Biological Landfill Leachate Treatment Invented by Iranian Expert to Generate Oxygen

Mehdi Badri told ANA that the biological treatment of landfill leachate converts carbon dioxide into oxygen and this will increase the efficiency of greenhouses by 30 percent.

Garbage leachate is one of the most polluted liquids on the planet so a glass of it can dry up a whole and sturdy tree.

Therefore, if the leachate enters the surface and subsurface water, it causes a lot of pollution and can cause 118 types of disease, Badri explained.

He made the remarks on the sidelines of the national Asreh Omid Event which was held in late May in Tehran’s Grand Mosalla with the participation of 3,000 knowledge-based companies, laboratories, research teams, and startups.

He went on to say that urban waste leachate processing is done in different ways in the world. But the methods are in physical, chemical, and biological forms and sometimes require pre-treatment.

For example, to purify the leachate by biological method, we have to spend up to 270 days to filter the compounds, he added.

The most important advantage of this method is that sanctions cannot affect it, Badri said, noting that equipment wears out quickly due to high acids in water, while in this system the equipment is not used so much that acids affect it.

Another problem is the production of greenhouse gases so if someone wants to filter all the leachate, between 50 and 70 thousand tons of carbon dioxide will be produced.

In the biological treatment method, we will be able to transfer garbage leachate to the greenhouse. In this case, not only carbon dioxide will be converted into oxygen, but it will also increase the efficiency of greenhouses by 30 percent.

It means that the efficiency of a greenhouse which is about one ton will increase up to 1.3 tons.

Badri emphasized that the biological leachate treatment system has no foreign-made counterpart.
