What is a glass crusher, how does it work, and can broken glass be recycled in Australia?

A glass crusher is a machine used in Australia to break glass bottles and jars into small, manageable pieces called cullet for easier recycling and disposal. It helps reduce glass volume by up to 80%, making waste storage, transport, and recycling much more efficient.
It works by feeding glass into a hopper where internal steel hammers or rotating blades crush it into small fragments. The crushed glass is collected in a bin and can then be sent for recycling or reused in construction materials.

In Australia, most broken glass can still be recycled, but it must usually be free from contamination like ceramics, mirrors, or treated glass. Standard bottles and jars are accepted in recycling systems, where they are cleaned, crushed, and melted into new products.
So yes—glass is fully recyclable in Australia, and glass crushers simply make the process faster, safer, and more cost-effective for businesses.
