The Pennsylvania Department of Environmental Protection will hold a public meeting on Oct. 30 to discuss the air quality permit application submitted by Delta Thermo Energy Inc. to construct a waste-to-energy plant in Allentown in Lehigh County.
“This is an opportunity for DEP and Delta Thermo to answer questions from people in our community,” DEP Northeast Regional Director Mike Bedrin said. “There has been significant public interest in the proposed facility and we look forward to providing more information to the public.”
The company is proposing to build a generating facility that will use municipal solid waste and sludge from the city of Allentown’s wastewater treatment plant as fuel to generate 4 MW for internal use and sale. The facility will be capable of processing 120-tons-per-day of municipal solid waste and 47-tons-per-day of sewage sludge.
In a Sept. 14 public notice, the DEP had given the project company name as Delta Thermo Energy A LLC. A March air permit application uses both versions of the company name.
The company’s website says: “Hydrothermal decomposition is DTE’s key technology. It combines high pressure and high temperature water steam to break down municipal solid waste (MSW) or sewage waste (biosolids) into a clean pulverized material with a high caloric content. This clean fuel is in turn combusted at high temperatures to generate renewable energy. A typical DTE waste-to-energy plant would process approximately 150 tons a day of wet materials, converting them into both thermal and electric energy. The main technology components are all modular. This allows our engineers to more efficiently design each plant and meet the specific processing capacity requirements of each customer.”
