Pineapple, vanilla, sugar cane: the second life of these exotic ingredients

On your next vacation to the four corners of the world, you can cross their paths. After you leave, these three exotic products will be recycled for a good cause…

Pineapple to get rid of bad fats

Did you know that pineapple leaves, when burned or left in fields after harvest, produce greenhouse gases? In Singapore, the national university has found a way to kill two birds with one stone by recycling them while helping us better maintain our health. Researchers forced themselves to dry and grind them to obtain a powder with unexpected powers: absorb the cooking fats that we ingest during a meal. In concrete terms, this is done in the form of capsules that must be swallowed. The miracle cure has even been adapted in the form of potato chips. Scientists are now trying to market their discovery… Good for you!

Vanilla to make bioplastic

It will flavor the rice pudding. It’s essential for custard… And it can also help reduce plastic waste. Vanilla – or rather vanillin, the main component of the pod, has been used by researchers at the University of Bowling Green in Ohio (USA) to making bioplastic† In a study published a few days ago in the journal Angewandte Chemie, American scientists explain that they have succeeded in destroying matter when it comes under an ultraviolet radiation of 300 nm. At this scale, the components are stimulated to initiate a chemical reaction until the polymer breaks down.

Sugarcane to provide electricity

Bagasse is not only used to make eco-friendly straws. In Mauritius, the fibrous residue obtained after crushing sugar cane replaces coal for power thermal power plants. 14% of the paradise destination’s electricity needs are supplied by this system, which runs at full capacity when the sugar cane season is in full swing, ie in winter (from the end of the year), summer for Europe). According to the target of the government of the country of the dodo, the share of renewable energy supplied by Mauritius should be 35% by 2025.
