In the documentary 

In front of citizens!

, Céline Crespy meets people who act to, sort, limit or transform our waste. Among them, 24-year-old Alexandra Neyroud, who in January 2019 created the Recycling association which organizes the collection of compost from individuals in the center of Bordeaux. The documentary will air this Wednesday at 8:30 p.m. on LCP. 

She grew up in the countryside where compost was the rule so when she arrives in town for her studies, it is reluctantly that Alexandra Neyroud throws her peelings with the general public.

The idea of ​​organizing composting in an urban environment was born during his Masters in development economics at the University of Bordeaux.

It carried out the first collection tests in September 2018 and the Recup association was launched three months later.

Today it has 500 members and collected 50 tonnes of bio-waste in 2020, which is recovered on agricultural land in Gironde. 

A "bokashi" bucket

The organic matter that decomposes attracts pests and when you live in the city, without a garden or with a small exterior, this is an aspect that can quickly discourage goodwill. This is the reason why the association distributes and collects bio-waste in a bucket called bokashi. "Bokashi is a Japanese method, it means well fermented material," explains Alexandra Neyroud. Instead of letting the material rot, we will add wheat bran enriched in microorganisms: these are fungi, bacteria and lactic acids that will ferment it. "

It works the same way as sauerkraut or beer and helps limit putrefaction and odors.

The mixture is to be sprinkled between each layer of waste and it is then necessary to tamp down a little to ensure the proper development of these bacteria.

"We can thus keep the bucket for several weeks at home [three weeks to a month on average] without having to find a container to empty it every three days because there are midges or it smells bad", assures the young woman.

The annual subscription amounts to 72 euros per year, and opens to participation in the board of directors if members so wish.

The collection of buckets, which is done by tricycle, is charged four euros for each passage. 

"Relevant" in the hypercentre

For the moment, the volumes treated by the association, 50 tonnes, are a "small drop in water", comments Alexandra Neyroud, compared to the 87,000 tonnes produced each year in the metropolis. From December 31, 2023, the regulations will change and the sorting of bio-waste will become compulsory. The association will be very attentive to the road map of the metropolis on the subject. She hopes that if public contracts are launched, she will be able to answer them "in any case on the hypercentre where we find that we are relevant", she specifies. 

Incentive pricing, which has been tested on a small scale in the metropolis, "could be a very good lever to convert more people to sorting biowaste," says Alexandra Neyroud.

For now, its customers are often already aware of ecological issues and often young parents.

In any case, they will have taken a step ahead, before the regulatory obligation.
