Codigestion In Central Florida
The codigestion facility includes a mixing tank, two complete mix anaerobic digesters operated in parallel, and a post digestion tank with a biogas holder mounted to the top (seen at right).

New digester in the Orlando region processes 130,000 tons/year of biosolids, fats, oils, grease and food waste,

producing power, a Class AA granular fertilizer and phosphorous-rich struvite.

Agricultural Anaerobic Digestion In The U.S.
Figure 2. Technologies at farm AD facilities

The number of digesters at agricultural operations increased in 2012 — although less than 2 percent of dairy and swine operations in the U.S. have AD systems.

Improving Economics Of Codigestion
Figure 1. Organic waste tipping fee required based on electricity cost

The economics of an organic “waste to energy” facility are strongly dependent on the waste characteristics,
and costs of digestion and solids processing after digestion. Part I
