چکیده انگلیسی
The full-scale digester consisted of five 786Â m3 reactors (one biogasification reactor and four hydrolysis reactors) treating a 50:50 mix (volatile solids basis) of food and green waste, of which 17% became biogas, 32% residual solids, and 51% wastewater. The NPW of the projects were similar whether producing electricity or CNG, as long as the parasitic energy demand was satisfied with the biogas produced. When producing electricity only, the power output was 1.2Â MW, 7% of which was consumed parasitically. When producing CNG, the system produced 2Â hm3Â yâ1 natural gas after converting 22% of the biogas to heat and electricity which supplied the parasitic energy demand. The digester system was financially viable whether producing electricity or CNG for discount rates of up to 13%Â yâ1 without considering debt (all capital was considered equity), heat sales, feed-in tariffs or tax credits.
