Take great advantages of brewer spent yeast

During the brewing process, yeast is added to initiate fermentation, converting sugar to alcohol and carbon dioxide (CO2). Before full maturation of the beer, the excess yeast is collected and can be re-used in the brewing process up to around six times. After this, it becomes brewer’s spent yeast (BSY) - the second biggest by-product of the brewing process (15% of total by-products generated). 

If we couldn’t take good advanrages of the beer spent yeast, it is a kind of bio-waste, but nowadays, there are some methods that turn the waste into food, beverages and feed, which has the potential of the following additional industrial applications:
yeast cell wall  as a probiotic in animal feed; 
partially autolysed yeast as a fermentation activator in the wine industry;
Bioactive peptides with health-stimulating and anti-oxidant properties in the food and cosmetics industries

Once the new process is fully operational, the project expects to:  Re-use 11 750 tonnes of BSY per year; Save 11.7 GWh of electricity, 38 903 m³ of water, 1 706 tonnes of glucose and 3 413 tonnes of CO2.

Therefore, Taking great advantages of brewer spent yeast is of great importance, which can not only reduce environmental waste, but also improve the economy value.
