Professor Castaldi has been interviewed on some of the thermal conversion aspects related to waste film plastic. EEC has done some research in the past related to non-recycled plastic waste and recently focused on film plastic (i.e. wrapping, flexible contaniers, etc) demonstrating that thermal conversion processes are likely the best technology for treating that stream thus diverting from landfills. For example, The range for the lower heating value for plastic waste was experimentally determined by EEC|CCNY to be between 22.9 and 41.0 MJ/kg (19.7-35.3 MMBtu/ton). Evan after long term exposure the original heating value was reduced by less than 5% making thermal conversion technologies well-positioned to recover the inherent energy and residual metals.
