Agri-energy Crops for Biogas Production Regimes 2021 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/8743 https://ijiaar.penpublishing.net/ G. Dražić N. Rakašćan N. Dražić The most significant challenges posed to agriculture are connecting multiple segments in a sustainable way that includes resource and energy efficiency as well as environmental protection through the rational use of limited resources. One way is to use field crop biomass as a feedstock for biogas production in the process of anaerobic digestion. Codigestion of manure and energy crops biomass reduces the impact on the environment primarily through reducing greenhouse gas emissions during the entire life cycle of the plant. Energy crops should meet the basic conditions: efficient conversion of solar energy in the process of photosynthesis that allows high yields, low requirements for nutrients and water due to a well-developed root system, low requirements for agronomic measures, low cost of establishing and maintaining plantations. The main factors that determine the biogas yields are the type and variety of crops, harvest time, method of storage and pretreatment before AD conversion and nutrient content. The most used field crops are maize (silage, grain), sorghum (fodder and sveet) due to their high potential for methane production and mature technologies. Lignocellulosic biomass of field residues of field crops or originating from purpose-grown perennial crops such as switchgrass, miscanthus, reed canary grass, Napier grass has significant environmental advantages but also technological limitations (pre-treatment is necessary). The success and future potential for the role of biogas technologies in integrated infrastructures providing bioenergy, biomethane for static and mobile applications, bio-CO2, and even play a key role in the circular economy by recycling nutrients back into the land through the use of digestate which is by-product as soil amendment in energy crops production chan article 10.29329/ijiaar.2021.358.8 5 2 230 240 2602-4772 International Journal of Innovative Approaches in Agricultural Research
