Biogas Digest Volume I: Biogas Basics
Biogas digest Volume II, Biogas - Application and product development
Abstract:Before a biogas plant is built or a biogas program is implemented, a techno-economic assessment should be made. For this, two sets of cost-benefit analyses have to be carried out:
· The macro-economic analysis (economic analysis) which compares the costs of a biogas program and the benefits for the country or the society.
· The micro-economic analysis (financial analysis) which judges the profitability of a biogas unit from the point of view of the user.
In judging the economic viability of biogas programs and -units the objectives of each decision-maker are of importance. Biogas programs (macro-level) and biogas units (microlevel) can serve the following purposes:
· the production of energy at low cost (mainly micro-level);
· a crop increase in agriculture by the production of bio-fertilizer (micro-level);
· the improvement of sanitation and hygiene (micro and macro level);
· the conservation of tree and forest reserves and a reduction in soil erosion (mainly macro-level);
· an improvement in the conditions of members of poorer levels of the population (mainly macro-level);
· a saving in foreign exchange (macro-level);
· provision of skills enhancement and employment for rural areas (macro-level).
