This presentation discusses ways to reduce waste and promote recycling. It outlines the 7 R's for sustainable practices: reduce, reuse, recycle, respect, refuse, rethink, and repair. Various types of wastes like paper, plastic, metal, glass and food can be converted into useful products instead of dumping in landfills. For example, plastic bottles can be used to make houses, furniture and greenhouses. The presentation promotes greater public awareness about waste management and emphasizes that nothing should be considered waste before exploring potential for reuse.

• Wealth from waste is “GREEN
ENGINEERING”
• Green engineering is the process
and design of products that
conserve natural resources, and
impact the natural environment as
little as possible.

3. The 7 R’s
• Reduce: use less of something.
• Recycle: to re-use the item and create something
else with it.
• Reuse: to put into action or service again.
• Respect: treat with consideration
• Refuse: to avoid buying products that are not
sustainable or recyclable
• Rethink: to think about how you can reuse a product or
its materials
• Repair: to repair products rather than buy new ones.

4. Quantity of Waste contribution
• The average person throws away 726
kilograms of waste each year
• The average family throw away the
amount equal to 1 . 5 TONS of rubbish
each year

6. General items found in solid waste:

7. Composition of different kinds of wastes in waste stream:

7,000 gallons of water
380 gallons of oil

space(Paper takes up as

space)

shirt out of only five recycled plastic soda
bottles.

energy as burning it in an incinerator
• Recycling one ton of plastic saves 7.4
cubic yards of landfill space.

46. 1. “Compressed wood” is that which has been impregnated with
resin and subjected to a high pressure to increase its density and
strength. (this is stronger than normal ply wood).
2. “Particle board” also known as particleboard and chipboard, is an
engineered wood product manufactured from wood chips,
sawmill shavings, or even saw dust, and a synthetic resin or other
suitable binder,which is pressed and extruded. Large pieces of
whole wood are mulched and then washed, and a solution that is
basically glue based is added back into the pulp and then it is
dried and "compressed" into panel shapes for use called as
“particle board ”
3. A form of wood fuel, wood pellets are generally made from
compacted sawdust or other wastes are used as heating fuels
called as “fuel pellets”

47. Hazardous wastes
