Portable Biomass Anaerobic Digesters Turn Food Waste into Energy Biogas and Organic Fertilizer

The unit can produce up to about 1.8 m³ of biogas per day under optimal conditions.

Total internal volume is 2.65 m³. The product is a portable membrane digester bag with an integrated gas storage bag mounted on a support frame.

It's intended for household organic waste such as food scraps, vegetable peelings and similar biodegradable kitchen waste. Small amounts of animal manure can be used. Avoid large bone pieces, excessive fats/oils or non-biodegradable materials.

Biogas is suitable for cooking (e.g., a double-burner biogas stove) and can also be used for small-scale power generation with appropriate equipment. At maximum output it can run one burner for around 4 hours per day (depending on cooking intensity).

The digester produces bio-slurry (liquid organic fertilizer). This is a nutrient-rich, clean liquid fertilizer suitable for agricultural or garden use after appropriate dilution and testing for nutrient content.

The minimum recommended ambient temperature is 10°C. Biogas production will slow below this temperature; performance improves at warmer temperatures.

The system includes a membrane digester bag combined with a gas storage bag, a support frame, a feed pump, a slurry outlet, a biogas filter to clean the gas, and a biogas pump to supply pressure to the stove.

The digester bag is made of a specialized material that is anti-aging, resistant to acids and alkalis, and UV-proof, designed for long-term outdoor use. Actual lifespan depends on exposure and maintenance.

Start-up time varies with temperature and feedstock; under suitable conditions you may see gas production within days to a few weeks. Stable, maximal production often takes longer as the microbial community establishes.

Regular tasks include feeding with appropriate organic waste, checking and cleaning the biogas filter and pump, inspecting the bag and frame for damage, and periodically removing excess slurry. Frequency depends on use, but weekly visual checks are recommended.

Treat biogas as a flammable gas: ensure good ventilation, check for leaks regularly, avoid open flames/sparks near storage and piping, install gas-tight connections, and use a certified biogas stove or burner. Follow local codes for gas appliance use.

Check feedstock quality and quantity, ensure ambient temperature is above 10°C, inspect for leaks in piping or the bag, verify pumps and filters are functioning, and avoid overloading with fats or non-degradable waste. If problems persist, consult the supplier for troubleshooting.

The system includes a biogas filter that removes impurities and moisture to provide cleaner gas for cooking and small-scale appliances. Filters should be inspected and maintained per supplier instructions.

Yes — it is a light household biogas plant designed to be portable and is suitable for off-grid situations. It requires regular feeding and basic maintenance but does not need grid gas supply.

Multiple units can be deployed in parallel for increased capacity. For significantly larger or commercial-scale needs, consult the manufacturer or an installer to design an appropriately sized system.
