EC GPP Case Study - UNICA’s procurement of a food and beverage vending service with 64 machines in September 2019, through a concessions contract, resulted in four suppliers bidding for a five-year contract worth €210,000. This particular concessions contract is part of UNICA’s sustainability policy and aims to improve the services provided by the University in terms of environmental sustainability, through the reduced use of plastic and the promotion of circular waste management.
