Seringa at a glance
- Hardest plantation wood on earth
- Planted and cultivated by small family farmers
- Stores up to 10 tons of CO2 (carbon) per acre in a year
- Produces latex sap for 25 years used in tires, medical and technical products (seals, etc.)
- Trees harden over time. Latex productions slows down and trees replaced by new ones
- Seringa works well with hand and machine tools and takes stain and colors well
CO2 absorption
Estimate per acre, per year
10 year old trees: 10 tons per year
25 year old trees: 6 tons per year
The trees absorb less carbon as they age. Carbon absorption is increased by cutting and replanting.

Seringa trees produce natural latex. Latex is used to make tires, medical and other scientific products. Natural latex can absorb and release moisture. Today, how the process is managed from latex to flooring is a positive environmental story. Here are the ways this wood is truly eco-friendly:
