Abstract
The high percentage of fats, oils and grease (FOG) in wastewater discharges from kitchen waste streams is increasing rapidly due to the increasing demand for food and modern lifestyle. Direct discharge of FOG into sewer system results in many environmental and technical problems. It is energy-rich waste, while effective management is required to recover its energy. FOG collection from wastewater lines prior to discharge into the sewer networks is essential, and further conversion into biofuel could generate additional revenue. Therefore, recent research is focusing on different routes of FOG conversion into usable biofuel. Deep energetic and environmental analysis of FOG conversion into bioenergy concluded that FOG conversion is a very promising route for various biofuel production. This chapter presents an overview of engineered challenges related to various technologies used for energy recovery from FOG wastes and biofuel production. The different routes of biofuels production (e.g., biohydrogen, biomethane and biodiesel) through new integrated routes for sustainable biofuel industry are evaluated. Herein, this chapter provides a successive high throughput of the full conversion of FOG wastes into biofuel toward a zero-waste system.
