White Biotechnology: Unlocking Sustainable And Greener Solutions Through Bioprocesses

White Biotechnology

White biotechnology, also known as industrial biotechnology, refers to the application of biotechnological processes and techniques to industrial processes for sustainable manufacturing. It harnesses microorganisms like bacteria, fungi, and algae and uses them to drive chemical and biological processes that can enable greener and more sustainable production.

Applications of Industrial biotechnology

The main applications of industrial biotechnology include production of biofuels, bioplastics, bio-based chemicals, food/feed additives and more through fermentation and other bioprocesses. Let us look at some of the important applications in detail:

Biofuels Production

One of the major applications of White Biotechnology  is in the production of biofuels like bioethanol and biodiesel as alternatives to fossil fuels. Through fermentation, microbes like yeast are able to efficiently convert various biomass feedstocks like sugarcane, corn, cellulosic materials into simple sugars and then bioethanol. Other advanced biofuel pathways are also being developed through metabolic engineering of microbes. This helps reduce dependence on fossil fuels and lower carbon emissions.

Bioplastics Manufacture

Through fermentation processes, companies are able to produce biodegradable plastics or bioplastics from renewable feedstock instead of petroleum. For example, companies produce polyhydroxyalkanoates (PHAs) which are a family of biodegradable thermoplastics using fermentation of glucose or lipids by microbes like Cupriavidus necator. These bioplastics have applications as alternatives to traditional plastics in various sectors.

Bio-based Chemicals Production

White biotech enables efficient, sustainable manufacturing of various building block chemicals and materials from renewable resources through fermentation. For example, companies produce lactic acid, 1,3-propanediol, succinic acid, glucaric acid and more using engineered microbes for applications as solvents, polymers, additives. This helps cut down dependence on traditional petrochemical routes.

Food and Feed Additives

White biotechnology also finds applications in the production of various food and feed additives through fermentation. For instance, companies produce amino acids, vitamins, organic acids and various other feed additives by growing specific microbes and help enhance nutrition of livestock and poultry. Such additives ensure quality and sustainability in food and feed production.

Waste Treatment and Bioremediation

Certain applications of industrial biotechnology involve utilizing microbes for treatment of industrial waste and bioremediation of contaminated soils and waters. Bioprocesses are used to degrade and breakdown toxic pollutants and convert them into less harmful by products with microbes. This provides eco-friendly solutions for waste treatment problems.

Advantages of Industrial biotechnology

Industrial biotechnology helps address sustainability challenges through industrial bioprocesses, providing numerous advantages over traditional production methods:

Renewable and Sustainable:
It relies on renewable biomass and agricultural waste as feedstocks rather than finite fossil resources. This makes production processes carbon-neutral and more sustainable.

Environment-friendly:
Bioprocesses generate fewer by products and wastes, especially greenhouse gases. They also enable waste treatment and remediation in an eco-friendly way.

Energy efficient:
Microbial conversions are often more energy efficient compared to physicochemical routes requiring high temperatures and pressures.

Versatility:
A single bioprocess or microbe can be engineered to produce various chemicals, replacing multiple traditional production steps. Metabolic pathways are also flexible.

Less Capital Intensive:
Once established, bioprocesses have lower fixed capital costs than petrochemical processes due to milder reaction conditions and flexibility of operations.

Regional availability:
Feedstocks used in bioprocesses like agricultural residues have regional availability reducing transportation costs compared to centralized petroleum operations.

Thus, through various industrial applications, White biotechnology is playing an important role in enabling transition to more renewable, efficient and greener manufacturing solutions globally. With advances in systems and synthetic biology, its potential is expected to grow further in the coming decades.

Challenges and Future Prospects
While industrial biotechnology shows huge promise for a more sustainable future, it is still a relatively nascent field compared to traditional chemical industry and faces certain challenges:

- High production costs: Despite process intensification, costs of producing chemicals through fermentation are still higher than traditional routes especially for bulk chemicals. This challenge needs to be addressed through advanced biocatalysts and process engineering.

- Limited substrate spectrum: Most bioprocesses currently rely on sucrose, starch or lignocellulosic substrates. A wider range of low-cost substrates need to be utilized for commercial scale production.

- Scale-up hurdles: Transitioning from lab-scale processes to large-scale industrial operations poses technical challenges around robustness, productivity and downstream processing that require focussed R&D.

- Unfavorable economics for some applications: For certain chemical products where demand is low and value is low, fermentation based routes may not be economically viable.

- Need for advanced biocatalysts: Development of more robust and efficient microbial cell factories and enzymes through systems and synthetic biology is key to overcoming economic bottlenecks.

Going forward, with continued progress in systems and process engineering, White biotechnology is expected to play an increasingly important role in industrial transformation. It will enable more localized, distributed manufacturing models and provide sustainable solutions across sectors once challenges around scale, yields and economics are addressed adequately through focused R&D. Moreover, advances like synthetic biology will allow designing new microbial cell factories and pathways to produce an even broader range of chemicals and materials. This will accelerate commercial use of industrial biotechnologyglobally for a greener future.
