National Committee on Ecology and Climate Change of the Republic of Uzbekistan

At the booth of the Republic of Karakalpakstan, innovative solutions were presented for ecosystem restoration and adaptation to arid conditions. Among them was the “AquaPon” system, based on a closed cycle: fish live in water used to irrigate plants, and their waste serves as natural fertilizer. This technology is energy-efficient, requires minimal resources, and can be applied even in desert climates. In addition, visitors were shown three flasks with water of varying salinity: from moderately salty, where Artemia thrive, to highly salty containing the microalga Chlorella, and finally to extremely salty — completely devoid of life. These samples clearly illustrate the effects of salinization, characteristic of the dried-up Aral Sea bed.

Also on display were six containers with various soil types typical of Karakalpakstan, along with samples of native plants adapted to these conditions. The aim of the exhibit was to demonstrate the biodiversity of ecosystems and their potential for restoration. Six cubes with images of animals captured by camera traps in the region were also presented.

At the Fergana region’s booth, projects were presented for producing paper from banana peels. This eco-friendly paper can be used for making eco-bags and moisturizing face masks. A technology for producing stone paper was also showcased.

The Bukhara region presented a number of technological solutions aimed at combating pollution. One of the projects — Hydroguard — is designed to clean irrigation canals from plastic and other types of waste. The water flow turns a wheel that activates a lifting mechanism to deliver waste into a container. The uniqueness of this project lies in the fact that it does not require an external power supply — on the contrary, it generates electricity. In the future, there are plans to expand the use of Hydroguard in rural canals to create a cleaner irrigation system.
Also showcased was the EcoVortex wind turbine with a vertical axis. Unlike traditional horizontal turbines, it can capture wind from any direction without needing to rotate.

The Jizzakh region presented achievements and environmental challenges of 16 major industrial enterprises, innovative developments, green technologies, and educational materials. Particular attention was given to 18 startups — 12 in the field of production and 6 in environmental education. In particular, air pollution reduction filters produced by the Jizzakh-based company Taleng attracted the interest of foreign entrepreneurs.

The projects presented at the exhibition aim not only to solve the problems of individual regions but also contribute to improving the overall environmental situation in the region.
