The recent reduction of sulfur emissions standards by MARPOL and EPA means that the naval industry will have to use low sulfur fuels and/or modify their scrubber systems. Annette has been with the EEC team for 1 year and is a senior in the Environmental Science and Engineering (ESE) program at CCNY.

EEC|CCNY hosts first interdisciplinary waste workshop, Megacity Waste Management Dialogue, at CCNY
April 25-27, 2016
EEC|CCNY hosted its first workshop at CCNY, Megacity Waste Management Dialogue, that brought together all interest groups in waste management – industry professionals, academia, government agencies, and policy makers – to openly discuss the most pressing topics for waste management in megacities, such as NYC. Attendees were from all around the globe and speakers included Commissioner Kathryn Garcia of the Department of Sanitation of New York (DSNY). The outcome of this conference will be a report compiling the major points from the workshop’s breakout sessions that will serve as a roadmap for sustainable waste management in megacities.

New CCNY chemical engineering undergraduate joins EEC|CCNY team to conduct research on waste plastics
- January 26, 2015
- CCNY sophomore chemical engineering undergraduate, Dane Fearon, joined the EEC|CCNY team to gain laboratory research experience. Dane will learn how to use the variety of analytical equipment in the EEC|CCNY lab and will be the primary experimental researcher for a calorimetry study on the energy content available in non-recycled plastics. The EEC|CCNY team is happy to have Dane on board and we look forward to his participation in EEC|CCNY research.
EEC|CCNY visits Golden Renewable Energy’s plastics-to-oil pilot facility in Yonkers, NY
January 14, 2015
- Professor Castaldi and Ms. Demetra Tsiamis visited the pilot facility of Golden Renewable Energy (GRE) to see the company’s plastics-to-oil technology. GRE’s Renewable Fuel Production (RFP) unit converts non-recyclable plastics (NRP) into oil via pyrolysis. EEC|CCNY will conduct an independent technical due diligence of the GRE process to determine efficiencies, yields, and emissions of the process. EEC|CCNY looks forward to this new collaboration with GRE and is excited for the opportunity to further its experience in commercial waste plastics pyrolysis technologies.
Student from Ossining High School joins EEC|CCNY team to research organic food waste for Regeneron Science Fair Competition
Sophomore high school student, Yoo Shin Tanei, from Ossining High School has recently joined the EEC|CCNY research team. Yoo Shin will conduct research this next year at EEC|CCNY for his Intel Science Fair project. The topic of his research will be quantifying the impact of moisture on the energy content of food waste. The EEC|CCNY team is happy to have Yoo Shin join the team and looks forward to the findings he makes in his research.
DHF visits EEC|CCNY
Dr. Yuuzou Kawahara from Dai-Ichi High Frequency Co. (DHF) visited EEC|CCNY to learn more about the center’s research in corrosion of waste-to-energy (WtE) boilers. DHF is a company based in Japan that specializes in thermal treatment to prevent corrosion in boilers.
Tsiamis presents on waste-to-energy at 2014 Annual AICHE meeting in Atlanta
November 17, 2014
Resident Research Associate, Ms. Demetra Tsiamis, presented on waste sustainability and thermal conversion at the 2014 Annual AICHE meeting in Atlanta, Georgia. Ms. Tsiamis presented to the Research and New Technology Council (RANTC) committee about the current WtE research activities at EEC|CCNY and proposed the addition of a WtE segment to the AICHE conferences in the following years. The suggestion was well-received by RANTC and a dialogue was started on how to make this happen. EEC|CCNY looks forward to collaborating with AICHE to incorporate waste sustainability as part of future AICHE conferences.
EEC|CCNY to conduct extensive study on the heating value of non-recycled plastics in municipal solid waste
November 5, 2014
EEC|CCNY recently finalized a proposal for a study that will determine the representative heating value of non-recycled plastics (NRP) in municipal solid waste (MSW) based on calorimetry testing. The motivation for this study is to address the major discrepancies that exist in the literature with regards to the energy content of NRP. Extensive calorimetry data will be collected for waste plastic samples of all resin types collected from MSW to determine the representative heating value of NRP. Additional objectives of this study will be to determine the impact that contamination, plastic resin type, and product type (film versus rigid) have on the heating value of NRP. This study will be sponsored by the American Chemistry Council.
Mayor of Addis Ababa and Ethiopian delegates visit EEC|CCNY
October 28, 2014
The mayor of Addis Ababa and a delegation of Ethiopian environmental and city planning officials visited EEC|CCNY as part of the International Visitor Leadership Program. The Ethiopian government, in cooperation with a non-profit organization, Horn of Africa Regional Environment Center (HOAREC), are working together to clean and re-purpose a 40-year old dumping site in the city of Addis Ababa. The delegation came to EEC|CCNY to learn about the current research in the recovery of materials and energy from waste and to learn about successful waste management practices in the U.S. that could be applied to Ethiopia’s waste infrastructure.

EPA releases official statement on handling of spent baghouse filters
October 10, 2014
EPA recently released an official statement on the handling of spent baghouse filters at municipal waste combustor facilities. EPA determined that combustion of spent baghouse filters at MWC facilities do not significantly impact emissions from the combustor. EEC|CCNY attributes part of EPA’s final decision to the White Paper that EEC|CCNY and ASME-MER submitted to the EPA in January 2014 on the environmental impact of fabric filter bag incineration. The findings of this technical investigation determined that emissions from the combustor increased by less than 0.2% when processing spent baghouse filters. The difference in emissions was immeasurable within the analytical detection limits of the typical monitoring systems for in-stack emissions therefore it was concluded that combustion of spent baghouse filters do not significantly impact emissions of the combustor.
