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.

  • Newspapers
  • Corrugated cardboard
  • Magazines
  • 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.

5. Paper Recycling in Singapore

In Singapore, about 1.26 million tonnes of paper waste was generated in 2013 and the recycling rate is 54%. 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.

Construction and Demolition Waste Recycling

In Singapore, about 1.69 million tonnes of construction debris was generated in 2013 and the recycling rate is 99%. Construction and demolition (C&D) waste is usually sorted for the recovery of materials such as wood, metal, paper and plastics, and processed into aggregates for use in construction activities.

Let’s take a closer look at C&D waste recycling:

C&D Waste Recycling in Singapore

There are several recycling companies that collect and sort construction and demolition waste to recover useful materials from the waste such as ferrous metals, plastics, paper and wood. Sorting is done manually and by machines such as magnetic separators. The recovered materials are sent to local recycling companies for further processing. Some of the recovered wood can also be reused for construction activities.

The remaining waste after sorting contain materials such as concrete, bricks, gravel and stones, which are then crushed and screened to produce aggregates of different sizes for reuse in construction activities. These aggregates are also used to make recycled concrete products such as precast concrete blocks, drains and road kerbs.
