  • Infrastructure

Through innovation and extensive research, we at GreenBubble, have inherited the vast culture and agricultural know-how into our system. We have created our process by taking effective and proven technology from age-old agricultural practices and improvising these practices using modern biotechnology. This has made our process and technology very reliable and economically viable. Through rigorous analysis of existing aspects of algae cultivation and the needs of an economic system, we have categorized a algae technology into the following fields:

  1.  Algae Strain
  2.  Algae Cultivation

We have made a significant leap in commercial algal technology and its application by evaluating the problems in these fields.

imageNatural Selection and Evolution (NSE)

THEORY OF EVOLUTION forms the basis for the selection of our algae strains. We make wild strains compete against each other and choose the ones which are most suitable for the conditions present in our system. The algae selected are then evolved to adapt and fit into our system. The end product of our NSE process is an algae strain which grows very fast(doubles every 4 hours) and is extremely robust. An effective algae selection process forms a very strong foundation for our algae cultivation system.

Heterotrophic and Autotrophic Algae Polyculture

Unity is strength and division is weakness. It is better to have multiple algae species working together to defend against a multitude of enemies rather than a single specie. We grow different species of algae which help each other and keep unwanted algae out of our system.
In a typical GreenBubble system a culture medium consists of algae which grow both in the morning and in the night, among which few grow on sunlight and others on waste sugars. So in 24 hours we get the maximum biomass.

The realization that microbial algae can be controlled most effectively using microbes has helped in devising the BBCS mechanism The BBCS mechanism is used by us to guard and assist our algae culture. In BBCS mechanism we select microbes that are predators of wild algae, these microbes weed out wild algae acting as guardians to our algae cultures. In addition to this we have discovered various microbe inducers and aquatic creature which help ward of pests and assist algae growth.

Agro based waste nutrition

Agriculture is the source of nutrition for humans and domesticated animals. The same can be used as an effective source of nutrition for algae. Lower costs along with three other prominent facts have given us a strong motivation to choose agricultural byproducts and waste as input for our systems. The facts are:
  •  It is a widely accepted fact in agriculture that organic fertilizers and bio based pest control systems are superior to conventional synthetic alternatives on various parameters.
  •  With depleting petroleum resources it has become inevitable that we find alternatives for fertilization.
  •  The abundant availability of the product along with the unsustainable way in which it is currently being used or disposed off.

Reduce, Reuse, Recycle has been deeply etched into our engineering that even our harvesting adopts them. Using an ingenious proprietary process we are able to reuse a flocculant more than once, drastically reducing the amount of flocculant needed. The same ingenious process auto corrects the medium so that the water can be recycled into growing algae.
These 3 R's reduce, reuse, recycle have been the foundation for creating sustainable and cost effective systems, we believe it is the approach for the future to come.

Macro Biology assisted Agitation systems

One of the major costs of a modern algae production system is the agitation, we knew it that without a cost effective agitation system it would not be possible to scale. We looked at various traditions in China and India then compared them to how nature was doing it and we had our answer. We selected a few organisms which would grow along with the algae to keep it floating and well agitated. With our Macro Biology assisted agitation systems we have entered a new era of biotechnology based systems. Due to the combination of our HAASE system and the biological assisted system GreenBubble has a winning formula of cost effective production systems. The Macro Biology assisted Agitation systems has the following efficiency's that other agitations do not match:
  •  Micro level agitation.
  •  Clumping prevention.
  •  Micro level Nutrient Injection.
  •  Complete culture volume utilization

imageHybrid ad-hoc algae scale easy systems (HAASE)

With experience in cultivating in open ponds, Race Ways and Photo Bio-reactors, we have come to realize that we can combine the advantages of these into a single system. This realization has led us to create HAASE. Our HAASE system has individual pods which are grouped into various ad-hoc groups. Each Ad-Hoc group has individual pods which interact within the group for sharing nutrients, harvesting and diagnosis.
HAASE is a designed to provide:
  •  A layer of security against contamination.
  •  Preventing culture crash propagation.
  •  Efficient nutrient distribution.
  •  Efficient nutrient utilization.
  •  Highly effective agitation.

Low cost and reliable design
To create a positive and lasting impact in sustainability and environment, we had to include the consumables market among our target markets. For any industry to enter the consumable market the costs have to be reduced to a bare minimum. Among the major barriers in algae for making it low cost was the capital cost, our goal was to reduce it to a low, that was unheard of in the algae industry. With huge experience in structural engineering and low cost buildings, we were able to reduce the cost to a small factor to that of a open pond, which is the current lowest cost for set-up.
Expertise in the domains of low cost housing, structural engineering of high end machines and material science, has helped us design a system that is not only low cost but also very robust. Using ingenious methodologies we have been able to enhance the life term of many commonly use materials, letting us use it for a much longer time than they were designed for. The extension of the life has let us provide long lasting, robust and cost effective structures to cultivate the algae.
