The indoor Biosphere as the preparation for the next generation-built environment

The 20th century has given us the built environment of today. Ventilation and filtration practices, energy efficiency, smart materials, sustainable practices, thermal and acoustic comfort. We present in this statement the next stage for the built environment, a 21st-century ecosystem service. TakeAirLabs presents the Indoor Biosphere as a systemic solution to the challenges of the indoor environment. We go into detail about how climate change is interlocked with global pandemics and the effect it has on our built environment.

The purpose that we use such a biological word, the Biosphere, is that we believe that the microbial design and technological performance of the indoor environment are the driving forces for human health in the built environment. It is the technological advancement that brought us here. It is the microbial evolution that made us who we are. The air we breathe as the next frontier for innovation.

Looking at the indoor environment as a Biosphere asserts that a high-performance building is breathing, it can get sick, but it can also become stronger, more resilient. We acknowledge that the indoor environment should be adaptable and able to respond to disasters both natural and man-made, be it a global health pandemic or the incorrect implementation of environmental services. By connecting hospitality and sustainability a strategy is presented for decades to come.

The Biosphere is a radical paradigm shift where we connect all living mechanisms with the environment in which it is hosted. The air we breathe not as a statistic neutral force, but as a driving positive force in preparation for the nascent next generation health society.

A systemic approach to go beyond IAQ and deliver true change. Reconnect four key stewards that drive health where the indoor environment is a social-ecological catalyst. The Ecological Biosphere is adaptive, dynamic, circular, and growing, the social Biosphere is responsive, inclusive, anticipates and reflects.

Update 03/08/2021:

Sea-Aeration selected for presenting at Healthy Buildings 2021-America.

It is with a great sense of achievement we announce being officially selected for the Healthy Buildings America 2021 conference in Hawaii, Honolulu.

TAL will be representing Belgium’s finest innovations in the field of BioTech air management. A nature-based solution for indoor climates to create a more resilient environment in protecting our health. The first sustainable and circular approach in reducing indoor respiratory infections for buildings.

Our abstract: “Marine red sea algae in combatting indoor respiratory infections: A catch and kill exposure reduction strategy”. is being presented at the conference from 9 - 11 November 2021

Update 03/05/2021

Higher capturing capacity with limited pressure loss for Sea-Aeration technology

In collaboration with the University of Genova, we developed a digital twin of our system that further sharpens our numbers regarding particle uptake and pressure loss. The conclusion here was that there is a pressure loss of 7.2 Pa and 87.8% of particles will be captured by our system.

Due to ongoing research, we reached an improvement where we capture 92% of particles and 99% of particle mass. With only an 8.2 Pa increase in pressure drop resulting in a total of 15.4 Pa. pressure loss in our current set-up. Our research will continue to obtain even higher filtration capabilities with a limited increase of pressure loss.

Update 26/03/2021

Results lab-scale and large-scale Sea-Aeration testing.

Regarding the R&D working paper released on November 2020: Aeration by Sea used in combatting airborne viruses in ventilation systems. We are enthusiastic to share our final report conclusions. In relation to these test results, a second R&D position will be released in light of these findings.

The main achievements, based on the experiments with the lab-scale and the large-scale ventilation systems can be summarized as:

  • Optimized positioning of the virus catcher in the ventilation tube without causing important obstructions of airflow;
  • Experimental demonstration of a high phage-capturing capacity of the treated filter: up to 94 % (phage) decrease;
  • Demonstration of fast die-off of captured phages on the treated filters: log 3 PFU decrease;
  • Demonstration of important die-off of captured phages on the filters: up to 60 % decrease within 1 hour of air recirculation and over 99 % overnight.
  • No important detachment of the captured phages from the treated filters;
  • No bacterial growth on the filter, during a period of 2 months (static tests), and no Legionella growth on a treated filter that was incubated in the air duct for one month;
  • Long-lasting phage capturing capacity of pretreated filter (1-2 weeks; longer-term experiments ongoing);
  • The developed formulation can be sprayed at regular intervals for the reactivation of filter properties.

The first proof of concept is produced and being actively tested at the WTF site by Revive in Ghent Belgium.


TAL Statement 10/02/2021

Opportunities in times of crisis, linking Covid-19 solutions to our SDGs

A year where the world became aware of the most ordinary and common element on earth, also the most challenging: the air we breathe. Some people may not suspect it, our sustainable development goals and 2030 Climate Target Plan share a strong link with our indoor air quality. Today a global health crisis has urged us to go into overdrive. As we are trying to create healthy (virus-free) indoor environments, we must acknowledge the mentality shift that will shape future goals. The call for ambitious policy and better indoor air quality is gaining momentum, our sustainable goals and the IAQ are more than ever interlinked. The world is forced to act now, TAL is giving its long-term commitment towards biobased sustainable solutions and standards. It’s the vision of safe ecological limits and promoting good practices that make the bioeconomy the preffered partner. TAL interlinks the land and marine ecosystems and the services they provide. Biological air treatments for indoor spaces with a common vision of a sustainable future

"As we take action now in combatting a global pandemic, we have the momentum and opportunity in contributing to our 2030 climate plans and global SDGs"

Air pollution has been linked with severe outbreaks of SARS and SARS-COV19 in cities throughout China, Italy and the United States. The accessory in these outbreaks is among us, in the rooms and buildings we live and work. CO2 and PM2.5 levels are known of effecting a wide range of health issues and are in strong correlation with the quality of our indoor air. If we address these variables and physically remove airborne particles, we have a condition that is favourable. If we want an enhanced and healthy environment enabling good health and well-being, we need the help of our natural microbiomes. The microbiome is a rising star in the bioeconomy.

TAL Statement 09/12/2020

Healthier offices and schools for healthier economies.

Looking back a few years in time we could say we were just not ready. From Energy Performances certificates to Indoor Environment Quality (IEQ), We saw some ambitious policy on an EU level. Today we know it is not enough. These programs nevertheless paved the way for innovation and progress that benefited the European citizen and its economy. In this statement, we argue that the time is now to revive the discussion about IEQ, starting with our most crucial aspect, the air we breathe.


As several national governments (Germany, Belgium, Netherlands) due to health concerns are open to investing in public and private buildings, and better ventilation practices concerning air quality. And companies are trying to figure out how to get people back inside after a prolonged stay at home. We fully support new policy and regulations on a member state level. As the focus for many will shift on what a healthy IEQ must be. We must not miss the same boat as we did in 2018. As the worst students in the class may not feel the need to implement new regulations, the impact on the daily lives of EU citizen is evident with more than 417.000 premature deaths in 2017 according to the EEA.
Support from the EU towards public and private building owners investing in IEQ could create a robust basis for future policies. Schools and offices make the perfect test case, as we spend an enormous time of our lives inside these buildings, we argue that the return on investment has significant potential. Recent news marked an improvement in Europe’s air quality over the past decades. We must continue this path and demand the same for our indoor habitats.

​As IAQ certificates would not solve the whole IEQ issue, we believe that creating awareness can become a driving force for the renovation sector in its totality. Not only creating benefits for the EU citizen in terms of job employment, health, economic growth and much-needed stress relieve for social healthcare systems. But also, for corporate Europe in creating offices where economic interests and health go hand in hand.

The next step after traditional filtration techniques: Bioremediation of our indoor air quality

The importance of our Indoor Air Quality (IAQ) will be a trending topic for the years to come. The recent crisis showed us how vulnerable we are inside our offices and buildings. TAL welcomes the broader discussion where we distance ourselves from conventional and traditional thinking and look for ambitious solutions today.​

When policymakers, companies or governments talk about physically combatting Sars-Cov2 the focal point commits towards traditional technologies such as ionization, HEPA filters and UV light solutions. The third route of infection for all pathogens is indeed the air we breathe, but it is also the most difficult to manage. As this discussion has a strong core of relevance, we emphasize that a broader discussion could benefit the issue of what healthy IAQ is. Cleaning, disinfecting or sterilizing are considered today as the only logical action to make. It is the opinion of TAL that this is only the first. As with the treatment of soil and water removing impurities and pollutants, a sterile condition is nor possible or favourable. Many of the traditional technologies today promise just that.

By trying to create what is a theoretical approach of a sterile environment, we give room to dominant pathogens to grow and become the dominant species (competitive exclusion). As traditional filtration systems have their downsides and sometimes even adverse health effects, a mitigating action is essential in creating a balanced indoor air environment, where healthy bacteria and archaea thrive. Bioremediation of the IAQ poses as the logical addition to an already effective ventilation system. To make the general public aware of clean and bio-remediated air, we bring back the trust to go back inside and live, work and breath in healthy habitat optimized for human consumption.
