how companies combat waste

While the executive warned in case of rationing, companies will be the first to be affected, the latter multiplying initiatives to save gas and electricity.

Faced with the dangers of cuts and rationing this winter, the executive called on everyone to be strong, and in particular companies. “I call on each one (of companies) to establish, in September, its own resilience plan, launched Prime Minister Elizabeth Borne in her back-to-school speech.

If everyone does not do their part, (…) we will have to impose consumption reductions”, he warned. And “if we go to rationing, businesses will be the first to be affected”.

To do this, companies are multiplying initiatives to get rid of small and large waste. Overview of initiatives.

Agri-food

Fleury-Michon has built photovoltaic shade structures in the parking lots of all its factories. “This is the shade of the summer and will allow us to produce part of our electricity consumption,” said the group, saying that it has reduced the consumption of Kwh per kilogram of product by 30% in ten years.

Distribution

All the food brands – Carrefour, Intermarché, U system, Auchan, Casino and Leclerc – have switched off their illuminated signs from October 15 when the shops close, to reduce the light before arriving the public and lower the ambient temperature of the points of sale by one degree. These daily steps represent a 6% saving on the energy bill. Leclerc, in particular, started on September 12.

If it is very cold, if there is a high energy demand, extraordinary measures are proposed, such as lowering the temperature up to 17 degrees during opening hours, which allows a “reduction of 740 MW” or ” a” little. nuclear power plant”, promotes the technical distribution federation Perifem.

This protocol has been extended to other businesses. At the moment of not eating, the temperature of 17 degrees does not pass, because of the suitable rooms, but “if it is for two hours and to avoid a total blackout during a peak, it must who are able to think about themselves” , emphasizes Perifem.

Second major initiative, the installation of glass doors on the shelves of refrigerated products, which made it possible to reduce energy bills by 25%. The process is still ongoing: 70% of the distributors are equipped, but there are still 30% needed. The cost of installation – about one million euros for a medium-sized store – makes those who have not yet taken action hesitate.

Industry

The specter of gas cuts this winter is accelerating the race for solutions: heat recovery, switching to LED lighting or installing solar panels.

So the Toyota plant in Onnaing has two projects: the recovery of heat from the compressors in the surface heating treatment bath before the use of anti-corrosion in vehicles and the installation of solar panels in five hectares of parking lots. Such a measure makes it possible to achieve 10% energy savings, calculated Toyota.

The aluminum foundry of Saint-Jean Industrie (Belleville-en-Beaujolais) recovers the heat from its furnaces to heat the entire sector of the plant. Since the end of 2021, the group has obtained “between 10 and 15%” of electricity and gas, mainly by monitoring its consumption in real time.

Michelin, which has reduced energy consumption by 18% between 2010 and 2021, continues its efforts this winter. To save gas from its tire ovens, the group develops renewables and especially biomass boilers (in Cholet and Bourges), photovoltaics (in Puy-en-Velay) and buying biomass heat (in Vannes and Clermont-Ferrand).

In Troyes and Bassens, the group also buys heat, but from burning household waste. In addition, this winter, the heating temperature in offices and workshops “does not exceed 19 degrees”, and even drops to 17 degrees in workshops where “physical effort” is carried out.

The group also has an insulation plan for its tertiary sites, installing LEDs in workshops and outdoor lighting in its research center.

Veolia lowered the temperature of its premises and measured the consumption of each waste collection depot and each truck to identify corrective measures and deploy fuel-efficient driving training.

transportation

SNCF, a large consumer of electricity, has intensified its actions for several months by emphasizing “eco-driving”, a more flexible method of driving trains, for example by exploiting of the reliefs. This makes it possible to reduce energy consumption by up to 10% “without reducing (the) speed and therefore without penalizing travelers”, says the Ministry of Transport. the SNCF is also looking for waste in industrial and tertiary buildings, installing LED lamps on a large scale and playing with the lighting and heating of the stations.

However, the energy stability, of SNCF, RATP and other transport operators, “it is not a plan to make fewer trains, even this winter” assured the Minister of Transport Clément Beaune , which addresses rumors about removing trains to save energy.
