Recycling system of concrete waste incurred from building demolition: Evaluation of recycling concrete waste using "life-cycle impact assessment method based on Endpoint modeling; LIME"

Abstract

A case study on various concrete recycling system in demolition of a thermal power plant was carried out from viewpoint of cost and environmental impact. In the study, one of the life cycle impact assessment method developed by Japanese national project "Life-cycle Impact assessment Method based on Endpoint modeling (LIME)" was introduced for the evaluation of effectiveness of the recycling system compared to only reusing for roadbed gravel and/or backfilling material. In this study CO2 emission, crude oil consumption, land use for waste disposal and use of natural aggregate are evaluated.
