ARTI Biogas Plant

Distributors / Implementing Organizations

This product is implemented by ARTI.

Manufacturing/Building Method

ARTI manufactures 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 about 3-4 hours and can be done by one person.

Intellectural Property Type

Open Source

User Provision Model

Users can obtain a system from ARTI or build the system themselves from off-the-shelf parts.

Distributions to Date Status

ARTI has installed 1000 systems since 2003 and installs 30-50 per month. The organization approximates that 2000 more have been built from DIY instructions.

Design Specifications

ARTI is made from two high-density polyethylene (HDPE) water tanks that are cut-down and adapted using a heat gun and HDPE piping. The size of the system is 1.4 m x 1.4 m x 2.5 m. 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.

Manufacturer Specified Performance Parameters

Designer-specified performance targets include: compact, efficient, and fast.

Vetted Performance Status

Independent academic research performed in Tanzania found that 2 kg of kitchen produce is able to produce about 200 liters of biogas. It was also estimated that plants could be fed 5 kg/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 a lack of education and assistance. Performance details can be found at Build-a-Biogas-Plant and Howtopedia.

Safety

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.

Complementary Technical Systems

Complementary technical systems for biogas products include stoves, commercial burners, water heaters and gen-sets.
