How to Build the ARTI Compact Biogas Digestor

Problem: Cooking fuel, waste disposal, inefficiency of traditional biogas cattle dung digesters

Idea: A very efficient process of biomethanisation thanks to high calorie content of the waste used for the bacteriological digestion. The system is usable by any household.

Difficulty:Construction: easy to medium, use: easy. The digester should be kept at temperatures between 32 & 37°C (89.6-98.6°F)

• Price Range: About 100$ with new material
• Material Needed: 2 plastic water tanks, one of 1cubic meter, the other of 0,75 cubic meter content, flexible pipe, stable
• horizontal base, frame to stop the gas tank rise, inlet and outlet fittings
• Geographic Area: Global, in temperate to cold climates, the plant has to be heated
• Competencies: Simple plumbing skills
• How Many people? 2
• How Long does it take? From three to max. ten hours construction time, two weeks to start the methan production
