Industrial grinders: raising the bar for zero waste

Our grinders are revolutionizing waste industries. We recognize that industrial waste and waste disposal is a significant environmental challenge, with waste steams arising from agriculture, construction, demolition, manufacturing, and forestry operations.

For a long time, landfill and incineration were default methods of disposal, but environmental pollution, greenhouse gas emissions, and the depletion of valuable natural resources are driving the need for more sustainable approaches. This is where heavy-duty industrial milling and grinding machinery can literally transform waste into valuable fiber.

From our stand-alone low revs per minute (rpm) grinders to mid-speed shredders, super shredders and extremely powerful WSM Titan horizontal grinding systems, our grinders, including all-electric models, can convert even the most challenging urban and waste wood residues to a consistent quality fiber that can be used across the processed wood industries.

Zero wood waste is an ambitious, but achievable goal. Through innovative solutions, cross-industry collaborations, and the right wood processing technology, we can ensure that zero wood waste is not just an ambition, but a reality.
