The Rebuilding Exchange is a Chicago social enterprise and non-profit that promotes reuse by diverting building materials from landfill and selling them affordably to the public. Its warehouse is filled with salvaged doors, fixtures, timber, furniture and architectural pieces, and it runs job-training and education programmes in sustainable building. Shopping or donating here supports the circular economy and workforce development, making it a rewarding and responsible destination for bargain hunters, renovators and anyone who cares about sustainability in the city.
