While some look at a junkyard and see heaps of plastic, broken materials and tattered cloth, the researchers behind the “Waste Not, Want Not” project see an opportunity. Aiming to mitigate the environmental impact of scrapped resources, the research team spent the last summer and fall repurposing waste into functional items. They unveiled their projects from the last six months to the public Monday at Campbell Corner Gallery and held a gallery talk Friday to showcase their progress towards a more sustainable man-made environment.
