Atık yönetimi, biracılık sektörü de dahil olmak üzere tüm gıda endüstrisi için çevre bileşenlerinin korunması, kirliliğin önlenmesi ve ekonomik üretim için kritik bir öneme sahiptir. Çevre kirliliği, dünya nüfusundaki artış ve buna bağlı olarak daha verimli üretim yöntemlerinin geliştirilmek zorunda olması gibi nedenlerle atık ve yan ürünlerin geri kazanılması ve bu atıklardan katma değeri yüksek ürünlerin üretilmesi zorunlu hale gelmektedir. Bira üreticileri, atıkların yönetimi için ülkeler tarafından yürürlüğe sokulan çevre ile ilgili yasal düzenlemelere uymak zorunda olup, bu konuda ciddi yatırımlar yapmaktadırlar. Bira sanayi için olumsuz bir maliyet unsuru olan organik yapıdaki bira sanayi atıkları, biyoteknolojik süreçler için ucuz maliyeti ve zengin kimyasal kompozisyonu ile gelecek vaat eden bir ham madde kaynağını oluşturmaktadır. Bu çalışmada, bira üretimi sonucunda ortaya çıkan çeşitli atık ve yan ürünler tanımlanmış ve bu atıklar ile yan ürünlerin biyoteknolojik yöntemlerle değerlendirilme olanakları incelenmiştir.

Anahtar Kelimeler
