Maryland’s looming waste crisis – an unintended consequence of uninformed environmentalists

Maryland Could See Waste Crisis
After stricter limits on waste-to-energy facilities in Maryland, the state could see a drastic uptick in the amount of waste that needs to be landfilled. If Maryland’s two WTE facilities close, it will add millions of tons of household waste back into the landfill stream. State projections, meanwhile, show that the state’s landfills will be full within 30 years at the current rate – if the WTE facilities close early, that rate would grow exponentially. State officials are hoping that improved recycling can offset the waste flow or municipalities would have to pay to send the waste out of state. At present, Montgomery County pays nearly $1 million annually to send waste to Pennsylvania or Virginia. Castaldi_fnl

Radio event

Please tune in today, Wednesday, July 31, 2019 at 3pm to WHCR-90.3FM to From City to the World, hosted by CCNY President Vince Boudreau.
President Boudreau will discuss sustainability and waste management with Professor Marco Castaldi, the Director of the Earth Engineering Center here at CCNY and a Professor in our Chemical Engineering Department.
On the second half of the show Cheryl Huber, the Assistant Director of Greenmarket, the country’s largest network of outdoor farmers markets will join the conversation. She will discuss her organization’s work with an emphasis on Grownyc’s Zero Waste program.

Chinese delegation visits EEC|CCNY to learn about waste management in the US

14 delegates from the Chinese Urban Waste Construction delegation visited EEC|CCNY to learn about waste management in the United States. Castaldi and Tsiamis presented on EEC|CCNY’s research in all areas of waste management. The visit was coordinated by the U.S. Trade and Development Agency as part of the Clean Energy Exchange. Previous international delegations who have visited EEC|CCNY (through the US Department of State’s International Visitor Leadership Program (IVLP)) include Ethiopia, China, and Bulgaria.

Tsiamis and EEC|CCNY team complete 2019 Reuse Sector Assessment for DSNY

Tsiamis and research associates of EEC|CCNY and New York City’s Center for Materials Reuse (CMR) completed the 2019 Reuse Sector Assessment for the Department of Sanitation of New York City (DSNY).  The purpose of DSNY’s biannual reuse sector assessments is to to provide quantitative research insights into reuse activities in NYC that can ultimately help facilitate increased reuse in the City.  Tsiamis, Rappa, Arapi, Shivenanda, and NYC CMR’s Ms. Laura Novich dove into different areas of reuse research, addressing aspects such as quantification of NYC’s reuse sector, using web-based tools to enable insights into for-profit reuse activity, and understanding reuse behavior.  The final 2019 Reuse Sector Assessment will be published by DSNY in the coming year.

EEC|CCNY Hosts 2018 WTERT Conference 

This past October 4th & 5th, 2018, The Earth Engineering Center at City College (EEC|CCNY) hosted a very successful EEC/WTERT 2018 Conference.  The conference included speakers from around the world collectively representing the global perspective on best waste management practices. There were a total of 120 attendees representing 12 countries across five continents (Belgium, Canada, Chile, China, Colombia, France, Germany, Greece, Italy, Korea, Sudan, UK and US).

The takeaway message from the conference was that the circular economy is coming.  Good engineering will get us there, but until then we will need to strengthen collaboration efforts to manage the growing waste streams properly.

Dr. Castaldi Interviewed by ACC’s Chemical & Engineering News

Plastics have gained significant attention recently due to a number of domestic and international activities. This brings awareness to an issue that we have long been investigating but theoretically and practically with organizations ranging from the US EPA and start-up companies. A new story has been published in Chemical & Engineering News from the American Chemical Society exploring the use of plastic waste for energy generation where Professor Castaldi has been interviewed and quoted.
