South Korea has almost zero food waste. Here's what the US can learn

After realizing the rate that which food gets thrown away at grocery stores due to approaching expiration dates, one man in Nigeria decided to do something about it. Oscar Ekponimo created a web-based app that lets grocery store retailers know if something is near expiration. Once notified, the retailers mark down the item; this allows non-governmental organizations to purchase and sell to people that are food insecure.

Luxury hotels collect and reuse food waste. The hotels audit their waste, then useful ways to give it new life—as compost, animal feed, or even biogas.

Bruce Friedrich, the Executive Director of The Good Food Institute in Washington, DC, thinks that we're wasting resources raising animals for food products. He thinks the answer is creating a product that doesn't replace meat, but rather competes with it.

Philabundance, a nonprofit organization aimed at fighting food insecurity, has a sustainable and creative solution. They launched a line of cheeses, known as Abundantly Good, and proceeds will help pay farmers to turn extra milk into cheese for people grappling with hunger. The process will engage ethically-minded consumers, support local farmers, make use of food waste, help the planet, and provide high-quality food to those who are food insecure. It’s a solution that benefits everyone involved.

Amager Bakke is a powerplant in Copenhagen that is designed to get residents of the city engaged in a conversation about where waste goes, all while burning up to 400,000 tons of waste a year, powering 60,000 homes, and heating 160,000 homes. In 2013 the local plant was redesigned to burn the city's waste and encourage interaction by building a ski slope atop the plant, a hiking trail, and an elevator that introduces education about waste management. Amager Bakke is still new and experimental, so its long-term success is still unclear, and it is not completely emission-free yet.

The Hannaford supermarket chain has achieved their goal of creating zero food waste. Over the past year, they diverted 65 million pounds of unsellable products to food banks, de-packing facilities, and anaerobic digestion facilities where it’s converted to energy. The grocery store is also making adjustments to how it purchases and sources food and how it’s displayed with the hopes of extending the food’s shelf life.

In 2020, a devastating explosion in Beirut that came from a warehouse released 800,000 and one million tons of construction and demolition waste and 20,000 tons of shattered glass into the city. The waste was being thrown into landfills. However, landfills are notoriously bad for the environment. Out of that rubble an idea was created; disposing waste sustainably. Rubble Mountains was created specifically to do this. They've been able to restore four quarries, use materials to create public amenities, and diverting up to 50 tons of demolition waste from landfills.

A community organization in Indiana called Cultivate "rescues" food from local caterers, hospitals, casinos, and businesses to then be packaged into take-home meals for students at Woodland Elementary School that come from food-insecure homes. Cultivate is in its second year of existence, has three staff and 400 volunteers, and hopes to expand beyond their pilot program to reach all 21 schools in the district.

The voluntary carbon market allows small-scale landowners to receive credits for reducing climate-changing emissions, which they can sell to corporations to offset their emissions. The carbon market has provided small landowners with other options to make money besides logging.

Solar-powered cold storage units help farmers in India to store their harvests during extreme heat instead of discarding their produce or trying to sell it quickly for cheap to avoid waste. The solar-powered option is significantly cheaper than typical electric cold storage, making it more accessible to small-scale farmers.
