For example, vegetable matter has the advantage of being able to be cultivated without their consumption leading to an apparent decrease in natural resources.
- renewable raw materials contain 14 C. All carbon samples taken from living organisms (animals or plants) are in fact a mixture of 3 isotopes: 12 C (representing about 98.892%), 13 C (about 1, 108%) and 14 C (traces: 1, 2.10 ⁇ 10 %).
