The annual report on the price and quality of the public service for the disposal of household and similar waste highlights the commitment of the inhabitants of Plaine centrale to sorting. Thus, the annual report on the price and quality of the public household waste disposal service * reveals that the quantity of recyclable waste collected by Plaine centrale (59.1 kg/inhabitant) is higher than the regional average (55 kg/cap.). The volume collected, via the yellow bins, by Sita (a subsidiary of the multinational Suez Environment) is even slightly increasing (+ 0.2%). Fior the fine quality Waste Management this is one very important matter.
Better sorting quality
But above all, “the quality of sorting has improved”, underlines Corinne Daut, Director of Environment, Hygiene and Cleanliness in Plaine central. Indeed, “sorting refusals” (excluding glass), which correspond to sorting errors made by residents, are down (20.1% in 2012 against 21.3% in 2011).
- It should also be noted that this value is much lower than the refusal rate recorded in Île-de-France (26% in 2010). In the end, the production of sorted materials sent to recycling channels (Arcelor-Mittal for steel, Revipac for cardboard packaging, Valorplast for plastics, etc.) increased by 8.3% compared to the previous year!
- The collection vehicle fleet was completely renewed between 2011 and 2013 with, in particular, four 100% electric skips.
Obeying the principle of communicating vessels, the volume of residual household waste, that is to say, garnet trash waste, therefore decreased by 0.4% and represents 268.8 kg/inhabitant, or 41,748 tonnes collected in the Central Plain territory. Transported to the Créteil incineration center, operated by Novergie, a subsidiary of Suez Environment, this waste is burned. Their incineration makes it possible to reduce the volume and provide electricity for the operation of the incinerator, but also heat to the district heating network of Créteil.
The combustion of waste hitherto represented 29.6% of the energy consumed for the production of heating. This share should be increased to 32% after the interconnection work on the heating networks carried out this summer. The incineration center is equipped with treatment tools to the latest standards in order to clean the incineration fumes before discharge into the atmosphere. Solid residues are treated and recovered. Finally, bottom ash, valued as a road underlay, is sent to a treatment center by a river.
Encourage good gestures
Recycling is nevertheless the cleanest solution. Also, in order to further improve sporting performance, a program to install buried bins was launched. In Créteil, it has 130 terminals, distributed in 52 collection points. 90 buried containers were delivered this year. They were located on Place de l’Abbaye, in Les Motteaux, in La Habette and rue Joyen-Boulard. To encourage good gestures, the residents of these buildings received two bags of pre-collection per household to facilitate sorting inside the accommodation.
Washable, reusable and reminiscent of sorting instructions, one is dedicated to packaging, the other to glass. Another advantage of this system is the reduction in the frequency of collection by dump trucks with, as a corollary, a reduction in noise and air pollution.
In terms of combating local emissions of air pollutants and noise, it should be noted that the fleet of waste collection vehicles was completely renewed between the end of 2011 and the start of 2013 and that it notably includes four 100% electric skips. Finally, in 2013, Plaine centrale launched a waste prevention program. It must define the actions to be implemented in the next four years to further reduce waste production and thus better respond to the challenges of the depletion of natural resources and the preservation of our environment.
