Glass Recycling

December 8, 2008 by

In Singapore, 73,500 tonnes of glass waste was generated in 2013 and the recycling rate is 20%. Glass waste is usually sorted and exported overseas for recycling as there are no glass recycling plants in Singapore.

Let’s take a closer look at glass recycling:

1. Types of Glass for Recycling

Glass bottles, jars, containers and glass sheets are collected and sorted into the different colours for recycling: Clear, Brown and Green.

2. Why Recycle Glass

There are environmental benefits to glass recycling. According to Waste Online:

If recycled glass is used to make new bottles and jars, the energy needed in the furnace is greatly reduced. After accounting for the transport and processing needed, 315kg of CO2 is saved per tonne of glass melted.

For every tonne of recycled glass used, 1.2 tonnes of raw materials are preserved.

Recycling reduces the amount of waste glass which needs to be landfilled. Although glass is inert and is not directly hazardous to the environment, it will remain there indefinitely.

3. The Glass Recycling Process

At the glass recycling plant, glass waste is sorted into different colours and crushed into small pieces called cullets. Contaminants such as paper and metal are removed, and the cullet is melted in a high temperature furnance. The molten cullet is then molded to form glass products.

4. Recycled Glass Products

Glass waste can be recycled continuously and made into new glass products like bottles, jars, containers and ornaments. The glass cullet can also be crushed into powder and used as material in making bricks, tiles, abrasives and replacement of sand.

Watch this video on how abrasives are made from recycled glass cullet powder:

5. Glass Recycling in Singapore

In Singapore, 73,500 tonnes of glass waste was generated in 2013 and the recycling rate is 20%. Glass waste is usually collected through the recycling programmes. The glass waste is sorted and exported overseas for recycling as there are no glass recycling plants in Singapore.

It is also common for beer bottles to be collected from restaurants, hotels and food outlets for reuse in a local brewery (not included in the recycling figures).

6. Collectors, Traders and Recycling Companies for Glass

To find a recycling collector or someone who wants your glass waste, check out NEA’s list of collectors and traders.

For companies, you can use the online business waste exchange, Waste is not Waste, to find someone who wants your waste.

7. What Can I Do

You can recycle glass bottles and containers through the various recycling programmes at home, in school and your office, or through the public recycling bins. But before you do so, remember to Reduce and Reuse your glass waste.

    I’ve been collecting glass bottles from my cafe for a couple of months and brought it to a recycling company in Kranji to sell. To my surprise they not only didn’t want to pay me anything but they wanted to charge me for “disposal”! Is that possible? I spoke to the manager who told me that it is because they don’t do the actual recycling in Singapore and that it needs to be sent to Malaysia. It doesn’t make sense to me. How is that different from recycling paper or metal? Why would anyone bother transporting waste glass to a collection facility instead of dumping it together with regular refuse?

    I feel that if supplier can collect back the bottles eg bird nest,chicken essence bottles, They are thick, won’t break easily, just rinse, put it back into the box and pass to the shop, like before, they use to collect drink bottles back.
