Waste Connections to Help Test Dual-Fuel System

February 15, 2011

CARLISLE, IA - GreenMan Technologies' American Power Group (APG) subsidiary has signed an EPA Test Vehicle Agreement with Waste Connections of Colorado to convert a refuse truck to APG's dual-fuel system and begin on-the-road test trials and emission-compliance approval. 

APG recently received an EPA exemption that allows public highway access for the testing and verification of APG's dual-fuel upgrade system on aftermarket diesel truck and tractor engines. APG's combustion engineers model each engine to determine the optimum mixture of diesel and natural gas. 

Waste Connections of Colorado is a wholly owned subsidiary of Waste Connections, which provides solid waste collection, transfer, disposal and recycling services in mostly secondary markets in the Western and Southern U.S. The company serves more than 2 million residential, commercial and industrial customers across 27 states. 

The test exemptions will allow APG to gather engine performance and emission data to support EPA approval requirements and begin commercialization of the dual-fuel upgrade system in the United States. The initial vehicle to be tested for Waste Connections of Colorado will be a 2007 11.5Liter /405 HP Mack refuse truck operating in the Denver metropolitan area.
