Hey,

Welcome to Green Jobs Rising!

After you have fried fries and dumplings and the cooking oil is spent, what do you do with the used oil? Discard it?

Here is one striking fact: just 1 liter of oil can pollute up to 1,000 liters of water if discarded improperly.

One entrepreneur from Tunisia set out to change that.

Sabrine Chennaoui is a Tunisian deep tech enthusiast and eco-innovator driving sustainable change. 

Through MONSAPO, a company dedicated to transforming waste into sustainable resources through circular innovation in the cleaning industry, Ms. Chennaoui is leading the charge in climate tech with a machine that converts used cooking oil into eco-friendly cleaning solutions. 

As she says, “sustainability should be practical, local, and circular.”

She is the founder of MONSAPO and holds a Bachelor’s degree in Business Administration and a Master’s degree in Marketing from the Mediterranean School of Business. 

Sabrine is passionate about entrepreneurship, sustainability, and empowering women in business.

On her LinkedIn page, she writes:

““It’s too artisanal.”
“It will never scale.”
“Natural detergent can’t compete with industrial chemistry.”
“It’s just nostalgia.”
These were the arguments when petrochemical detergents replaced traditional formulas made from natural oils — the same process our grandmothers once mastered by hand.
By the 1950s, advertising convinced the world that synthetic meant progress and nature was outdated.
But what we gained in convenience, we lost in sustainability:
70 million tons of CO₂ emitted each year by detergent production,
80% of used oils discarded into water and soil,
Less than 10% of cleaning product packaging ever recycled.
Today, history is repeating itself.
The world is realizing that the future of cleaning must return to its essence — circular, natural, and intelligent.
That’s why I created Monsapo.
Through Sapocircle, we merge chemistry, IoT, and AI to turn used cooking oil into ready-to-use cleaning products directly on-site.
💧 2 L of oil = 8 L of eco-detergent.
No petrochemicals. No waste. Just smart circular technology.
Our grandmothers called it tradition.
We call it deeptech for sustainability.”
