High moisture, high volume, and low bulk density make compost a tough customer when it comes to screening. The daily variability of moisture content can make the selection of screening media and opening size a real challenge, especially when using trommels or other conventional vibrating screen shakers. But there’s no problem if you have BIVITEC® on your side!
The BIVITEC® screen is used to screen compost across the country, making separations ranging from 1/2″ down to less than 1/8”. Composted yard trimmings, food scraps, bio-sludge, nothing is too difficult for the BIVITEC® to handle! The wetter and stickier the material, the brighter this screen shines.
In 2006, Ned Foley at Two Particular Acres in Royersford, PA began using a portable BIVITEC® screening plant in his composting operation. Ned was starting a compost facility at which he was collecting food scraps from various outlets for disposal at his site, and he needed a screen that could make the fine separations that were going to be necessary to make a high-quality, saleable product. With the BIVITEC® he was able to screen at a 5mm (3/16”) opening and produce a top-tier compost product. Two Particular Acres was later able to team with Haines & Kibblehouse (another owner of several BIVITEC® screens) to use their empty quarry pits for compost staging and processing.
A&M Composting in Manheim, PA is a subsidiary of JP Mascaro & Sons. This site operates two BIVITEC® screens in the process of composting sewage sludge. Even after composting, this material has very high moisture contents that can reach >60%. The BIVITEC® is relied on to make efficient separations at 3/8” no matter what the conditions or moisture levels, and it always produces a reliable, clean product.
Many municipalities rely on the BIVITEC® as a compost screening machine. From Palm Beach, Florida to southern California, the BIVITEC® is there to help you keep waste out of the landfill by recycling it into an environmentally friendly soil amendment.
