Genoa – Increase separate collection, reduce the production of urban waste and a new plant that enhances undifferentiated waste. It was approved today by the Ligurian regional council, on the proposal of the regional councilor for the waste cycle Giacomo Giampedrone, the new waste management and remediation plan which aims to close the cycle at the regional level.
After approval by the Executive, the public consultation phase of the Strategic Environmental Assessment will start shortly, during which anyone can submit comments. The phase will last 45 days from the publication of the official notice. After this phase the new document will be brought to the council for the definitive proposal to the council. The new plan, which will remain valid until 2026, replaces the previous one from 2015.
The new waste plan aims for a reduction at the source of the production of urban waste (-4% by 2026) and to further increase separate waste collection (the aim is to reach at least 67% again in 2026), with new prevention actions and the promotion of punctual pricing. It also provides for the substantial confirmation of the plant structure for the treatment of undifferentiated, centered on the 4 poles of Colli (Imperia), Boscaccio (Savona), Scarpino (Genoa) and Saliceti (La Spezia), and for the recovery of the organic fraction for to which the biodigesters of Colli and Saliceti have already been authorized and the Cairo Montenotte plant is already operational.
The document also provides a new regional plant that enhances the undifferentiated waste leaving the mechanical biological treatment plants, preferably by means of a “waste to chemical” approach, that is producing hydrogen and methanol that they can be used in green districts, with a strong decarbonisation effect; alternatively, energy enhancement technologies will be evaluated.
In fact, the objective is to valorise such waste for making landfill a residual tool and take the decisive step towards closing the cycle at the regional level, avoiding the sending of waste outside the region, minimizing environmental impacts and optimizing costs. The plan does not locate the new plant, for which specific financing channels will be required, but defines the location criteria that will be the basis for the future choice of the site in agreement with the interested entities. As regards special waste, the new Plan provides for new actions on the subject of inert waste, construction and demolition waste and excavated earth and rocks, as well as paths to find local solutions for waste streams such as sewage sludge or medical waste. the latter made even more pressing by the Covid-19 pandemic.
On the subject of remediation of particular importance is the re-measurement and administrative reorganization of the Site of regional interest (Sir) of Pitelli, formerly Site of national interest (Sin). The re-measurement, much awaited by the territory, starts from the recognition of surveys, studies, monitoring and interventions that for over twenty years have allowed to deepen the knowledge on the state of contamination of a vast area in the municipalities of Arcola, La Spezia and Lerici, known to the chronicles for a series of episodes of mismanagement of waste between the 70s and 80s, has the effect of an administrative simplification for the activities to be carried out in the areas concerned and allows the activities of the Liguria Region to be concentrated on the areas that were actually contaminated and not still reclaimed.
With the new perimeter, all areas that, on the basis of the investigations carried out, are not contaminated, the sites that have completed the remediation work and are certified by the Province as well as the marine areas of the Sir, are excluded from the perimeter of the SIR, with the exception of of the stretches of water for which a remediation procedure has already been initiated. “This new plan starts from the results obtained in recent years, when we have passed from one archaic situation, as defined by the bicameral commission of inquiry on the waste cycle in 2014, to a new modern system capable of enhancing the various flows and in which many plants have already been authorized “, explains the regional councilor for the waste cycle Giacomo Giampedrone.
“On the front of separate collection there was a trend of constant increase in recent years, growing from 32.02% in 2012 to 53.43% in 2019. The recycling rate of all the main fractions has also grown in the last three years with an excellent performance on glass (96%) and wood (90% ) and good results for paper (75%) “, summarizes Giampedrone.
“Now we have to take a further step forward: not only are we confirming the plant structure for the current province, but we are also planning a further plant to enhance the flows that now go to landfills, preferably a chemical recycling plant of the dry part of municipal solid waste which at the moment is still going to landfill. A structure at the service of the whole region in a barycentric former industrial area “. The Region” is already taking action to identify the resources to build it. The financial requirements for remediation interventions have also been updated, so that it will also be possible to access Pnrr resources “.
