Phenol adsorption by activated carbon produced from spent coffee grounds [PDF]
, 2011 The present work highlights the preparation of activated carbons (ACs) using spent coffee grounds, an agricultural residue, as carbon precursor and two different activating agents: water vapor (ACW) and K2CO3 (ACK).

Potential neuroprotective effect of spent coffee grounds extracts against neurodegeneration [PDF]
, 2022 Spent Coffee Grounds (SCG), a waste product of the coffee industry, are a renewable source of a wide range of nutraceutical compounds. Coffee wastes are particularly rich in phenols like phenolic acids such as chlorogenic, ellagic, caffeic, gallic, trans-

Hydrothermal Liquefaction of Coffee Silverskin and Spent Coffee Grounds : Bioenergy and Biochemical Potential [PDF]
Coffee roasting by-products represent a significant, underutilized side-stream globally. This study investigates hydrothermal liquefaction (HTL) as a method to convert these materials into hydrochar, water-rich light oil, and heavy oil.

The feeding value of spent coffee grounds for ruminants [PDF]
, 1977 For up to 26 days mature wethers were given a diet with 25% spent coffee grounds, a by-product of the instant-coffee industry. The coffee grounds had crude protein 10, crude fibre 44, ether extract 26, ash 0.75, moisture 8 and tannic acid 0.9%.
