The Tree

The tree

The Pongamia tree has a proven track record (University of Queensland, Australia). The tree roots fast and solid and is drought, disease, and germ -resistant. After nine months, the tree is planted.

Pongamia trees are highly yielding and will be harvested yearly. The first harvest will take place after three to four years. The tree reaches full production capability at the age 6 to 7 depending on the environmental conditions.

The Nut

After harvesting, the nuts are crushed and the shell is separated. The nut is pressed to extract crude oil, from which green, renewable fuel will be refined.

The residue of crushing is used as protein for cattle feed. The shell of the nut is used either as biomass or as an organic fertiliser.

The Oil

Green Fuel

HVO (Hydro-treated Vegetable Oil) is also known as ‘green diesel’ or, in the US, as ‘renewable diesel’. Due to its advantages compared to fossil diesel and first generation regular biodiesel, HVO is rapidly gaining popularity on European and global markets with an increasing number of companies investing in this new technology. Key HVO players include Neste, Total, ENI, ConocoPhillips, BP, PetroBras, Shell, Nippon Oil and REG.

HVO is a cleaner product than fossil diesel, can be blended without limits and also upgraded to jet fuel. It’s a drop-in fuel which can be used without blending limits and without any damage to the existing diesel engines. This basically means that the more we drive and fly on HVO, the greener our planet gets.

The Land - Cattle Grazing

The method used is called “Silvopastoral Agriculture“. This means that we use the land for trees and livestock simultaneously. The leaves and nuts of Pongamia trees are not toxic (such as Jatropha), but do have a nasty taste which allows for cattle grazing under and around the trees.

As an additional advantage, the Pongamia trees’ roots produce nitrogen (a natural fertilizer) causing grass to grow abundantly around and under the trees without the need of chemical fertilizing. Besides, the cows and sheep produce a natural fertilizer as well (yes…shit). To top it off, the protein from the nuts is used as food for the cattle – which makes the circle round again.

The advantage of this system is no land is needed that would otherwise be used for food production. The lands are used for food and Pongamia trees simultaneously.

Pongamia plantations will become a very interesting option to extend the use of land from existing cattle breeding and grazing and thus increase revenues for adjacent landowners.  The Paraguayan beef production forecast for 2018 is estimated at a record of 620,000 tons. This places Paraguay as the 3rd largest exporter of beef in South America and 5th in the world.

The Reforestation Site

Our partners’ reforestation site is located in Alto Paraguay, Paraguay. The River-side ‘Estancia’ is situated on the Rio Paraguay; the border between Brazil and Paraguay. The company, originated in Rotterdam, is led by an European management team (Paris, Amsterdam and London) and uses local expertise and employees (social impact). The used Agri-techniques and genetics originate in the United States and in Australia.
