A modular approach
Containerised solutions for small feedstocks, designed to adapt to site constraints and local needs.
- Modular configuration.
- Sizing based on available inputs.
- Plant expansion studied with the project.
Solutions
A solution is sized.
Not imposed.
Containerised and hybrid anaerobic digestion units to treat biowaste where it is produced. A target design range from 500 kg to 10 t per day, depending on feedstock and feasibility.

An approach for larger feedstocks
A tank combined with containerised equipment to meet larger needs.
- Design tailored to the site.
- Heat and electricity needs integrated.
- Planned 10 t/day pilot in New Caledonia.

Producing in the right place.
For the right uses.
Cogeneration produces electricity and heat from biogas. By adding an absorption chiller driven by part of the recovered heat, trigeneration can also produce cooling.
Production and potential savings are sized according to the available feedstock and needs. Actual savings are assessed during the feasibility study.
A concrete example to study
The shopping centre's waste.
Energy for its shops.
Imagine a small unit located near a shopping centre's service area. Sorted organic waste from restaurants, the fruit and vegetable section and other compatible shops is carried a short distance to an enclosed reception area.
Powering the site
Supply part of the equipment and lighting, depending on output and grid connection arrangements.
Using recovered heat
Study hot water needs and other useful thermal uses, taking the process's own needs into account.
Cooling the spaces
Produce chilled water for air conditioning. Fresh counters and cold rooms require a study of temperatures and suitable equipment.
Savings to be built on site.
Shorter trips for locally treated waste and lower energy purchases can reduce site costs. The balance also takes into account investment, operation, maintenance and back-up needs.
Operating example, with no guaranteed output or savings. Available volumes, actual heat and cooling demand and site feasibility determine the project's value.
Odour control from the design stage
Treating in a closed loop.
Protecting the neighbours' comfort.
Anaerobic digestion takes place in a closed digester. For reception and handling operations, the design provides for closed containers, an enclosed area and air extraction with suitable treatment, for example a biofilter.
- Enclosed reception and controlled transfer.
- Closed digester and biogas circuits.
- Air captured and treated at sensitive points.
- Monitoring, upkeep and checks during operation.
Objective: avoid odour nuisance for local residents. The absence of odour cannot be guaranteed on the basis of a diagram alone: it depends on design, incoming materials and operation.

Pressed digestate ⇢ Drying option under study

Digestate is a second flow: its treatment and use are studied according to its characteristics and the applicable framework.
Treating inputs
Immediate treatment is preferred; storage is kept for emergency situations.
Adapting cogeneration
The site's needs guide the configuration. Adding digesters or gas storage is studied case by case.
Using the heat
The design includes studying digestate pressing and then drying using cogeneration heat.
Optional add-on modules
Going further
in resource recovery.
A scalable approach: depending on the project's needs and feasibility, add-on modules can be studied to broaden the resources recovered and local uses.
Opening new routes for wood and woody plants.
Dedicated treatment and recovery options for these materials, alongside the main process.
Capturing and using an additional resource.
CO₂ capture and recovery modules, studied to develop uses suited to the project.
Options studied case by case: their scope and integration conditions are defined during the project study.
A loop to develop
Anaerobic digestion meets seaweed farming.
Drawing on process resources
Study the use of heat and CO₂ from biogas recovery to support seaweed farming in a suitable system. Species selection and flow control are part of the design.
A biomass to characterise
Seaweed can also be studied as an anaerobic digestion input, depending on its composition, salinity and quality. Seaweed that has accumulated pollutants requires a dedicated route, defined after analysis.
This coupling is a development ambition, to be validated by trials and a feasibility study. It does not involve any direct discharge of digestate into the marine environment.
