Brussels, September 15, 2023. The depletion of the ozone layer is an ongoing issue in our times and a challenge to address in the ecological transition. That’s why today, from LIFE ECOdigestion 2.0, we join the global community to emphasize the importance of protecting the ozone layer on International Day for the Preservation of the Ozone Layer.

The ozone layer, located in the upper atmosphere (stratosphere) of Earth, serves the purpose of blocking the sun’s ultraviolet radiation, which can be highly harmful to the living organisms on Earth. The “ozone hole,” recognized in 1985, is the result of human emissions of chlorofluorocarbons (CFCs), which are a group of chemicals that deplete the ozone layer and greenhouse gases present in, for example, aerosols. Since the signing of the Montreal Protocol in 1987 and its subsequent amendments, progressive elimination of up to 96 chemical substances was promoted to mitigate this impact.

In this regard, how does biogas production contribute to ozone layer protection?

The Role of LIFE ECOdigestion 2.0 in Protecting the Ozone Layer

LIFE ECOdigestion 2.0 project plays a significant role in preserving the ozone layer by actively promoting the production and use of renewable energy sources. Among these sources, biogas production stands out as one of the most environmentally friendly methods for energy generation today. In addition to its environmental benefits, biogas production also plays a key role in efficient waste management and promoting a circular economy, as it can become a valuable fuel source for vehicles.

The capacity to transfer this technology to other projects and sectors is an essential component of the project and its collaborators’ commitment to promote a sustainable environment and adopt practices that adapt to the challenges of climate change.


LIFE ECOdigestion 2.0 is a pilot demonstration project, funded by LIFE Programme and with a budget of more than 970,000 EUR, which generates biogas in sewage treatment plant digesters by mixing putrescible organic waste (slurry, poultry, organic fractions, MSW, horeca, etc.), thus transforming sewage sludge into green energy through technology. The initiative led by Global Omnium, (Spain), in collaboration with the Finnova Foundation (Belgium) and Águas do Centro Litoral (Portugal) aims to become the most versatile digestion control tool on the market, achieving environmental and economic benefits through the production of biogas by making optimal use of waste. Thanks to this technology, it favours the reduction of greenhouse gas emissions and the use of sewage sludge generated in wastewater treatment processes, thus achieving a positive impact on the environment. This programme is easily scalable with other funds such as FEDER, NextGenerationEU or Repower EU.
