The Situation ..
People sincerely wish to process whatever plastic they have, in an environment friendly way, however, not finding an easy clue to do it easily. And this is an opportunity if you can see as an entrepreneur.Plastic Processing method at present
In India, the house hold waste is collected from houses by the municipal employees. We are instructed to separate the DRY vs WET. That's all. After this, the municipality separates the same at centres. Here, the Bio degradable & non bio degradable is sorted out. In the non bio degradable category, comes the plastic. In plastic too, there are several types by which they are separated, just have a look at these :-
From the municipal waste, appx 12% is Plastic waste. Out of this plastic waste , around 64% waste is generated from thin carry bags (thus it's the top priority). 9% from PET bottles & 23% from the remaining types. From the 9% again, they say (like Bisleri) that around 90% is already recycled (See what measures Bisleri takes to recycle the PET)
How the Waste gets processed ...
The PET Bottles : For creating yarn from it & apparels, clothes ultimately. See this blogpost
All Plastics : Road Construction, Incineration at Cement Kilns, Waste to Fuel, Granules creation can be the other ways. Creative ways like Making Paver Blocks have also emerged. You can see the Plastic Waste Management rules for details on this, setup by the Govt.
Note : Industries have a different procedure for this. However the procession remains the same.
