This thesis proposes the conceptual development of a sustainable system for ordering food boxes for meal preparation via mobile applications. Meal prep box delivery services have become increasingly popular over the past few years, especially among people who want a convenient and healthy solution to eating well without spending too much time cooking and preparing meals. This concept offers users numerous benefits. Pre-portioned groceries are delivered to the user's doorstep so that he does not need to make constant trips to the store. For numerous users, this type of service provides an adapted type of diet specific to their wishes and needs. When examining the eating and shopping habits of Croatian users of similar mobile applications, it will be determined whether there is a demand for this type of service. Based on the obtained results, the target group of this service will be determined and a sustainable visual solution for the grocery box and mobile application will be designed through which the specified product (grocery box) will be able to be ordered. A sustainable visual solution includes the use of environmentally friendly packaging materials and an aesthetically appealing and unique design concept that is suitable for recycling and mobile application prototypes. The proposed visual solution aims to solve the problem of food and packaging waste in nature so that users present a new sustainable product that is not yet on the Croatian market. More detailed research and testing is needed to confirm the feasibility and effectiveness of the proposed sustainable product.
