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.
Watch this animation video on the glass recycling process from RecycleBank:
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%.Â 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

7. What Can I Do
You can recycle glass bottles and containersÂ 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 would like to ask you where can i recycle my glass bottles because i have many glass bottles at home but don’t know what to do with it!
Hi Gwendolyn, you can recycle them at home through the National Recycling Programme (http://www.zerowastesg.com/2008/12/08/start-recycling-at-home/) or through the public recycling bins (http://www.zerowastesg.com/2009/02/13/where-can-i-find-recycling-bins/). If you really have too many, check with the glass collectors at http://app2.nea.gov.sg/topics_collectrade.aspx.

3. how do i put glass into recycle bag? shall i put them into a plastic bag before i put them into the recycle bag? tis point is not mentioned or pointed out anywhere, shan’t we put into a plastic bag 1st, so that wen the collectors collect & throw the bags, the glass inside wil smash but not mix with other materials, & also not to hurt the p’ple who sort the materials.

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?
Yes it is true – we have to pay for glass bottle recycling.
Why would any one do it? Because what we pay for glass bottle recycling may still be cheaper than throwing it away as rubbish at $76 per tonne.
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.
Do glass recycling companies/collectors require the bottles to be unbroken/unshattered when given to them?
Hi, can a tempered glass table top be recycled?
Dear everyone, I’ve recently started to grow hydrponic plants and have been using plastic food containers.If however, I may receive anyone’s kind contributions of glss jars or bottles or jars, I will be happy to have them cleaned andrefashioned into pretty recrafted or painted) jars for plants in hope of promoting both the aesthetic and health benefits of having indoor plants.
If anyone is willing to donate their glassbottles to me for recycling, please contact me at email@example.com so we may coordinate pickup according to your convenience.
Thanks much! cheers to zero waste and an even greener indoor Singapore!

What actually happens to glass that is given for recycling in Singapore ?? The incomplete info given above is from 2008/2013 and so may well be out of date, and there is no info available from a quick google search.
Does the govt pay for the glass to recycled in Johor ? NB that there doesn’t seem to be any free glass recycling available anywhere in Malaysia. According to one environmentally-aware resort on Pulau Sibu, they take the glass to Pasir Gudang and pay a factory there for recycling it.
Or does it go straight to the incinerator and then into landfill ?
So what actually happens to the glass that is put into the recycling bins here ??? Thanks for any insight into this, as there is only so much can be reduced or reused.
Hi I’m trying to find out what happens to glass recycling in Singapore ? It is very hard to find glass recycling in Malaysia, so not sure if that’s where it goes, and if government pays for that service ?? Or does it go straight to the incinerator ?
Does anyone know ? The information on here is very out of date.
