Machines are currently sold on the secondary market, which means reuse already exists as a practical route. That creates a basis for more structured circular models around refurbishment, resale, maintenance and quality assurance.
For industrial food processors, the secondary market shows that equipment can retain value beyond a first owner. The next step is to professionalise that value retention: better data on condition, spare parts, hygiene requirements, performance and remaining lifetime can make reuse more reliable for buyers and sellers.
