Why recycle PET?
PET is one of the most widely used plastics, but PET cannot be decomposed, causing serious environmental pollution. Therefore, in recent years, many governments around the world require public entities and businesses to use recycled PET products, and major international brands have also set targets for using recycled materials. These measures have promoted the development of PET recycling technology.
PET (Polyethylene Terephthalate, polyethylene terephthalate) is one of the most common plastics for hard packaging materials for beverages and food, and one of the most widely recycled plastics. Europe is the most common area to use environmentally friendly recycled PET. According to Eunomia, the EU’s PET demand in 2018 was 5.3 million tons, of which 1.4 million tons came from recycled PET (rPET).
Currently, less than 60% of bottled PET is recycled and reused, and only 6% of it can be recycled into bottles. There is still a large market for recycled PET bottles.
How to recycle PET?
Today’s PET recycling can be roughly divided into two types: physical PET recycling and chemical PET recycling. Physical PET recycling
PET physical recycling technology has long been commercialized, and physical recycling technology has been continuously improving. Basically, the general process of recycling PET or PET bottles is: the first step is to use an unpacking machine to unpack the bottle bricks, separate the label and the bottle body, perform manual and automatic classification, then wash with lye, and then pre-wash The bottle is crushed into bottle flakes with a crusher. The PET bottle flakes can be ground into PET powder with a pulverizer, which is used as the raw material for injection molding and extruder. The other is PET bottle flake recycling and granulation to obtain new PET particles.
Chemical PET recycling
In recent years, the complexity of commercially available PET packaging materials and the widespread use of PET have led to increasingly complex recycling operations. In addition, polyester fibers made of PET cannot be recycled with the current physical recycling technology, so they will be used after use. The chemical recycling method of recycling PET or polyester fiber clothing into monomer is necessary.
The main chemical recovery methods in the industry can be divided into various chemical recovery methods such as Glycolysis, Methanolysis, Hydrolysis, Bioenzyme decomposition, and other methods.
