BIOGNVAL: Innovative technology to serve the energy transition

Mitigating climate change requires the involvement of local partners to produce innovative, green energy sources that are capable of meeting local needs.

The BIOGNVAL project developed in Valenton, Ile de France, is a new solution enabling the recovery of biogas from the purification of sludge.
 The project was launched in February 2013 to satisfy the needs of SUEZ customer SIAAP. Undertaken by SUEZ and SIAAP with support from ADEME (French Environment and Energy Management Agency), the project welcomed a multitude of partners from varied yet complementary fields, such as the start-up Cryo Pur, Thermoking or the Engie Group and vehicle maker Iveco.

Continuing on from COP21 in its climate centric efforts and in line with its commitment to the circular economy, the SUEZ group intends to promote the development of new energy sources. The BIOGNVAL project, which represents a genuine innovation that can boost the attractiveness of regions and the performance of industrials.

The BIOGNVAL project transforms biogas from residual sludge into a renewable and easily storable energy: liquid biofuel.

The transformation requires two steps: the biogas is purified to produce biomethane, then this biomethane is liquefied so it can be used as a fuel for all long distance goods vehicles and passenger transport vehicles.

Liquefied biomethane or BioLNG is easy to store and transport, as liquefaction reduces its volume by 600. It offers many opportunities both for transport services (fuel for heavy goods vehicles and buses) and for industrials who can use it as fuel.

The processing plant in Valenton also produces and liquefies BioCO2. This liquid BioCO2 can be used for industrial purposes, notably in the frozen and refrigerated food sector, but also for agricultural purposes (greenhouses), the food industry (sparkling drinks) and the chemical industry (ether, alcohol, etc.).

The BIOGNVAL project demonstrates that from our wastewater, we can produce a clean fuel that emits no fine particles and practically no nitrogen oxides, generates 50 % less noise than diesel engines and offers an 80 % reduction in CO2 emissions.

Each year, the wastewater for 100,000 inhabitants would produce sufficient BioLNG to supply 20 buses or 20 trucks.

The objectives set by the European Union are to achieve a 10 % level of renewable energy in the transport sector energy mix by 2030 and to reduce greenhouse gas emissions by 20 % by 2020.
