Can IoT sensors reduce food waste? The inefficient supply chain is one of the main reasons for food waste. Almost one-third of global food production ends up wasted. Food loss can be the result of a number of circumstances, from lack of best practice on the farmer’s part to not enough space on the cold chain, but knowing where exactly the problems arise is not typically known. Greater implementation of IoT technologies could be the helping hand the food supply needs — providing a digital trail of the food’s journey.
