In a roundtable conversation hosted by The Architects’ Newspaper, four New York City Commissioners–Transportation Commissioner Janette Sadik-Khan, Design and Construction Commissioner David Burney, Planning Commissioner Amanda Burden, and Parks Commissioner Adrian Benepe–discuss recently designed and developed projects as well as what they believe is achievable during Mayor Bloomberg’s next four years, especially given tightening fiscal constraints.

Partners Waste Management and Linde Group have begun processing fuel at the world’s largest Landfill Gas (LFG) to Liquefied Natural Gas (LNG) plant, located at Altamont Landfill near Livermore, CA.  Waste Management–the leading US waste services company and largest national operator of refuse and recycling trucks–collects the garbage, and Linde, an engineering company, purifies and liquifies the LFG produced by the waste. 

The New York City Department of Environmental Protection has identified Greenpoint, Brooklyn’s Newtown Creek Wastewater Treatment Plant as a prime site for methane gas harvesting, a process which has been bringing in approximately $11 million annually from the Freshkills Park site. 

The New York Times surveys the growth of “zero waste” strategies in the US among private companies, institutions and entire municipalities.  “Reduce, Reuse and Recycle” are really coming of age: biodegradable utensils, large-scale composting and citywide, warehouse-like free swap shops.  And it’s not just hippies and treehuggers participating anymore.

The Environmental Protection Agency (EPA) has identified nearly 4,100 contaminated sites nationally, including abandoned mines, disused factories and some landfills, that could be suitable for renewable energy projects–primarily solar and wind power, and some biomass harvesting.  Contaminated sites are considered particularly appealing for renewable energy projects because they are less likely than other sites to be prized for their habitat value.

Researchers at the University of Texas are developing solar photovoltaics 10,000 times thinner than human hair that can be spray-painted onto surfaces.   The ambition of the  project is to develop a solution of sunlight-absorbing nanoparticles that can be sprayed onto a surface to create a solar panel–a process similar to newspaper printing. 

Catalyx Nanotech is the first company to use methane for nanofiber production. Through a demonstration project at a California landfill, the company was able to split methane into pure hydrogen and carbon to produce nanofibers.  Carbon-based nanofibers can be applied to a number of  uses: medical, energy, protection, textile; in this case, they’ll be used for hydrogren fuel supply. 

The 2008 Massachusetts Clean Energy Biofuels Act requires petroleum suppliers in that state to make 2 to 3 percent of their sales, by volume, from biofuels by 2011.  And in a recent decision, the state says that waste-based biofuels are the only ones yet to meet the state’s renewable fuel standards, citing their significantly reduced contribution to greenhouse gas emissions. 

Among Treehugger’s 10 greenest colleges in the US is the University of New Hampshire (UNH), the first college in the country to run primarily on landfill gas.  85% of electricity and gas needs on the 5 million square foot campus are met by methane produced at a private, nearby landfill operated by Waste Management and piped to the school from a cogeneration plant. 

Zero-net energy buildings are designed to be as energy-efficient as possible and to offset what energy they do use through renewable power generation. Some have already been built, like the Omega Center for Sustainable Living in Rhinebeck, NY.  The state-of-the art education center and natural wastewater treatment facility boasts not only zero-net energy use due to its solar array, but also zero-net water use.

A recent history of relative marginalization by design and construction professions is being overturned, according to an article in Architectural Record, by landscape architecture’s ability to weave sustainability into the built environment.  According to the Bureau of Labor Statistics, employment of landscape architects is expected to increase 18% to 26% through 2014, faster than the average of all U.S.

The Science Barge is a touring greenhouse that showcases techniques in sustainable agriculture.  All the energy used by the barge is produced by solar panels, wind turbines and biofuels, and the water used for irrigation comes from stormwater or purified river water.

There are exciting green roof projects emerging all over New York City these days: the experimental setups at the Parks Five Borough facility that we visited last month; The US Postal Service’s brand new 2.4-acre installation of native, drought-resistant plants–reportedly the largest green roof in the country–atop their Manhattan mail processing facility; the green roof farm in Greenpoint, Brooklyn, which has been hosting volunteers and giving lectures since opening this spring.  

We really enjoyed last Friday’s tour of the green roof atop the Parks Department’s Five Borough Technical Services Complex.  The roof is gorgeous and inspiring, and it’s worth checking out our flickr photos (and videos) of the tour if you weren’t able to make it. 

Another constructed wetland system, this time at the Sidwell Friend’s School in Washington D.C.  The Wetland Machine by Andropogon Associates, Kieran Timberlake Associates and Natural Systems International incorporates two self-contained systems to recycle water, one for wastewater and one for stormwater. 

Installation of composting toilets in public facilities is catching on.  In New York City, The Bronx Zoo and Queens Botanical Garden have been operating restrooms with composting toilets, with no need for sewer lines, for the last few years.   The technology in both facilities is made by Clivus Multrum and resembles a conventional toilet, except that it uses only 3-6 ounces of water, in combination with a bio-compostable foam, for flushing. 

The Waterpod is a a certified public vessel, a vegetable and chicken farm, a hodge-podge of sustainable systems (solar panels, rainwater collection, bicyle-produced electricity) and a recycled, floating home for six artists.  They’ve lived there since Saturday and call it “a floating sculptural living structure designed as a new habitat for the global warming epoch.” 

The generous folks at Nikon cut us a sweet deal on a few pairs of their new Ecobins binoculars. They’re manufactured with lead- and arsenic-free glass and built with non-chloride rubber that uses no harmful inks or dyes.  The straps and carrying bags are produced from sustainable eucalyptus and manufactured with minimal waste. 

The Hugo Neu Metals Recycling Facility, in the Hunt’s Point area of the Bronx, is getting a stormwater management makeover. The Gaia Institute’s new system for the 6.5-acre facility recycles stormwater that would otherwise run off into the Bronx River Estuary.

The 30-acre Bethlehem Steel Mill on Lake Erie was in operation for almost 80 years and was closed in the mid-1970s.  Contaminated with steel slag and industrial waste, the site was idle for 30 years.  In May 2002, the EPA awarded the City of Lackawanna a $200,000 grant to investigate the site’s potential for reuse.
