Concho is the latest addition to the Guilford College Sustainability crew. You may have heard of chipper/ shredders, but Concho is very unique type of shredder/ grinder. More specifically, Concho is a Compost Shredder/ Grinder. Concho was built by Lindig Manufacturing Corp. in the 1970s. You can imagine our excitment when we stumbled across the craigslist add for the Concho Compost Shredder/Grinder as we’ve been looking for a way to further breakdown or sift our finished compost. We’ve also been on the hunt for a way to more finely shred some of the materials we put into our Eartub, particularly the corn based compostable cups, plates, and flatware that we use at our catered events. We think Concho can accomplish both of these objectives. We have found that the compostable disposables we use do break down in the Earthtub, but not very quickly. Also when a very large amount of these materials are put into the Earthtub, they tend to float on top, and the auger is not able to pull these materials into the active compost.
So after a bit of haggling with the craigslist seller over the phone, we drove out to Clemmons, NC to pick this thing up. We didn’t really know what to expect, as the seller didn’t really know much about it. He was in the construction business and they had found Concho abandoned on a job site. All he knew was the make and model and that it had a 7 HP Briggs and Statton motor. He had received one inquiry from Pennsylvania who was very interested, and told the seller that these pieces of machinery were pretty rare and that Lindig was not in business anymore. The interested buyer had decided that it was too far to drive though, and he hadn’t had another offer until we came along.
So we got concho back to campus we relative ease, but weren’t exactly sure how to use it. We knew we wanted to feed our compostable disposables through it, but didn’t know how to do it without making a huge mess, because as you can see the materials feed out of the very bottom of the unit, very low to the ground. But with a little ingenuity and our trusty forklift, we were able to raise Concho above the Earthub hatch, and feed materials directly into the Earthtub. We’re hoping this will add a more favorable element to our mix.
