Why Paulownia?


- The tree Paulownia can adapt to almost any soil, having - in just 3-5 years - a growth rate and size that other tree species would reach in 25 years. In its early years, it may grow 2-3 meters / year.

- Due its rapid growth, it can shade an area in record time.

- It acts as horticultural shelter for vegetables and herbs, flowers, bulbs and nursery seedlings, offering them protection from wind and sun during summer.

- Thanks to the hairy coating on the underside of its leaves and stalks, this tree is a good sound absorber.

- In spring, it blossoms abundantly before going green, with beautiful large lilac flowers that spread around a discreet and very agreeable violet-like fragrance.

- The flowers are highly popular with honey-making bees. Being a good honey-bearing tree, it produces more honey than acacia (1200-1500 kg / ha). - Drives insects away, absorbs noise and dust.

- If cut or damaged, it regenerates very quickly.

- It adapts very well in the urban environment full of dust and pollutants, while its roots saves the ground from landslides.

- Its wood is closely similar to balsa wood, it dries quickly without cracking or deforming.

- Its leaves may be used as well for animal feeding.

- The trading value of this wood is comparable to that of the walnut and cultivating this tree can be a goldmine for investors - grade A quality lumber (60%), while residues (30%) can be used as biomass for obtaining electrical or thermal energy by gasification.

- It is particularly good for making furniture and plywood. When 7-8 years old, the trees can be cut and give a truncated average of about 0.6-1 m3 of wood. This wood is of excellent quality, easy, knotless and waterproof, an excellent raw material for the furniture, joinery and carpentry industry, but for more other special purposes as well, such as barrels or boats making.

- Paulownia-wood dries in 30 to 60 days without curving, warping, splitting or slicing. Furnace drying lasts between 36 and 60 hours, depending on furnace configuration, its horsepower and the timber size.

- Paulownia is resistant to degradation and rotting if not in permanent contact with the earth.
- Very good fire resistance, ignition temperature 420 to 430ºC as compared to hardwoods average of 220 to 225ºC.

- 1 Kg of dry timber has a calorific value of approximately kb. 4500 kcal (18830 kJ) to u = 13%, a very high value even as compared to quality charcoal types and a lot over all other types of materials.

- One hectare of plantation reduces an annual amount of 48 tons of dust and air pollutants.
- its strong roots that reach deep into the ground stop soil erosion, balance temperature fluctuations, improving the flow parameters and air humidity level. As such, it contributes to balance the climate in their environment.

- It's got large heart-shaped leaves that can reach over 70 cm in diameter; a 7-year old tree can produce up to 60 kg of leaves per year, being an ideal organic fertilizer and animal food source.

- The high content of proteins (9.5%) and nitrogen (15%) in the leaves may open new perspectives for livestock raising and soil improvement by using Bio-fertilizers.

- A 500- trees hectare collects a volume of some 100 CO2 t / year and produces 75 t of oxygen, the equivalent of a daily amount of oxygen needed for 205 people.
