When your business model is built on turning waste into value, every load matters - and at Rockwood Sustainable Solutions in Tennessee, USA, every load is processed with precision.<\/p>\n

Rockwood specializes in handling construction and demolition (C&D) materials - the tough, tricky stuff like drywall, metal, concrete, wood, cardboard, and tires.<\/p>\n

They go beyond collecting and sorting waste; they take the stress out of the process for their customers by handling everything from Tommy carts in high-rises to LEED-certified reporting.<\/p>\n

In everything they do, Rockwood\u2019s focus is on diverting as much waste as possible from landfills by extracting valuable commodities. In 2023, the team\u2019s high ambitions for reclamation, however, went beyond what they could deliver:<\/p>\n

\u201cWe found ourselves falling short of our expectations,\u201d says Charles Hartsell, Chief Operating Officer.<\/p>\n

So, Rockwood decided to invest in an industrial waste shredder, which could improve the amount of value extracted as well as boost their output:<\/p>\n

\u201cThe M&J shredder enables us to process more tonnage, meaning more business every day. We used to do 250-300 tons a day. Today, that\u2019s up by 100 tons. That's significant in the C&D world, \u201d Charles adds.<\/p>\n

It ate challenging waste like it was a cookie<\/h4><\/div><\/div><\/div><\/div>

As part of their research to find their new shredder, Rockwood demoed and rented an M&J M4000 (previously known as M&J 4000M) mobile pre-shredder and quickly saw its capability to handle even oversized and challenging bulky waste:<\/p>\n

\u201cIt literally ate it like a cookie. It was very, very impressive.\u201d<\/p>\n

Charles and his team tested other shredders, but nothing came close to the M&J M4000:<\/p>\n

\u201cWe researched a lot of different shredders that were on the market but none of them compared to the M&J, so the choice was clear and that's why we own a M&J 4000. It simply outperformed the competition\u201d, Charles says and continues:<\/p>\n

\u201cThe M&J just seemed to do everything I needed it to. If I needed it to climb a pile, it could climb it. The speed was second to none. With others, you had to pre-sort. Not with this. If it's in the pile, the M&J can shred it.\"<\/p>\n<\/div><\/div><\/div>
