“An incinerator for the metropolitan city of Rome is needed, with a dimension to be carefully evaluated, and, above all, together with a program of concrete measures for prevention, the increase in separate collections and recycling”. Like this Edo Ronchi, president of the Foundation for Sustainable Development.
“The metropolitan city of Rome (the province) has 4.2 million inhabitants and produced 2,158,000 tons of waste in 2020. In 2021, waste production increased to about 2,250,000 (non-definitive estimate). Separate collection is very low and does not grow: it is 50.4% equal to 1,089,000 tons. The waste to be disposed of from separate collections is 13-14% – he explains – the residue of the recycling activities to be disposed of (varies with the type, the most consistent is that of mixed plastics), by weight it is no less than 10% of the waste sent for recycling. So, between impurities from separate collections and waste from recycling we have at least 200-230 thousand tons to be disposed of in the province of Rome“.
“Then there is the waste that remains from the mechanical and mechanical-biological treatment plants of undifferentiated waste. At least half of the unsorted waste leaves the treatment plants either as ‘dry’, to be sent for energy recovery, or as waste to be disposed of: no less than another 4-500 thousand tons in total. In the province of Rome there are no incinerators and the landfills (Colleferro and Civitavecchia) are now almost exhausted. These are the facts and the starting numbers “, he clarifies.
“The metropolitan city of Rome (the province of Rome), the largest Italian province with the highest concentration of municipal waste production, is significantly delayed in separate collection and has a shortage of personnel recycling plants and a significant problem of disposal of the residual share from separate collection, from recycling and from the treatment of unsorted waste – continues Ronchi – What to do with this share? increasing and improving recycling, especially of the organic fraction (which for more than half is now sent outside the Region). These measures should not only be written on paper, but practiced. Furthermore, we must also deal with the transitional phase and what to do if the objectives of reducing the waste to be disposed of are not achieved “.
“In this populous province with a consistent production of waste, the residual amount of waste to be disposed of would remain substantial even if the measures to reduce it were successful – he clarifies – And since no one can make it disappear, only a few solutions remain: either it should be disposed of elsewhere, in other regions or abroad, or new landfills must be opened or an incinerator is used. Moving the problem elsewhere is never a solution and landfills, due to specific European regulations, must be reduced to a minimum, not more than 10% of the waste produced. If things are done properly, the amount to be disposed of may be less than the 600 thousand tons envisaged by the proposed incinerator but a significant quantity remains, to be defined with precise analyzes and defining new measures and evaluating the impacts of the measures adopted “.
So “an incinerator for the Province of Rome, given the large amount of waste produced, is needed, but only together with a program of measures on all aspects of waste production and managementwith a more careful and well-founded evaluation of the quantity to be disposed of and the technology to be used “.
