IN Brief:
- Clarebout says production capacity is around 14% to 20% above anticipated demand across its frozen-potato network.
- Mouscron 1 is the group’s smallest production site and operates older equipment with higher production costs per tonne.
- Up to 392 workers could be affected if consultation results in production being progressively stopped.
Clarebout Potatoes has begun consultation on the possible closure of production at its Mouscron 1 frozen-potato site in Belgium as the group tries to bring manufacturing capacity into line with weaker market demand.
The plant belongs to Mydibel SA, a Clarebout subsidiary, and remains part of the group’s industrial network while the Belgian information and consultation procedure runs. No final decision has been taken, but Clarebout says up to 392 workers could be affected if the proposal leads to production being progressively stopped.
The company has put unusually clear numbers around the capacity problem. Installed production capacity is currently around 14% to 20% above anticipated demand, leaving the business with fixed costs designed for higher volumes while competition and operating costs remain under pressure.
Mouscron 1 is the smallest production site in the Clarebout network and uses older equipment than the group’s other plants. Clarebout says that combination results in a higher production cost per tonne and lower operating efficiency, making the factory particularly exposed when the wider network is carrying more capacity than the market requires.
The consultation gives employee representatives an opportunity to examine the proposal, question its assumptions, and consider alternatives before management reaches a final decision. Production therefore continues under an unresolved process rather than an announced closure timetable.
The economics behind the proposal are familiar across capital-intensive frozen-food manufacturing. Potato processing carries substantial fixed costs through washing, cutting, cooking, freezing, packing, refrigeration, warehousing, maintenance, and utilities, so utilisation has a direct effect on the cost of every tonne leaving the plant.
When a network is materially oversized for expected demand, those costs are spread across fewer saleable tonnes. Producers can try to protect utilisation through pricing, export growth, product mix, or additional customers, but persistent surplus capacity eventually turns into a question of which assets are cheapest and most productive to keep running.
That comparison is particularly difficult where older equipment competes with newer lines. Modern processing plants can generally support higher throughput, tighter process control, greater automation, and lower specific energy or labour requirements, while ageing machinery may require more maintenance and operate with less flexibility around line speeds or product changes.
Clarebout has indicated that investment will continue at other sites in its network, focusing on operational efficiency, product quality, and future growth. The proposal therefore amounts to a reallocation of manufacturing capacity rather than a withdrawal from frozen potato production.
The group’s ownership has also changed during the past year. Clarebout became a subsidiary of J.R. Simplot Company in 2025, placing its Belgian and French operations inside a much larger international food and agriculture business. Clarebout and its subsidiaries employ around 3,000 people in Belgium and France and supply frozen potato products to customers in Europe and other markets.
Scale does not remove the need to rationalise plant economics. A larger industrial network creates more options for shifting volumes between factories, but every transfer has to preserve product specifications, packaging formats, quality systems, storage capacity, and delivery performance while the receiving sites absorb additional production.
Frozen products also carry a logistical penalty if manufacturing is moved without careful planning. Finished goods require controlled low-temperature storage and transport, so production allocation has to be considered alongside warehouse capacity, pallet flows, customer locations, and available cold-chain infrastructure rather than treating factory throughput in isolation.
The workforce consequences remain the most immediate element of the consultation. A potential impact on 392 roles is substantial for a single plant, while Clarebout must continue operating safely and consistently during a process that inevitably creates uncertainty around staffing and longer-term production plans.
The company has committed to continuing dialogue as the consultation progresses and says further information will be released as the process develops. Until then, Mouscron 1 remains operational and no definitive closure decision has been made.
The next significant figure will be the capacity left in the network if the proposal proceeds. Clarebout’s competitiveness will depend less on the headline number of factories it owns than on whether the remaining assets can operate at higher, more sustainable utilisation without simply shifting excess capacity elsewhere.
