    Material Recycling Sorting Facility Design and Process

    The materials recycling facility is the first place where all recyclable materials collected by kerbside collection services are taken. These co-mingled recyclable materials are then sorted into different material types and baled for sale purposes. A number of manual and mechanical sorting processes are used to remove all waste material before sorting into different categories.

    A recycling material sorting machine design needs to take into consideration the different stages of the recycling process for optimal effectiveness.

    The process of automatic recycling sorter usually includes the following steps:

    1. Transportation

    Collection and transportation of recyclable materials to an MRF facility using kerbside collection services and recyclable collection trucks. The materials are delivered to a receival bay or pit where they are transported via a conveyer belt through a paddle or metering drum machine that helps regulate the flow of the material to the pre-sort stage.

    2. Pre-Sort

    During the pre-sort stage plastic bags, cardboard, general waste, steel, large plastic items and other contaminants are removed manually. The remaining materials continue on the conveyer belt to the next stage.

    3. Star Screen Sorting Stage

    A star shaped shaft designed to further separate light materials like cardboard and paper from heavier materials such as glass, aluminium, steel and plastic is used in this stage.

    4. Steel Removal

    A series of overhead, rotating, powerful magnets remove ferrous metals and drop them into a cage.

    5. Aluminum Removal

    An electromagnetic field known as an Eddy Current repels aluminum and the material automatically drops into a cage below.

    6. Optical Sorting

    Optical sorting technology is used to further separate plastic types into two categories: 1 & 2 (PET & HDPE); and 3-7, using air jets and infrared sensors.

    7. Manual Sorting

    Any plastic materials remaining are sorted manually and transported to storage bunkers.

    8. Baling

    All separated materials are compressed into separate bales which makes it easier to weigh and transport.

    9. Final Transportation

    Baled materials are transported to different processing facilities for further screening and turned into recycled packaging or other products for purchase. Buying recycled products helps to complete the recycle loop.

    Manufacturers of material recycling sorting facility also design and build customized buildings to house recycling and sorting equipment. A technical team can provide customers with a design layout to optimize production and profits. They will assist in maximizing available space and help to ensure that the materials recovery facility and recycling and sorting equipment are both efficient and safe to run.

    Different Types of Material Recycling Sorting Facility Design

    There are a wide variety of generation points in a waste management system including: commercial sectors, single-family dwellings; and multi-family dwellings. There are 8 types of MRFs in a waste management system:

    1. Mixed waste MRF including the processing of MSW;

    2. Pre-sorted recyclable MRF – presorted by residents or curbside sorting by a collection crew;

    3. Co-mingled recyclables

    4. Co-collection in which mixed waste and co-mingled recyclables are separated into two colored bags separating waste from recyclables and collected in a single truck.

    5. Co-collection in which materials are collected by a three compartment truck, one for mixed waste, one for paper and one for non-paper recyclables.

    6. Front-end MRF for a composting facility which is similar to mixed waste but includes additional provisions for sorting and removing contaminants that may affect the composting process.

    7. Front-end MRF for an anaerobic digestion operations facility that includes additional removal of contaminants that may adversely affect the quality of digestive solids, or the digestive process.

    8. Front-end MRF for an RDF (refuse derived fuel) facility including material recovery operations.
