Building demolition waste represents a huge environmental challenge worldwide. The environmental implications are not only associated with volume, but also with carbon embodied in the waste. These adverse environmental impacts associated with the generated waste can be minimised through appropriate waste treatment strategies. This chapter evaluates the various stages of the life cycle of demolished waste materials, the potential carbon emission reduction associated with different demolished wastes and waste treatment strategy options. An assessment framework was developed and exemplified by a case study of a supermarket building. The results showed that the processing or treatment stage generate the largest amount of carbon emission (81%) in the life cycle of demolished waste materials, whilst the transportation stage contributed the least (1%). It was further found that steel waste recycling has the greatest environmental benefits (more than 90%) compared to concrete (less than 1%). Additionally, the study revealed that landfilling waste generated the largest
amount of carbon emissions compared to recycling. The findings can contribute to mitigating the environmental building demolition projects. Furthermore, the detailed assessment approach provides theoretical and methodological guidance which can be adopted to guide the quantitative analysis of other types of demolition projects globally.
