5T/H Cardboard Pellet Mill in the United States

Choosing the Right Cardboard Pellet Mill for American Conditions

After evaluating several pellet press suppliers, the company selected MZLH678 cardboard pellet mill in the United States— and they ordered two units. Here's a snapshot of the machine specs:

Combined, these two cardboard paper pellet making machines can handle up to 5 tons of finished pellets per hour — a perfect match for the volume of clean cardboard waste the company already collects from local warehouses, retail stores, and packaging plants.

What's Going Into These Cardboard Pellets?

Unlike agricultural biomass or wood waste, waste cardboard has its own unique properties. It's already low in moisture and has decent energy content but can be tricky to densify if not processed correctly.

The recycling company runs the cardboard through industrial shredders and hammer mills to get a consistent flake size. A light drying step ensures moisture stays under 12% — optimal for the cardboard pellet press to compress the fibers into uniform fuel pellets.

Occasionally, they blend in a small percentage (5–10%) of clean, non-laminated paper scrap to improve binding and burn quality. But the majority of the input is purely cardboard, carefully sorted to keep out plastics and adhesives that could ruin pellet quality.

How This cardboard pellet mill in the United States Helps the Business Compete

Before adding the cardboard pellet mill in the United States, the company was fully dependent on selling bales of OCC (Old Corrugated Containers). Now, with these pellet presses, they control more of the value chain.

Pelletized cardboard burns more efficiently than loose waste, stores easily, and moves at lower cost per BTU. Local district heating plants and industrial greenhouses have shown strong interest in substituting cardboard pellets for traditional wood pellets or coal.

Besides selling to nearby biomass plants, the company is exploring partnerships with municipal utilities that want to boost their renewable energy mix with locally produced solid fuels.

What Else Can a cardboard pellet mill in the United States Produce?

A big advantage of choosing RICHI's heavy-duty cardboard pelletizer is its flexibility. While the main focus is cardboard, the same machine can easily process:

• Agricultural residues like corn stalks or straw.
• Waste paper pulp left over from shredding operations.
• Light wood shavings from local cabinet makers.
• Clean sawdust blends.

With a quick change of the ring die, the customer can adjust pellet size and compression to match different feedstocks. This gives the recycling firm a powerful hedge against market swings: when cardboard supply dips, they can switch to other local residues without needing new equipment.

Real Impact on Local Communities and the Environment

In the USA, sustainability standards are tightening across industries. Many manufacturers, schools, and municipal heating plants want reliable alternatives to fossil fuels — but they also want fuel that's truly renewable and locally sourced.

By converting clean cardboard into fuel pellets on-site, this recycler reduces waste hauling costs, shrinks landfill volume, and cuts carbon emissions from long-haul transport to distant paper mills.

At the same time, they create a consistent, high-energy biofuel that fits right into modern biomass boilers. This helps their region move closer to carbon-neutral heating goals — and keeps valuable dollars circulating in the local economy.

How RICHI Supported This Project from Start to Finish

When the client first reached out, they had never run a ring die pellet mill before. RICHI's team helped them choose the right cardboard pellet press, adjust the die compression ratio for recycled fiber, and design a simple yet robust feeding system that avoids blockages.

RICHI engineers also provided on-site commissioning support and training for operators — ensuring the customer knew exactly how to run, maintain, and adjust the machines for maximum uptime.

No-Nonsense American-Style Return on Investment

One thing that made this cardboard pellet mill in the United States project possible was the clear ROI. With a stable local source of waste cardboard, the client expects each cardboard pellet mill to pay for itself within 18 months.

By adding value to what was once sold as a low-margin bale, they now command higher per-ton prices for clean, easy-to-burn biofuel pellets. And because they already own the shredding and sorting lines, the investment risk stays low.

Why Other US Operators Are Looking at Cardboard Pellet Mills

As more states roll out landfill diversion targets and clean energy incentives, cardboard pelletizing will only get more attractive. Whether you're a recycling yard, a packaging waste processor, or a logistics hub with lots of boxes flowing through, a good cardboard pellet mill can be your ticket to transforming waste streams into steady, profitable biofuel production.

And with reliable machines like the RICHI cardboard pelletizer, you can scale at your own pace — start small with one unit or ramp up to multiple lines as demand grows.
