NSW Minister for Jobs, Investment, Tourism and Western Sydney, Stuart Ayres said Junglefy had partnered with toll road operators Transurban, Government, to build and test live "breathing walls" which promise to absorb pollution and traffic sound, and cool air temperatures.

“Junglefy has received a $100,000 Building Partnerships grant from the NSW Government-backed Jobs for NSW to further test its already proven technology on Sydney’s motorways,” Ayres said.

Junglefy managing director Jock Gammon said the company would test the walls on motorways by installing sensors to monitor and record pollution levels in real time.

Gammon said Junglefy, which started with three staff in 2009 but now has 33, was using its technology to “tap into what mother nature had been doing for billions of years”.

“Jobs for NSW’s support will help fund our research, further prove our technology and pave the way for our expansion internationally,” he said.

“Plants are the lungs of our city so it’s incredibly exciting we now have the chance to work with Transurban and UTS Sydney to test our breathing walls on Sydney motorways after proving their effectiveness on numerous sites nationally.

Gammon said the breathing walls were scientifically proven to remove particulate matter (PM2.5) and volatile organic compounds.

“They also look beautiful, soften our urban environment, make our cities cooler and provide a habitat for biodiversity.

“The resilience of Mother Nature is amazing. During previous research we put plants in polluted containers for five hours a day, five days a week for five weeks and while there was pollution on the leaves, the plants performed and survived just fine.

“Our breathing wall is a modular system that can remove air pollutants faster than any other plant-based system. We want to turn our cities into urban jungles with plants growing everywhere.”

Gammon said two Sydney motorways — the Eastern Distributor and the Hills M2 — would be the “first in the world” to trial the new technology.
