Les Champs-Élysées go circular. The city of Paris starts separately collecting organic waste
Finally! Paris is moving in the right direction by giving inhabitants of the city the means to take a new step in sorting and recycling. Since May 4, 2017, the French capital has started implementing an ambitious project to boost circular economy involving the source separation by households of organic waste in the Second and Twelfth Arrondisments. This action is part of the overall project for waste reduction and recycling, to which the city committed in 2014. The targets to achieve are the following: reducing by 10% by weight the quantity of generated waste between 2010 and 2020 and increasing recycling from 15% to more than 50%.
As part of its Recovery Plan for sorting, the City has been conducting a massive policy for two years to strengthen the means to facilitate the sorting of Parisians by giving them more solutions (Installation of several thousand additional sorting bins in garbage rooms) and increasing awareness of them (updating of instructions, dissemination of a new sorting guide, awareness-raising campaigns).
Who are the actors implementing food waste separate collection?
- Council of Paris: Anne Hidalgo, Mayor of Paris; Mao Peninou, assistant in charge of cleanliness, sanitation, organisation and operation of the Paris Council
- Mayors of the Second and Twelfth Arrondissements, Catherine Jacques Boutault and Baratti-Elbaz
- Syctom, the largest European waste treatment and recycling organisation, who have previously been involved in expensive and unnecessary infrastructure spending such as the renovation of the Ivry incinerator in Paris.
- ADEME, the French agency for the environmental protection
- Réseau Compostplus, the French network of bio-waste treatment facilities
- Novamont, a leading company in the field of bioplastics.
How does it work?
The food discards of Parisians (from meal preparation to leftovers, and unused food still in packaging) is about 160,000 tons a year, or nearly ¼ of the content of the residual waste bin. This waste was until recently only collected mixed in with the general waste and was subsequently disposed of by incineration. The objective is now to collect this portion separately to be used in biogas and/or compost.
3,205 trays with brown lids (741 in the 2nd and 2,464 in the 12th) have been distributed in all the buildings which have been identified as suitable. Other buildings will be dealt with at a later date. Basically, the project involves 74,161 flats located in 4,361 buildings covering around 120,000 people. the participating households have also been provided with new bags for the collection of food waste. These new bags are biodegradable according to the European standard EN 13432 and are made in Mater-Bi, a bio-plastic developed by Novamont.
For years, Paris has been lagging behind in terms of waste management best practice, and Zero Waste France, a member of Zero Waste Europe has been at the forefront of the campaign to change their course towards Zero Waste. This has included an incredibly visual campaign against the renovation of the Ivry incinerator in the city, where they proposed an alternative ‘Plan B’om’ for the city. It is clear that Paris still has a long way to go to develop effective and circular waste management practices but this is a step in the right direction.
Food waste, and other biowaste is one of the most problematic waste streams, and even more so when it is not separated at source. Biowaste, if not effectively separated can contaminate other recyclable materials and if landfilled it can produce greenhouse gases and toxic leachate. Our reports have demonstrated that the incineration of biomass in so-called waste-to-energy plants cannot be considered ‘carbon neutral’ as it is in many accounting systems and is a key contributor to greenhouse gas emissions. . Indeed, if food waste was a country, it has been calculated that it would be the third largest “emitter” of CO2 worldwide, just behind the USA and China. Furthermore, around 88 million tons of food are wasted annually in the EU, with associated costs estimated at 143 billion euros. Hence, keeping separately the collection of food waste allows to achieve several benefits both in term of money savings, energy efficiency and the circular economy.
We can minimise the environmental impact of the food we eat by ensuring separate collection. On the contrary it represents a reliable source of nutrients for our land and for the soil. After collected, bio-waste can be sent to composting. Natural compost is a soil improver that is preferable than synthetic because is toxic free and possess all the necessary nutrients. Furthermore, bio-waste from the city of Paris will be used for the production of bio-gas reducing dependency on fossil fuels. Anaerobic digestion is used to generate biogas which is used as a source of energy to produce heat and electricity resold on the grid or, after purification, to become biomethane, a fuel used to drive vehicles.
This project in Paris follows the example of the city of Milan, the 1st big city worldwide to organise kerbside collection of biowaste and could become another example of the feasibility of organising separate collection in a densely populated city and implementing sustainable collection of biowaste.
In this, Paris might still have a long way to go but they are going in the right direction.
