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.

Codigestion Potential At Large-Scale Wastewater Treatment Facility
The Deer Island facility has twelve 3-million gallon mesophilic digesters

A study for the Deer Island treatment plant in Boston Harbor evaluated the feasibility of codigestion, and whether the economic benefits outweigh the costs.

Codigestion Research Builds Facility Operator Confidence
Figure 2. Nutrient limits in food waste digestion

Research can improve the economic viability of codigestion facilities and ease concerns of managers of water reclamation facilities about receiving additional organic waste and the potential for digester upsets. Part II

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
