THE BENEFIT OF BIOGAS IN AGRICULTURE

VANGELICA JOVANOVSKA, MILA ARAPCEVSKA, KATERINA BOJKOVSKA

Abstract: Becouse of pollution problems, specialy associated with inadequate management of animal manure and organic waste, emphasises the need for appropriate solution to deal with the problem. A streghtening of the overall policy on enviromental protection, as regards waste as well asmanure handling, with well defined enforcement measures, will stimulate the dissemination of the appropriate of the biogas tehnologies. The application of animal manure, organic waste and other types of biomass as energy sources will depend to a large extend on availability. Availability and implementation is strictly dependent on governments and EU agricultural, environmental and energy policies. Co-digestion of animal manure and other types of suitable organic waste in biogas plants is an integrated process. On the background of renewable energy production, the process includes interwined environmental and agricultural benefits, such as:
- saving for the farmers-improved fertilisation efficiency,
- less greenhouse gas emission,
- cheaper and environmentally sound waste recycling,
- reduced nuisance from odours and flies,
- possibilities of pathogen reduction through sanitation, all this connected to renewable energy production,
The attached flow diagram shows the main stream of integrated process.
