Disaster Waste Management inthe Pacific No incinerators, limited dumping site
 The most of the debris are green waste andgalvanized plates Shortage of materials for reconstruction

Segregation and reuse of disaster waste
are priority

Disaster Waste in the Small Islands
Tsunami(Earthquake)

Flood(Heavy Rain)

Cyclone(Strong Wind)

Mixed waste (destroyedhousing/building
Bulky waste, furniture, whiteware, car bodies, green
waste)

Contaminated mixed wastewith muddy water(destroyed housing,furniture, white ware, carbodies, trees, commercial
goods at stores）

Mixed waste (fallen trees,green waste, destroyedhousing)

Relatively clean and re-usable
if segregated on site (easierto recover materials)

Contaminated and not reusable and unsanitary(difficult to recovermaterials)

Relatively clean and reusable if segregated on site(easier to recover materials)

Most of the collapsed houses weremade by stone and mud mortar

Reconstruction of houses ispriority
 People segregate and collectstones and bricks for reuse But if they rebuild their houses
same as before, it will invite
another tragedy
 Though they reuse the materials,houses must be built stronger
 Nepali Government adopt “BuildBack Better “ as their basic
concept for reconstruction
