The food waste at Rutgers New Brunswick can be converted to bio-fuel through the means of anaerobic digestion
Abstract (type = summary)
Rutgers currently spends more than $100,000 per year to get rid of leftover food at its four dining halls. A local pig farmer, Steve Pinter of Pinter farms is paid to haul away about 10 tons of food waste per day from the four dining halls, which he reportedly feeds to his pigs. Although it is a good thing that the food waste does not end up in a landfill contributing to the greenhouse gas emissions, we believe that we are paying to throw away a useful commodity. By implementing an anaerobic digestion chamber on campus this food disposal fee will no longer be required. The philosophy behind the anaerobic digester is that the leftover will be converted to natural gas that can be utilized by Rutgers. This is achieved by specifying conditions within the chamber that are optimal for specific microorganisms that breakdown the leftover foods and convert them to gas. The process is akin to composting. The starting cost to implement the chamber will be outweighed over the span of a few years by the amount the University saves by not paying the pig farmer. This does not include the savings from the utilization of the fuels generated by this process or the environmental benefit of the chamber.
