TORONTO As more Canadians replace their old electronics with new technology, one Ontario-based company hopes its initiative will combat the country’s electronic waste problem, one smartphone at a time. Tony Perrotta, president and CEO of Greentec, says he sees his company as being a small part of the solution. “Part of the problem we’re dealing with in Canada is that e-waste is the fastest growing waste stream in Canada,” Perrotta told CTV News Channel on Saturday. According to the Canadian Wireless Telecommunications Association, which represents wireless companies and analyzes cellphone recycling patterns, two in three Canadians say they have a cellphone that they are not using. The organization says that the majority of Canadians also reported that they are aware that their mobile devices can be recycled.
