System dimensions (m)
The Biobolsa has two main components, a reactor and the tubes and assemblies, The reactor is made with linear low density polyethylene (LLDPE) geomembrane of 1 to 1.5 mm thickness and the tubes and assemblies are made of hydraulic and sanitary PVC. The Biobolsa has 11 base sizes of reactors, with capacity to operate from 4 m3 to 40 m3 of liquid phase. The dimensions for each base size can be found in the company's catalog.
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, and 3 After 180 days, technical visit with an evaluation of adoption and impact.
Sistema Biobolsa provides a replacement service.
The Biobolsa lasts over 15 years. The geo-membrane, tested in lab under UV radiations, has an estimated lifetime of 50 years.interview with manufacturer in 2018 There is 1 year warranty on any manufacturing defect. Manufacturers also provide 20 year warranty on the geo-membrane.
Manufacturer Specified Performance Parameters
Performance targets are established depending on the climate and the type of animal manure used. Manufacturers specify the following target gas production: 14.6 m3, 9.7 m3, 5.8 m3 for the 40 m3 size for the following climate conditions: hot climate (>23°C), temperate climate (15°C to 22°C) cold climate (<15°C) respectively. The manufacturers have a Sizing Table available so that end users can look for their best size option and production.
Vetted Performance Status
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.
Complementary Technical Systems
The company also offers other products that can be adapted to use the biogas produced by the Biobolsa like burners, stoves, water heaters and biogas motors.

Compliance with regulations
Sistema Biobolsa is certified by B-Corporations. It also has the IS0 9001 certification.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. 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).
