“Hyperspectral imaging”—technology that allows someone to scan foods for imperfections, ripeness and contamination—will drastically cut the amount of waste in the food industry. Because photographs of produce can be used to determine problems, physical probing or complete destruction won’t be necessary. Thus, contaminated, unripe or imperfect foods can be spotted without ruining consumable ones—hopefully cutting back on our waste rate, which is at about 33% of all food. This technology has long been used by NASA and other big-budget agencies, but it’s becoming more affordable and widespread. Read more about the technology on CNBC.
