COMPREHENSIVE EVALUATION OF THE ON-SITE PAPER CYCLE SYSTEM BASED ON SOCIAL RETURN ON INVESTMENT (SROI)

Abstract

 The sustainable Development Goals (SDGs) for 2030, adopted at the United Nations Summit, consist of 17 goals and 169 targets, and various proposals have been made to quantitative evaluate the degree of achievement. Social Return on Investment (SROI) is another example, calculated as the ratio of outcomes to inputs. The on-site recycled paper system using a dry office paper manufacturing machine, which was the subject of this evaluation, can make recycled paper on site by feeding unwanted paper into the machine, contributing to a significant reduction in water and transportation for the production of recycled paper. There is a movement to employ people with disabilities in the paper sorting and feeding stages, which is expected to contribute to the SDGs. In this study, we evaluated the SROI using actual data from companies that have installed dry office paper machines to comprehensively evaluate their on-site paper circulation system. As a result, the SROI value of this study was estimated to be 4.43. In other words, if the investment is 1, 4.43 times the social value is created.
