The big rig through the chimney will certainly not make Chicago's roads look like the greenest streets in America.
But their tires are rolling in the smoke.
Eat sidewalks, street lights run under the action of solar and wind power, sidewalks are made of recycled concrete and shrubs
Filled with "bio-sewage" keeps the rain from overburdened sewers.
"Sustainability is critical to us," Karen Weigert, Chicago's chief sustainability officer, told AFP.
"We think it's part of the quality of life, it's about what kind of jobs we attract and economic opportunities to manage taxes.
"Fengcheng has been experimenting with greener urban planning methods for years as part of a broader plan to mitigate the effects of climate change: stronger storms and more extreme temperatures.
$14 million to rebuild two miles (3. 2 kilometers)
In the industrial Bilson neighborhood, almost everything that urban planners can come up with to cut energy use, prevent pollution, reduce waste, manage water and help build community awareness is included.
Surprisingly, it is 21% cheaper than the traditional road re-laying project and is expected to cost less maintenance.
"These are key issues for cities to address," said Karen Hobbs, water analyst at the Natural Resources Conservation Council.
Heavy rain washes away pollution from roofs, roads and parking lots, which often end in rivers and lakes that supply drinking water.
If the rainwater pipe is flooded, the original sewage may also be flooded.
Planting more trees, shrubs and grass belts not only helps prevent rain from entering the sewer, but also helps capture carbon dioxide and reduce the "island" effect of the Sun
Soaked asphalt usually makes the surrounding environment more comfortable.
Improve public transport, increase bicycle lanes, reduce congestion and improve quality of life while reducing pollution.
Reducing energy consumption by using more efficient street light bulbs or installing small solar and wind power stations can not only help reduce emissions, but also save money.
Chicago is one of the growing number of cities that no longer wait for the federal government to deal with climate change, but are looking for local "no.
Hobbs said: "Regret" solution.
"In other words, those activities that save money for residents and businesses, improve quality of life and reduce emissions as an additional reward," she added . ".
However, Chicago says it is the first city in the country to let go of smog. eating cement.
This seemingly magical material was originally developed when the Vatican wanted to build a church to celebrate the 2 th anniversary of Christianity, and it would remain White in the face of Roman pollution.
Italian cement giant Italian cement has developed a product that uses titanium dioxide to trigger chemical reactions with sunlight to clean the church surface by speeding up the decomposition process.
They found that it was not only to clean up the dirt when diving at the church of misserico, but also to clean up the air up to 8 degrees. 2 feet (2. 5 meters)
Above the surface of the roof.
Because it is much more expensive than the traditional sidewalk, Chicago is using it along the bike and parking lanes of Blue Island Avenue and Cermak Road.
Project manager Janet atarian insists that despite the smog
Eating paving materials leaves a deep impression, a comprehensive approach that will have a real impact.
"I really hope this project will inspire people to think about the various opportunities available," Attarian said during a live visit . ".
"We tend to take the road for granted, like 'Oh, it's just a road, what can we do.
But there are actually a lot.
"Reducing the impact of rain on sewers is as high as 80%, meaning the city is expected to prevent or at least delay millions --
The dollar upgrade of its aging system.
Recycling 60% of the construction waste of the project and sourcing 23% of new materials from the recycled content means that the city's landfill is under less pressure and shows a new cost reduction to local contractors
Choose drought
For biological swamps, resistant plants mean they should be able to withstand predictions of hot summer months caused by climate change without wasting fresh water.
Other details are more focused on community building, such as benches by the pond, capturing rain from high school roofs and courtyards, the new waiting booth at the bus station and the sign describing the project's streets up and down.
The city is currently drafting new guidelines to incorporate many of these green approaches into the requirements of any new road work in the future.
"These infrastructure projects last for 100, so you can't redo them again when you finally solve them," Attarian said . ".
"You have to design for the future, not just for the present.
