The waste food upcycled into new products
The concept of turning food waste into new food products, known as upcycling, is gaining traction as an innovative approach to combat the growing problem of food waste and its associated greenhouse gas emissions. Food waste contributes nearly 8% of global greenhouse gas emissions, with a significant portion of this waste ending up in landfills where it releases methane, a potent greenhouse gas.
In Copenhagen, chef Rasmus Munk, who operates the Michelin-starred restaurant Alchemist, has taken upcycling to the next level at his lab, Spora. There, discarded food scraps like cocoa husks and rapeseed cakes are transformed into new culinary creations, such as chocolate and tacos. Munk’s mission is to create a more sustainable future by repurposing food waste into delicious, edible products.
The problem of food waste is enormous, with nearly 40% of all food produced in the U.S. going to waste each year. The U.S. Environmental Protection Agency and the Department of Agriculture have recognized the issue and released a National Strategy for Reducing Food Loss and Waste, aiming to halve food waste by 2030. Upcycling is seen as a promising solution to this problem.
The upcycled food market is growing rapidly, with the market valued at $53.7 billion in 2021 and expected to reach $97 billion by 2031. Companies around the world are finding innovative ways to repurpose food waste. For example, spent grain from beer production is being turned into bread, pasta, and supplements, while coffee grounds are being used to make products like gin, flour, and energy bars.
Start-ups and small companies are leading the charge in upcycling, but scaling up remains a challenge. Upcycling processes can be costly, and the higher prices of upcycled products can deter consumers. Experts argue that larger companies need to get involved, and policies should be implemented to make wasting food streams more expensive than reusing them.
The environmental benefits of upcycling are significant. By reducing the amount of food waste sent to landfills, upcycling helps decrease methane emissions. Additionally, repurposing food waste alleviates pressure on food supply chains, conserves resources, and provides nutritional benefits.
In Estonia, for example, a start-up called AIO is working on upcycling sawdust and other organic waste into palm oil and coconut oil alternatives, which have a lower environmental impact. Similarly, at Spora, Munk aims to bring upcycled food products to supermarket shelves within a year, pushing the industry to embrace sustainable practices.
While upcycling is still in its early stages, its potential to improve food systems and reduce waste is immense. For upcycled food to become mainstream, consumer awareness needs to grow, and the food industry must embrace this sustainable approach on a larger scale.
