Sictom du Marsan changes pace

EAre we taking out the black trash this week? This question will have to be asked in Mont-de-Marsan and Saint-Pierre-du-Mont (intra-ring districts) from the first months of 2025, when Sictom du Marsan, the union managing collection and processing waste, will establish a new pace of household waste collection.

Users’ bins will no longer be collected every week, but once every two weeks, like those for selective sorting. Stated objective: to encourage sorting of packaging, composting and recycling to reduce the weight and bulk of garbage bags, which will have to be kept at home for a little longer.

​Landes: compost from household waste soon to have no future?

Compost from the treatment of household waste may soon no longer be able to be sold to farmers as fertilizer, or spread, due to the plastic or glass residue it contains. A real source of concern for Sietom de Chalosse and Sictom du Marsan, which embarked on this development in the 1990s

This decision follows an experiment which proved conclusive, carried out in the Manot district, in Saint-Pierre-du-Mont, between November 2023 and January 2024. 508 households were divided into two sectors. In both, household waste collection was done every other week instead of every week. And in one of the two areas, the yellow bin was collected every week instead of once every two weeks.

Less garbage better sorted

The test proved that faced with a reduced collection frequency, with education, users sorted better and threw less textile waste, glass, or even packaging into household waste. “In household waste, we noted a drop per collection of 300 kilos collected in zone A, 370 kilos in zone B, or 12% less,” explains Laurent Dehez, responsible for collection and transport at Sictom du Marsan .


Household waste collected once every two weeks at Manot contained less waste which should have been sorted than in the waste collected in the urban area. But there are still some left.

At the end of the test, one in two residents wanted to maintain the collection once every two weeks. “We have not gone back and this will therefore be extended, during the first quarter of 2025, in agreement with the communities,” announces Christelle Chabasse, head of the communications and waste reduction department. “By extrapolating the results obtained for a neighborhood, the potential reduction in household waste is 500 tonnes less per year,” calculates Laurent Dehez.

“The potential for reducing household waste is 500 tonnes less per year throughout the city”

Professionals and residences, which have collective bins, will keep weekly tours, therefore separate from those of users. “We will do specific tours and we currently have to redesign the circuits. » Which makes the manager say that there are not necessarily savings made immediately on the transport item.

For the moment, there is no question of increasing the frequency of collection of sorted waste. “The differences in tonnage are not very significant, it is bulky waste that must be compressed, but not very heavy,” explains Laurent Dehez. No need to reverse the collection frequencies, at least for the moment. For those who have too much sorted waste, Sictom suggests increasing the size of the bin with the yellow lid. “But not to increase the black bin, the objective is to reduce the mass of household waste by reducing this waste,” explains Christelle Chabasse. Out of an average of 195 kilos of household waste per year per inhabitant of Manot, there are still 35 kilos of packaging to be collected from the black bin and placed in the yellow bin. »

Rural area and summer period

Continuing on, another incentive collection test began on 1is June and will last until August 31, in rural areas this time, throughout the commune of Garein. The situation is different there, since it involves collecting, every two weeks, 770 liter bins located at the collection points, where users and people passing through bring their bags.

Another data which varies compared to the first experiment: the test in Garein takes place during the summer period, and which says heat means more nuisance and constraints to store the bins at home. “We provide advice to reduce odors as much as possible,” Sictom representatives point out: close the black bags tightly, open the lid of the bin to ventilate it, place the bin in the shade and wash it regularly if possible. And finally, sort more and more, especially bio-waste. »

Concerns of collection agents

Last week, an extraordinary Territorial Social Committee (CST) was an opportunity for collection agents, “around fifty agents out of the 80 from Sictom du Marsan, to raise their concerns about the collection of household waste every two weeks, known as C0.5,” explains Jessica Lafargue, CFDT union representative in the body.
They expressed their fears about the weight of the bins and the nuisances to users from poorly kept trash cans for longer (odors, maggots). “The new collection rate is a decision of elected officials and the president. However, staff representatives understand concerns about arduousness. » In relation to weight, the first experiment at Manot gives hope that the quantity of household waste will decrease through better sorting of users. Then, solutions are being studied, “first with an exoskeleton, tested in recent weeks and whose implementation is hoped for at the end of 2024. Then by an investment in skips with a side collection arm for sometime in 2025 »
As for the nuisance, “we planned to go into the field, to go door to door in December and January,” explains Christelle Chabasse. There will be information, awareness raising and support for users. The entire communications and waste reduction team will take their pilgrim’s staff. » During the next CST sessions, “two collection agents will participate as experts”, announces Jessica Lafargue, to follow feedback from the field.
