The use of cereals for biogas production
 FENCL, Lukáš
In these days, renewable resources is a very current topic which also includes biogas production in agricultural biogas stations. Some of the main raw materials used to produce biogas are cereals, which we will be focusing on in this thesis. The use of cereals for energetic purposes results in decreasing the state of non-renewable resources in nature. The aim of this bachelor thesis is to summarise findings of various possibilities for utilisation of cereals to produce biogas and compare cereals of the 1st and 2nd group. Describe biogas and biogas station linked with it as such, we used biogas station in company ZS Kozojedy, a.s. Cereals are split into two groups and in order to produce biogas you may use both of these groups. Bachelor thesis is mainly focused on two main crops which are now a days very important for production of biogas. Included between these two crops also are: firstly maize, which has worldwide representation in crops grown mainly to make silage; and secondly rye which is more part of new crops from which silage is already being made.
