Figure 1. Deaths caused by air pollution according to WHO


According to the European Environment Agency, air pollution is currently one of the greatest environmental risks, especially in densely populated large urban areas and heavy industry parks. The United Nations Environment Program (UNEP) and the World Health Organization (WHO) indicate pollution causes nearly 7 million premature deaths each year (Fig. 1), of which, according to the European Environment Agency, nearly 500.000 deaths occur in Europe and is reducing life expectancy of Europeans by more than 1,5 years.

According to the WHO. The most concerning air pollutants are particulate matter and nitrogen oxides (NOx = NO2 + NO), and among this nitrogen dioxide (NO2). Due to its high concentration, the physicochemical characteristics of particulate matter cause damage to several organs and systems in the human body. NO2 is highly toxic to human health and shows up in the urban area tropospheric level environments, because of photochemical reactions, as a precursor to other polluting substances.

WHO conclusions

The World Health Organization, supported by several scientific studies, concludes that:

    • The high levels of NO2 found in North American and European cities can impair lung function.
    • Long-term exposure to particulate matter and nitrogen oxides increases risks of respiratory and cardiovascular diseases, as well as neurological injuries. Populations most at risk are under 18 years old and over 65.
    • These pollutants cause damage to the respiratory tissue (from oxidative stress) and hinder immunological responses to pathogens and viruses.
    • Exposure to NO2 exacerbates problems associated with respiratory diseases of viral or bacterial origin, while particulate matter can help propagate these pathogens.

Approximately 85% of Europeans live in urban areas, and they spend almost 90% of their time within indoor spaces.  The concentration of pollutants in these indoor environments is significantly higher than outdoors and aggravated by poor ventilation where, additionally, you may find combustion processes (carbon or natural gas.

Air pollution caused by particulate matter and NOx is a factor contributing to health problems associated with COVID-19, a pandemic responsible for millions of fatalities worldwide and particularly in urban areas.

Health effects

Carbon dioxide (CO2) is one of the main greenhouse gases, a phenomenon that also impacts human health. The American Society of Heat, Refrigerating and Air-Conditioning Engineers (ASHRAE) created a reference chart (Fig. 2) indicating impact on human health associated with various CO2 concentration levels within indoor spaces.

Figure 2. Effects on human health for various CO2 concentrations in parts per million (ppm) according to ASHRAE.

Studies conducted of exposure to CO2 concentrations greater than 1000 ppm, confirm the following observations:

  • Carbon dioxide concentrations between 1.000 ppm and 2.500 ppm hinder cognitive performance and decision-making effectiveness (Fig. 3)
  • Between 2.500 ppm and 3.000 ppm, CO2 can increase stress levels and a feeling of difficulty breathing.
  • Prolonged exposure to CO2 concentrations above 3.000 ppm is considered to be high-risk to human health.

Figure 3. Decision-making performance on humans exposed to various concentrations of CO2.

These are alarming results, especially considering that CO2 concentrations in indoor spaces (residential, office, school, among others) can very quickly reach 1.500 ppm and, in some cases, over 3.000 ppm in just minutes.

Poor indoor air quality can hinder learning in academic environments and work performance, negatively impacting safety and productivity of organizations.

Growing demand for air conditioners: increased demand for energy

Beyond health problems associated with poor indoor air quality, current heating and refrigerating systems used in air-conditioned indoor spaces represent approximately 40% of energy demand of residential, office, and commercial spaces. Some estimations (Fig. 4) suggest a rapid increase in air-conditioning (HVAC) systems installed worldwide because of increasing climate extremes, and this leads to higher global energy demand which currently is linked to greenhouse gas (GHG) emissions.

It is worthwhile mentioning that a significant portion of energy requirements in HVAC systems is associated with climatizing external air that is injected into indoor spaces to dilute CO2 concentrations generated by occupants CO2 generated during breathing. Not only does this require considerable energy but can also add pollutants from urban areas into indoor spaces.

The technological innovation from Ecological World of Life: ANA® INDOOR

To address the need to improve indoor air quality (IAQ) for better health, Ecological World for Life (EWL) has developed a technology that not only neutralizes NO2 and allows the capture of particulate matter, but also transforms CO2 into value-added high-purity carbonates. ANA® provides “A New Air” to Indoor spaces.

ANA® Indoor technology includes a filter for particulate matter and aerosols (which carry viruses, bacteria, and other microorganisms), and an innovative patented cartridge (Fig. 5) where the CO2 and NO2 transformation into innocuous substances takes place.

Figure 5. Prototype ANA® INDOOR cartridge.

ANA® technology can be integrated into a variety of small (Fig. 6) or large HVAC systems, such as used for residential spaces, classrooms, office space, hospitals, and health centres, shopping malls and other commercial spaces, etc.

ANA® is a pioneering CCU technology, based on direct atmospheric capture of CO2 in indoor space, and transforming it into value-added carbonates as raw materials for various industries. ANA® is definitely a sustainable environmental and financial solution.

ANA® INDOOR technology advantages:

ANA® INDOOR technology for residential, commercial, office, and other buildings dedicated for public uses (transportation, entertainment, or medical treatment), offers the following advantages:

    • Our chemical converters are in solid state and highly selective to capture CO2 and NO2 in atmospheric conditions and ambient temperature.
    • The CO2 and NO2 capture/transformation reaction takes place in one step.
    • The capture process only requires air to Flow through the patented cartridge, which can be provided by HVAC air-handling units.
    • ANA® INDOOR cartridge captures and transforms all the CO2 flowing through the chemical converter into solid high-purity carbonates, as has been scientifically proven.
    • ANA® technology allows using various chemical converters in the cartridge to produce different carbonates (Na2CO3, K2CO3, CaCO3, MgCO3).
    • Efficiently removes NO2 at ambient temperature and without the need for expensive catalysts, which implies not only a favorable carbon footprint but also significant economic savings.

The results of ANA® INDOOR

ANA® technology has been validated through rigorous scientific studies5, to effectively reduce CO2 concentration (Fig. 7) y eliminate NO2.

Technical/financial viability and environmental studies conducted by the ‘Instituto Madrileño de Estudios Avanzados – Energía (IMDEA-Energía)’, in collaboration with the Silesian University of Technology, concluded that the CO2 and NO2 capture with ANA® technology reduces external air renovation requirements for indoor spaces, improving IAQ and generating significant energy consumption savings (approximately 30%) for HVAC systems (Fig. 8), which represents a reduction in the carbon footprint of 16.6 kg CO2eq/m2/year.

Figure 7. ANA® INDOOR prototype CO2 capture efficiency in a hermetic indoor space. Once capture begins (t = 0), the CO2 concentration reduces consistently so that, within 7 minutes, reaches atmospheric concentration, and reaches 0 ppm within 12 minutes.

Commercial Vision

We focus on building business-to-business (B2B) relationships with HVAC manufacturing companies considering including or improving their air purification products, integrating ANA® as a component in already installed HVAC equipment and new products developed for the market. This will be possible on portable computers and even integrated central systems.

It is a win-win strategy. The sales growth of our licensees will imply the growth of EWL, increasing our presence in the market.

EWL Business Model

ANA® INDOOR technology can easily be integrated into new and existing HVAC systems, which provides competitive advantages for HVAC manufacturers while supporting their strategic objectives of improving energy efficiency of their portfolio offer.

Additionally, the ANA® INDOOR cartridges are a reusable consumable that provide the opportunity to develop a new and profitable revenue stream associated with cartridges supply for HVAC manufacturing and service providers. The logistics of supply designed to recuperate cartridges once the chemical converters are transformed allows to obtain a high purity “green” carbonate with commercial value to various industries. The sale of “green” carbonates funds purchase costs of chemical converters to refill the reusable cartridge, while the contribution margin generated from sales contributes to cover logistics costs.

The sale of “green” carbonates not only creates a profitable circular economy, but also allows to quantify the amount of CO2 removed from the atmosphere, which can be computed into a reduction of the consumers carbon footprint.

Summarizing, HVAC manufacturers can benefit by incorporating ANA® INDOOR technology through:

    1. Launching a new technology into the market that is aligned with UN’s Sustainable Development Goals and meets European Indoor Air Quality regulations while providing competitive energy efficiency on their products, all strong arguments to support HVAC manufacturer’s sales and profitability growth.
    2. New and profitable consumables revenue stream generated through sales of reusable ANA® INDOOR cartridges for consumers, supporting a profitable circular economy model already proven successful by other companies like, for example, ink jet printer cartridges supply.
    3. Sale of value-added “green” carbonates to the market, supporting a circular economy and allowing to quantify carbon dioxide removed from the atmosphere, therefore reducing the carbon footprint of consumers that purchase HVAC systems with ANA® INDOOR technology, or retrofitting it into their existing HVAC systems.

Ecological World for Life recognizes the complexity associated with reverting the climate crisis and its impact on the environment that life on earth requires, and from the beginning understands that the solutions involve an inter-disciplinary effort within the scientific community and industrial partners to rapidly deploy ANA® solutions to as many people as possible. To that purpose, we propose commercial alliances with HVAC manufacturing companies that will allow improving indoor air quality to the benefit of occupants’ health, as well as creating energy consumption savings by integrating ANA® INDOOR technology to existing and new equipment installations.

EWL business model is based on licensing ANA® INDOOR technology to HVAC system manufacturers that will incorporate it into their product portfolio.  Licensees will use their sales and service network to supply the technology to new and existing systems and develop logistics to supply reusable ANA® INDOOR cartridges to consumers. ANA® INDOOR cartridges provide a new and profitable revenue stream for licensees, while the energy savings to consumers makes installing ANA® INDOOR technology into their new and existing HVAC systems an attractive cost savings investment.

ANA® proposes a Win-Win strategy to our potential commercial partners. HVAC offering benefits from IAQ and energy efficiency of their systems by incorporating ANA® INDOOR licensees to their product portfolio, while EWL obtains funds to continue developing technology solutions for various fields of application focusing on protecting and reverting the climate crisis at hand.

Partnerships and business Development

EWL is inviting regional and global HVAC manufacturers to establish licensing agreements to incorporate ANA® INDOOR and leverage the following advantages:

  • Add a pioneering technology to improve IAQ capturing, neutralizing, and transforming particulate matter, nitrogen dioxide, and carbon dioxide while increasing energy efficiency of their HVAC systems.
  • Incorporate a technology that is directly aligned with United Nations’ SDG.
  • Generate a new and profitable revenue stream through supply of ANA® INDOOR cartridges to consumers that creates value from a circular economy model.

Ecological World for Life Will license use of our ANA® INDOOR technology to HVAC manufacturers that will safely and speedily propagate the technology in the markets in which it operates.
