The collection of food waste is expanding to new municipalities and a new sector of Grenoble. From 27 September, it will concern Fontaine and sector 3 of Grenoble (the Eaux Claires, Mistral, Rondeau districts and west of Rue Général Mangin). From 11 October, it will also include Seyssinet-Pariset and, lastly, Sassenage from 18 October.

Inhabitants will receive a sorting kit free of charge, comprising an individual biobucket, a sorting guide and a roll of compostable bags for collecting their food waste (more bags can then be collected from the distribution points indicated in the booklet entitled Food Waste Collection Days and Compostable Bag Distribution Points for each municipality). The Metropole is also providing a brown bin to collect the waste bags and is setting up a new weekly collection round.

Biogas production

What kind of waste does this new type of collection concern? Peelings, preparations and leftovers, coffee grounds and filters, old bread, out-of-date food (without packaging), teabags, etc. Food waste represents around one-third of household waste in terms of weight. In the Grenoble Metropole, this is equivalent to 27,000 tonnes per year, i.e. approximately 60kg per inhabitant.

Why collect it ? Firstly, because it makes it possible to reduce the volume of household waste. Also, because this waste can be recycled, in other words transformed to produce compost or biogas.

By 2024, the Murianette composting centre, which already produces compost from collected food waste, will be equipped with a new methanisation facility, making it possible to produce more biogas to power the Metropole's buses and waste removal trucks. This in turn will make it possible save money and protect the environment.

Good habits

To avoid inconveniences (smell, flies, etc.) you are advised to :
• Throw the compostable bags in the brown bin regularly (even if not full)
• Close the biobucket lid properly
• Keep the biobucket clean (dishwasher friendly)
• Clean the brown bin and put it out for collection every week
