P2P Microalgae Technology

Dr Tan and his team with patent

In recent years, scientists have become increasingly fascinated by a surprisingly useful botanical resource: microalgae. That’s why Dr. Weixing Tan and his team from Grande Prairie Regional College have spent over a decade developing an innovative, energy efficient way to mass produce microalgae. After years of research and development, Dr. Tan has created a prototype photobioreactor (PBR), a microalgae cultivation system that runs on energy from the sun’s rays. Thanks to patented sunlight attenuation, nutrient optimization technology and other world-class breakthroughs, it is the most productive solar-based PBR ever built. Tan’s PBR is now in the pre-commercialization phase of development, and we are looking for industry partners to move the project forward..

Why Microalgae?

Microalgae tubes

Microalgae are single-celled organisms that grow naturally in freshwater systems. Growing microalgae to combat CO2 emissions is a much more effective long-term strategy than tree planting, as microalgae is 10-100 times more efficient and does not use up vast areas of arable land. Most mass cultivation methods currently in use are expensive and energy-inefficient, making microalgae difficult to grow. However, microalgae have a variety of commercial and non-commercial uses:

How it Works

GPRC’s photobioreactor is IP-protected, scientifically demonstrated, and ready for pre-commercialization. This technology is unique particularly in four significant ways:

  1. Active Spatial Sunlight Attenuation (patented) One of the biggest challenges to mass cultivation systems for microalgae is achieving the correct balance of sunlight. If the microalgae are exposed to too much sunlight, much of the energy is unusable and wasted, and excessive sunlight will shut down and damage microalgae growth (photosaturation and photoinhibition). By limiting sunlight exposure without actually blocking it using Dr. Tan’s patented sunlight attenuation method, the PBR is able to make optimum use of solar energy. View our video simulation of the process.
  2. Growth Medium Optimization. P2P investigators have determined that a pH (proton) and nutrient balanced B-8 medium will achieve higher productivity at a lower cost compared to other media. Learn more here!
  3. Economical Harvesting System (patent-pending). This simple, energy-efficient and environmentally-friendly system substantially reduces production cost.
  4. Automated Long-term Water and Nutrient Recycling. This technique significantly reduces the use of water and nutrients and the operational cost.
