WHAT IS THE SOLID WASTE MANAGEMENT?

Solid Waste Management is one of the major challenges faced by many countries around the globe ,inadequate collection ,recycling or treatment and uncontrolled disposal of waste in dumps can lead to severe hazards ,such as health risks and environmental pollution

USE OF PLASTIC WASTES• As a Plastic Roads• As a Plastic Roads

PLASTIC WASTE USED IN PROCESS : The following types of waste plastic can be used in the construction of the rural roads:• Films(carry bags and cups) thickness up to 60

micron(PE,PP,&PS)• Hard foams (PS) any thickness• soft foams (PS & PP) any thickness• Laminated plastics thickness up to 60 micron

(Aluminium coated also) packing materials used for biscuits ,chocolates,etc .,

• Poly Vinyl Chloride (PVC) sheets or Flux sheets should not be used in any case.

STEP 1 :-

Shredding machine – Cutting to required size Plastic waste- Cleaning process -Plastics waste (bags, cups, thermocole) made out of PE,PP and PS cut into a size between 2.36mm and 4.75mm using shredding machine ,(PVC waste should be eliminated).

STEP 2 :-

• Step 2(A)• Step 2(B)

STEP 2(A) :-

• Aggregate is transferred to chamber – Aggregate heated - The aggregates mix is heated upto a maximum of 165 degree celcious (as per the HRS specification) and transferred to mixing chamber.

STEP 2 (B) :-• Similarly the bitumen is to be heated upto a

maximum of 160 degree celcious (HRS specification) to have a good binding and to preovent weak bonding .(Monitoring the temperature is very important).

STEP 3 :-

• Coated aggregates waste plastics mixed with hot aggregate . At the mixing chamber ,the shredded plastics waste is to be added. It get coated uniformly over the aggregate within 30 – 60 seconds , giving an oily look.

STEP 4 :-

• Road Laying Process Aggregates – The plastic bitumen mix bitumen added. The plastic waste coated aggregate is mixed with got bitumen and the resulted mix is used for road construction . The road laying temperature is between 110 degree celcious to 120 degree celcious . The roller used is 8 -ton capacity .

OVERALL CHARACTERISTICS OF THE PROCESS :

• Easy process without any new machinery.• Simple process without any industry

involvement.• In situ process.• Use of lesser % of bitumen and thus savings

on bitumen resource.• Use of plastics waste for a safe and echo-

friendly process.

• Both Mini Hot Mix Plant and Central Mixing Plant can be used.

• Only aggregate is polymer coated and bitumen is not modified.

• Use of 60/70 and 80/90 bitumen is possible.• No evolution of any toxic gases like dioxin.• Fly ash can also be used to give a better

performance

Introduction to waste to energy plant(solapur plant)

REDUCE • You can help by PRECYCLING. 1/3 of all garbage is packaging. • Buy things that are in packages that can be recycled or are made of recycled materials. • When you buy something small, say no thanks to a bag.

REUSE

• Many things can be reused before you throw them out. • Use coffee cans and cottage cheese containers

for storage • Use backs of paper or backs of used envelopes

for jotting notes • Put leftovers in resalable containers instead of

using wraps and foil • Use old clothes as rags for cleaning instead of

paper towels • Have a garage sale or donate clothes, books or

toys that you don't use anymore

RECYCLE

• Each year we use: •25 billion plastic containers •100 billion pounds of paper •30 billion bottles & jars •65 billion aluminum cans
