IOT (Internet of Things) base Direct Air Carbon

 Project Tittle: IOT (Internet of Things) base Direct Air Carbon Capturing with Air Purifier.

 Project Summary: Dhaka, a city of 23.2 million people, is one of the top five most polluted cities in the world. It suffers from severe air pollution, a lack of trees, and excessive carbon dioxide emissions, which are causing the city to heat up. This pollution is affecting the lower-income people the most. Since there is not enough space left in the city to plant new trees, the Internet of Things (IOT)-based Direct Air Carbon Capturing and Air Purifier will be a way to overcome this problem. One machine will purify the air equivalent to about 1,000 trees and, in addition to absorbing carbon dioxide, will also show the amount of greenhouse gases in the air.

 Project Area: - Around Dhaka City.

 Project Period: 3 years. (From July,2025 to June 2028)

 Targeted Stakeholders: Detailing the primary, secondary and tertiary-

Primary Stakeholders (Directly impacted or involved):

• Low-income communities in Dhaka – most affected by air pollution.
• Children and elderly – vulnerable to health issues.
• City authorities (DNCC/DSCC) – for implementation in public areas.
• Healthcare sector – reduced pollution-related illnesses.

1. Project objective: To reduce air pollution in Dhaka City by deploying Internet of Things (IOT)based Direct Air Carbon Capturing and Air Purifier systems that can absorb carbon dioxide and other toxic gases, equivalent to the air-purifying capacity of 1,000 trees per unit. The system aims to lower CO levels from 480–500 ppm to 250 ppm, improve public health—especially for vulnerable populations and support the production of eco-friendly materials like Eco bricks and Eco- feed from captured carbon.
2. Problem Context:  Dhaka the capital of Bangladesh with a population of 23.2 million, is one of the world’s most polluted cities, facing severe air pollution, excessive CO emissions, and a critical lack of green space. The CO level in the air often exceeds 480–500 ppm, far above the safe range of 350–400 ppm. This pollution is especially harmful to low-income communities and children, contributing to respiratory diseases and premature deaths—up to 88,000 in Bangladesh in 2019 alone. With little space left for tree planting, Internet of Things( IOT)based Direct Air Carbon Capturing and Air Purification system offers a powerful alternative. Each unit can clean air equivalent to 1,000 trees, monitor greenhouse gases, and turn captured CO into raw materials for Eco-bricks and eco-feed, providing a scalable, sustainable solution to Dhaka’s worsening air crisis.
3. Rationale of the project: Dhaka, one of the world's top five most polluted cities with 23.2 million people, faces critical air pollution due to high carbon dioxide emissions, lack of green space, and toxic dust from traffic, construction, and outdated industries. Lower-income populations suffer the most, with alarming levels of heavy metals like cadmium—200 times above safe limits—found in road dust. With limited space to plant trees, the IOT-based Direct Air Carbon Capturing and Air Purifier offers an innovative solution. Each machine purifies air equivalent to 1,000 trees, absorbs 84,000 pounds of CO over 3 years, filters heavy metal particles, and cleans 709,560 kiloliters of air. It protects up to 11,600 people from pollution-related health risks and increases public awareness through real-time air quality data. This project provides a practical, scalable response to Dhaka’s urgent air quality crisis.

1. Project Outcome: The implementation of the Internet of Things(IOT)based Direct Air Carbon Capturing and Air Purifier System will result in significant environmental, health, and socio-economic benefits for Dhaka city:

Improved Air Quality:
Each unit will purify approximately 709,560 kiloliters of air over three years, removing both carbon dioxide and toxic heavy metal particles such as cadmium, lead, and arsenic from the environment.

v  Reduction in CO Levels:
The system will reduce atmospheric CO concentrations from dangerous levels of 480–500 ppm to a safer 250 ppm. Each unit will absorb 84,000 pounds of CO over 3 years.

v  Health Benefits:
Each machine will directly and indirectly protect 1,500–1,600 people from pollution-related health risks, including respiratory diseases and heavy metal toxicity, especially among vulnerable low-income communities and children.

v  Economic Impact:
By reducing air pollution, the system will help lower the average annual medical expense of 350–370 BDT per person, providing financial relief to economically disadvantaged populations.

v  Data-Driven Public Awareness:
Real-time display of harmful gas levels and air quality data will raise public awareness, encourage behavior change, and inform policy decisions.

v  Circular Economy Contribution:
Captured carbon dioxide will be converted into raw materials for eco-bricks and eco-feed, promoting sustainable production and environmental reuse.

Health and Community Impact

• Protect 1,500–1,600 people per machine, both directly and indirectly, by improving air quality and reducing exposure to toxic pollutants.
• Reduce the economic burden of healthcare related to air pollution, especially for low-income communities (saving an estimated BDT 350–370 per person annually).

Environmental and Economic Circular Benefits.

v  Use the captured carbon dioxide to produce:

v  Eco-bricks for sustainable construction.

v  Eco-feed as a byproduct, supporting green industry and recycling.

     Strategic Site Analysis and Installation Planning

l  Identify high-pollution zones based on data and studies (e.g., areas with high levels of cadmium, zinc, and lead).

l  Prioritize installations in areas lacking greenery or with vulnerable populations (e.g., schools, slums, hospitals).

Appeals:

We would like to say only 25 USD has been received in this connection. However, since we have started some necessary interventions VIEW borne the operational cost out of our resources. Without funding support how long  we will continue the intervention is a matter of concern. Some activities have been just started and while others activities will also be taken into consideration to implement. Budgetary funding is necessary to implement the programmes. This project would not have been possible without the kind support and help of donors, friends and any individuals. Every donation, no matter how small or big rather it will makes a significant difference  and building more resilient communities. Together, we can make a real impact and support the project on their path to a better future.
