“Dry fermentation“ technology may be used for energy recovery of phytomass substrate which has dry matter content from 20 to 60%. In agriculture sector, while only rarely used, it is a very perspective technology at such types of biomass – phytomass which is not recommended to be processed within “wet fermentation” (process is energetically and operationally very costly). For detecting the suitability of Miscanthus × giganteus phytomass to biogas for production through dry fermentation process, as well as determining the biogas yield, at the Slovak university of Agriculture (SUA) there has been developed an experimental device enabling the pilot plant trials, which is installed at the biogas station within the area of the VPP SPU Ltd. in Kolíňany. A pilot plant experiment of biogas production based on Miscanthus × giganteus (Miscanthus sinensis Anderss.) phytomass within dry fermentation process was carried out at the period from 25 February to 25 March 2013. The monitored production of biogas was based on the substrate mixture of components formed as follows: the biomass from preceding cycle (farmyard manure) and ensilage from Miscanthus phytomass. In these experiments the amount of produced biogas, analysis of biogas and the input substrate were materialized by standard methodology. On base of the obtained results, we can formulate the conclusion: the tested substrate mainly consists of Miscanthus phytomass and manure was suitable for biogas production technology and anaerobic dry fermentation process. The yield of Miscanthus substrate in our experiments was around 117 litres of biogas per 1 kg of dry matter silage. For assurance of the continuity and uniformity in the production of biogas by dry fermentation process, the multiple-fermentation chamber is needed, which must be saturated gradually with dosing interval.
