what delhi can learn from beijing, mexico, hong kong, manilla - air purifier manufacturer
When I woke up on the morning of November 8, 2017, the red tearful gasps, and I was counting my blessings.
I live in a house with air purifiers, travel in closed cars and work indoors.
Delhi's large population is not so fortunate-homeless, slum dwellers, labor and informal workers work hard every day for their daily wages in the toxic air.
Real-time data of air quality index (AQI)
A popular air pollution indicator shows that pollution levels in northern India are the worst in the world, and Delhi is only defeated by Haryana at AQI levels.
Several academic papers and articles devoted to the reasons for Delhi
NCR winter pollution such as waste incineration, vehicle traffic, lack of public transport, industrial emissions, overpopulation, etc.
However, at this moment today, Delhi is facing a wide range of environmental crises, resulting in public health emergencies and accidents due to lack of visibility (
Such as a car accident involving 24 cars in NORDA).
It is necessary to focus on solutions that can truly address crises of such a scale.
This is where technology enters the picture.
In the face of similar crises, cities around the world have taken a clean
Technical solutions are an integral part of their plan to deal with air pollution.
Let's take a few examples.
On September 29, 2016, the world's largest air purifier made its debut in Beijing and was installed for 41 days.
The smoke-free Tower was designed and conceived by Dutch innovator Daan Roosegaarde to absorb polluted air, including the Super
Fine particulate matter-treat it and then release clean air.
The tower is 7 m high and can clean 30,000 m³ air per hour through its patented ozone, with more than 75% harmful particulate matter
Free Ion technology
The tower uses less than 1,200 watts per hour, equivalent to a teapot or water heater.
Interestingly, it collects contaminants and concentrates them into small cubes, which are then used by Roosegaarde Studios to make jewelry and cufflinks-famous smoke-free diamonds. In its 41-
During the one-day trial period, research showed that the tower cleaned up about 30 million cubic meters of Beijing air, equivalent to the volume of 10 Beijing national stadiums, and the air around the tower was found to have been cleaned about 55%.
The smog-free Tower is conveniently accessible and can be brought into cities with serious air pollution such as Delhi.
In addition, in cooperation with local manufacturers, more towers are being produced in China. Smog-
The city, known as smog, is eating buildings --
Manuel Heya Gonzalez hospital in Mexico City "eat architecture" has taken the word green architecture to a whole new level.
As part of the government's ProAir program to prevent urban pollution, the hospital's wall has created a 2,500-square-meter facade, using paint-coated modules, when exposed to ultraviolet rays, these modules can break down air contaminants.
The pigment is still active for about 10 years and can reduce pollution equivalent to 1000 cars in the city.
These specialized modules are designed by the elegant decoration of Berlin with a full range
Directional geometry, capturing sunlight from all directions and better distributing contaminants on the surface-in short, maximizing efficiency through aesthetic appeal!
Smart tree, Hong Kong imagine that if a tree is so efficient, its environmental benefits are equivalent to the forest!
The first smart tree in Asia is a city tree installed in the bustling area of Wan Chai, Hong Kong. in this city, space is very precious.
Powered by solar panels, each city tree is a stand-alone vertical structure, 4 m high and 3 m deep, which can provide clean air equivalent to 275 trees.
The tree, created by Greentown solutions, Germany, uses specially grown Moss cultures and vascular plants that can capture 240 tons of carbon dioxide per year.
The digital system is embedded in the tree for easy monitoring and maintenance.
Data collected from trees are also used for air quality research.
However, the cost per tree is $25,000, and to reduce the cost, the logo and screen can be connected to advertise on the unit. Smog-
Edible paint, ManillaPhilippines developed a home
A solution to its pollution problem.
Epifanio at los Santos Avenue or EDSA is a 24-
Cover the km highway around Manilla.
It is estimated that 2 million cars pass the highway every day, a hotbed of vehicle pollution.
A local company called Boysen has developed a catalytic coating with smoke.
Then the paint was used to make air.
Clean paintings and artwork along the walls of the EDSA highway.
The murals cover an area of about 11,000 square feet and absorb pollution from up to 1,000 trees along the highway.
Studies conducted shortly after the completion of the project in 2013 showed that air quality in the EDSA area improved by about 20%.
Since then, 10 such air cleaning art projects have been carried out throughout the city.
Other-new cleaning in the pipe-
Technological creativity is in the pilot phase and is likely to become a reality in the near future.
Following Milan and rausini, archtitect Stephano Boeri of Italy is designing vertical forest towers in Nanjing, China, accommodating more than 1,000 trees and 2,500 shrubs, producing more than 60 kg per day
Agora Garden is a commercial and residential building covering more than 450,000 square feet. it will build 23,000 factories in Taipei city, absorbing 130 tons of carbon dioxide per year.
In addition, the Dutch innovator of the Envinity Group developed an 8-meter-long air
A vacuum cleaner that cleans 80,000 m³ air per hour with a capacity of 300-metre radius.
While these are just a few examples, scientists and researchers around the world are rapidly testing some new innovations.
It is necessary to understand the applicability of cleaning --tech for Delhi-
Pollution levels and seasonality of the NCR study its financial and economic feasibility and, if feasible, promote its introduction through appropriate models such as public-private partnerships.
That being said, so is it-
I know these cleaning
Technology solutions are not magic pills, but part of a comprehensive plan.
These will be complementary to other solutions, including :(1)
Encourage farmers to stop burning crops by purchasing crop residues at a small cost; (2)
Improve the one-mile and last-mile connection to the subway; (3)
Expanding the subway network, especially underground lines; (4)
Improve traffic management and reduce pollution
Scenic spots due to congestion; and (5)
Create supportive infrastructure for electric vehicles.
Most importantly, none of these solutions will work unless we all do our part to estimate our carbon footprint and start giving up some luxury goods to live more sustainably.
This is our responsibility and let's stop blaming Delhi.
