The
purpose of recycling is to reduce waste at source and reuse it. MRF is the
first step in the recycling process and also plays an important role. To sort
and prepare recyclable materials for alternative use.
There
are four main types of MRFs, each of which depends on the source material
streams:
Source
separated - The incoming recyclables are already sorted at the collection
point, so only simple processing is required. Its main purpose is to remove
residual contaminants and prepare raw materials for the market.
Double
stream - Recycled material is received in two streams, usually fiber
(newspaper, magazine, mixed paper, cardboard). The separation of materials is
accomplished by a combination of automatic equipment and manual sorting.
Single
stream - Recycled material is received in a single stream, and combines the
fibers and mixing containers. The first stage of processing usually uses
equipment to separate the material into two streams (fibers and containers). A
device similar to the dual-stream MRF was used for further sorting.
Mixed
Waste - MSW is the use of different technologies to separate mixed recyclable
materials from the waste stream. The recyclable material is then processed
using a device similar to the single-stream MRF. Some facilities deal with the
entire waste stream, while others target commercial waste or load large volumes
of recyclables.
