Used since the dawn of time for clothing, food, paper, ropes, ropes and ruffles, hemp has gradually been replaced by cotton and synthetic materials derived from petroleum.
The number of its uses remains varied and is increasing
-building materials (bricks, insulators)
-clothes and shoes
-strings, strings
-papers, banknotes, cigarette papers
-litter and straw
-structures and elements of cars/airplanes
-fuels
-food(oil, grain, flour)
-paints, varnishes
-cosmetics
Its cultivation consumes little water, requires no pesticides and few inputs, structures soils and fossilizes as much CO2 as trees.
HEMP
Microscopic algae have been consumed for thousands of years around the world.
Used as food by some populations in Africa, Mexico or Japan, they also serve as a food supplement to fight malnutrition or for aquaculture.
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 enter the manufacture of cosmetics, biofuels or bioplastics.
The inexhaustible energy of marine currents and tides can, like that of rivers and streams, be used to turn electric turbines.
The electricity produced can be connected directly to the grids or transformed by various processes to facilitate the storage and transport of the stored energy and thus diversify its use.
MARINE ENERGY
Wood, raw earth, plant fibers, and lime have always been used in construction.
Cement, metal, fiberglass, and petroleum-based insulation gradually replaced them.
The world production of plastic materials is 460 million tons per year. 75% of these plastics are not recycled.
