According to a study released by scientists at Columbia University, landfills across the country contain enough plastic waste to provide power for 5.2 million American homes, fuel six million cars for a year, and potentially much more.

The report indicated that 6.5 percent of used plastics in the U.S. are recycled, 7.7 percent are “combusted with energy recovery,” and the remaining 85.8 percent end up in a landfill. If all the non-recycled plastics were used as fuel in waste-to-energy facilities, the electricity output could potentially power millions of homes and cut coal use by up to 34 million tons.

Although the rate of plastics recycling in the U.S. has increased over the years, projects like this would help recover the energy value from the millions of tons of plastic waste that mostly ends up in landfills. "We have to think of all possible alternatives when it comes to energy, not just solar and wind, but also the untapped resource in waste - particularly plastics - that is valuable energy,” stated Marco Castaldi of the Department of Earth and Environmental Engineering at Columbia University.

Complementing recycling with energy recovery will not only play a crucial role in landfill waste diversion, but also produce power with less of an environmental impact than any other source of electricity, according to the EPA.

While Europe and other countries are already ahead of the game in the development of waste-to-energy technology, the U.S. Congress is starting to take steps in this direction. Earlier this month, the Capitol announced it will be sending all of its non-recyclables to a local waste-to-energy facility, which is expected be more cost effective than composting and save American taxpayers tens of thousands of dollars.

The study noted that projects like this will be crucial in identifying alternative fuel sources for policy makers and stimulating awareness of the need for more waste-to-energy facilities.

Next Energy Technologies has delivered its energy-generating prototype window wall to Bouygues Construction in Paris

Next Energy Technologies, makers of a proprietary transparent PV coating that transforms commercial windows into energy producing solar panels, has delivered its PV Prototype Window Wall to Bouygues Construction in Paris.

Bouygues is a leading construction firm that specialises in complex commercial projects and the deal comes weeks after Next announced its $13.4 Million Series C round of funding (click here).

The PV Prototype Window Wall was delivered by NEXT in collaboration with its partners, Walters & Wolf, a leading commercial curtainwall manufacturer and glazing subcontractor headquartered in Fremont, California, and commercial glass fabricator, Glassfab Tempering  Services/Solarfab in Tracy, California. 

“NEXT’s technology is both unique and promising. We’re proud to support their collaboration with Bouygues Construction and will continue to work side by side with them in bringing their product to market,” said Nick Kocelj, President of Walters & Wolf.  

“We support NEXT Energy in their focused effort in providing a unique and innovative product to  the architectural market. When presented the opportunity to participate in this project, we were  eager to assist in any way possible”, said Brian Frea, President of Glassfab Tempering Services/ Solarfab. 

NEXT’s proprietary transparent PV coating transforms commercial windows into  energy-producing solar panels by converting unwanted infrared and UV light into electricity. This fully integrated system can help enable buildings to power themselves with their windows which  retain their traditional transparency and performance. 

The prototype installation consists of 10 transparent PV windows that supply electricity to a battery that powers an interactive display as well as auxiliary charging outlets, for phones, tablets and other electronics.

The purpose of this prototype demonstration is to showcase the  power generation functionality, the exceptional transparency and aesthetics, and the seamless  integration of NEXT windows into a standard glazing system designed by Walters & Wolf to  carry the electronics, wiring and hardware that comprise the balance-of-system. This direct integration into traditional commercial window and framing systems effectively extracts costs  typically associated with packaging and installation of solar. 

Installed in a typical commercial high-rise office building, the first generation of Next windows would offset as much as 10-20% of its power needs, and over a 30-year timeframe, such a building would produce about 20 million kWh of clean power, saving an average of $170,000  annually on utility bills and reducing 14,500 metric tons of carbon dioxide from the atmosphere, the equivalent of powering 1,700 homes for an entire year. In the coming years, Next windows will be commercially available for window sizes up to 5 ft. x 10 ft (1.5 x 3 meters).  

Supply Chain solution to the climate crisis 

Next’s PV coatings are applied to commercial windows during the window fabrication  process, integrating with existing manufacturers without disrupting established workflows and  supply chains. This capital-efficient business model reduces risks to customers, removes  barriers to adoption, and accelerates speed to market, all while adding a high-value product to  the market. This direct integration into traditional commercial window and framing systems  effectively extracts costs typically associated with packaging and installation of solar.

"We are excited to be one of the first global construction companies pioneering NEXT's revolutionary transparent solar panel windows. This innovation will allow Bouygues Construction to offer its clients a simple, sustainable, and profitable solution for buildings that are autonomous in the management of their energy," said Christian De Nacquard, R&D and Innovation Director, Bouygues Bâtiment International.

The EU aims to be climate-neutral by 2050, requiring a fundamental transformation of the construction and building sectors, and 100% of new commercial buildings in California will be designed to zero net energy (ZNE) standards by 2030. Globally, buildings generate an estimated 40% of annual GHG emissions.

“Addressing the climate crisis at the corporate level requires creative and cost-effective solutions. Commercial buildings are an excellent example of something that can be re-imagined and improved to reduce carbon emissions and overall impact,” said Daniel Emmett,
CEO of NEXT. 

“At a more personal level, we’re seeing employees returning to office buildings after more than a year of lockdown vocally prioritise healthy and sustainable work environments as a requirement of in-person work."

In a recent survey, 74% of employees said they would consider changing jobs if their company did not meet their requirements for a healthy and sustainable office environment, added Emmett.
