Biogas for your farm

Biodigesters for farms from 2 to 200 cows.

A Sistema.bio farm digester is a prefabricated reactor bag, not a septic tank: feed it manure and water daily and it returns biogas for cooking and digestate for fertilizing. It suits farms from 2 cows or 5 pigs up to agribusiness. We install in Panama and assess projects abroad. Over 159,000 systems installed in 35 countries (source: Sistema.bio).

Biol + biochar

Liquid fertilizer goes further when the soil holds it.

The biodigester gives you biofertilizer every day. Biochar keeps that fertilizer at the root instead of washing away with the rain. Sistema.bio recommends it in its own video series for fruit trees.

Frequently asked questions

Before buying

Is a farm biodigester the same as a septic tank?
No. A septic tank only treats household wastewater and wastes the gas. A farm biogas digester like Sistema.bio takes in cattle or pig manure daily, captures biogas in a sealed reactor for cooking or water heating, and returns digestate, a liquid biofertilizer.
How much does a biodigester cost? Is there financing?
The price depends on the reactor size and includes a farm assessment, installation, training, reactor, stove, burner and customer support. Message us on WhatsApp with how many animals you have and we'll quote the same day. Financing options exist subject to eligibility.
How many animals do I need for a biodigester?
As few as 2 medium cows or 5 pigs: the minimum is about 36 kg (80 lb) of fresh manure a day. Multi-reactor setups serve farms with 200+ animals. Cattle and pig manure work best; goats, sheep, horses, rabbits, poultry and crop waste also work.
What is it made of and how long does it last?
UV-resistant linear low-density polyethylene (LLDPE), with hydraulic PVC piping. 20 to 25-year lifespan. 10-year warranty on the reactor.
Is biogas safe? Can it explode?
Yes, when properly installed. Biogas sits at low pressure in the reactor (it is not compressed like bottled LPG), and the system has a relief valve, water traps and an H₂S filter. Use normal gas-stove care: ventilation and no open flames near the reactor. Training is included.
Does a biodigester smell? Is cooking with biogas hygienic?
Far less than open manure: the reactor is sealed and a filter removes H₂S (the rotten-egg smell) before the stove. The flame burns clean and leaves no taste or smell on food. Any odor is limited to the inlet while you feed it.
Can I use my usual LPG (tank) stove?
No. Biogas needs its own wider piping and a stove designed for biogas. Both come in the package.
How long does installation take? And when is there gas?
One day for Sistema 6 to 20 (reactor, gas line and stove). The biodigester inflates and starts producing gas 21 to 30 days after the initial load.
Is maintenance difficult?
No. Any adult can do it: feed it daily with manure and water, empty the water traps and check the filter. If you stop feeding it for a month, it restarts when you load it again (stir well).
What is digestate (biol) and how do I use it?
Digestate, called biol in Latin America, is the liquid leaving the digester: digested manure with plant-available nitrogen, phosphorus and potassium and far less odor than raw manure. Apply it diluted via irrigation, foliar spray, on seeds, orchards and pasture. Includes a 5–7 day tank.
Do you sell Sistema.bio digesters outside Panama?
We are Sistema.bio's official distributor in Panama and assess projects in other countries case by case: we size the system and coordinate supply, installation and training, directly or through Sistema.bio's local network. Tell us your location and herd size.
