“…In one of the studies investigating biochar as an adsorbent, ground coffee was mixed in different proportions with a consortium of Spirogyra sp., Microspora, Cladophora sp., and Rhizoclonium microalgae, the mixture was pyrolyzed at 400 °C for 60 min, and it was reported that biochars were suitable for soil improvement and could be adsorbed in water treatment to remove some toxic organic and inorganic pollutants (Saiyud et al 2022). In another study, Sargassum cymosum algae biomass was converted to biochar at 800 °C and found suitable for use in acetaminophen adsorption (Pimentel-Almeida et al 2023). Sen et al (2023) investigated methylene blue adsorption.…”

In agriculture-producing countries, pruning waste is obtained from fruit-bearing trees during the fruit-growing process. The present study aims to determine the potential of biochar of pruning wastes, obtained as a result of agricultural activities that have economic value. To the best of the author’s knowledge, no study has been conducted in Turkey to make a regional estimation of the biochar potential of pruning wastes. Biochar produced from waste provides the advantage of use in various fields, such as soil remediation and water and wastewater treatment. In this study, data on the number of trees bearing fruit (almond, apple, apricot, cherry, peach, pear, plum, and sour cherry) from the Turkish Statistical Institute were used based on the equations specified. First, the amount of pruning waste, then the usable pruning waste, and finally their biochar potential were calculated. It was estimated that the apple tree had the highest total biochar potential (41.5 thousand tons/year). Regarding the regions, the highest biochar potential was in the Central Anatolia Region for the apple tree (19.3 thousand tons), followed by the Eastern Anatolia Region for the apricot tree (13.6 thousand tons). The total biochar potential of pruning wastes from fruit-bearing trees in Turkey was estimated at 175 thousand tons for the year 2021.

“…Thus, information about the characterization of BCs derived from this feedstock is scarce. Our literature review found only a study dealing with Sargassum cymosum beach-cast BC pyrolyzed at a single temperature of 800 • C for assessing the adsorption capacity of acetaminophen [21]; the BC of this single beach-cast species was characterized by several physicochemical methods, but elemental and proximate analyses were not performed. In general, the use of biochars from different feedstocks as a soil amendment has been studied for some years [22][23][24], but algal BCs have been less frequently utilized as soil ameliorants compared to lignocellulosic BCs.…”

Limited knowledge is available regarding biochar (BC) obtained from beach-cast seaweed, which needs to be characterized to better prospect its potential applications. Beach-cast seaweed BCs were produced at two temperatures (300 and 600 °C) and two residence times (1 and 3 h). First, an extensive characterization of feedstock and their derived BCs was performed. Then, an incubation experiment was conducted to investigate the potential of these BCs as ameliorants in two acidic soils, classified as Umbrisols. Proximate and elemental analyses suggested the presence of more stable C structures in BCs at 600 °C with a high C, fixed carbon (FC) and low H, O and volatile matter (VM); additionally, thermogravimetric graphics showed less weight loss. Some features from the raw material were present in biochars obtained at 300 °C but absent at 600 °C. Dissolved organic carbon was much lower in BCs pyrolyzed at 600 °C than at 300 °C, suggesting the higher aromaticity of the former, allowing more resistance to water extraction. The breakdown of proteinaceous soluble materials after pyrolysis was revealed by fluorescence. Residence time caused minor effects in biochar properties compared to temperature. The soil pH and macronutrient availability of the two studied soils increased after beach-cast seaweed biochar addition.

RESUMO O carvão ativado apresenta suma importância em processos de adsorção de estações de tratamento de efluentes. Nesse contexto, a comunidade acadêmica direciona esforços para a produção de adsorventes alternativos e de menor custo utilizando resíduos agroindustriais. De maneira especial, o bagaço de malte, um resíduo da indústria cervejeira, pode ser utilizado para a obtenção de carvão vegetal, o qual tem sido aplicado em escala de bancada na remoção de fármacos em sistemas aquosos, por causa do seu potencial de remoção. Logo, o presente estudo contribui com uma análise referente à viabilidade econômica da produção industrial desse carvão. Empregou-se uma análise com foco no valor presente líquido e na taxa interna de retorno, com base em literatura, a fim de determinar o preço mínimo de venda/kg de carvão, com hipóteses preestabelecidas. Uma análise da implantação de uma unidade de produção de carvão vegetal nas cervejarias (on site), assim como de uma empresa direcionada para a compra do bagaço e produção do carvão (off site), foi realizada, obtendo-se preço de venda on site de US$ 1,78/kg e de US$ 1,84/kg para off site, ambos confirmando a viabilidade econômica do projeto. Ademais, com uma produção de 108 toneladas de carvão vegetal por ano com o preço mínimo de venda de US$ 1,78, é possível pagar os custos, gerando retorno de 9%. Por fim, a produção em ambiente próprio (off site) se faz mais interessante economicamente, pois não é necessária a realização de um acordo com uma cervejaria, cuja produção ocorre conforme as suas premissas.
