## From Sugarcane Waste to Sustainable Denim: How Okinawa is Redefining a Traditional Crop
In the heart of Okinawa, where the sweet scent of sugarcane permeates the air, a unique story of innovation is unfolding. For centuries, sugarcane has been a vital part of Okinawan life, its cultivation deeply intertwined with the island’s economy and culture. Known locally as “Uji,” this resilient crop has thrived despite the challenges of drought, typhoons, and poor soil, providing sustenance and employment for generations.
However, the island’s sugarcane industry is facing a crossroads. The decreasing demand for sugar, coupled with the aging farmer population and the challenges of mechanization, has led to a decline in production. But amidst these challenges, a glimmer of hope has emerged – a sustainable denim brand called “SHIMA DENIM WORKS” that’s reimagining the very essence of sugarcane.
At the heart of this initiative lies bagasse, the fibrous waste product generated during sugarcane processing. For years, this by-product has been utilized for various purposes, including boiler fuel, livestock feed, and soil amendment. But a significant portion remained underutilized, posing a challenge for storage and disposal.
In 2018, SHIMA DENIM WORKS saw an opportunity to transform this waste into a valuable resource. They envisioned a denim brand that would not only celebrate Okinawan heritage but also embody the spirit of sustainability. The brand’s unique approach involves processing bagasse into a powder form within Okinawa, then transporting it to Mino City, Gifu Prefecture, where it’s combined with Manila hemp to create “Washi thread.” This thread is then woven into denim fabric in Fukuyama City, Hiroshima Prefecture, before being shipped back to Okinawa for final garment production.
SHIMA DENIM WORKS’ commitment to sustainable practices extends beyond the use of bagasse. The brand prioritizes domestic production to minimize carbon emissions from transportation, and they strive to ensure zero waste throughout their production process. The result is a unique denim collection that not only reflects Okinawan culture but also champions environmental consciousness.
The brand’s success lies in its ability to connect with both locals and tourists. While visitors are drawn to the novelty of the material, Okinawans resonate with the brand’s dedication to preserving their cultural heritage. The denim evokes a sense of nostalgia, reminding them of the sugarcane fields that have shaped their lives and their connection to the land. For many, it’s a symbol of their pride in their island’s resilience and innovative spirit.
Beyond the aesthetic appeal, SHIMA DENIM WORKS is playing a crucial role in revitalizing the sugarcane industry. By creating a demand for bagasse, the brand helps to ensure the long-term viability of the industry, creating new revenue streams and supporting local farmers. This initiative demonstrates the potential for upcycling and sustainable practices to create economic opportunities while protecting the environment.
As Katsuhiro Shimajiri, president of Yugafu Seito, one of Okinawa’s leading sugar refineries, aptly states, “Bagasse is not an industrial waste product; it’s a by-product of sugarcane that offers valuable resources.” This shift in perspective is crucial for a future where sustainability is not just a trend but a way of life.
The success of SHIMA DENIM WORKS is a testament to the power of innovation and collaboration. It is a story that transcends the boundaries of fashion, highlighting the potential for sustainable solutions to revive traditional industries and create a brighter future for both people and planet.
