It depends on a number of factors -- size of your collection bin, purchase of indoor bins, frequency of pick up, how many other businesses in your area are composting, and your contract with the compost hauler.
As an example, Jewel grocery stores have successfully implemented food scrap composting at 169 of their stores in Illinois. There are only six company stores in the state that do not have access to this service at a reasonable cost. The program has been cost-neutral overall. Due to infrastructure, there are some variances in price from store to store for the service. The company does find value in this program and significantly reduces their volume of waste sent to landfill. Initial training was done in-house by the Environmental Sustainability Manager and has since transitioned to the managers in each unit to continue ongoing training efforts.
Depending on the makeup of your specific food service location, there may be opportunities to take advantage of current compost pickup routes or work with other businesses to share the cost of collection. This provides efficiency for haulers (referred to as “route density”) and cost savings for food scrap generators (such as restaurants).
