Paper is one of the most common types of waste in Singapore and 1.26 million tonnes of paper waste was generated in 2013. The recycling rate of paper is 54% in 2013, and most of this paper waste is sorted, baled and exported overseas for recycling as there are no paper recycling mills in Singapore.
Let’s take a closer look at paper recycling:
1. Types of Paper for Recycling
The different types of paper waste are collected and usually separated into the following categories for recycling.
- Corrugated cardboard
- White office paper
- Mixed paper
2. Why Recycle Paper
There are environmental benefits to paper recycling. According to Waste Online:
Producing recycled paper involves between 28 – 70% less energy consumption than virgin paper and uses less water. This is because most of the energy used in papermaking is the pulping needed to turn wood into paper.
Recycled paper produces fewer polluting emissions to air (95% of air pollution) and water. Recycled paper is not usually re-bleached and where it is, oxygen rather than chlorine is usually used. This reduces the amount of dioxins which are released into the environment as a by-product of the chlorine bleaching processes.
3. The Paper Recycling Process
At the paper recycling plant, sorted paper goes into a pulper where they are washed and screened to remove unwanted items like metals and plastics. The paper pulp then undergoes a floatation process to remove inks and adhesives. The resulting paper slurry is spread on wire meshes and drained of water using rollers to form sheets of paper.

4. Recycled Paper Products
Paper waste such as white office paper, corrugated cartons and newspapers can be recycled back to its original use. Magazines, mixed paper, newspapers and corrugated cartons are recycled as cardboards, toilet papers, paper towels, egg cartons, kraft paper, etc.
