Prior works have suggested various strategies to increase construction
waste recycling (CWR) rates. However, choosing the strategies is
challenging without a lateral comparison. Therefore, this study aims to
compare the usability of various strategies that target the enhancement
of CWR implementation. To achieve this purpose, thirteen CWR enhancement
strategies were identified from a systematic literature review. Then,
questionnaire survey data were collected from 106 construction project
managers. The collected data were analyzed via mean score ranking,
normalization, overlap analysis, agreement analysis, and factor
analysis. Additionally, the data were analyzed using a proposed formula
for computing usability indexes using the cost, easiness, and
effectiveness values. The results show that three strategies have high
usability indexes: organize temporary bins in each construction zone,
identify construction activities that produce recyclable materials, and
enhance company policies related to CWR. These strategies with high
usability indexes are consistent with the overlapping cheap, effective,
and easy strategies. This study provides researchers and practitioners
with optimal strategies for enhancing CWR implementation. Effective CWR
enhancement strategies can improve CWR rates in construction projects.
Future researchers can also adopt this study’s approach in computing
usability indexes through questionnaire surveys.
