Before I dig into the controversy about coffee grounds in the garden, let’s examine their chemical makeup. Freshly ground coffee — the stuff that’s straight from the bag or the grinder and hasn’t been soaked or brewed — is acidic and high in nitrogen. Many gardeners say that adding ...
This work presents a way to use ethanol and spent coffee grounds (SCG) as feedstocks for biodiesel production to solve ethanol overproduction in Thailand and biodiesel feedstock shortage problems together. Waste coffee oil (SCGO) was ethanolic extracted from SCG; then, ethanol-SCGO mixture was tra...
Spent coffee groundsCadmiumSolar energyThis study evaluated the feasibility of employing spent coffee grounds (SCG) as adsorbent for removing Cd(II) from wastewater. The Taguchi experimental design was applied to determine the optimum adsorption condition. The controllable factors of the treatment ...
Spent coffee grounds (SCG), the residual materials obtained from the treatment of coffee powder with hot water, are the main coffee industry residues and founded to be rich hemicellulose, such as mannan and galactan. In this work, this material was treated under hot-compressed water condition at...
Stylianou, M.; Agapiou, A.; Omirou, M.; Vyrides, I.; Ioannides, I.M.; Maratheftis, G.; Fasoula, D. Converting environmental risks to benefits by using spent coffee grounds (SCG) as a valuable resource. Environ. Sci. Pollut. Res. 2018, 1-15. [CrossRef] [PubMed]...
spent coffee groundsA hydrometallurgical process is proposed in this paper to recover manganese from silicomanganese slag. The paper reports the digestion-leaching experiments and precipitation and electrowinning assays to recover Mn from this residue. Silicomanganese slag was first treated with sulfuric ...
However, by diverting spent coffee grounds from landfill and instead upcycling them for reuse in a circular economy, bio-bean’s Inficaf reduces waste and subsequent greenhouse gas emissions, not to mention driving behavior change and h...
It grounds the space and adds texture and dimension. To prevent the rug from moving, I found this rug on carpet pad to work the best. I didn’t want to hang anything above the crib, in the rare case it fell. So, I put up these two black IKEA frames on the wall beside the crib...
Soxhlet and accelerated solvent extraction, using propanol as a solvent, and supercritical CO2 extraction methods presented statistically insignificant differences in the crude oil yield obtained from spent coffee grounds. Supercritical CO2 extraction method was selected to recover the oil. The optimal ...
But with parts of Port-au-Prince now in ruins, tens of thousands of people displaced by the quake are camping directly in the bulwarks once associated with power and wealth, like Place St.-Pierre (across from the elegant Kinam Hotel) and the grounds of Prime Minister Jean-Max Bellerive’...
