Abstract: Some of the main envi­ron­men­tal prob­lems of today’s soci­ety are the con­tin­u­ous increase of the amount of organ­ic residues and the con­sump­tion of con­ven­tion­al (non-renew­able) ener­gy. One way to address these issues is through the pro­cess­ing of this residues and the pro­duc­tion of bio­gas. Anaer­o­bic diges­tion is con­sid­ered to be the opti­mal treat­ment for var­i­ous types of agri­cul­tur­al and wood bio­mass and for a wide vari­ety of organ­ic residues suit­able for this pur­pose, these sub­strates being thus trans­formed into recov­er­able ener­gy and organ­ic fer­til­iz­er for agri­cul­ture. Anaer­o­bic diges­tion is a micro­bi­o­log­i­cal process of decom­po­si­tion of organ­ic mat­ter, in the absence of oxy­gen, applied on a large scale for the pro­duc­tion of renew­able ener­gy. The paper presents a series of con­sid­er­a­tions on obtain­ing bio­gas through anaer­o­bic diges­tion from agri­cul­tur­al bio­mass, wood, ener­gy crops and food waste.
Key­words: bio­mass, bio­gas, anaer­o­bic diges­tion, methano­gen­e­sis.
