JStories ー Yearly on the evening of October 31, Tokyo’s Shibuya district is filled with revelers in elaborate costumes, swept up within the frenzy of Halloween. However when the occasion ends, the streets are left suffering from piles of trash, a jarring aftermath of the celebration.
From this rising waste downside, a small experiment has blossomed into an formidable venture geared toward making a round financial system, with Shibuya as its place to begin.
“We need to rework Shibuya from the ultimate cease of consumption into the start line of a brand new cycle,” says Takahiro Tsubonuma, idea designer and founding father of Shibuya Hiryo (Shibuya Fertilizer).
Shibuya Hiryo collects meals scraps and development particles, changing them into new merchandise: sweets created from greens grown in composted soil, and souvenirs created from concrete salvaged throughout redevelopment tasks.
“As an alternative of letting trash be burned and forgotten, I questioned if we may rework it into one thing that excites individuals, one thing enjoyable and significant,” he provides.
From this concept, Tsubonuma launched the venture Shibuya Hiryou. By 2021, the venture had grown into Shibuya Hiryou LLC, which now operates three flagship initiatives:
- Round Kits, plant-growing kits made with composted meals scraps.
- Round Cosmetics, soaps and natural workshops created from compost-grown herbs.
- Round Sweets, desserts created from greens grown utilizing composted waste.
Round Kits use mechanical composters put in on the rooftops of buildings in Shibuya, which flip meals waste into fertilizer, paired with seeds for simple planting. Round Cosmetics observe the identical precept: meals waste is composted on-site, herbs are grown, and individuals get pleasure from workshops the place they craft handmade soaps from the harvest.
“Composting faces strict authorized laws. It usually must be processed throughout the facility the place it’s generated, which is a problem,” Tsubonuma explains. “We’re additionally experimenting with rooftop vegetable gardens and modular planters that may be rearranged relying on the aim.”
Efforts to compost meals waste the place it’s generated have been tried in different areas, however hygiene issues and administration difficulties usually make them unsustainable. Mechanical composters, nonetheless, are easy and environment friendly: simply open the lid, toss within the meals waste, and inside 24 hours, compost is prepared.
Tsubonuma believes the true worth lies within the expertise itself. “Greater than self-sufficiency, what issues is how this course of can empower individuals, the way it can enrich their lives and encourage them.”
Shibuya Hiryou additionally works with kids to instill the rules of a round financial system. At a Tokyo kindergarten, they supported a program the place meals scraps from faculty lunches have been composted to develop greens, which the youngsters noticed and cared for.
“The youngsters begin seeing leftovers not as trash, however as one thing that may be reused,” says Tsubonuma. Sharing these observations on-line, he provides, helps join their actions to society at giant.
Round Sweets additionally entails composting a few of Shibuya’s natural waste at a recycling plant in Ibaraki, utilizing the compost to develop candy potatoes. The harvested candy potatoes are then bought in Shibuya and was merchandise, making a round system with a story the place natural waste from Shibuya turns into precious merchandise and returns to Shibuya.
Among the many firm’s flagship merchandise is the “Re-Macaron,” created from candy potatoes grown with composted waste at a recycling facility in Ibaraki Prefecture. When bought at Shibuya QWS, the macarons bought out two weeks sooner than anticipated.
In one other partnership, Shibuya Hiryou collaborated with Akita Prefecture to develop “Shibu-Hera Ice,” a playful twist on Akita’s beloved ice cream.
Shibuya Hiryou’s sweets not solely recycle waste but additionally give regional produce increased worth and a broader market. “We realized our work is about greater than recycling meals scraps. It’s about revitalizing native communities,” Tsubonuma says. “These round fashions may work not simply in Japan however overseas.”
One other distinctive initiative is “Shibuya Souvenirs.” Not like different areas of Japan, Shibuya might not boast well-known native specialties like Hokkaido’s milk or Ehime’s citrus, however Tsubonuma drew inspiration from the cityscape itself, significantly the long-lasting Scramble Crossing, often known as one among Japan’s most secure intersections.
By shifting views, Tsubonuma realized they might create souvenirs that protect Shibuya’s evolving story. Concrete particles from redevelopment tasks has been was “Architectural Souvenirs,” similar to desk organizers and magnetic instruments, in collaboration with Tokyu Development.
“Even when a constructing is gone, its story stays,” Tsubonuma says. “We are able to go that reminiscence on by means of the objects we create.”
Whereas Japan has loads of recycling applied sciences, Tsubonuma argues that the lacking hyperlink is creating techniques that give these supplies which means and worth. “Our job is to step in and create a framework that enriches the lives of individuals residing in these locations, each materially and emotionally,” he says.
Shibuya Hiryou’s imaginative and prescient is to scale its round experiments, develop its partnerships, and encourage each cities and rural areas to rethink waste as a useful resource.
