The winemaking industry process results in by-products called agro-industrial waste and is mainly composed of grape pomace. This by-product represents about 18% of the grape and results in waste disposal issues in the economic and environmental settings. The authors describe alternative green technologies for grape biomass valorization.

Patricia Joyce Pamela Zorro Mateus - Chemist and MSc. in Biochemistry from the National University of Colombia. I have academic experience in topics such as characterization of bacterial communities, population control by inhibition of quorum sensing between bacteria and currently, in valorization of wastes. In this field I have been working in biodegradation of xenobiotics from fungi and bacteria to find degradation products that could be reused, and I was also working with grape agro-industrial wastes to find natural oils, antioxidants, and biologically functional compounds. I have nine years of teaching experience; I currently work as a full-time chemistry professor at the Universidad Libre - Bogotá. In the past, I have also taught at the Jorge Tadeo Lozano University, Manuela Beltrán University and at the Open and Distance University (UNAD), in which I designed the Natural Chemical Reactions course (module, laboratory guide and virtual course) for the Chemistry career.

Siby Inés Garcés Polo - Chemical Engineering, B Sc., Msc and PhD from Universidad Pública de Navarra (Spain). Researcher and Research Chief of Faculty of Engineering in Universidad Libre Barranquilla. My experience is focused on gas adsorption processes for environment applications. In the last study, porous materials for CO2 capture and catalysts for dry reforming reaction were developed and studied, respectively. In academic terms, I currently teach Environmental Management and Chemistry. I am also interested in studying wastewater treatment, valorization of biomass and pyrolysis.
