What is cullet?

Cullet is crushed glass that is used in the manufacturing of new glass products. It can be made from previously manufactured glass items, such as bottles or containers, and is often recycled to reduce energy consumption and raw material use in glass production. Incorporating cullet into the glass-making process helps improve efficiency and lowers emissions, making it an environmentally friendly option. Cullet can be categorized into different types, such as post-consumer or post-industrial, based on its source.
