Sistema Biobolsa BB40
Sistema Biobolsa BB40 is a pre-fabricated biodigester that converts daily farm waste waste into renewable energy and organic fertilizer. This technology generates a sustainable source of energy in the form of biogas, for household or farm use, reduces the need for fuels and chemical fertilizers, and creates an opportunity for the farmers to improve their agricultural production. The system also generated a potent, natural fertilizer, Biol.
It is a continuous flow, tubular, prefabricated, modular, flexible biodigester. The system is composed of pre-fabricated components in order to optimize packaging, transportation and easy installation. It is easy to operate and maintain, and has a long durability.
Biogas displaces LP gas, gasoline and electricity; chemical fertilizers are replaced by biol.
The main market is Mexico. Sistema Biobolsa is developing in Central America, with a main office in Nicaragua.
Pilot projects and expansion include projects in Honduras, Haiti, Cuba, Peru, as well as in India and East Africa.
The product is distributed by Sistema Biobolsa itself and a network of distributors in all the targeted regions in Mexico and Nicaragua.
The market price for the BB40 is in the range USD 2,300 to 2,700.
Sistema Biobolsa offers with Kiva a 0% interest loan on up to 12 months to pay for the product. The payback time is estimated between 2-3 years.
The BB40 is targeting farmers that professionally produce and sell milk, cheese or animal fattening, with access to local and national markets. Average annual income of the target users is USD 7,000. The BB40 enables farmers to use the gas to run engines for electricity generation.
The farmers should have more than 100 animals and over 7 hectares of farmland to use BB40.

The manual of biol explains how the farmers can prepare and use the biol as a crop fertilizer.
The technology is patented.
160 BB40 have been distributed so far. interview with manufacturer
The BB40 model is part of a larger program, with a range of biogas plant sizes from BB4 to BB200: total of +3000 units installed.

– – Wrapped in its own packaging, therefore zero waste.
– – Easily shippable
The biodigester receives the daily farm waste and the manure is mixed with water (1 part manure to 3 parts water).
Sistema Biobolsa systems perform anaerobic digestions. Anaerobic digestion is the breakdown of organic material by micro-organisms in the absence of oxygen. It produces biogas, a methane-rich gas that also contains carbon dioxide with trace amounts of other gases; and digestate, a source of nutrients that can be used as a fertilizer. The digestion process begins with bacterial hydrolysis of the input material in order to break organic polymers into smaller molecules that finally become methane and carbon dioxide after acidogenesis and methanogenesis.
There is a free technical support provided by Sistema Biobolsa’s technicians:
– – An initial diagnostics is made by the technicians.
– – On the day of installation, there is a first training on how to use the system and how to use biogas.
– – After installation, there are three compulsory visits that include training
– -1 After 30 days, technical visit with a training on biogas.
– -2 After 90 days, technical visit with a training on biol.
– -3 After 180 days, technical visit with an evaluation of adoption and impact.
Sistema Biobolsa provides a replacement service.
The BB40 lasts over 15 years. The geo-membrane, tested in lab under UV radiations, has an estimated lifetime of 50 years.interview with manufacturer
There is 1 year warranty on any manufacturing defect. They also provide 20 year warranty on the geo-membrane.
Performance targets are established depending on the climate and the type of animal manure used.
The BB40 produces 14.6 m3, 9.7 m3, 5.8 m3 for hot climate (>23°C), temperate climate (15°C to 22°C) cold climate (<15°C) respectively.
Under temperate climate, the BB40 requires 242L and 161L of waste input for cow manure and other animals manure (pigs, goats, sheep, horses) respectively.

Since [extreme caution is necessary when working with biogas,] farmers are strongly encouraged to put a wiring around the system to restrict access. They also have to follow a formation taught by Sistema Biobolsa. Adequate ventilation, appropriate precautions, good work practices, and adequate personal protective equipment will minimize the dangers associated with biogas.
Stove and Boiler adaptation are included in the package.
The BB40 can be used to generate electric and mechanic electricity through the adaptation of small motors to pump water, create void before milking, chop food, refrigerate. The electricity generated can also potentially be sent back to the grid.

Sistema Biobolsa is certified B-Corporations. It also has the IS0 9001 certification.interview with manufacturer
Sistema Biobolsa developed their own criteria. They rely on traceability of each component from the manufacturing plant to field installation.interview with manufacturer
The design allows the interconnection of Biobolsa, aiming at increasing the system’s treatment capacity volume from 50m3 to 240 m3 in liquid phase.
Variety of sizes, with larger systems that go up to a digester capacity of 200m3: BB50, BB60, BB80, BB120, BB160, BB200. Watch large-size biodigestors in use.
Sistema Biobolsa has won many awards and recognitions: Social Business of the year, 2010 Businesses in Development (BiD Network); Ashden Award Finalists 2010; Green Tech Challenge Finalists; 2nd place Iniciativa México 2011; International Development Exchange Grant; Switzer Environmental Leadership Fellow; Echoing Green Finalists 2012; Fellow Ashoka, New Ventures México Negocio; Top 10 Entrepreneur of Latin America in 2012 by Univision; Buckminster Fuller Challenge 2014 Finalists.
Expert advisors have indicated that polyethylene, the main material, is cheap but has a shorter lifetime than other quality materials such as PVC (only the fittings are of PVC).
