Paper is the most common type of waste in Singapore and about 1.26 million tonnes of paper waste was generated in 2008. The recycling rate of paper is 48% in 2008, 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.
And according to Friends of the Earth:
Paper recycling leads to savings in the use of raw materials for pulp and paper production and less wood is used. This should result in less intensive forest management and take the pressure off exploitation of old growth forests, vitally important for their biodiversity.
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.

5. Paper Recycling in Singapore
In Singapore, about 1.26 million tonnes of paper waste was generated in 2008 and the recycling rate is 48%. Paper waste is usually collected through the recycling programmes and traditionally by the karang guni men, waste paper collectors and traders.
The paper waste are sorted by type, baled or placed in containers, and exported overseas for recycling as there are no paper recycling mills in Singapore.
6. Collectors, Traders and Recycling Companies for Paper
To find a recycling collector or someone who wants your paper waste, you can use our online business waste exchange, Waste is not Waste. We connect businesses and organisations that generate waste materials with those who want the materials, thus helping both parties save time and money while helping the environment.
7. What Can I Do
You can recycle paper through the various recycling programmes at home, in school and your office, or through the public recycling bins in your neighbourhood. But before you do so, remember to minimise your paper waste by Reduce and Reuse.
