Abstract
This project, titled "Factory Air Purifier: A Carbon Reducer," focuses on the design and
implementation of an air purification system specifically tailored to reduce carbon emissions
from industrial factories. The primary aim is to address the pressing issue of air pollution
caused by industrial activities, which contribute significantly to global warming and
environmental degradation.

The project explores the integration of advanced filtration technologies, such as activated
carbon filters and electrostatic precipitators, to capture carbon particles an

d other harmful pollutants released during factory operations. The design emphasizes
efficiency, scalability, and cost-effectiveness, making it suitable for large-scale industrial use.

Prototype testing and simulations were conducted to assess the performance of the system in
capturing and reducing carbon-based emissions. The results indicate a significant reduction in
particulate matter and carbon pollutants, demonstrating the system's potential to improve air
quality and reduce environmental impact.

This project highlights the necessity of adopting innovative and sustainable technologies to
mitigate industrial pollution. It offers a promising solution to industries aiming to align with
environmental regulations and contribute to a cleaner, healthier atmosphere.

Introduction

Air pollution is contamination of the indoor or outdoor environment by any chemical, physical
or biological agent that modifies the natural characteristics of the atmosphere.

Household combustion devices, motor vehicles, industrial facilities and forest fires are
common sources of air pollution. Pollutants of major public health concern include particulate
matter, carbon monoxide, ozone, nitrogen dioxide and sulphur dioxide. Outdoor and indoor air
pollution cause respiratory and other diseases and are important sources of morbidity and
mortality.

WHO data show that almost all of the global population (99%) breathe air that exceeds WHO
guideline limits and contains high levels of pollutants, with low and middle-income countries
suffering from the highest exposures.

Air quality is closely linked to the earth’s climate and ecosystems globally. Many of the drivers
of air pollution (i.e. combustion of fossil fuels) are also sources of greenhouse gas emissions.
Policies to reduce air pollution, therefore, offer a win-win strategy for both climate and health,
lowering the burden of disease attributable to air pollution, as well as contributing to the near
and long-term mitigation of climate change. As the global population grows, so does the
demand for manufactured goods, leading to an increase in pollutants released into the
atmosphere. The need for innovative solutions to mitigate air pollution has never been more
critical.

This project focuses on the development of a Factory Air Purifier: A Carbon Reducer aimed
at reducing carbon emissions from industrial facilities. Carbon dioxide (CO₂) and other
greenhouse gases are major contributors to global warming, and industrial activities are among
the primary sources of these emissions. Traditional air purification systems either lack
efficiency or are not widely implemented in factories due to cost or complexity. Hence, this
project explores a practical and cost-effective method to reduce carbon levels using a
combination of filtration techniques and chemical processes.

The proposed factory air purifier incorporates materials like cotton, known for its high
adsorption capacity, along with innovative technologies to trap and reduce airborne carbon
particles. The system aims to contribute to cleaner air and promote environmental sustainability
by mitigating the harmful effects of industrial emissions.
 8

By reducing carbon levels at the source, the project seeks to address both environmental and
health concerns. Cleaner air leads to improved public health, reduced environmental
degradation, and aligns with global goals like the Paris Agreement to combat climate change.
This project demonstrates a proactive approach to tackling one of the most significant
challenges of the modern industrial age.

The methodology section outlines the systematic approach used to design, construct, and test
the Factory Air Purifier: A Carbon Reducer. This section includes details about the materials
used, the working process, and experimental procedures involved in creating the project.

1. Materials Used

The following materials were used to construct the air purifier:

• Processed Medical Cotton: To adsorb carbon dioxide (CO₂) and other pollutants.
• Cardboard Frame and Housing: For supporting and enclosing the purifier system.
• A 12V Air Fan/Gas Fan: To create airflow and direct emissions through the filtration
system.
• A 12V AC to DC Converter Adapter: For operating the air purifier.

• A Plastic Box: For keeping the purifier system (including cotton, water and metal wires)
• A Tube of a Tire: For producing black smoke full of carbon.

2. WORKING MECHANISM

The air purifier works on a two-stage purification process:

1. Collection of Airborne Pollutants

▪ Factory emissions are drawn into the purifier using a high-capacity 12V Air Fan
▪ A standardized piping system channels the polluted air into the purifier for
treatment.

2. Filtration and Carbon Reduction

a. Stage 1 – Activated Carbon Adsorption:

▪ The polluted air passes through activated cotton filters, which adsorb Carbon
and other dust particles.
▪ Processed Cotton works through a process called adsorption, where pollutants
adhere to the surface of the Cotton material.

b. Stage 2 – Purified Air Release:

c. The clean air, now free of carbon and particulates, is released back into the
atmosphere.

3. EXPERIMENTATION AND TESTING

• A prototype of the factory air purifier was set up in room temperature in a room.
 11

• Steps Followed:
1. Simulated factory emissions were generated using a mixture of smoke and gases
from tire tube.
2. Polluted air was passed through the air purifier system.
3. Data such as purification efficiency were physically recorded and analyzed.
• Testing Parameters:
o Carbon Reduction Efficiency: The percentage of Black Carbon decreases after
purification.
o Airflow Rate: To measure how much air can be purified per unit of time.

4. DATA COLLECTION AND OBSERVATION
