Martin Thermal Engineering, Inc. has performed third-party reviews of air emissions and hazardous wastes generated at industrial facilities. In cases where air pollution equipment such as baghouses, electrostatic precipitators, scrubbers, catalysts, and fume incinerators are out of compliance and the vendor is no longer in business or is not helpful, an independent evaluation may resolve the problem or help resolve a claim. Similarly, evaluations of the characteristics of solid waste so that a determination may be made as to whether they should be categorized as hazardous (i.e., reactivity, ignitibility, etc.) can help resolve a dispute with environmental regulators.
