·  In the first part of the morning of November 14 there were presentations on waste management in NYC

- Mr. Scott Kaufman (Columbia) discussed  paper recycling in NYC.

- Monica DeAngelo (Columbia) presented the results of her research on use of GIS in siting new WTE facilities.

- Mr. Ben Miller (Earth Engineering Center) discussed lessons learnt from the 1992 Comprehensive Solid Waste Management Plan for NYC.

 

General discussion on WTERT goals for 2004

· All participants were asked for suggestions and comments as to what should WTERT do in the following year to advance the recovery of energy and materials from solid wastes. Prof. Themelis mentioned that in some other nations there were research institutes whose objective was to advance the Integrated Management of Wastes, i.e., recycling, composting, combustion and any other means that reduced the amount of wastes to be landfilled.  WTERT was attempting to fulfill this role in the U.S. and also link with other research centers around the world.

The principal areas of WTERT concentration at this time were

a)      beneficial use of ash (coordinated by the Ash consortium and Dr. Karsten Millrath (please contact km516@columbia.edu)

b)      minimization of corrosion in combustion chambers (co-ordinated by Mr. Dionel Albina at Columbia (please contact doa2001@columbia.edu).

-Ms. Maria Zannes, the president of IWSA, stated that the main functions of WTERT should be research, training, and education. It allowed engineering students to consider all aspects of Integrated Waste Management. Communication with peers in academia, with technical people in industry and with the international WTE broadens the perspective of all WTERT members. The Council is a non-profit organization but money must be provided to support the graduate students who are engaged in WTERT research.

-Prof. Themelis stated that the presentations by various faculty and graduate students at this meeting demonstrated the breadth of research activities undertaken by WTERT.

-An environmental engineer from California commented that WTERT is well positioned to disseminate information on WTE and IWM. This information should be in a format that is understandable by the general public.

-Another participant agreed with the statement made by Prof. Sachs that the School of Public Health should be brought into the picture so that the public understands better the health implications of WTE, landfilling, etc. 

- Mr. Edward Kurtz (a specialist in communication) suggested that an effort should be made to find out why WTE is being opposed by the public (e.g. in NYC). What does the public need to know to convince them one way or another?.

- Mr. Greg Epelbaum (Chief Engineer, American Ref-fuel) said that the major problem with public perception of WTE is ignorance of some basic facts such as how electricity is produced, the downside of landfilling, etc.

- Dr. Juergen Vehlow (Research Center at Karslsruhe) commented that effective dissemination of information to the public is key, since political action follows public perceptions.  WTERT, as an independent, academically-led group is in a strong position to inform the public. WTERT should participate in public hearings where waste management is discussed.  It is a long process but WTERT can illuminate the ongoing discussion with technical facts..

- Prof. Themelis stated that WTERT is already influencing the debate about WTE in New York City(e.g., NYC Council has recently held a meeting on the latest technologies for WTE).

-One of the registrants commented that it is essential in the debate to include economic considerations with regard to various competing technologies. “Usually, money talks!”

- Mr. Scott Kaufman (Columbia) stated that a small part of the community, those who have strong positions against technology, bother to attend public meetings. Thus, the discussion is not rational and the vast majority is not represented.

- Prof. Xiadong Li said that in China, the government has very strict rules in siting WTE facilities. The National Research Center publishes reports and data as to where WTE plants should be placed. In order to strengthen the case for new WTEs, they bring members of the community to already existing plants. This helps people to think positively about new plants. The scientific community has a major role in this process.

- Ms. Zannes said that U.S. WTE facilities operating under the MACT regulations  bring skeptical people to their WTE plants, where they can see for themselves that there are no odors, etc.. This is the best way for changing peoples’ mind.

- A senior operating engineer (ARF) commented that visits of the graduate students working with WTERT should be arranged to existing WTEs so they can see for themselves what is happening. The facility is a big seller by itself.

- Mr. John Austin (ASME) commented that in siting new WTEs it is very important to consider effects the community, such as property values, financial stakes, and public health.

- Another registrant questioned whether such effects are considered when new landfills are sited.

- Mr. Larry Beaumont (EAC) applauded the idea of WTERT interdisciplinary studies (health, society, sustainable development) suggested by Prof. Sachs in his opening address.

- Mr. Edward Kurtz  suggested that the School of Architecture should be involved in the design of new, esthetically pleasing WTEs.

-Prof. Themelis pointed out that there is a need for funding the academic research of WTERT. He also mentioned that there would be a modest registration fee for next year’s WTERT conference.

- Mr. John Skinner (SWANA) said that generally there are public misconceptions with regard to new technologies and WTERT can serve a very useful role in this regard.  It was reasonable to have a registration fee for future WTERT meetings.

- Dr. Fabrice Patisson ( Ecole des Mines de Nancy, France) commented that the public is not sufficiently informed about WTE. His research center may join WTERT and representation should be sought form other universities around the world.

-Mr. Robert Giraud (DuPont, working on industrial and hazardous wastes) stated that the input of WTERT in the national debate re waste management is good . However, the Council should focus on certain major issues and not try to cover all the subjects that had been mentioned.

The next WTERT meeting in New York City is scheduled for October 7-8, 2004 

Also,WTERT is a co-sponsor of the next NAWTEC 12 meeting in Savannah, Georgia (May 17-19, 2004).
