Spruce bark beetles as a biological waste that can be processed on a biogas plant

Original language description

Biogas plays an important role in reducing the amount of bio-waste that is converted to methane usable by multiple pathways in the energy sector. Bark beetles belong to the most important pests of spruce forests in Europe. Principal measures of managing bark beetle populations include their trapping by pheromone traps. Biomass of bark beetles collected by the traps constitutes a waste of forest that can be potentially processed in biogas plants. The aim of study was to provide information about trapping of bark beetles by pheromone traps in Tatra national park during a period of 2005-2018 and to verify the energy potential from a combination of liquid digestate and bark beetle biomass collected by pheromone traps. The bark beetle biomass is a seasonal small-volume nitrogen rich material which could be processed at agricultural biogas plants. The biochemical methane potential batch test performed at 40oC showed high degree of digestion of milled beetles within 40 days with the methane production of 0.242 mN3 per kilogram of total solids. The single-stage low-solids mesophilic fed-batch anaerobic digestion of untreated beetles was carried out in a lab-scale rotary drum reactor. Within 52 days the average organic loading rate was 1.019 kgVS m-3 d-1. The specific biogas and methane production reached 0.218 mN3 kgTS-1 and 0.140 mN3 kgTS-1 respectively. The cuticle of beetle bodies was not obviously disturbed by the fermentation process. The digestate was quite rich in nitrogen, but the other elements contents did not differ too much from fertilizer made from manure or phytomass.
