Short description of the project:
Modified Anaerobic Digestion (ModAD) technology, developed at San Diego State University with a grant from the Grand Challenge Explorations Program of the Bill and Melinda Gate Foundation, has the potential to address the sanitation challenges in developing countries. Laboratory results showed that the technology can be developed into a reliable, affordable, and sustainable waste treatment system (Garoma and Williams, 2012). ModAD technology has produced residual biosolids that meet US Environmental Protection Agency (USEPA) requirements for pathogen and volatile solids reductions, thus these biosolids can be applied to soil as fertilizer (USEPA, 1999). In addition, the technology recovers biogas as a fuel for energy. The recovery of these resources, biosolids and biogas, provide additional incentives for a community to adopt and sustain this technology.

The ModAD technology is versatile and the design can be modified to fit for communities of all income levels. Furthermore, it can be scaled to treat waste at any size facility, from a group of households at rural communities to a high rise building in big cities.

The goal of this project is to modify and adapt an anaerobic digestion system that will treat waste and generate a reliable supply of biogas from the co-digestion of algal biomass and waste.

Start and end date: 31 Oct 2011, final report due 30 October 2013
Grant type: GCE R7
