Vacuum Trash Collection Could Cut NYC Energy Use

Two studies by University Transportation Research Center at CCNY report benefits of new systems in Manhattan, upgraded system on Roosevelt Island

The solution to noisy, diesel-burning garbage trucks hauling away waste in New York City may lie under the pavement and over the heads of city residents, two new studies suggest. The University Transportation Research Center (UTRC) at The City College of New York produced the reports.

They show the benefits of expanding an existing underground pneumatic garbage disposal system on Roosevelt Island and creating new networks in Manhattan by making use of such existing transportation infrastructure as the Second Avenue subway and the High Line Park viaduct.

The New York State Energy Research and Development Authority (NYSERDA) and New York State Department of Transportation (NYSDOT) funded the studies through a program that explores techniques to reduce transportation-related fossil fuel use.

Pneumatic collection uses negative air pressure to pull solid waste through a network of pipes to a central collection point. There, it is compacted and sealed into containers for transport to a processing or disposal facility. It is not a new idea: the technology has been used successfully in Europe and Asia for more than 50 years. Since 1975, such a system has collected residential trash on Roosevelt Island.

The studies found energy and environmental savings associated with proposals for two new pneumatic facilities that would be installed under the High Line and in the Second Avenue subway. The systems would also improve quality of life and public health by reducing the amount of waste collected from sidewalks. Upgrading the existing system on Roosevelt Island could eliminate trucks that are currently used to collect the island’s recyclables, commercial waste and litter bin waste.

"Governor Cuomo has made innovation a cornerstone to stimulating the economy and creating green jobs. NYSERDA is pleased to once again partner with the Department of Transportation on a project which offers potential solutions to emissions reduction in the transportation sector," said Janet Joseph, NYSERDA vice president for technology and strategic planning. "The state’s investment in such studies demonstrates its commitment to expanding a clean energy economy that can support the technologies of tomorrow."

“Through Governor Andrew Cuomo’s leadership, the State Department of Transportation has partnered with NYSERDA to encourage research projects like this one, which can develop programs and technologies that support economic development, enhance mobility and protect the environment,” said state Commissioner of Transportation Joan McDonald. “We look forward to continuing innovations that improve traffic management and reduce greenhouse gas emissions across the state.”

“Just as the environmental and economic efficiency of conventional, truck-based collection varies with specific local conditions, the costs and benefits of pneumatic systems vary by location,” said Benjamin Miller, UTRC’s co-project manager for the studies. “These studies of three neighborhoods show the benefits that the pneumatic systems now used in hundreds of European and Asian cities could have in specific New York City situations,”

About the University Transportation Research Center (UTRC)
The University Transportation Research Center (UTRC) is a U.S. Department of Transportation Regional Transportation Center addressing surface transportation operations, management, design economics and planning. The Region 2 University Transportation Research Center is one of ten original National Centers, established in 1987, in recognition that transportation plays a key role in the nation’s economy and in the quality of people’s lives.  

Located at The City College of New York, the Center is a consortium of 17 major academic institutions in New York, New Jersey, and Puerto Rico. Through the grant supporting the Center, the mission incorporates research, education and the transfer of technology in the field of transportation. Academically based, the work of faculty and students – graduate and undergraduate — provides a critical link in resolving our national and regional transportation problems while training the future and current professionals who address our transportation system and their customers on a daily basis.
