Plastic Recycling

Plastic

In 2018, out of 949,300 tonnes of plastic waste generated in Singapore, only 4% (40 thousand tonnes) are recycled.
 
The global production and consumption of plastics have been on the rise, due to the increase in single-use plastics (disposable cups, utensils, straws, bags and most food packaging) that are thrown away immediately after use. 
Very often, plastics that reaches the bin are already contaminated, either by food and drink residues, or are made up of a mixture of different kinds of plastics. This greatly complicates and affects the recycling and segregation process. 
 
A plastic drink bottle for instance, is commonly made up of 3 types of plastics;
The bottle – PET
The heat shrink label – PVC
The bottle cap – HDPE 

Though PET bottles are easily recyclable when it is clean, the process of separating the labels (PVC) and bottle caps (HDPE) is often a difficult, costly, labour intensive and time consuming process, which is why m
ost of these plastics end up in the landfills instead of being recycled. 
 
  • Plastic Identification Codes does not mean that the plastic is recyclable, rather, it is developed to help categorize plastic products according to their material type.

Plastic Recycling Process

Plastic recycling process starts with sorting the different plastic types into their respective identification code. The different plastic products must be further sorted into coloured and non-coloured (clear/white). Clear plastics fetches the highest value, as it can be easily dyed into any other colour. Once the sorting is done, the plastics are washed and cleaned, so as to ensure that debris and contaminants are removed. It is then shredded, crushed into flakes, or melted and pelletized into granulates, which are used to manufacture new products.
