ABSTRACT
Conventional waste management systems and tools used in construction are often effective up to a point. They are effective for tangible or material wastes – the stuff that ends up in skips and bins. They are not too useful when we wanted to deal with the Eight Wastes from the Hidden Construction Site. This is probably because conventional waste management often comes from environmental management instead of business management (see Figure 9.1). Therefore they are good for ‘end-of-pipe’ solution when the physical waste is already generated. The focus on reuse and recycle is very good for timber or sheet metal, but fairly useless for waiting or lost talent and ideas. This means the Waste Hierarchy can be further divided into all wastes and tangible wastes.
