UNSW produces various waste streams including paper, cardboard, e-waste, batteries, mobile phones, printer cartridges, fluorescent lights, food waste, green waste, and hazardous waste from research activities. UNSW has programs in place to collect these waste streams for recycling or safe disposal. Paper, cardboard, batteries, mobile phones, printer cartridges, and fluorescent lights can be recycled through bins located across campus. Food waste is converted to compost and cooking oil is converted to biodiesel. Construction and demolition waste is managed through on-site separation requirements. Hazardous waste from research is disposed of by specialist contractors.
