Brew2Bio focuses on exploiting the organic fraction of municipal solid waste (e.g., coffee grounds and orange peels) to produce advanced biofuels (e.g., green diesel) and bio-based products suitable for adhesives used in composite wood products. The technologies under development can utilize various bio-based fractions of urban solid waste, thereby enabling the future implementation of sustainable processes. Brew2Bio employs bio-refinery principles to produce multiple value-added products, supporting the economic viability of biofuel production. By comparing thermochemical processes, bioprocesses, or combinations, the most sustainable method for producing green diesel is identified.

Objectives

• Develop an innovative bio-refinery for sustainable use of coffee waste and orange peels
• Optimize microbial lipid production using oleaginous yeasts fed by free sugars and cellulose/hemicellulose hydrolysates
• Optimize biofuel production
• Assess blends of plant-based and microbial oils for manufacturing bio-lubricants
• Investigate d-limonene in refining microbial oils and producing bio-lubricants
• Evaluate bioactive extracts as additives for bio-lubricant property enhancement
• Exploit protein/pectin fractions for making adhesives
