Valorization of brewer's spent grain for sustainable food packaging

Zeinab Qazanfarzadeh et al.

Summary: The accumulation of petroleum-based plastics necessitates the search for biodegradable packaging materials. Brewer's spent grain, a by-product of beer production in Europe, has potential value in the food packaging sector due to its high biomaterial content and large annual generation. This study comprehensively examines the extraction of high-value products from brewer's spent grain using various biorefinery techniques and evaluates the potential of biodegradable films and coatings derived from brewer's spent grain for food packaging. Techno-economic factors, environmental impacts, and challenges are also assessed. The best biorefinery system requires a balance between extraction efficiency, energy consumption, environmental impact, upscaling feasibility, and operating cost. Cellulose, lignin, xylitol, and arabinoxylan are recommended as promising components for food packaging applications.
