COVID-19 Updates

Dear Attendees,

We are aware that the situation with the COVID-19 pandemic is still evolving and these next couple of months will be very informative.  Currently we are still planning to have an in-person meeting on October 22nd & 23rd provided the University and other guideline permit.  Since the conference will be on The City College campus of City University we will not need to make a decision until late August/early September.  A decision to proceed or cancel will be made then and will include all variables from travel restrictions to campus capacity guidelines.

Please periodically visit our website for updates

Thank you

Conference Chairs: Dr. Jeffery LeBlanc, Anjeza Arapi, Dr. Snehesh Ail, Prof. Marco J Castaldi

Single-use plastics transformed into high-quality liquid hydrocarbons with new catalyst

by Raleigh McElvery, special to C&EN, OCTOBER 24, 2019

All too often, plastics serve a “one-and-done” purpose. Roughly 300 million t of materials are discarded each year after just one use, contributing to waste and pollution. Scientists and businesses have been teaming up to change this, devising ways to transform single-use plastics into products of even greater value. Now, researchers have devised a catalyst capable of selectively converting single-use polyethylene—even from a plastic bag—into lubricants like motor oil or waxes for use in detergents, cosmetics, and more… read more

A recent article in MSW Management from EEC|CCNY Alumna Annette Scotto explores the social issues associated with recycling. The article titled “Is Recycling a Fraud? Why Should I Bother?

The use of social media platforms to educate and inform the public on the processes of modern recycling” discusses how social media can be used to better educate the public on recycling.  Annette and her team determined that the convenient location of recycling bins and a robust education program would likely increase recycling the most compared to other factors such as incentives.  To read more please go to:

A recent article quote Professor Castaldi

Professor Castaldi was recently quoted in a recent Chemical & Engineering News (C&EN) feature. The article by Alexander Tullo presents the issues associated with plastic waste.  The article “Plastic has a problem; is chemical recycling the solution?” published October 6, 2019 C&EN VOL. 97, ISSUE 39 details how new and existing conversion technologies are planning to process the plastic wastes that are not or cannot be recycled.  Currently about 9% of plastics are recycled because the public does not separate their waste enough, the markets for recycled material are weak and product performance dictates exacting properties which recycled material normally cannot meet.  To read more please visit

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.
