“…However, only a very small database is used here and no concrete application of the method is described. Other work deals with brewery waste and wastewater recovery using modeling and simulation [22][23][24]. Special attention must be paid to modeling using petri nets or so-called reference nets and simulation based on them.…”

The global brewing industry is facing enormous environmental challenges and is urgently required to produce sustainably and efficiently. The rising costs of energy and electricity are forcing small and medium-sized breweries in particular, which are confronted with barriers such as lack of capital and know-how, to make substantial changes. This article presents an extended approach to prognose the energy and media demand for batch-oriented production of a brewery. Therefore, based on a modeling editor as well as a standardized data structure and an approach to determine the simulation-relevant parameters, a solution for fast and easy model generation was developed. Extensive measurement recordings within a brewhouse were performed to create a comprehensive model with recipe-specific parameters and detailed production plans. A simulation model can be generated automatically from a configuration file in a simulation environment that has been extended to include the mapping of batch-oriented operation. A validation is presented and a maximum deviation of the electrical and thermal energy demand of 1–2% is achieved. In combination with a preliminary work, the holistic simulation of the complex combined production of batch-oriented and discrete operation within the brewery is presented and allows comprehensive analysis as well as optimization towards sustainable production.

“…Atualmente, o bagaço de malte é destinado principalmente para uso na ração animal, ou ainda para aterros (Bolwig et al, 2019). Portanto, recuperar energia a partir do aproveitamento do bagaço de malte revela uma oportunidade de beneficiamento econômico, aliado a destinação adequada do mesmo (Siqueiros et al, 2019).…”

Objetivo: Investigar a produção de biogás a partir da digestão anaeróbia do bagaço de malte. Métodos: O processo de digestão anaeróbia foi avaliado sob diferentes condições operacionais de temperatura (30, 40 e 50 °C) e proporção inóculo/substrato (20/60, 40/40 e 30/50, g/g), e, também, utilizando bagaço de malte bruto e com pré-tratamento (moagem e hidrólise ácida). Resultados: A maior produção de biogás foi alcançada na condição experimental de 50ºC e proporção inóculo/substrato de 40/40 (g/g), utilizando bagaço de malte sem pré-tratamento, resultando na produção de 535 mL e rendimento de 13,38 mL/ gsubstrato. Nesta condição, a produção de biogás foi avaliada utilizando bagaço de malte com tratamento físico (moagem) e químico (hidrólise ácida). Nenhum dos pré-tratamentos investigados resultaram em melhor produção e rendimento de biogás quando comparado aos resultados utilizando bagaço de malte bruto. Neste trabalho também foi determinado o custo de produção em escala laboratorial para as condições avaliadas. O ensaio utilizando bagaço de malte com pré-tratamento físico resultou no maior custo (R$ 25,15) e o ensaio utilizando bagaço de malte sem pré-tratamento no menor custo (R$ 17,87). Conclusão:Portanto, conclui-se que o bagaço de malte na forma bruta destacou-se positivamente em comparação ao bagaço de malte pré-tratado, tanto em termos de produção e rendimento de biogás quanto em termos de custo.

“…With heterogeneous characteristics, including the skin, pericarp, endosperm of the malted barley grain (5), it accounts for about 85% of byproducts, consisting of lignin, cellulose and non-cellulosic polysaccharides together with fatty acids and minerals (6)(7)(8). Much research has been performed to explore the industrial and technological applications of spent grain including polymers (9), biofuels (10,11), fish food (12), enzymes (13), energy (14,15) and polysaccharides (16).…”

Brewery spent grain: a potential biosorbent for hexavalent chromium

2021

Spent grain is a solid waste from the brewery process which is used as feed for ruminants or as organic fertiliser. Due to the large scale generation of spent grain, new technological and industrial applications are being developed. In this work, spent grain was modified by chemical treatments for use in the biosorption of hexavalent chromium. For spent grain treated with acid, alkali, petroleum ether and hydrogen peroxide, the amount of hexavalent chromium removed was respectively 97, 21, 0.9 and 0.5%. The kinetic data of spent grain biosorbent treated with acid, untreated and treated with alkali were applied to pseudo‐first order, pseudo‐second order and intraparticle diffusion models. The pseudo‐second order model showed the best fit to the kinetic data, indicating chemisorption in the biosorption processes. The effects of pH and biosorbent concentration were analysed for spent grain treated with acid. The optimum values for pH and concentration of the biosorbent were pH 2 and 2 g/L.
