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.

A containerised dry digester plant in operation: four modules, technical containers and gas holder, reference installation in France

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.

Support across the project lifecycle, from first screening to operating reality. A paid audit can end at Screen, with a recommendation not to build.

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

The first step

Tell us what organic waste the site produces and roughly how much. We respond with the qualification checklist.

Sectors where this is usually the right first step: food processors and industrial plants.

What the site produces, what you pay to dispose of it, and what you pay for energy. An engineer reads it and comes back with the first step.
