ENHANCED ABSORBERS WITH BIODEGRADATION

Since the early 1970s, air pollution control regulations have required many businesses to install emission control systems to destroy volatile organic compounds (VOCs) and/or hazardous air pollutants (HAPs), or face fines. Some of the significant changes that influence the selection of solutions for reducing emissions of VOCs and HAPs are:

  • The implementation of the Maximum Achievable Control Technology (MACT) provisions of the Clean Air Act. Many of the facilities affected by MACT standards consider the reporting and control of HAP emissions to be the single largest driver toward VOC abatement
  • Increased public interest in the environment through web-based access to right-to-know reports. This continues to prompt many companies to find innovative ways to reduce pollution;
  • The emergence of regional air-quality initiatives related to ozone transport and market-based incentive programs such as emission-reduction credit trading programs;
  • Highly political or newsworthy issues in air quality management, such as the recent legal battle over EPA’s ambient air-quality standard for ozone, the public dialogue over smog and urban sprawl, and the efforts to balance the regulation of stationary and mobile sources;
  • The refocusing of environmental policy from a command-and-control format to a more collaborative, incentive-based approach that promotes pollution prevention
    over end-of-pipe control; and
  • The emergence of international agreements to enhance regional environmental cooperation, avoid potential environmental and trade disputes, promote effectiveenforcement of environmental laws, and explore transboundary air issues.
