This is a project about cardboard pellet makers in Germany. A medium-sized waste management and recycling company based in Hamburg decided to invest in two single-unit cardboard pellet makers to convert recovered cardboard and paper residues into high-density fuel pellets for industrial boilers and small-scale biomass heating systems.
This is a project about cardboard pellet makers in Germany. Germany has long been a global leader in recycling and sustainable energy practices. With strict regulations on waste management and a strong push for renewable energy sources, many companies are exploring innovative ways to utilize cardboard and paper waste. A medium-sized waste management and recycling company based in Hamburg decided to invest in two single-unit cardboard pellet makers to convert recovered cardboard and paper residues into high-density fuel pellets for industrial boilers and small-scale biomass heating systems.
The client’s primary objective was to reduce landfill waste while creating a profitable energy product. They had previously relied on outsourcing cardboard shredding and pellet production, but rising costs and inconsistent quality prompted them to purchase single units for in-house processing. This also allowed them to integrate the machines into their existing workflow alongside other recycling equipment without committing to a full-scale pellet production line immediately.

1.0–1.2 T/H
Model:
MZLH420
The install period:
1 Day
Total Power:
90 kW
Pellet Diameter:
6–8 mm
The client operates within the waste-to-energy and recycling sector, focusing on recovered paper, cardboard, and packaging materials. Their products are primarily:
Given the high fibrous content of cardboard and the variable moisture in recycled paper, the client required a robust pelleting machine capable of handling heterogeneous material. After detailed consultations with RICHI Machinery, they chose the MZLH420 cardboard pellet maker, suitable for medium-scale production.
Key specifications:
This cardboard pellet maker in Germany ensures consistent pellet density and size, which is crucial for maintaining high calorific value and stable combustion in German industrial boilers.
The client’s raw materials consist of:
Before pelleting, the materials undergo shredding and drying to 10–12% moisture content, ensuring smooth pellet formation and preventing clogging of the ring die. The MZLH420 cardboard pellet maker in Germany can process cardboard strips, shredded boxes, and pulp-like recycled paper efficiently, producing pellets with a diameter of 6–8 mm, which are ideal for:
The client also experiments with mixing shredded cardboard with sawdust or wood chips to enhance pellet density and improve burn efficiency during winter months.
The cardboard pellet maker in Germany offers several advantages:
Even as single-unit machines, they integrate seamlessly into the existing sorting, shredding, and drying workflow, enabling immediate pellet production without extensive modifications to their facility.
RICHI Machinery shipped the machines via ocean freight to the Port of Hamburg, Germany. The services included:
This approach allowed the client to start production quickly, reduce operational costs, and immediately generate revenue from previously discarded cardboard waste.
The MZLH420 cardboard pellet maker is a versatile biomass pelletizer, capable of handling:
Technical highlights include:
These features make it suitable for continuous production and varying raw material composition, ensuring reliable pellet quality year-round.
The client provided positive feedback:
"The MZLH420 cardboard pellet makers have transformed our waste management operations. They produce dense, uniform pellets that burn consistently. RICHI Machinery’s installation and training support was exceptional, and we now save on outsourcing costs while generating additional revenue."
They emphasized that the machines’ reliability, durability, and pellet quality were decisive in choosing RICHI over other manufacturers. Plans are underway to expand the operation by adding more units as demand for biomass pellets in Germany continues to grow.
