Japanese Firms Pioneering Creative Food Upcycling Tech

As the world's environmental consciousness expands, the practice of upcycling food, the creative re-use of discarded food products, is gaining substantial traction in Japan. This innovative approach not only reduces waste but also presents fresh opportunities for culinary creations and other applications.

One remarkable example of this movement is the transformation of cabbage cores – the tough inner part of cabbages that is often discarded. Partnering with the Co-Op Deli Consumers’ Co-operative Union based in Saitama, Kewpie Group has ingeniously repurposed these cores to craft delectable soup dishes like minestrone and potage. These items, known for their coarse texture and distinctive sweetness, are made available through a convenient home delivery service exclusively for registered members. Approximately seven tons of cabbage cores are projected to be utilized annually, significantly curtailing unnecessary waste.

Despite traditionally being relegated to the trash bin due to their fibrous and firm nature, cabbage cores boast surprising attributes. Constituting roughly 10% of a cabbage's total weight, they harbor a natural sweetness and are rich in dietary fiber, making them ideal candidates for inclusion in stewed cuisines. Toshiyuki Uechi from the Vegetable Innovation Department at Kewpie Corp.’s Institute of Food Creation attested, "Customers resonate with our environmentally conscious approach."

Expanding the horizon of upcycling, companies like Oisix ra daichi Inc. have been actively pioneering this concept since 2021. An illustrative endeavor is their creation of arare rice crackers (a type of bite-sized Japanese cracker made from glutinous rice and flavored with soy sauce), ingeniously concocted from coffee dregs salvaged from Pronto Corp.'s coffee shops. Collaborating with Choya Umeshu Co., Oisix ra daichi ventured into transforming leftover ume Japanese apricots, used in ume brandy production, into dried fruits. The company is striving to amass over $13 million in sales from upcycled food products by fiscal 2024.

The upcycling movement transcends the culinary realm, witnessing creative applications beyond edible products. In a striking synergy, Ito En, Ltd. and Mizuno Corp. joined forces in 2018 to engineer artificial turf using discarded tea leaves sourced from Ito En's Oi Ocha tea beverage manufacturing process. Installed on a soccer field at Teikyo Nagaoka High School in Niigata Prefecture, this turf outperformed conventional black rubber chips in heat reduction. By blending used tea leaves from the equivalent of 430,000 plastic bottles of Oi Ocha Tea (525 milliliters) with resin, a novel and efficient turf material emerged.

Moreover, Meiji Co. unveiled a creative upcycling innovation in June – employing finely ground cacao bean husks as a molding material for crafting small containers and vases. These products not only offer utility but also emanate the delightful aroma of chocolate, enhancing the sensory experience. Katsunari Matsuda, President of Meiji, emphasized, "This initiative benefits both our consumers and the cacao industry."

It's noteworthy that discarded tea leaves and coffee grounds, although inedible and outside the purview of "food loss" according to the Agriculture, Forestry, and Fisheries Ministry, are becoming key components in the push to maximize resource utilization. This movement aligns with the ethos of もったいない "mottainai," a concept urging the reduction, reuse, and recycling of resources. As per the market research firm Global Information, the global upcycled food product market is anticipated to burgeon at an annual rate exceeding 6.2% until 2029.

Tomohiro Ishikawa, a senior researcher at the Distribution Economics Institute of Japan, remarked, "This upcycling trend is congruent with consumers' growing penchant for value-added products." As Japan's upcycling movement continues to evolve, it not only addresses the challenge of food waste but also ushers in a new era of resourceful innovation that resonates with both environmental consciousness and culinary delight.

With the boundaries of innovation constantly pushing the envelope, will this emerging era of upcycling redefine our relationship with waste and consumption? Do you find yourself captivated by the symphony of sustainability and imagination, intrigued by the harmonious blend of practicality and pleasure? Will other countries in the future advocate for change, embracing the mottainai spirit, and savoring the possibilities of this new kind of recycling?
