ARTI Biogas Plant
Appropriate Rural Technology Institute (ARTI)
The ARTI is a domestic biodigester technology useful to generate gas primarly from cattle dung.
The ARTI biogas plant is a system developed by India’s Appropriate Rural Technologies (ARTI), it converts food waste into methane-rich gas. The system is compact for urban use, suitable for both cities and farms, and designed to handle high-calorie feedstock such as leftovers, spoiled food and other kitchen waste, green leaves and other starches and sugars rather than manure or human waste.
ARTI is the distributor of the system.
Approximately $156 USD (10,000 INR).
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all.
Households that have at least 6 to 8 heads of cattle.
ARTI builds the digesters from off-the-shelf plastic storage tanks and third-party plumbing kits and biogas stoves supplied by Samuchit Enviro-Tech (SET) Pvt. Ltd. The installation time is of about 3-4 hours and can be done by one person.
Users can obtain a system from ARTI or build the system themselves from off-the-shelf parts.
ARTI has installed 1000 systems since 2003 and installs 30-50 per month. The organization guesses that 1000 more have been built from DIY instructions.
ARTI is made from two high-density polythene (HDPE) water tanks that are cut-down and adapted using a heat gun an HDPE piping. One of the tanks is placed upside down in the upper part of the system to hold the gas, whilst the other one holds the slurry. The system also has an inlet and an overflow so that users can both add feedstock easily and remove digested residue. With the purpose of letting users employ the gas as a cooking fuel, a pipe is put in place to take the biogas to the kitchen.
Product Dimensions: 1.4 m x 1.4 m x 2.5 m
Technical support is provided by ARTI.
Replacement parts can be found off the shelf from third-party suppliers.
The system is designed to output 500g of methane for every 2 kg of feedstock.
Independent academic research performed in Tanzania found that 2kg of kitchen produces is able to produce about 200 liters of biogas. It was also estimated that plant could be fed 5kg/day producing 670 liters of biogas per day. The researchers recommended that additional customer service and training be available for the ARTI system due to frequent system failures resulting from lack of education and assistance. Performance details can be found at build-a-biogas-plant.com, and Howtopedia.

Extreme caution is necessary when working with biogas. Adequate ventilation, appropriate precautions, good work practices, and adequate personal protective equipment will minimize the dangers associated with biogas. Wherever possible, digester-associated tasks and maintenance should be performed without anyone having to enter confined spaces, including pits.
Biogas use products are available on the market including: stoves, commercial burners, water heaters and gen-sets.
