Size Reduction for the Packaging Industry

Packaging materials come in many forms—and WEIMA equipment is built to match. From single-shaft to four-shaft shredders and a range of drainage press sizes, our equipment portfolio demonstrates a strong commitment to sustainable processing. Each machine is engineered to deliver reliable performance and efficient handling of packaging materials, both now and in the future.

Custom solutions for every application

Every application is different, which is why WEIMA shredders are designed to be tailored to specific needs. Our goal is simple: deliver the ideal solution for each job. Machines can be outfitted with a variety of rotor and knife configurations to maximize shredding performance.

WEIMA rotors features replaceable knives and an adjustable cutting gap—referred to as “overstand”—for precise material processing. The result is consistent particle sizing, increased throughput, reduced energy usage, flexible application options, and minimized wear over time.

Optimize Recycling with Industrial Shredding Technology

WEIMA is globally recognized for high-performance industrial shredders known for their precision, power, and efficiency. For over four decades, we have shown manufacturers how beneficial it is to shred production waste where it’s created, maximizing labor costs, reducing handling, and increasing sustainability.

WEIMA shredders are designed to process a wide range of packaging materials, including plastics, cardboard, certain metals, and composite materials, ensuring efficient and reliable recycling across industries.

High-Performance Drainage Presses for Packaging Recycling

In addition to shredding technology, we manufacture advanced drainage presses and compression equipment designed to handle both empty and filled packaging. These systems compact bottles, cans, and flexible packaging into dense discs (200 mm and 300 mm diameters). This process supports faster material recovery, waste volume reduction, and recycling preparation. Extracted liquids can be reused or disposed of properly, while the compressed materials are easier to store, transport, and recycle—improving overall waste handling efficiency.

Customer spotlight: New Belgium Brewing

New Belgium Brewing, a pioneer in sustainable craft beer production, partnered with WEIMA to improve efficiency and manage increasing packaging and production waste. By implementing the WEIMA G.200 drainage press, the brewery gained a more effective way to process filled and empty cans, compressing them into compact discs while extracting residual liquids. This solution streamlined waste handling, reduced volume for transportation, and made recycling easier and more cost-effective. The stainless-steel system also improved cleanliness and maintenance, supporting New Belgium’s commitment to environmental responsibility and operational efficiency as the company continues to grow.
