We design communities that fully integrate waste reprocessing and ecosystem revitalization into their infrastructure, enhancing soil health, purifying water, and building a foundation for a truly sustainable future.

Project: TOILETOWA - A Revolutionary Closed-Loop Flush Bio-Toilet at Ishizaka Sangyo


TOILETOWA leverages the power of microorganisms to break down and ferment waste, transforming it into valuable resources while producing active water that improves soil biodiversity and water quality over time.

As a trailblazer in regenerative biomaterials and circular economy technology, TOILETOWA places Japan at the cutting edge of environmental innovation. It is a cornerstone in JIEN’s mission to drive forest regeneration and sustainable living, proving that even the most basic human necessities can be reimagined for a greener future.

Beyond its technical excellence, TOILETOWA fosters environmental education, offering practical lessons in sustainability and demonstrating how every ending can evolve into a new beginning.

Recognized for its groundbreaking impact, TOILETOWA is officially nominated for the 2024 and has won Bronze in the public community categories & Sustainable Space at the 2024

【Toiletowa】100% circulation flush toilet installed at Ishizaka Sangyo in Saitama Prefecture, Japan, seamlessly integrates architecture and bio-fermentation technology with the ecological design by JIEN co-founders Tono Mirai and Yukako Saito.

This groundbreaking system represents the first biodiversity regeneration project that fully incorporates JIEN's Rewilder concept, incorporating the BioLoo solution.

Currently, it is being considered for implementation in multiple countries, showcasing its versatile applications. In Italy, we are exploring its use to address water scarcity in the wine-producing region of Piedmont.

Discussions with regional initiatives in Finland further highlight its potential for restoring water quality in the lake region.

Furthermore, the solution is being considered for public toilets in waterborne transport stations in Venice and on the island of Giudecca, serving as a sustainable alternative.

The system is positioned to play a pivotal role in water conservation by implementing water circulation and promoting the recovery of soil microbial diversity.

Moreover, we are actively engaged in discussions about establishing a Resilience Center in earthquake-affected areas in Turkey. This proposed center aims to offer sustainable solutions, with our innovative BioLoo system serving as a crucial element in this initiative.

This underscores the adaptability and versatility of our toilet solution in addressing various environmental challenges, ranging from water conservation in agricultural regions to the creation of resilient infrastructure in disaster-stricken areas.

The potential deployment in Italy, Finland, and Turkey underscores the global applicability of our bio-toilet solution, providing a sustainable and effective means to address pressing environmental concerns.
