Jams and marmalades have always been a way to preserve fruit, making them a natural fit for a grocer like Carrefour seeking to rescue (over)ripe, damaged or otherwise unsellable produce. In the past — since chucking is usually cheaper than processing — supermarkets tipped unsold products into dumpsters without a second thought. But conscious consumers and persistent activists have provoked a newfound, collective sense of responsibility for food waste, and that mindset shift is paving the way for creative solutions that aren't based solely on financial calculations.
