DENVER --- Every second, the equivalent of one dump truck filled with clothing and other textiles from around the world is sent to a landfill or incinerator. Perhaps even more upsetting, many of the clothes were never even worn. Clothing companies commonly destroy, incinerate or send to the landfill unsold and unused clothing, known as overstock, to make way for new merchandise. To address the huge amount of clothing that is wasted and turned into environmental pollution each year, U.S. PIRG and state PIRGs launched a campaign on Tuesday calling on states to hold the industry accountable for its overproduction and ban the destruction of overstock.
