Liquid3
Liquid 3 (also known as Liquid Trees) is a clean energy photobioreactor project designed to replace the function of trees in heavily polluted urban areas where planting and growing real vegetation is not viable. The project was designed by the Institute for Multidisciplinary Research at the University of Belgrade. The United Nations Development Programme (UNDP) selected Liquid 3 as an "innovative" solution for "Climate Smart Urban Development," a project produced in partnership with Serbia's Ministry of Environmental Protection and the municipality of Stari Grad. Overview The Liquid3 algal photobioreactor is powered by solar panels. The glass tank is embedded into a structure that acts as a bench and is outfitted with other utilities such as charging ports. Similar to other photobioreactors, air is sucked through a pressure pump and fed to the microalgae, with oxygen released as a byproduct. Additionally, the Liquid 3 bioreactor can filter out heavy metal contaminants in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CityTrees
CityTrees, also known as Robot Trees, Robo-Trees, and Moss Walls, are large air filters installed in many European cities, as well as Hong Kong, that remove pollutants from the atmosphere. CityTrees are large structures covered in moss. The filters intend to curb harmful emissions from nearby traffic congestion, including fine dust particles and nitrogen oxides, of which they are claimed to take in 80%, although this has been disputed by some experts. The structures have been criticised, especially in Cork, Ireland, for their perceived ineffectiveness, possible wastage of energy and water, and costs of around €400,000 per year. Following this criticism, a Cork City Council debate on the CityTrees scheme was held on 13 November 2023. Councillors decided that the data available for the CityTrees was too inconclusive, partly due to the windy conditions where they were placed, and so they will remain for another 6–12 months. History and development The developers of CityTree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photobioreactor
Moss photobioreactor to cultivate mosses like ''Physcomitrella patens'' at the laboratory scale A photobioreactor (PBR) refers to any cultivation system designed for growing photoautotrophic organisms using artificial light sources or solar light to facilitate photosynthesis. Photobioreactors are typically used to cultivate microalgae">Photoautotrophism">photoautotrophic organisms using artificial light sources or solar light to facilitate photosynthesis. Photobioreactors are typically used to cultivate microalgae, cyanobacteria, and some mosses. Photobioreactors can be open systems, such as raceway ponds, which rely upon natural sources of light and carbon dioxide. Closed photobioreactors are flexible systems that can be controlled to the physiological requirements of the cultured organism, resulting in optimal growth rates and purity levels. Photobioreactors are typically used for the cultivation of bioactive compounds for biofuels, pharmaceuticals, and other industrial uses. ...

Ministry Of Environmental Protection (Serbia)
The Ministry of Environmental Protection of the Republic of Serbia () is the Ministry (government department), ministry in the Government of Serbia which is in the charge of the environmental protection. The current minister is Irena Vujović, in office since 2020. History The ministry was established on 31 July 1991. Over the years, several departments were added and removed in the Ministry's jurisdiction. The area covered by the Ministry mostly included Environmental Protection, Natural Resources, Spatial Planning. From 2004 to 2007, the Environmental Protection department was under Ministry of Science (Serbia), Ministry of Science jurisdiction. In 2011, the Mining department of the Ministry of Mining and Energy (Serbia), Ministry of Mining and Energy was added to the Ministry only to be removed in 2014.

Stari Grad, Belgrade
Stari Grad ( sr-Cyrl, Стари Град, ) is a municipality of the city of Belgrade. It encompasses some of the oldest sections of urban Belgrade, thus the name (‘’stari grad’’, Serbian for “old city”). Stari Grad is one of the three municipalities that occupy the very center of Belgrade, together with Savski Venac and Vračar. History Even though some of the oldest sections of Belgrade belong to Stari Grad, the municipality itself is among the latest urban ones formed administratively. It was formed by the merger of the municipality of Skadarlija and part of the municipality of Terazije on January 1, 1957. Geography Stari Grad occupies the ending ridge of Šumadija geological bar .The cliff-like ridge, where the fortress of Kalemegdan is located, overlooks the Great War Island and the confluence of the Sava river into the Danube, and makes one of the most beautiful natural lookouts in Belgrade. With Novi Beograd, it is one of 2 municipalities of Belgrade (out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smog Tower
Smog towers or smog free towers are structures designed as large-scale air purifiers to reduce air pollution particles (smog). This approach to the problem of urban air pollution involves air filtration and removal of suspended mechanical particulates such as soot and requires energy or power. Another approach is to remove urban air pollution by a chimney effect in a tall stack or updraft tower, which may be either filtered or released at altitude as with a solar updraft tower and which may not require operating energy beyond what may be produced by the updraft. World's first air cleaning tower The world's first smog-free tower was built by Dutch artist Daan Roosegaarde. It was unveiled in September 2015 in Rotterdam and later similar structures toured or were installed in Beijing and Tianjin, China, Kraków, Poland, Anyang, South Korea and Abu Dhabi. The 7-meter (23 ft) tall tower uses patented positive ionisation technology and is expected to clean 30,000 m3 of air per ...
