Tannins: a gift from nature

Long ago, humans discovered that plant tannins could repel bacterial attack without discriminating between defending plant tissue or animal proteins. In an ironic human-directed twist of evolution, we repurposed a plant’s evolved defense against microbes to protect animal tissue against microbial attack.

Natural tannins are sourced from different plants, present either in bark, leaves, wood, fruits or roots. Ecotan products utilize 5 tannin sources: chestnut and quebracho wood, tara pods, gallnuts and olive tree pruning. Tannins are extracted simply in hot water and without the use of any chemicals. Spent materials from the production process rejoin nature as clean water or are upcycled into useful products like wood pellets.

Life Cycle Assessment

Ecotan tannins have undergone an LCA (Life Cycle Assessment), a cradle-to-gate analysis which assesses the environmental impact associated with all the stages of a product’s life. Silvateam is the first in the industry to certify the carbon footprint value of its products, expressed as the number of kilograms of carbon dioxide emissions (CO2e) per kilogram of product analyzed. For instance, we have reduced the environmental impact of chestnut tannin production by 60% (GWP 100 Kg CO2e).

Silvateam has been the first in the tannin industry to certify a Deforestation Free supply chain according to the PEFC standard, responsibly sourcing wood from chestnut (PEFC Certificate N. 27910) and quebracho (PEFC Certificate N. 006971) forests used as a source of raw material. The PEFC certification is a seal of attention and care for the environment, the protection of the woods and the communities that are part of it.
