How is PET collected?

Collection schemes differ from country to country and from town to town. However the methods used are generally one of the following:
   
Kerbside collection: consumers separate bottles from their household waste putting them in special bags, then the bags are collected by the municipality;
Drop-off Locations: collection containers are placed in particular locations where the consumer can leave his bottles;
 Return Vending: generally placed in supermarkets, return vending machines allow consumers to return containers and receive coupons or tokens in return.
 Refill and Deposit: bottles are sold with refundable deposits redeemable on return of the bottle to the retailers'.
Once the bottles are collected, they are sent to the sorting line to separate the various streams of material.
