Most of the food wasted in the process of farm to stomach is wasted and thrown into the ocean, and when food decomposes without oxygen it releases methane, a gas that is known to be 4x more effective than co2 for trapping heat. Because food is the largest expense for a catering or F&B operation, food waste is negatively impacting those businesses’ bottom line, explained Rachid Noujeim, CEO of Middle East, Sodexo International, a catering and facilities management company. Statistics have shown that almost 50 percent of food waste can be salvaged or avoided.
