Spent Coffee Ground Briquettes

2023
Coffee is regarded as highly consumed beverage throughout the world and has established a key spot in the world economy as an important commodity for trading. In general, it is produced by brewing its roasted and ground beans, which release aromatic coffee as well as produce an equivalent amount of spent coffee grounds (SCG) as waste.

Enzymatic Hydrolysis of Spent Coffee Ground

Applied Biochemistry and Biotechnology, 2013
Spent coffee ground (SCG) is the main residue generated during the production of instant coffee by thermal water extraction from roasted coffee beans. This waste is composed mainly of polysaccharides such as cellulose and galactomannans that are not solubilised during the extraction process, thus remaining as unextractable, insoluble solids.

The “COFFEE BIN” concept: centralized collection and torrefaction of spent coffee grounds

Environmental Science and Pollution Research, 2019
Spent coffee grounds are the moist solid residues of coffee brewing and in most cases, the disposal is done without any intermediate valorization actions for materials and energy recovery. State-of-the-art applications include extraction of the liquids and application of high-temperature pyrolysis.

Recovery of Natural Antioxidants from Spent Coffee Grounds

Journal of Agricultural and Food Chemistry, 2013
Spent coffee grounds (SCG) were extracted with an environmentally friendly procedure and analyzed to evaluate the recovery of relevant natural antioxidants for use as nutritional supplements, foods, or cosmetic additives. SCG were characterized in terms of their total phenolic content by the Folin-Ciocalteu procedure and antioxidant activity by the ...

Spent coffee ground torrefaction for waste remediation and valorization

Environmental Pollution, 2023
Spent coffee grounds (SCGs) are a noticeable waste that may cause environmental pollution problems if not treated appropriately. Torrefaction is a promising low-temperature carbonization technique to achieve waste remediation, recovery, and circular bioeconomy efficiently.

Valorization of spent coffee grounds: A review

Food and Bioproducts Processing, 2018
Abstract Spent coffee grounds (SCGs) arise as waste products through the production of instant coffee and coffee brewing. This work reviews the composition of SCGs, the methods used for the isolation of individual compounds present in SCGs, the ways of utilizing SCGs presented in the literature so far, including use of SCGs’ bioactive compounds ...

Spent coffee grounds: A potential commercial source of phytosterols

Food Chemistry, 2020
This study sought to determine the content of phytosterols (PS) in spent coffee grounds (SCG) to assess a novel industrial application of this coffee by-product as a commercial source of PS. Four PS were extracted and analyzed from 14 SCG samples from 12 countries.

Estrogen Receptor-Mediated Transcriptional Activities of Spent Coffee Grounds and Spent Coffee Grounds Compost, and Their Phenolic Acid Constituents

Journal of Agricultural and Food Chemistry, 2019
Spent coffee grounds (SCG) are the most abundant coffee byproduct and are generally discarded as waste. The horticultural use of SCG and SCG compost (SCGC) has become popular due to a growing interest in environmentally friendly measures for waste disposal.

Biotechnological conversion of spent coffee grounds into lactic acid

Letters in Applied Microbiology, 2018
This work investigates the potential bioconversion of spent coffee grounds (SCG) into lactic acid (LA). SCG were hydrolysed by a combination of dilute acid treatment and subsequent application of cellulase. The SCG hydrolysate contained a considerable amount of reducing sugars (9·02 ± 0·03 g l-1 , glucose; 26·49 ± 0·10 g l-1 galactose and 2·81 ± 0·07 g
