The neighborhood associations and entities that They have been pursuing legal proceedings for six years regarding air pollution from the Besòs waste incinerator plant. They requested that, in the trial, the plant's operations manager, FR, face a four-year prison sentence for a crime against natural resources and the environment that poses a serious risk to public health. With a request mirroring that of the Public Prosecutor's Office, the Airenet platform maintains that FR—who held the technical and operational management position at the Tersa plant—"allowed and consented to the plant operating systematically outside the parameters required by environmental regulations and tolerated the abnormal functioning of the facilities, which generated a serious risk to people."

There are reasons to continue investigating whether the activity of the Besòs waste incinerator has polluted the air and harmed the health of the residents of the area between 2015 and 2019. With this argument, the Barcelona Court has decided to reopen the case against the Tersa plant for an alleged crime against natural resources and the environment. The case had been provisionally closed in May by Badalona's Investigating Court No. 5, considering that Tersa had not engaged in "any criminally unlawful conduct." Now, however, the Court concludes that the closing was "premature" and orders a trial to assess whether the plant incinerated urban waste at temperatures below 850 degrees—the only way to destroy pollutants without affecting the atmosphere—and whether it emitted chemicals harmful to human health.
