Described herein is a computing system for linking products and containers to cardholders. The computing system is configured to receive transaction data associated with a transaction carried out by a cardholder, the transaction data including an account identifier associated with the cardholder, a product identifier, and a container identifier associated with a product purchased in the transaction. The computing system also links the product identifier and the container identifier to the account identifier, and stores the linked product identifier, container identifier, and account identifier. The computing system receives, from a user device, the container identifier associated with the container received by a user associated with recycling the container, determines the account identifier linked to the container identifier associated with the product received by the user, and automatically provides a reward to the cardholder via the account identifier.
