The EU is taking Italy to court for its failure to sort out or close down 44 unsafe landfill sites.
Despite earlier warnings, the country has failed to take action, despite suggestions the facilities could pose serious risks for human health and the environment.
Like other Member States, Italy was obliged to either rehabilitate existing and permit-granted landfills by 16 July 2009, by bringing them up to the safety standards or by closing them.
Due to insufficient progress, the EU chased Italy up in June 2015, urging the nation to adequately treat 50 sites.
In spite of some progress made, the necessary measures to upgrade or close 44 landfills were still not completed by May 2017, prompting the legal action.
A renewable trade body has launched a new group to cater for the landfill gas sector.
The EU has also launched legal action against Italy for failing to respond to allegations of emissions test cheating by Fiat Chrysler.
