upstream before the feeding system can do its job effectively.
3MT designs compost feeding systems around your specific material's moisture range and behavior — not a generic compost assumption. If your material needs upstream drying we'll tell you that upfront before any equipment is specified.
A local compost operation came to us looking for a practical, cost effective way to get into pellet production. Rather than specifying all new equipment we helped them build a functional pellet mill line using quality used equipment sourced at auction — keeping their initial investment lean while still delivering a reliable production system.
The feeding system was built around one of our PSM feeders. The operation ran well and the customer was able to load the PSM directly — a simple, practical setup that matched exactly what they needed at that stage of their business.
It's a good example of how 3MT approaches projects — practical solutions that match where a customer actually is, not where a equipment catalog assumes they should be.
Not all compost pellets easily. Materials with high concentrations of hard, abrasive, or dense particles can be significantly more demanding on both the feeding system and the pellet mill itself — accelerating wear and creating production challenges that affect the economics of the whole operation.
Before committing to a system design 3MT recommends material testing to confirm your specific compost material can produce a viable pellet at your target production rate. It's a straightforward step that protects your investment and gives both parties confidence before equipment is built or purchased.
One of the most common situations 3MT works with is operators who have capable mechanical people already on the floor but need someone to design the system correctly from the start and make sure startup goes smoothly.
If that sounds like your operation 3MT offers consulting and system design services that give your team exactly what they need — a properly engineered layout, equipment specifications, and a clear plan to build from. You bring the labor and mechanical capability, 3MT brings the system design expertise and the feeding equipment.
Once the system is built 3MT's startup and commissioning services make sure everything runs the way it was designed to. Having the right person on site during first production runs catches problems early, gets your team up to speed faster, and protects the investment you've made in the system.
It's a practical and cost effective way for operations with strong internal teams to get a professionally designed system without paying for full turnkey installation.

The PSM feeder handles compost well in most applications. Its surge hopper design absorbs the natural variation in how compost material flows and delivers a consistent controlled feed rate to the pellet mill — keeping production stable without unnecessary complexity.

Material handling and conveying systems are designed around your plant layout and material flow to keep compost moving cleanly through every stage of production.
Source material, moisture range, particle characteristics, and production rate targets all shape how a compost pelleting system needs to be built. 3MT designs around your specific material and operation — starting with confirmation that your material will pellet the way you need it to.
