SOUJI converts your used vegetable oil into a soap/detergent.

Each time you throw out 1 litre of vegetable oil without recycling, you contaminate more than 1000 litres of water.

We are diminishing the future of the planet, of our children and of ourselves.

In a normal home, one disposes of approximately 1 litre of used vegetable oil every month, causing not only damage to the environment, but also to the water pipes of our homes, with the consequent economic expense. .

What differentiates us from other options?

SOUJI bases its philosophy on the concept of circular economy.
To do this, we follow the four-R rule:
Reduce, Recycle, Reuse and Recover.

We are water.
And we live in a planet mainly composed of water.
Water is the basis of life.

What are our clients’ opinions?
  • The truth is that I liked it very much, I am quite frank in this sense. We have always made homemade bars of soap, but it takes nearly a week to make it, and with SOUJI you have it in one minute.

    I was surprised at how good the house smells when you mop with it, and I was also surprised by how much and nice the bottle smells no matter where you have it, it fills the whole room with the SOUJI aroma.
