Transforming Food Waste into Delectable Treats

Kuradashi, a company committed to reducing food waste through innovative initiatives, has recently announced the launch of its second wave of products under the unique sweet treats brand, GREEN DOLCE. This exciting new range will be available starting October 1, 2025, featuring four types of sweets made from byproducts of dried sweet potatoes sourced from Ibaraki Prefecture. Known for producing approximately 90% of Japan's dried sweet potatoes, Ibaraki generates around 2,000 tons of sweet potato byproducts annually, often discarded in the production process. By utilizing these materials, Kuradashi aims to create a sustainable solution to suppress food waste while offering delicious alternatives.

Addressing Hidden Food Waste

Kuradashi has established a mission to be a Social Good Company, focusing on the critical goal of significantly reducing food waste across Japan. The significant production of dried sweet potatoes in Ibaraki often leads to the cutting away of areas not meeting aesthetic standards, discarding about 40% to 50% of the total sweet potato. The immense financial burden associated with disposing of these byproducts contributes to a growing environmental challenge, leading to factors like foul odors and pest outbreaks in the region.

With this initiative in mind, Kuradashi is stepping in to turn discarded sweet potato byproducts into a delicious sweet treat. The new GREEN DOLCE range will showcase the sweet and fragrant essence of these ingredients, aiming not only to delight palates but to educate consumers on the pressing issue of food waste, especially those edible materials that often go unnoticed.

Exceptional Sweets from Exceptional Ingredients

GREEN DOLCE stands out for its commitment to crafting sweets that are both sustainable and exquisite. This upcoming collection has been developed by skilled pastry chefs with prior recognition at international competitions, ensuring that each product embodies an innovative approach to traditional sweets. Following the success of the first product line, which featured baked goods using sake lees and wine pomace, the second installment promises to further enhance awareness around underutilized ingredients and their potential deliciousness.

Starting October 1, sweets made from the byproducts of Nikko Foods, renowned for their premium sweet potatoes, will be available through Kuradashi's online platform. Additionally, a partnership with AU PAY MARKET will expand accessibility, allowing more customers to experience these unique treats.

Uniquely Crafted with Care

The four types of sweets aim to balance flavor and sustainability, highlighting the natural sweetness and rich flavor profiles of the sweet potato byproduct. Feedback from the previous product line indicated a surprising reception to flavors derived from unconventional ingredients, prompting praise for their taste and quality.

One contributing chef, Kohji Kato from Constellation., expressed delight in developing sweets from these often discarded sources, believing this method fosters a cycle of sustainability through enjoyable food experiences. Similarly, Keita Koishimizu of MOKA CHOCOLATE has worked diligently to ensure that these once discarded materials become stars in their culinary creations, contributing to a more sustainable future.

A Commitment to Sustainable Practices

Kuradashi's efforts to alleviate food waste do not stop at delicious sweets. Alongside launching GREEN DOLCE, they have opened a new business line aimed at supplying kitchens across Tokyo with their sweet potato residue paste, broadening the reach and accessibility of underutilized ingredients. This initiative will help boost awareness of sustainable culinary practices while showcasing creative ways to incorporate such materials into everyday menus.

In essence, Kuradashi's model encapsulates a progressive move towards achieving sustainability while also engaging consumers in the broader conversation about food waste management. By combining commerce with creative culinary practices, they are actively contributing to a more sustainable society.
