Malt Trub
Project Statement:•Malt trub processing in the treatment plant costs $32 per 1,000 gallons.
•Malt trub has an elevated organic load which, when treated,produces strong odors.
•The company produces about 5,000 gallons average per week.
•Which costs approximately $8,300 per year.

Objective of the Project:
www.cerveceradepr.com
• Develop a viable solution to lower the costs of processing the malt trub.
• A meeting with cattle ranchers was held in order to come up with the idea of preparing a mixture of industrial and poultry waste to prepare cattle food.
• Spent Grain (SG)• Malt Trub (MT)• Chicken Poultry (CP)• Spent Grain + Chicken Poultry 1:1, 1:4• Malt Trub + Chicken Poultry 1:1• Spent Grain + Malt Trub + Chicken Poultry 1:1:1• Spent Grain + Malt Trub 1:1, 3:1, 1:2

Final Mixture Selection:
• Suggested by Agro. Arias:– Spent Grain, Malt Trub, and Chicken Poultry 1:1:1 for beef cattle.– Spent Grain alone for dairy cows.
• We determined by data analysis that the best sample is Spent Grain, Malt Trub 3:1

• Cheaper option for cattle feeding purposes.• High incomes.• Analyze other spent grain: malt trub: chicken manure
proportions.• Establish sample analyses based on swine nutritional
requirements.
