Pomace is the solid remains of fruits or vegetables after they have been processed for juice or oil. It typically consists of skins, seeds, and pulp, and is a byproduct of industries like winemaking, olive oil production, and fruit juice extraction. This leftover material can be repurposed in various ways, such as animal feed, compost, or even as a source of bioenergy. For example, in the case of grapes, the pomace can be used to create grape seed oil or as a natural fertilizer, contributing to sustainable practices in agriculture and food production.
