Dark gas emitted from cars and factories, Subway’s fine dust and yellow dust cause us to wear gas masks. WHO designated ultrafine dust as the first class carcinogen in 2013.Fine dusts’ diameter is from the size of 0.1~10㎛, and these dusts are the solid and liquid substances, such as dusts, asbestos and cadmium, floating in the air. Especially, yellow dust contains metal substances like irons, aluminium, magnesium and calcium, and other harmful chemical substances in the air in a significant amount which impacts seriously upon human health.  In fact, even if you do lots of exercise and eat eco-friendly food, if you breathe the air in urban area, this will be bad for your health. Such polluted fine dusts can cause not only cancer in the body, but also skin disease and atopy. When the dusts penetrate on your skin, this will be fatal to skin disease. Fine dusts cannot be taken away by water and soap. So, Spabano, with microbubble technology, is created.

Human beings can live the most healthy and happy. However, as the civilization has developed significantly, the people in the world pursues the convenience, and the people use concrete which is the mix of sand and pebbles with cement as construction material.  However, mining aggregate has become the destruction of environment, and it is not sufficient, so we cannot  use concrete no longer. So, we are going to use the soil which we can get easily and it is an optimal element for the health.  However, the soil does not mix well with the concrete which is the main difficulty, so the soil hardener is a chemical which overcomes such problems. Rather than sand, we can form a good environment with new environment-friendly technologies which can pave the road, walking trails, forest trails like cement with soil.Environmental friendly soil high strength hardener was only used in the huge-scale construction, but it is applicable to the areas of pavement, trails, parking lots, forest trails, bike roads, soft ground, farm roads, barn ground, front yard, small roads, blocks, plates, environment friendly soil house, and Hwangto floors.
