Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

Matthew Bunn and Will Tobey spoke with Piet de Klerk, the Dutch Sherpa organizing the 2014 Nuclear Security Summit, on October 7 at a United Nations event sponsored by the Dutch mission to the UN. In these slides, Bunn and Tobey provide an updated summary of the threat of nuclear terrorism and recommendations for next steps to reduce the threat, based in part on the new U.S.-Russian report, Steps to Prevent Nuclear Terrorism.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real. This presentation recommends learning from the much stronger national and international efforts in nuclear safety, and in particular, taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level. Matthew Bunn presented this talk, based on a recent paper, on July 3rd, 2013 at the International Conference on Nuclear Security in Vienna.

"...[Y]es, I think Stuxnet had a few down sides. One of those down sides was that the actual attack code became publicly available. As far as I can tell the attack code was supposed to die and not get out onto the Internet, but apparently the same way it got into Natanz [Iranian nuclear enrichment facility], it got out...."

"Getting second-rung leadership right is important for any enterprise, and for al Qaeda that meant assuring the brand and building network capacity for terror. Bin Laden was careful about deciding who would be anointed with two powerful gifts—his blessing of leadership, and formal affiliation of groups to al Qaeda central (a term he heard used by the media and, amazingly, appropriated)."

Matthew Bunn's introduction to the 2012 Nuclear Security Summit.

Matthew Bunn presented "The threat of nuclear terrorism: What’s new? What’s true?" at a conference in Seoul, 3-5 November, 2011.

Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called 'water–energy nexus', is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the MENA region.

"Our crystal ball is not clear enough to predict with confidence whether the global nuclear future will be characterized by peace and prosperity or by conflict and destruction. But we do believe that the choices made in the coming few years will be crucial in determining whether the world can have more nuclear power without more nuclear weapons dangers in the future."

Will the growth of nuclear power lead to increased risks of nuclear weapons proliferation and nuclear terrorism? Will the nonproliferation regime be adequate to ensure safety and security in a world more widely and heavily invested in nuclear power? The authors in this two-volume (Fall 2009 and Winter 2010) special issue of Dædalus have one simple and clear answer to these questions: It depends.
