Natural disasters can generate large quantities of waste that may directly threaten public health (e.g. direct human contact with hazardous waste such as asbestos), impede reconstruction (e.g. block access to affected populations and areas) and impact the environment. In particular, damage to infrastructure and buildings generate a significant amount of Construction Waste such as bricks, concrete and concrete rubble. This occurs in two phases: (1) when the actual natural disaster occurs and (2) later during the response and recovery activities (Figure 1).
