These BTA AD plants are under conversion, expansion or under construction.
Once in operation together they will add further waste treatment and Wet AD capacity of additional 204.000 tons per year to the BTA facilities worldwide.
This corresponds - with approx. 80 kg of biowaste per inhabitant and year (assumption for Germany) - to a treatment capacity for 2.55 million inhabitants.
For comparison: Munich population 1 605 264 as of 31.07.2026
Ieper (Belgium)
AD Expansion Ieper
After being in operation since 2003, IVVO has decided to expand Ieper’s AD capacity with the installation of a 3rd digester.
BTA will be the technological partner for the integration of the reactor and the further optimization of the overall AD concept.
Ieper treats up to 50,000 tonnes per year of biowaste, including biowaste collected within the City of Brussels area.
Toronto Disco AD (Canada)
Toronto Expansion
CCI BioEnergy (CCI), BTAs licensee for North America, has signed an agreement with the City of Toronto for a major expansion of the City´s Disco Road Organics Processing Facility.
The project will increase the facility’s processing capacity from currently 75,000 tonnes per year to 125,000 tonnes per year of Source Separated Organics (SSO), with a peak capacity of 140,000 tonnes per year.
Olbia (Italy)
Compact now also in Italy!
BTA Italia had been selected by the Italian company SECIT as the technology provider for the design, installation, commissioning and start-up of the wet Anaerobic Digestion Plant Olbia (Sardinia/Italy).
Olbia, the latest wet AD plant acc. to the BTA® process, and the 2nd on Sardinia, will treat up to nearly 40.000 tons of biowastes per year once operational.
Olbia will be also BTA’s first COMPACT SERIES installation in Italy.
The 2x BTA Compact Series will allow SECIT to meet the very limited space available on site, plus the very challenging project time schedule and budget.
Granollers (Spain)
BTAs next AD plant expansion!
BTA has been awarded with the contract to expand the AD facility Granollers (Spain).
In Granollers, in the 1st phase, the treatment capacity will nearly double to 80,000 tons per year. In the 2nd phase, capacity will be further expanded to the maximum of 100,000 tons per year.
There will be two separate treatment lines for different biowaste qualities.
The plant near Barcelona, designed for 45,000 tons of biowaste per year, was commissioned in 2010.
Following the successfull refurbishment of the EcoParc I in Barcelona, Granollers was the second BTA plant in Spain.
In the course of the expansion, during phase 1 the BTA hydromechanical pre-treatment system will be rebuilt and expanded, a second digestion line will be added, the dewatering capacity will be doubled, a partial stream sanitation will be provided and the process water management will be adapted.
BTA signs responsible for the engineering, procurement, rebuild and installation of the electromechanical installation work, the steel structures and the piping, as well as for the commissioning of the equipment and the adaptation and upgrade of the plant´s control system.
In the phase 2 an additional 3rd digester will be added.
After Castelleone (ITA) and Valorlis (POR), Granollers marks BTAs 3rd AD plant expansion in 2023!

Gennevilliers (France)
Second BTA biomethanation project in France
Jointly managed by Syctom (l'agence métropolitaine des déchets ménagers Île-de-France) and Sigeif(Service public du gaz, de l'électricité et des énergies locales en Île-de-France), the biomethanation project at the port of Gennevilliers (Hauts-de-Seine department) aims to process up to 50,000 tons of food waste annually generated on Syctom's territory.
Following a call for tenders in 2020, Syctom and Sigeif decided in March 2022 to award the concession for the design, construction, financing, operation and maintenance of the biowaste methanation plant to Paprec (https://www.paprec.com/en).
The biomethane produced from the organic waste will supply Sem Sigeif Mobilités' largest French Bio-GNV fueling station, also located in the port of Gennevilliers. The biogas will help to reduce the need for imported fossil fuels.
The digestate from the methanation will be used as fertilizer and transported away by water for agricultural use.
PAPREC has selected BTA & AR-Val S as technology partners for the project.
BTA and AR-VAL S are responsible for the design, supply, assembly and commissioning of the major part of the process, starting with the waste reception, storage and feeding, the BTA hydro-mechanical pre-treatment, the wet anaerobic digestion incl. sanitation and heat recovery and dewatering as well as the biogas valorisation.
