“…Yapılan çalışmalar, karbonhidrat, azot ve esansiyel vitamin içeriği sayesinde tortuların, fermantasyon süreçleri içinde karbon, azot ve besin maddesi kaynağı olarak değerlendirilebileceğini göstermiştir [14]. Bira tortusu; aktif karbon [47], adsorbent [48], metan [49], biyohidrojen [50], hayvan yemi [51], ksilitol [52], enzim [53] üretimi için ekonomik bir besin bileşeni olarak kullanılabilmektedir.…”

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.Waste management is a critical and important issue for the food industry related to the issues of environmental protection, pollution prevention and process economy. Utilization of waste and by-products for the production of high value-added products becomes compulsory due to economic and environmental issues. Since brewery industry generates large amounts of organic wastes, breweries make investments for the management of wastes according to the environmental regulations forced by the rules of the countries. Although brewery waste is a negative cost factor for brewery industry, its rich content of complex carbohydrates, nitrogen and minerals opens avenues to the production of biotechnological products such as biofuel, enzymes, organic acids and bioactive compounds. In this review, different types of brewery waste and by products are defined and alternative valorization methods and utilization strategies in biotechnological processes are explained.

“…There has been a small number of studies on the production of carbonaceous materials derived from beer waste, mainly by using only the lees waste of the production. Some of them reported the manufacture and characterization of the carbonaceous material or its use in a non‐energy‐related topic and other applications, even reporting its use in hydrogen storage or capacitors . In the present study, we have obtained, by a simple pyrolysis process, a dual‐porosity carbon derived from after‐boiling waste (ABW) and its use in cathodes of Li–S batteries.…”

The development of renewable energy sources requires the parallel development of sustainable energy storage systems because of its noncontinuous production. Even the most‐used battery on the planet, the lithium‐ion battery, is reaching its technological limit. In light of this, lithium–sulfur batteries have emerged as one of the most promising technologies to address this problem. The use of biomass to produce cathodes for these batteries addresses not only the aforementioned problem, but it also reduces the carbon footprint and gives added value to something normally considered waste. Here, the production, by simple and nonactivating pyrolysis, of a carbon material using the abundant “after‐boiling waste” derived from beer brewing is reported. After adding a high sulfur loading (70 %) to this biowaste‐derived carbon by the “melt diffusion” method, the sulfur–carbon composite is used as an effective cathode in Li–S batteries. The cathode shows excellent performance, reaching high capacity values with long‐term cyclability at high current—847 mAh g−1 at 1 C, 586 mAh g−1 at 2 C, and even 498 mAh g−1 at 5 C after 400 cycles—drastically reducing capacity loss to values approaching 0.01 % per cycle. This work demonstrates the possibility of obtaining low‐cost, highly sustainable cathodic materials for the design of advanced energy storage systems.

“…Over the past two decades, recycling industrial biowaste as precursor of low cost fabrication of activated carbon has been implemented to boost circular economy and develop, among other materials, electrode material for supercapacitors [22][23][24][25][26][27][28][29]. Recently, some authors have used residues from the beer extraction processes or brewer's spent grain (BSG) as a precursor material for obtaining activated carbon [30][31][32]. This type of biowaste, which has been generally used in the production of animal feed, has turned out to be good candidates for the development of electrode materials for EDLC performance in 0.1 M H 2 SO 4 electrolyte solution, showing high specific capacitance values in the range from 128 to 188 F/g [33].…”

‘In-Situ’ Preparation of Carbonaceous Conductive Composite Materials Based on PEDOT and Biowaste for Flexible Pseudocapacitor Application

Composite materials of poly(3,4-ethylenedioxythiophene) (PEDOT)/activated carbon (AC) were prepared by ‘in-situ’ polymerization and subsequently deposited by spray-coating onto a flexible electrolyte prepared in our laboratories. Two activated carbons were tested: a commercial activated carbon and a lab-made activated carbon from brewer’s spent grain (BSG). The porous and spongy structure of the composite increased the specific surface area, which helps to enhance the energy storage density. This procedure to develop conductive composite materials using AC prepared from biowaste has the potential to be implemented for the preparation of polymer-based conductive inks for further applications as electrodes in pseudocapacitors.
