Shenzhen Puxin Science & Technology Co.
Puxin PX-ABS-3.4M3 is a biogas digester that converts organic waste, animal, or human manure into biogas and organic fertilizer.
Puxin biogas system is a family-size digester that converts organic waste, animal, or human manure into biogas and organic fertilizer. The biogas digester is also removable and can be combined with different fertilizer types. The unit is distributed as a Do It Yourself Kit biogas system. The generated biogas can be used for cooking, water heating, and generating electricity. See this video of the product.

Puxin biogas units 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.

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.
Other related products can be added – not included in the unit price:
1. Feeding pump for sewage sludge disposal
2. Circulating pump for raw material feeding and anaerobic digestate mixing
3. Grinder for food waste shredding
4. Electric heater can be added for cold regions
5. Biogas stove, biogas rice cooker, biogas generator, etc
The product has the ISO 12100 certification
Each digester will be installed and inspected after manufacturing. Before sending it to Puxin, the factory will conduct a second inspection. Once the product has arrived at the company, the company’s technicians also need to install and check again.Interview with representative
