19th Annual North American Waste-to-Energy Conference Lancaster, Pennsylvania

Michael Jakuttis presented the current situation and development in the European Union

Lancaster, 16th of May – The 19th Annual North American Waste-to-Energy Conference (NAWTEC) was held from Monday the 16th of May to Wednesday the 18th of May in Lancaster, Pennsylvania focusing on the topics “Policies that Promote WtE”, “Modeling”, “Conversion Technologies”, “Case Studies of Small and Publicly Operated Facilities”, “Improving Plant Operations”, “Contract Negotiations and Project Development” and “Advanced Air Emissions Controls”.

The conference was organized by The Solid Waste Association of NorthAmerica (SWANA). Overall the conference was visited by more than 400 people. The main focus of the conference was to promote waste to energy. Therefore Michael Jakuttis explained the current situation and development in the European Union, especially the situation in the EU-12 to the audience.

The conference ended with a visit to the Lancaster County Resource Recovery Facility. The COVANTA plant is located on the banks of the Susquehanna River and began the commercial operation in May 1991. The facility processes 1,200 tons-per-day of solid waste which generates 35.7 megawatts of renewable energy with one condensing steam turbine. The energy is sold to GPU Energy. The facility is a "zero discharge" facility, which means that all the wastewater generated on-site is treated and reused in the waste management process. The facility also uses secondary sewage treatment effluent from a nearby treatment plant for all of its process water. As part of the facility, there is also a public drop-off center where residents can bring non-hazardous household items for disposal. But perhaps the most important aspect of the facility is that it reduces by 90 % the volume of waste that needs to be disposed of at the nearby landfill, thus extending the life of the landfill.


The energy-from waste system used in the plant are three 400 ton-per-day waterwall furnaces with Martin® reverse-reciprocating grates and ash handling system. The boiler is designed for 865 psig (60 bar) and 830 °F (443 °C) superheater outlet conditions. The air pollution control equipment consists of a semi-dry flue gas scrubbers injecting lime, a fabric filter baghouses, a furnace dry-lime injection system, a nitrogen oxide control system, a mercury control system and a continuous emissions monitoring (CEM) system.
