Superior Mesoporosity of Lipid‐Free Spent Coffee Ground Residues [PDF]

ChemSusChem, 2019
AbstractAs part of the biorefinery concept for spent coffee grounds (SCG), production of activated carbon (AC) was investigated from the degreased coffee grounds (DCG) left behind after oil extraction (primarily for biodiesel). The oils were extracted through conventional solvent extraction with GC/GC–MS confirming the oil was comparable to oils ...

Effect of fresh and composted spent coffee grounds on lettuce growth, photosynthetic pigments and mineral composition [PDF]

, 2014
The coffee industry has experienced a constant growth and, as a consequence, large amounts of residues are generated worldwide. One of the main coffee residues are spent coffee grounds (SCG), which are the solid residues obtained after preparation of the

Evaluation of Colombian Coffee Waste to Produce Antioxidant Extracts

BioResources, 2023
During coffee production, several types of waste such as pulp, mucilage, husk, parchment, coffee silver skin, and spent coffee grounds are generated. The amount of coffee waste and their environmental issues require effective valorization.

Impact of a Pretreatment Step on the Acidogenic Fermentation of Spent Coffee Grounds

Bioengineering, 2022
Acidogenic fermentation (AF) is often applied to wastes to produce short-chain organic acids (SCOAs)—molecules with applications in many industries. Spent coffee grounds (SCGs) are a residue from the coffee industry that is rich in carbohydrates, having the potential to be valorized by this process. However, given the recalcitrant nature of this waste,

THE POSSIBILITY OF DISPOSING OF SPENT COFFEE GROUND WITH ENERGY RECYCLING

Journal of Ecological Engineering, 2015
The current policy of waste management requires, above all, a gradual reduction of waste amount and, to a larger extent, forces us to seek new methods of waste disposal. Recycling the energy contained in biomass waste is a more and more universally applied method of thermal converting.
