Booth #322

Hear NuTerra Director of Facilities Operations and the U.S. Composting Council President and Chair Lorrie Loder present “Aerated Static Pile System With A Biofilter Layer Show Promise Regarding Air Emission for Composting Greenwaste, Biosolids, and Foodwaste.”

Air emission assessment R&D programs have been conducted over the past few years using an innovative composting method. Pilot scale and full-scale studies have been conducted on positive aerated static pile with biofilter layer (+ASPwBFL) compost technology. This method utilizes a positively aerated static pile arrangement that includes a cover biofiltration layer composed of finished compost. Based on recent work on greenwaste composting completed by the San Joaquin Air Pollution Control District (Technical Advancement Program-TAP), this approach can reduce combustion emissions with the consequent reduction in indirect air emissions. In addition, based on the measurement data obtained, it is likely that direct emissions will be substantially reduced as well for full-scale operations.

This technology is appropriate for advective area sources found at compost facilities including windrow facilities, ASP facilities using a variety of composting strategies, and mechanical biofiltration pollution control strategies. A comprehensive technical approach using this assessment technology will be presented along with estimates of study compound fugitive air emissions along with a comparison of other compost emission data.

Only 30 seats available for public works managers interested in more economically and environmentally sustainable practices. Sign up now, so you don’t miss this opportunity to tour the wastewater treatment facility plant U.S. Naval Air Station Jacksonville (NASJAX) for a firsthand look at how NuTerra helped the base meet the U.S. Navy’s aggressive energy reform targets. Operating data confirms the installation of BCR Environmental’s CleanB® system has reduced annual energy consumption for biosolids treatment by 95% ($75,000) and greenhouse gas emissions by approximately 480 tons. The project was not only an environmental win, but also reduced overall operating costs by eliminating the need for aerobic digestion and is delivering the following additional benefits:

  • S. EPA-approved Class B biosolids beneficial reuse product suitable for land application
  • Total operating cost savings of approximately $105,000
  • Cumulative operating savings of approximately $2.9 million over 20 years compared with aerobic digestion operations
  • Payback on equipment projected at 5.0 years; 6.5 years including installation
  • Improved dewatering of biosolids eliminates 12 truckloads of biosolids, with an average annual savings in hauling and disposition costs greater than $10,000
  • 71% less polymer consumption

Bonus Tour Added: See how Clay County Utility Authority lowered its costs and risks of managing biosolids and organic waste with the BCR Neutralizer™ system that NuTerra installed. The system treats waste activated sludge and produces Class A residuals for unrestricted land application in just a matter of hours. Replacing its antiquated aerobic digestion process and the hauling of Class B residuals either to the landfill or land application sites with the Neutralizer system delivered:

  • 43% reduction in annual operating costs for biosolids treatment and disposition
  • 92% decrease in energy costs associated with biosolids treatment
  • Odor-free residuals
  • Enhanced nutrient removal that meets strict new standards for nutrient discharge
  • Adjustable pH to suit client needs, with an extremely low P index (phosphorous leachability)—0.1 Phosphorous Source Coefficient in a study performed by Penn State University
