From the point of view of the these different wastes, it was established that the C, N, P, and K contents in spent were 3.4, 3.0, 1.5, 7.6 times higher ...

is a popular and widely consumed beverage worldwide, with epidemiological showing reduced risk of cardiovascular disease, cancers and non-alcoholic fatty liver disease. However, few have investigated the health effects of the post-brewing product, spent (SCG), from either hot- or cold-brew . SCG from hot-brew improved metabolic ...

Although on heavy metal removal from water with spent have been carried out in the literature (Agwaramgbo et al. 2016;Akgün et al. 2013;Chavan et al. 2016;Kyzas et al. 2012 ...

eggshells was varied and depended on the type of eggshell (chicken, duck) and the date of eggshell collection (Table (Table3). 3). The study showed that spent (object SCG) contained more C, N, P, and K compared to the content in the chicken and duck eggshells (objects CES, DES).

Numerous also explored the extraction of value-added products from lipid fractions, such as oil (7-21% of total SCG dry mass) [20,27,28]. This oil has been used for biopolymer [29], biofuel [30], and sunscreen [31] production. Phenolic compounds have been extracted from oil and studied due to their antioxidant ...

Therefore, the study of its will be the basis to further improve and promote the , also the key to improve the flavor of . (2) Through a comprehensive and in-depth study of , comprehensive utilization will be an important link for further development and utilization of , such as flowers, leaves, , etc.

This study investigates the scientific basis for direct spent (SCG) and the influence of different: (i) plant pH and nitrogen preferences, (ii) soil types, and (iii) rates. We specifically consider impacts upon plant growth, soil hydrology and nitrogen transformation processes.

Spent (SCG) are produced in massive amounts throughout the world as a bio-residue from brewing. However, SCG are rich in carbohydrates, proteins, lipids, bioactive compounds and melanoidins, which are macromolecules with chelating properties. Additionally, SCG have showed in several fields such as biotechnology (bioethanol, volatile aromatic ...

majority of the produced spent are currently being inappropriately destined for landfills or to a form of energy recovery (e.g., incineration) as a refuse-derived fuel. The disposal of spent in landfills allows for its anaerobic degradation with consequent generation and emission of aggressive greenhouse gases such as ...

is a popular and widely consumed beverage worldwide, with epidemiological showing reduced risk of cardiovascular disease, cancers and non-alcoholic fatty liver disease. However, few have investigated the health effects of the post-brewing product, spent (SCG), from either hot- or cold-brew .

differences in the , being in the type or concentration of the compounds, are also evident in the spent [23]. On the above basis, spent can be a rich source of bioactive compounds of interest to the pharmaceutical, cosmetic, and food industries. The extraction of bioactive

Recent indicate that spent include its use to pro-duce construction materials [8], as soil organic amendment, to improve soil fertility as it increases N, P, and K content [11,12], as a source of polysaccharides for the preparation of an adsorbent for the removal of uranium in water [13].

is the world's second largest beverage only next to water. After consumption, spent (SCGs) are usually thrown away and eventually end up in landfills. In recent years, technologies and policies are actively under development to change this century old practice, and develop SCGs into value added energy and materials. In this paper, technologies and practices are ...

Spent (SCG) are a valuable biogenic waste diffused on a global scale, containing a significant amount of extractives. The aim of this study is to characterize the pyrolysis oil fractions, under various process conditions, targeting their as biofuels and source of valuable .

Spent (SCG) and silverskin (CS) represent a great pollution hazard if discharged into the environment. Taking this fact into account, the purpose of this study was to evaluate the , functional properties, and structural characteristics of these agro-industrial residues in order to identify the characteristics that allow their reutilization in ...

In sum, the most abundant families (furanic compounds, nitrogen compounds, esters, terpenoids) identified in the analyzed spent showed great to be used as raw material for in food (as an ingredient /or value-added components) /or in non-food products (e.g., pharmaceuticals, cosmetics, food packing), supporting its valorization based on ...

Many have investigated the pellet of some have found slightly lower heating values (18.8 MJ/kg 50, 19.6 MJ/kg 51) than that reported in this study while other report ...

results obtained in this work provide insight into the spent , allowing the identification and quantification of the bioactive compounds that remain in the matrix. Moreover, it was possible to conclude that this industry residue can be a rich source of numerous compounds with industrial interest.

By-products of fruit (Fig. 1) and bean processing can also be considered as functional ingredients for the food industry. husks, peel and pulp, comprising nearly 45% of the cherry, are the main by-products of agro-industry and can be a valuable material for several purposes, including caffeine and polyphenols extraction.

CSS indicates dietary fibre and antioxidant adjuncts for food industries as value adding . 2.3. Spent (SCG) The bean accounts for approximately 50% of the cherry dry weight and produces spent as the final by-product of the industry.

1. Introduction. Spent (SCG) are roasted and beans that were depleted of some of their water-soluble compounds. They are the solid residues obtained after beverage preparation and can be found in a variety of places including homes and commercial establishments that serve [].Disposal of SCG is quite a problem from an environmental point of view.
