How to Recycle Window Glass

New glass is cheap to make, but that does not mean that used glass should sit in a landfill instead of being recycled. Recycling glass is good for the planet; however, not everyone knows how to recycle window glass. Not all local recycling centres can accept glass because it is thicker than other types of glass and made out of common materials such as lime and silica. Despite the fact that few centres accept window glass, there are a number of other options, including donating the windows to a nonprofit or other organisation, or crafting with them. These are just a few different ways to recycle glass.

Basics of Window Glass

There are many different types of glass, including sheet glass,tempered glass,laminated glass, and frosted glass, all of which manufacturers use for windows. There are various types of window glass, but it is different from bottle glass and other kinds of glass. Window glass is made of a variety of materials, including silica, sodium oxide, and lime. Window glass does come in different thicknesses, depending on the type of window. It is a good idea to know the type of glass because some recycling centres may have restrictions.

The thickness of the glass may affect what recycling centres are able to do with it, so consumers should make sure to check what type of glass they have.

Recycling Options

It is a good idea to know the different recycling options available. Not all consumers have access to a recycling centre that has the capacity to recycle window glass. However, if consumers do not have this option, many other organisations can reuse the materials.

Ways to Reuse Glass

Some organisations reuse glass from windows. Consumers should be able to find a directory of these organisations online. These organisations may include both salvage yards and green building companies. Some places accept donations while others may even pay individuals for the glass. One should contact these organisations directly to figure out how to drop off the materials and how much compensation there is if any.


Another option is to donate old windows to a nonprofit, such as Habitat for Humanity. Organisations such as this one use windows for building new houses. One can also donate these windows to a local theatre for use in a set. These organisations need whole windows or panes of glass though, so it does not work with broken pieces.

Recycling Centre

If the windows are not in good condition it is possible to just recycle the glass in some cases. However, it is not as easy as recycling glass bottles because window glass is much stronger. In some cases, window glass can actually damage equipment at a recycling centre. Additionally, often other materials such as aluminium and steel, are still attached to the glass. These materials are not recyclable, so the centre needs to remove them, which can be time intensive and expensive. Consumers who want to recycle window glass should start by finding out whether any place nearby can recycle it.


In addition to other recycling methods, consumers can also turn window glass into a variety of jewellery and other craft projects. Some projects that use window glass include glass art or jewellery. If consumers do not want to make art themselves, they may be able to donate the glass to local artists or a local art organisation.

Uses for Recycled Glass

Recycled glass has a variety of uses, including ceramic tiles, fibreglass, thermal insulation board, ceiling board, and paving blocks. Other uses for the glass include construction, and it can also be added to asphalt.
