includes taking any type of plastic, sorting it into
different polymers and then chipping it and then melting
it down into pellets. After this stage, it can then be
used to make items of any sort such as plastic chairs
and tables. Soft Plastics are also recycled such as
polyethylene film and bags.

Methods for plastic wastes collection
Methods for Plastic Wastes
Collection

Management
Plastic consumption has grown at a tremendous rate over
the past two decades as plastics now play an important
role in all aspects of modern lifestyle. Collection and
disposal of plastic waste has emerged as an important
environmental challenge and its recycling is facing
roadblocks due to their non-degradable nature. There are
four basic ways in which communities can offer plastic
recycling collection services for plastic bottles and
containers – curbside, drop-off, buy-back or
deposit/refund programs.
Curbside Recycling
The first, and most widely accessible, collection method
is curbside collection of recyclables. Curbside (or
kerbside) collection is considered a low-risk strategy
to reduce waste volumes and increase recycling rates.
Materials are usually collected in large bins, colored
bags or small open plastic tubs specifically designed
for content.
Curbside recycling programs are generally the most
convenient for community residents to participate in and
yield high recovery rates as a result. Communities that
provide curbside collection generally request residents
to separate designated recyclables from their household
garbage and to place them into special receptacles or
bags, which are then set out at the curb for collection
by municipal or municipally-contracted crews.
Drop-Off Recycling
In this method, containers for designated recyclable
materials are placed at central collection locations
throughout the community, such as parking lots, mosques,
schools, malls or other civic associations. The
containers are generally marked as to which recyclable
material should be placed in them. Residents are
requested to deliver their recyclables to the drop-off
location, where recyclables are separated by material
type into their respective collection containers.
Drop-off recycling programs are more suitable when
residents are taking their garbage to a central waste
collection facility or transfer station. Such programs
suffer from low or unpredictable throughput.
Buy-Back Centers
Most buy-back recycling centers are operated by private
companies and pay consumers for recyclable materials
that are brought to them. Buy-back centers usually have
purchasing specifications that require consumers to
source separate recyclable materials brought for sale.
These purchase specifications can greatly reduce
contamination levels and allow the buy-back center to
immediately begin processing the recyclables they
purchase, while providing consumers with an economic
incentive to comply with the specifications. Buy-back
centers are similar to drop-off centers expect they pay
waste generators for their items based on market values.
Deposit/Refund Programs
These programs requires collection of a monetary deposit
purchase of a plastic container. When container is
returned to an authorized redemption center, or to the
original seller, the deposit is partly or fully refunded
to the redeemer. These programs are familiar to anyone
in the USA who has ever purchased a beverage in a can or
bottle. |
