Manufacturer Specified Performance Parameters
This plant was designed to make gas production efficient, be convenient for transport, and easy to install.
Vetted Performance Status
Testing of the product was done by Shenzhen USG Labs, the verdict was that the biodigester is capable of converting organic waste into biogas.
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. Biogas storage & production bag is made of macromolecular structure polylayer design, therefore there is no leaking risk.
