IN Brief:
- LIFE F3 has demonstrated technology for converting packaged former foodstuffs into feed ingredients.
- The project added more than 50,000 tonnes of annual processing capacity.
- Packaging separation, feed production, and commercial replication are converging in Europe’s circular food economy.
Trotec NV has expanded its circular feed model through the LIFE F3 project, using technology that converts unsellable packaged former foodstuffs into animal feed ingredients while separating packaging materials for recycling.
The LIFE-funded project has demonstrated industrial processes for recovering products originally made for human consumption but no longer suitable for sale. These streams can include packaged goods from food manufacturers, bakeries, cereal producers, confectionery plants, chocolate manufacturers, and retail supply chains. Instead of moving into disposal routes, the food fraction is processed into feed ingredients for livestock and pet food applications.
The technology has been implemented at Trotec plants in Veurne, Belgium, and Albon, France. A third factory is now under construction in Przasnysz, Poland, while commercial discussions are active in Spain. At Veurne, the process has also supported a new pet food product line now in pilot-scale production.
The project has expanded Trotec’s processing capacity by more than 50,000 tonnes per year. It has also freed up more than 9,000 hectares of agricultural land, reduced the carbon footprint of animal feed production, and cut dependence on imported raw materials. Packaging materials are separated by type during the process, directing aluminium, carton, paper, and plastic into recycling streams.
Sigrid Pauwelyn, Project Director and acting CEO of Trotec NV, said close-to-market support helped the company move from broad European demand into a structured ranking of expansion geographies. Poland and Spain emerged as priority markets, although with different levels of readiness.
The industrial difficulty lies in the packaged nature of the material. Former foodstuffs often retain significant nutritional value, but they may be wrapped, boxed, sealed, or packed in multiple materials that have to be removed reliably and safely. That creates a combined food processing, de-packaging, feed safety, recycling, and logistics challenge. If separation is slow, inconsistent, or contamination-prone, the circular route becomes difficult to scale commercially.
Trotec’s work connects several pressure points now shaping European food manufacturing. Waste reduction has moved into mainstream production economics as businesses work to cut disposal volumes, recover value from unavoidable surplus, and show credible handling routes for material outside saleable specification. Feed supply chains, meanwhile, remain exposed to imported raw materials, agricultural volatility, and land-use pressure.
The same direction is visible in the UK, where Tesco and RenEco have brought a Chelveston surplus-to-feed facility into live processing for packaged materials, manufacturing volumes, and store returns. Trotec’s European expansion points to a broader shift in which circular feed models are becoming process-engineered systems rather than simple waste diversion schemes.
The feed route is especially relevant because food manufacturing side streams are rarely uniform. A plant may generate off-spec baked goods, broken biscuits, cereal side streams, confectionery residues, discontinued products, overproduction, rejected packs, or returned stock. Each stream carries different moisture levels, energy value, packaging formats, contamination risks, and handling requirements. A circular feed system has to manage that variation while protecting feed safety and output consistency.
Commercial replication will depend on more than the core technology. Plants need reliable inbound volumes, clear contracts with food producers and retailers, feed safety controls, local permitting, packaging recycling outlets, and logistics routes that preserve the environmental benefit. Trotec has also examined adjacent routes such as pet food and insect feed, reflecting the need to match recovered materials with markets that can use them safely and profitably.
The possible move into ingredients for human consumption is a further signal of where side-stream processing may head, although that work sits outside the LIFE F3 project. Trotec is exploring whether certain former foodstuff streams can be converted into circular ingredients for human food applications through a separate company initiative in Belgium. That would involve more demanding technical and regulatory controls, but it shows how far material recovery thinking is moving from basic waste management.
Food manufacturers are under growing pressure to extract more value from existing raw materials. Ingredient inflation, agricultural stress, packaging regulation, carbon reporting, and disposal costs are pushing companies to look again at what leaves the plant. Former foodstuffs are structured materials with nutritional value, packaging complexity, and handling costs, not an undifferentiated waste stream.
LIFE F3 shows that the industrial answer depends on sorting, separation, feed formulation, quality control, packaging recovery, and market development working together. If the Polish factory and Spanish discussions lead to a wider European network, former foodstuff recovery could become a more standard part of food manufacturing resource planning.
