What specific problem are you solving?

Indoor air pollution is a global problem. People are spending 80-95% of their lives indoors, where air quality is 4x-5x worse than outdoors. Indoor CO2 concentration levels have been shown to reach unhealthy levels in occupied meeting rooms and classrooms, even with existing mitigation technologies. 

In the United States, it affects millions of people in big and small cities. Specifically, Indoor air pollution is an issue that many people in the Atlanta area struggle with. Particulate matter can get trapped inside your home, leading to poor indoor air quality and an increased risk for allergens like asthma or even heart disease.  

The “State of the Air” report, released today by the American Lung Association, finds that Atlanta's rankings are improving for some of the most harmful and widespread types of air pollution: particle pollution and ozone. Unfortunately, Atlanta still has the fourth poorest air quality in the Southeast. But this problem affects bigger cities such as New York and Los Angeles on a much larger scale. These cities rank 75th and 48th respectively, amongst the cities with the worst air quality. Occupants in polluted households may experience health defects in buildings where CO2 is elevated. However, symptoms are usually due to the other air contaminants that also build up due to insufficient ventilation. At high levels, carbon dioxide itself can cause headaches, dizziness, nausea, and other symptoms.   

Furthermore, numerous studies over the years have found a direct correlation between high CO2 levels indoors (as the result of lack of fresh air) and high levels of mold, dust, bacteria, and viruses in the air. Effects of increased CO2 concentration levels include reduced cognitive performance and respiratory illnesses such as asthma and COPD. This is exacerbated by the climate crisis as HVAC systems are becoming essential, and buildings become better sealed.  Heating Ventilation and Air Conditioning (HVAC) systems account for 38% of a building’s energy consumption and 12% of global consumption.

To mitigate indoor air quality problems, current HVAC systems are designed to introduce a percentage of untreated outdoor air via an energy-inefficient process of dehumidification and temperature control. The climate crisis exacerbates the problem by creating a negative feedback cycle of the increased need for HVAC systems, driving increased energy expenditure, climate impacts from energy generation, and ultimately more harmful air quality.       

What is your solution?

VerdeTerra merges innovation by tapping into nature to address modern-day challenges. At the heart of our initiative lies a simple, yet profoundly impactful concept: leveraging the natural propensity of algae to purify our atmosphere whilst integrating our technology with HVAC systems to improve energy efficiency in the process. By cultivating these algae, we've devised a mechanism that not only combats the escalating levels of carbon dioxide—a principal culprit in the global warming crisis—but also gives back to the economy in the form of valuable by-products.

Our solution revolves around the cultivation of algae, which are tiny powerhouses capable of performing photosynthesis—the process of converting sunlight, water, and CO2 into oxygen and biomass. This not only cleans the air we breathe but also results in the production of biofuels, offering a sustainable alternative to fossil fuels; animal feed that supports our agricultural sector; and raw materials for creating biodegradable plastics, thereby promoting a circular economy.

Implementing this vision, we utilize a dual strategy. The first employs photobioreactors (PBRs), controlled environments that fine-tune factors critical to algal growth, such as light intensity, temperature, and nutrient supply, ensuring optimal conditions for photosynthesis and, consequently, CO2 absorption. 

Second, VerdeTerra’s novel technical design utilizes photobioreactors as air scrubbers with cyanobacteria to capture CO2 for air purification indoors. Utilizing nature’s most effective CO2 scrubber spirulina, that is 10-20x more effective at removing CO2 than any terrestrial plant. It will be the first CO2 air scrubber for HVAC systems. Offering full automation and only biomass collection service needed to keep cost and maintenance intervals in line with existing HVAC services. The system will be the first control system directly interfacing photobioreactors with HVAC systems to reduce energy consumption by subverting the demand on the outside air requirements.  

The technology underlying VerdeTerra's system is a blend of ecological insight and advanced engineering. Our open ponds are the result of sophisticated hydrodynamic modeling, optimizing the interplay of light and nutrients. The PBRs, state-of-the-art sensors, regulate environmental variables to maintain the perfect algal growing conditions. Once harvested, the algal biomass is processed through mechanical and chemical techniques, extracting its maximum potential.

But the innovation doesn't stop there. VerdeTerra is harnessing the power of data analytics and machine learning to push the boundaries of what's possible. By collating vast amounts of data on growth patterns and environmental factors, we deploy predictive models to enhance the efficiency of our systems, ensuring each algae system yields a bounty of biomass and captured CO2.

VerdeTerra's solution offers a path to not only mitigate the impacts of climate change but to stride toward a future where sustainable development is not just a concept, but a tangible reality. A promise of a cleaner, greener, and more sustainable tomorrow.
