While energy production is the most obvious output of a bioenergy system, it is not the only significant component. Economic success depends on efficient management and marketing of the nonenergy products. There is a symbiotic role for nonenergy technologies to be nested within the bioenergy conversion technologies. Anaerobic digesters are a great example of the complementary, multiple markets that must be occurring at the same time for a digester to operate in the black. The energy revenue alone does not cover the costs. Digesters can cost more per kWh than the energy value of the electricity as long as the sum of all the products sold for nonenergy products create a total revenue per kWh that is greater than the cost per kWh.
