Scientific & Academic Publishing, 2020

Abstract

Food waste is considered by many people as non-useful materials. Global food wastage is approximately one third of the food produced in the world for human consumption every year. The total food wastage by consumers in industrialized countries is almost equal to the entire food production in sub-Saharan Africa. Food wastage creates environmental pollution problems in addition to the waste of resources. Many people are of little concern about the food wastes they consume because they have no clear awareness about the individually accumulated wastage over a period. At present there is no system to provide information on individual food waste and to make people aware of the magnitude of impact they create on the environment as well as incurring of high cost by obtaining unwanted amounts of food and then discarding. This study, therefore, aimed to design a system in view of reducing food wastes in organizations where food is supplied to the employees during working period. Philosophy behind the study is to make the people aware of their individual food wastes just after consumption and cumulative wastes, by providing information through a smart bin, thus encouraging the people to self-judge on how much they contribute to the problem and make necessary adjustments in obtaining the food from counter. A smart waste bin was designed and assembled with necessary controls to identify the user and measure the individual food wastes, and to calculate cumulative waste done each worker over a period.
