Metal recycling in Singapore
Metal is one of the most recycled material in the world due to the ease of recycling. Metals can be recycled indefinitely without losing its properties.
In 2019, out of 1.278 million tonnes of ferrous metal wastes and 126 thousand tonnes of non-ferrous metal wastes generated in Singapore, 99% (1.270 million tonnes) of ferrous metal wastes and 99% (124 thousand tonnes) of non-ferrous metal wastes were recycled.
There are two main categories of metals, ferrous and non-ferrous. Although ferrous metals are recycled in greater volumes, non-ferrous metals are more valuable.
- Common non-ferrous metals (Non-Magnetic) are: Copper, Brass, Aluminium, Stainless Steel (304/316)
- Common ferrous metals (Magnetic, with Iron content) are: Iron, Stainless Steel (201)
