Sound politics and a robust economy are essential ingredients for peace in human society. Most of the advanced countries in the world have both, and they could have sustained a peaceful atmosphere even after the 2nd World War. With the first and second Industrial Revolution, advances in science and technology development have brought economic fruitfulness and social wealth. The underdeveloped countries also need all of these things, which the advanced nations have already enjoyed over the last 200 years. For a peaceful society, these countries need at minimumto achieve food security, as well asa dependable energy sourcein order to sustain day-to-day life. The stable supply of agricultural products should be accomplished first, and a recycling system between production and regeneration of all the bio-waste would be necessary and worthy for achieving agricultural independence. All the bio-waste can be converted to the biogas by way of the fermentation process. In many developing countries, small farming is conventional,so an effective recycling and environmental protection infrastructure is perceived as very demanding. Biogas, however, can be used as a fuel; and its residues, following fermentation process, can be produced as an organic fertilizer for optimum agricultural development. Biogas in rural areas can also be used for heating, cooking or light. This organic fertilizer can significantly reduce the production cost of vegetables and crop harvesting. For agricultural purposes, it is crucial that organic fertilizer be suitable to increase the fertility of soil. To establish social equalities, microeconomic businesses have been suggested and implemented so far. Herewith we can support further development of ideas, which comprise seven benefits: local energy (i.e. biogas from swine manure) fertilizer ready to use (residues from the biogas process), local reduction of pollution (conversion of animal manure into energy in the confinement of a small plant),reduction of health risks (safer handling of manure) and the micro business option to sell biogas in a backpack, as well asthe reduced need to collect firewood, and the possibility to increase the number of cattle and pigs by dealing with the problem of manure waste. Micro biogas plants made from scrap building materials can make this enterprise possible.
