Crumbler® Rotary Shear
Save costs and improve feedstock quality
Size reduction is a key processing step for feedstocks. Traditional methods include hammermills, grinders, and chippers. However, these methods typically are either limited to producing ½” and larger particles or require pre-drying of biomass at a substantial energy cost. Additionally, these methods may produce large amounts of fines with wide particle distributions and poor flowability.
Forest Concepts developed the Crumbler® rotary shear to address these common problems and produce a superior result.
- Processes any moisture content – no pre-drying necessary
- Scalable for both small & industrial-scale operations
- Tested on many materials – wood, recyclables, corn stover, hemp & more
- Results in evenly shaped highly-flowable particles with less fines
- Efficiently produces particles as small as 1mm

Application of Crumbler® Technology to Recovered Plastics and MSW for Chemical Recycling and Waste to Energy
Abstract Crumbler® rotary-shear technology from Forest Concepts is the solution to produce high quality feedstocks. This short presentation explains some of our emerging work in applying this patent-protected technology to recovered plastics and MSW for chemical recycling and waste to
Abstract Roundwood logs from forests and energy plantations must be chipped, ground, or otherwise comminuted into small particles prior to conversion to solid or liquid biofuels. Results & discussion: Rotary veneer followed by cross-grain shearing is demonstrated to be a
Abstract Forest Concepts, with funding from USDA NIFA SBIR program, developed methods and equipment to reprocess low-value dirty forest chips, tree service chips, and hog fuel into high value clean wood fiber and other valuable fractions. Traditional clean sources of
Abstract We have an objective to convert cellulosic biomass raw materials into small particles that are optimized for biochemical and/or thermochemical conversion to liquid transportation fuels. As a side effort, we are interested in producing feedstocks for composite bioproducts, solid
