The functional economy focuses on the use of a product rather than its ownership. Specifically, with the functional economy model, a company sells the right to use a product of which it maintains ownership. The famous example is Michelin, which no longer sells tires for fleets of company cars, but supplies "mobility services" consisting of repairing, retreading and in some cases exchanging tires. The economic outcome is that the company has an interest in making its products last as long as possible because the price is based on usage (in this case, the number of kilometres driven) and thus in reducing waste.
