2. SUMMARY
▪ The recent earthquake has destroyed
thousands of houses and structures and
many need to be demolished and
reconstructed.
▪ Currently, due to the slow debris
management and lack of effective ideas for

4. ▪ The unmanaged
demolition debris in
the affected area
made me figure out
the possible
solutions to it.
▪ Initially, I started out
with dumping. But on
brainstorming found
it to be quite
ineffective.
▪ Tried applying
concept of 3R to the

processing industry in
Nepal was the main
challenge to make recycling

context
▪ So, We will be working with
the existing local
technology viz. Crushing,
wood processing and rod
manufacturing company
▪ This project will enhance
the existing local

6. DEBRIS END RECYCLED PRODUCT USES
Cement and Bricks Fine aggregate, Coarse aggregate
and Powder
• Structural and non structural
products
• Base layer of roads
• Coarse aggregates can be used to
make revetments
•Economical Retaining walls
• Mineral admixture to increase
durability and strength
Wood Wood Panels, Pallets, blocks and
Chips
• Wooden panels can be used in
furniture and structures
•Wooden chips can be used to make
chipboard and plywood
• Chips can be used as bedding
products
• Good source of fuel wood
• Soil remediation
Metal Billets and ingots can be further
processed into rod, sheet, wires etc
• Steel produced from the metal
scraps has variety of application
• Metal castings can be made
• Tubes and wire from extrusion of
billet have huge application
•Recycled sheets from rolling of
ingots can be used in construction
etc.

9. MPACTS OF THE PROJECT
✓ On local level Project Sadupayog will have
following impacts;
✓ The first direct impact of the project is
clearance of the debris
✓ Huge amount of employment opportunities
will be generated
✓ Most importantly, we will be obtaining raw
materials for the construction and
development
✓ Uplifting the existing industries and skills of
people i.e. Technological and skill

10. ▪ Socially, the project will be a common
platform to solve the society’s problem.
People will work together for a cause thus
promoting unity in the society.
✓ On Global level, this project will set an
example in the whole world and will draw
attention of investors and donors.
✓ The project is targeting the valley and other
urban and sub urban area
✓ The project will have long term impacts. This
will be an evergreen sustainable project as
construction and destruction is continuing
cyclic process. Even after the debris of the
