Cullet
Cullet is the industry term for recycled, crushed glass that is used to make new glass products. Think of it like chopped-up pieces of old glass bottles, windows, or other glass items that have been cleaned and processed to be used again. Using cullet is important in glass manufacturing because it helps save energy, reduces waste in landfills, and makes the glass-making process more environmentally friendly. When someone mentions cullet in their resume, they're typically talking about working with recycled glass materials in either a recycling facility or glass manufacturing plant.
