Kazakh scientists are preparing for the upcoming international exposition. They are going to present their ‘green technology’ developments. One of such know-hows can improve people’s lives. It is a poplar tree that doesn’t produce any white fluff. Kazakh biologist-breeder Valentina Obodovskaya brought out this type of tree. The first balsamic poplar was planted six years ago.

 

Poplar tree releases 2-3 times more oxygen than an oak, birch, pine or maple. They don’t require much of coaxing. It is one of the few trees that can survive in harsh urban conditions. However, they produce lots of white fluff in summer season. Therefore people prefer either to cut down poplar trees or avoid them. This can affect the environment, ecologists say. Therefore, the Kazakh biologist has created a greenhouse full of unique trees in Kostanay.

- During the summer period, one tree absorbs up to 34 kilograms of dust and releases oxygen day and night.

 

Scientists of Buketov Karaganda State University are ready to amaze Expo visitors too. At present, they are actively developing a new type of the second generation biofuel. It is produced from the widespread wormwood and yarrow that grow in the steppe. The plants are stored at the university’s laboratory.

 

There is plenty of wild grass in Kazakhstan. There are nearly 500 species of wormwood, and over 150 species of yarrow. Both stems and leaves are utilized in the production. Unlike other materials aimed at producing biofuels, local wild grass is easy to process.

- We use dry distillation technology. The process of thermal decomposition of raw materials occurs in the temperature range of 250-300 degrees.

 

Scientists say that one ton of wild grass can be used to produce up to 200 kilograms of biofuel. It has high ecological indicators. It can be used as an additive to gasoline in order to reduce carbon dioxide emissions and improve fuel properties.

For instance, if we add our biofuel into RON 80 then we will get higher concentration gasoline such as RON 95. We are still improving the biofuel properties.

 

It is just a laboratory sample now but the prospects for industrial production are huge. These perennial grasses are easily cultivated in steppe soils and contribute to its enrichment. The scientists are planning to patent their invention.
