The class has taken household items, which can't be decomposed easily in landfill, covered them in toilet paper and then painted them bright colours.
The artistic display - titled Residual Objects - contained gumboots, a telephone, radio, lamps, computer keyboard, hair drier and drill, and was set up in the teenage section of the Dunedin Public Library this week to highlight the amount of unrecyclable material sitting around the average Dunedin household, art pupil Laura Carruthers said.
"We wanted to turn something that can't be recycled into something useful."
Art pupil Shannon Morton said the display also marked the first anniversary of Columba College becoming an Enviroschool, an initiative which was growing in New Zealand schools.
