From solutions for the future
Used since the dawn of time for clothing, food, paper, ropes, ropes and sails, hemp has gradually been replaced by cotton and synthetic materials from petroleum.
The number of its uses remain varied and are in increase:
- materials construction (bricks, insulation)
- paper, banknotes, cigarette papers
-structures and elements cars / planes
Its culture consumes little water, does not require pesticides and little input, structures soils and fossilizes as much CO2 as trees.
Microscopic algae have been consumed for thousands of years around the world.
In the natural environment they produce by photosynthesis half of the oxygen in the air and cultivated, in raceways or photobioreactors, they are used as food or used in the manufacture of cosmetics, biofuels or bioplastics.
The energy of sea currents, tides and rivers is inexhaustible and can be used to turn electric turbines.
The electricity thus produced can be connected directly to the networks or transformed by various processes to facilitate the storage and transport of the accumulated energy and to diversify its use.
Plastic has taken an important place in our way of life, it is found everywhere: in our clothes , vehicles, homes, packaging ...
In France, barely 25% of waste plastics are recycled.
A part is cremated and the rest is sent in bales in other Asian countries or from Africa or they very often end up in rivers, seas and oceans.
Rejected in nature, this waste slowly degrades into fine particles that we find from the ocean floor to the highest peaks of our mountains through the fish we eat.
Added to the other pollutants that we ingest (fine particles, residue of agriculture ... ), they constitute a real danger to our health as well as that of other animal species.
