times the biogas compared to sewage sludge, and the biogas produced from AD systems exceeds the cost of processing the food waste and disposing of the residual bio solids. New York City alone operates 14 water treatment facilities, each of which features an anaerobic digester. Still, reports show that New Yorkers continue to seem reluctant to install disposers in the past 20 years since the ban was lifted, partially due to cost, but also because many might not realize they're actually legal. Pulper Alternatives Some foodservice professionals consider pulpers a more eco- friendly alternative to garbage disposers. These units grind up waste and remove water to reduce a foodservice opera- tion's waste stream. Pulpers can link to on-site dehydrators, which remove more water to create a lightweight, powdery substance that reduces hauling fees, but that can also be sent to a composter for further treatment to become a soil amendment. That ex- tra step is key if an operator wants to take the most environ- mentally friendly route. Large commercial pulpers utilize big cutting disks, a water press, a recirculating trough system and a 7 to 10 horsepower motor to consolidate and remove wet waste from disposables. There are two pulper categories. Close coupled, or standalone systems, are less expensive and don't require a custom build. The pulping and water extraction are facili- tated at the same place. This results in a less complicated installation and less cleaning overall because there are no remote lines that have to be maintained. Remote systems make up the other pulper category. They utilize a macerating chamber that grinds food waste, then pumps it to a water press in a remote location, such as a back dock, pulp collection room or somewhere away from the input area. Operators can fit this type of system with several macerators hooking into one water press. The discharge unit can be placed by the dumpster to save labor and additional grinding tanks can be added if there is more than one dish room. Operators also can have several grinding stations go to one discharge station when using a remote pulper. It's important not to place plastics in the machine — only organ- ics — to ensure the pulped material can be used as a soil amendment if that is the desired output. Use of commercial garbage disposers remains a thorny issue among some environmental and municipal camps, but when used in conjunction with more AD systems at wastewa- ter treatment plants, they can actually create more resources in the form of natural energy and soil amendments. Regard- less, disposers alone are just one of the growing number of tools out there to divert food waste from landfills, which is the overarching goal of getting as close to "zero waste" as possible.
