Abstract/Summary

Waste sorting has been a lasting problem in DLSU. Concerned departments such as CSO and BGMO has taken initiatives in order to improve the waste separation in the university. Despite this, large amounts of trash still remained unsegregated. Through naturalistic observation and needs analysis, it was found that there was a 62.29% error in the waste separation behavior caused by (1) difficulties in using the waste bin, (2) a lack of knowledge in waste sorting, (3) inconvenience when sorting, and (4) confusion brought about by mixed waste. The general objective of this study is to improve the waste bin set by modifying its label & form to improve waste separation performance of the DLSU community. Decision of BGMO and CSO established an initial target of cutting the current waste sorting mistakes in half, and an ideal goal of I 0%. Addressing the four significant causes of waste sorting error is the sub-objective of this study. Concept and theories behind the design were studied through the review of related literature. HOQl was used to specifically identify the user needs, and the corresponding technical requirements of the attributes of the waste bin that needs to be improved. Designs would be generated through the use ofHOQ2, Concept Selection Matrix, and Detailed Design Process. From this, the first concept of the design of the waste bin was formed. Succeeding designs from the iterations were made through analysis and on-site interviews of the users from the naturalistic observation in prototype testing. Appropriate adjustments were applied until the target percent error in waste sorting was achieved. Testing demonstrated that the users' difficulties were addressed. Prototype testing of design 3 resulted to a sorting mistake of only 14.29% which is better than the initial aim of at most 50%. Therefore, the objective of the study was achieved.
