At Kaffe Bueno, we are all about giving life back to what most consider waste; we recycle used coffee grounds, or technically known as Spent Coffee Grounds (SCG) to extract healthy and high value components. In short, SCG is the coffee grounds remaining after your brew. SCG is a by-product with fine particle size and high organic load. Its chemical composition is based on cellulose, hemicelluloses, proteins, fat, polyphenols, minerals and different products formed by the Maillard reaction during the roasting process, such as melanoidins. These compounds have shown several biological activities, including antiproliferative, antioxidants, and antimicrobial effects (Mariotti-Celis et al. 2017).
