| Résumé : |
Substances that may be present in leather products will leach out of leather (disintegrated or whole) when the leather is at its end-of-life phase. Whether in a landfill, on a kerbside, or in a garden at home, the substances move into the soil and enrich the life of that soil or will negatively affect the natural organisms present there. If the effects are positive, then the organisms, e.g. plants growing in that soil, will be enriched and will grow with greater health or vigour.
Leather is primarily collagen ; a carbon, nitrogen and oxygen rich substrate, but it can also contain the chemicals added to help with the tanning, lubrication and colouring of that article. The leather may even include natural minerals and salts that are stowaways in the material. When the leather breaks down through a disintegration, or composting process, the biomass or breakdown products become a nutritions source of elements for the growing seedling. |

- Fig. 3 : The absorption of soluble metals (insoluble metals like some metal hydroxides are not able to enter the plant roots system) into the roots and are transported to the leaves, e.g., metals in tea plants
