Paper is by far the most common waste product, accounting for over 70% of all trash in businesses and educational institutions. Paper waste grows when it is not properly segregated. Therefore, it presents a challenge in global waste management that has led to increased landfill volume, paper waste that cannot be recycled, and deforestation due to the production of paper. While current solutions are helpful in mitigating paper waste, the researchers found out that there are limited studies that have integrated Internet of Things. The study aims to design, develop, test, and evaluate a reverse vending machine that exchanges used white paper for new white paper and serves as an alternative way to segregate paper waste using prototyping method. Test Results show that there is no significant difference in the response time of the sensors with p-value of 0.863 and there is no significant difference in terms of functional correctness of the system in dispensing the correct equivalent paper sizes (i.e., letter, legal, and A4) with p-value of 0.770. The results further imply that the system is consistent in terms of its time behavior and accuracy performance. The evaluation procedure yielded a "very good" rating in all criteria of ISO 25010:2011 standards in terms of functional suitability, performance efficiency, usability, reliability, and maintainability. This research project is aligned with the UN-SDG (Sustainable Development Goals) of ensuring sustainable consumption and production by addressing the consumption of paper waste.
