Brewers Grain – turn waste to value

Dewatering Brewers Grain

Brewers grain has had a lot of press recently. Different companies are trying different uses to save this nutrient-rich by-product from going to waste. 

We used our equipment to dewater the spent grains, turning them into animal feed for cows. During the trial, the Vincent CP4 handled the dewatering, suited to the amount of grain this particular site produced. For a larger site, the CP10 would be a better fit. The results of this trial were very promising:

The process reduced the weight by 75% and the volume by over 50%, resulting in a product suitable as cow feed.

 

The market value for this product for use as animal feed is around £10 per tonne. 

To increase the value of the end product, the Bio-Processor could convert this into biomass fuel, as pictured above. This has an excellent calorific value of 4,681 kcal per kg. It rates higher than wood, wheat, and coffee, and ranks only below peat (see table below). 

 

By converting the product into a biomass fuel the value would increase to around £160 per tonne, depending where you are in the country. 

Either of these solutions would add value and use to a product that would otherwise be classified as waste.
