Wool & the Carbon Cycle

You are here

All life on earth is based on carbon. Each year, some 155 billion tons of atmospheric carbon is converted to biogenic carbon by photosynthesis, absorbing in the process some 130 trillion watts of solar energy. Sheep consume this biogenic carbon when they eat grass, and transform it into the amino acids of the wool fibre. 40% of the weight of clean wool is pure biogenic carbon. Read this fact sheet to learn more about the carbon cycle and the difference between biogenic and fossilised carbon – which is what synthetic fibres are made of.
