Description

Souji is a mineral and vegetable-based liquid that when mixed, in the correct proportions with used cooking oil, and exhausted for 1 minute, immediately transforms into a multipurpose detergent with a pleasant aroma and without any manipulation risk, does not contain caustic soda, or any toxic or corrosive agent. The resulting detergent is 96% less polluting than a common one, and is useful as a dishwasher, laundry detergent, and floor scrubber. In addition to being ecological, cruelty free and presented in packaging formats that are sustainable with the planet.

Story

1l of used oil can contaminate up to 1,000,000 l of water (DEFRA) Only in Spain 150 thousand tons of oil waste are generated and more than 60% falls directly into the sewer, causing the death of thousands of species, and increasing 7 times the cost of water treatment. For this, and based on the old method of making soap with caustic soda, we spent 3 years of research to create a liquid without manipulation risks that would achieve the saponification reaction (transform a fatty acid into soap) in just one minute, with pleasant aroma and useful in multiple cleaning uses. (Floor scrubbers, dishwasher and laundry detergent) Thus, any person or establishment can carry out circular economics from the source, recycle used oil, reuse it, transforming it into ecological detergent, and reduce the impact of oil, common detergents and traditional packaging. In 3 simple steps, measure, mix, shake and go.

Clean Green Prize

This project is brilliant and deceptively simple. It is both low-tech and high impact. It combines systems of food, water, waste, and home living in an inspiring way. Perhaps most inspiring is how this project suggests that individual participation and experience is a critical element of circularity. As management of water and carbon become increasingly important in the climate emergency our world is facing, this project shines a light on how materials and waste affect ecosystems and resources long after they disappear from view. I wonder whether the adoption of this project—and the way of living it points to—could be fueled by grassroots empowerment. Could this product and technology be cooperatively-owned and open source? Could it lead to new business models as well as new social models? Could it offer an alternative to typical corporate marketing, development, and profit motives?

Many wonder what to do with used oil. This is an easy one for any kitchen. Neat!

SOUJI's innovative solution for used cooking oil is a win, win, win from several perspectives. It tackles the issue of what to do with used cooking oil, which other blocks drainage systems and can sometimes be carcinogenic, while providing a cleaning product that otherwise must be packaged, shipping and delivered to a customer most often in a single use plastic container. It is these kinds of scientifically innovative yet very sensible solutions which will disrupt the linear economy and provide better solutions for our earth.
