Sažetak
Growing concerns about the current energy crisis and the impact of fossil energy on the environment has recently accelerated the development of sustainable and green energy on a global scale. Following the above, the EC has published the REPowerEU (COM (2022) 109) in May 2022 which encourages the increase of biogas production in the EU member states by 20 % by 2030. Sustainable energy production is mandatory from the entry into force of the EU regulative which defined the goals for reducing the GHG emissions. For the sustainable biogas production, a potential problem arises when using non-sustainable raw material ; namely, currently the most commonly used raw material in the biogas production is corn silage of the whole plant. It is well known that corn is used for food and feed, which means that the competition has been created between the production of energy and food/feed from the same crop. Therefore, the aim of this research was to analyse the possibility of using corn stalk by-products in the production of ensiled high- moisture corn cob for livestock feed. The research has shown that the biogas potential of corn silage without cobs (CSWC) was assessed. The interpretation of the data has shown the possibility of using CSWC (100-120 NL/g DM) as a co-substrate in the biogas production, which could lead to reducing the aforementioned competition between energy and food/ feed production while ensuring a sustainable biogas production.
