The study looked at how the time spent processing dairy manure affects bioenergy production in Ohio and Hawaii. They found that longer processing time reduces bioenergy production in both states. In Hawaii, the best results were seen with a 30-day processing time, producing 11.2 × 104 GJ of energy. The study also showed that producing bioenergy year-round is better for both energy production and reducing greenhouse gas emissions. Lowering the nitrogen levels in the process can increase bioenergy production while also reducing energy needs and slightly increasing greenhouse gas emissions. Overall, running a biorefinery for a short time and using diluted waste can provide bioenergy with lower energy requirements and greenhouse gas emissions.
