Biogas digester leasing: your waste, our plant, a 10-year contract
A containerised anaerobic digester on your site, financed and operated by REURASIA under a 10-year lease. You supply the waste and take the gas or power.
The problem it answers
Sites with a steady stream of organic waste pay twice: once to dispose of it, and again for the energy they buy while the waste's own energy content goes to the landfill. The obstacle to fixing this is capital. A digester is a multi-year infrastructure decision most operating budgets cannot absorb.
What we do
We deploy containerised anaerobic digestion on your site under a 10-year lease. We finance, build and operate the unit; you supply the waste and take the energy. Your upfront cost approaches zero, and our return depends on the plant performing, which is the alignment you want from an operator.
It is not the answer for every site, and we will say so. Composition decides it more than tonnage. A consistent stream of digestible organics that you control can make sense at about 2,000 tonnes a year; a large stream of the wrong material never will. Where digestion is not the right route, the same data usually points to one that is: composting, co-digestion, thermal, or an audit first.
What qualification looks like
Before anyone talks equipment, we ask for the data that decides the case: what the waste is, how much and how consistently, what you pay to dispose of it today, what energy the site uses, and what space and permits look like. If those numbers support a plant, the next step is a paid pre-feasibility that both sides can rely on.

What we need from you
Six items decide whether a lease can be sized. With them, the answer takes a week.
- Waste type and composition, with a recent analysis if one exists
- Tonnes per year, and how it varies across the week and the season
- What you pay to dispose of it today, per tonne and per year
- The site's electricity and fuel bills for the last twelve months
- A site plan showing 600 square metres of hardstanding with power and water
- The ECC and any discharge or air permits the site holds
Questions buyers ask
How is a digester lease sized, and who carries the capital cost?
REURASIA finances, builds and operates the digester on your site under a 10-year lease. You supply the waste and take the gas or power; we carry the capital cost. We prefer about 2,000 t/yr of digestible organics or more. We publish no prices; the paid pre-feasibility gives the figure for your site.
Send us the six-item checklist on this page.
Food-processing waste: does a lease fit a food plant?
Yes, if the plant has a steady stream of digestible organics at about 2,000 t/yr or more. It takes the organic fraction only, not packaging, plastics or sweepings. Where composition is uncertain, a paid audit comes first. Biosfair uses the same technology, at a landfill rather than a food plant.
Send us: the organic waste and tonnes a year, how consistent it is, hauler and landfill cost per tonne.

Distillery vinasse (spent wash, stillage) and press mud: can they be digested?
Press mud and vinasse can both be digested; bagasse is burned, not digested. Digestion makes sense where volumes are steady enough to size a plant, with the off-season counted. REURASIA's sugar-mill reference is the HDJ Bayawan bagasse cogeneration plant; for vinasse the first step is the audit.
Send us: the volumes of press mud and vinasse leaving the site and where they go today, and what the DENR discharge permit requires.

Poultry, piggery and livestock manure: what digests and what does not?
Digestion or co-digestion works where moisture, contamination and volume support it. Dry broiler litter on its own composts or fires; it does not digest well without a wet co-substrate. For pig farms, sizing starts from the screening: head count, manure volumes and how the farm washes down. Odour and wastewater at source come first, energy second.
Send us: birds or head and housing system, how manure is collected and how wet it is, any lagoon or discharge permit.
Can a private landfill digest its organic waste?
Where the organic fraction can be separated, yes. A composition and tonnage study comes first, because the case rests on the separable digestible share. Mixed waste is not digested without separation. Biosfair's pilot digests about 2,150 t/yr, just above the 2,000 t/yr preferred minimum for a stand-alone lease. Results will be published after commissioning and independent verification.
Send us: tonnes per day, a composition survey, any separation today, the tipping fee and remaining airspace.
