Fermentation

Advantages of Fermentation:

• The raw materials used in the process are renewable resources
• Acids are obtained which can be used in the production of certain foods
• It allows the creation of ATP (energy) in the absence of oxygen
• It produces hydrogen 
• Fermentation plays a big role in acquiring the flavour of tea or wine

Disadvantages of Fermentation:

• The process takes a long time
• It produces alcohol that is not refined which creates a need for further processing
• a byproduct of fermentation (VOC) is highly toxic to humans

Advantages of INDUSTRIAL fermentation:

• It is very efficient and can produce a lot of alcohol in a shorter amount of time
• The product is more refined 
• The by-products of industrial fermentation can also be used in the production of consumer items because it breaks down and re-assembles biochemicals

Disadvantages of INDUSTRIAL fermentation:

• High levels of energy are needed in this type of fermentation
• Industrial fermentation uses resources that are non-renewable
