On “earth plus,” Environmental Purification Technology
earth plus is a safe, sustainable and clean ceramic composite that solved challenges related to Photocatalysis. This chemical-free technology will surely become an innovative environmental technology.
History of Photocatalysis
In 1967, Mr. Akira Fujishima discovered that, with UV light, titanium dioxide generates water and oxygen. In 1972, he published this discovery as “Honda-Fujishima-Effect” with Mr. Honda in Nature. Although this discovery/technology attracted attention as an alternative energy source for petroleum, it has not been put to practical use for forty-four years now. In 1990, deodorization and sterilization effects by oxidative decomposition were discovered. In 1995, super-hydrophilic function was discovered.
earth plus”-Components, Form, and Safety
1. It consists of a powder made of titanium dioxide (used in the white color of white chocolate), a minuscule amount of silver (used in silverware), and Hydroxyapatite (in dental implant). They are approved as food additives in Japan.
2. My company owns material technologies (patented): melt-type that does not use resin binders (for water purification) and paint-type in which the abovementioned powder is dispersed in resin binders (for air purification -> with the use of textile materials, building construction materials, etc.)
Overcoming “Problems with Photocatalysis”
1. Melt-type: Titanium dioxide shows three crystal structures: Anatase used in photocatalysis and rutile and brookite used in cosmetics goods. The liquid crystal transition temperature is found at a 915°C±15°C or higher where anatase is commonly understood to change into rutile. Forming a catalytic melt film used to be impossible; the melting point of 1825°C means that everything turns into rutile, which was believed to be a non-reversible reaction. However, my new technology of instantaneous melting has made it possible to create a catalytic melt film that contains anatase.
2. Paint-type: Photocatalysis did not have the ability to distinguish bacteria and paint materials, both of which are organic matter. Also, photocatalysis did not work without UV irradiation. Because instant effectiveness is not necessary if continuous sterilization is available, I solved these problems in the following manners: I lowered the reactivity to the point where paint materials remain intact and I also utilized the peculiarity of Hydroxyapatite in which it selects and chemically adsorbs proteins, such as bacteria and allergens, etc., that are organic matter. Medical/chemical substances, being effective only when used with water and consumable by use, always require their instantaneous effects to be utilized; but, earth plus has made continuous/long-lasting sterilization possible for the first time.
A New Concept of sterilization with earth plus
1. The components of earth plus do not dissolve into water and they work continuously, which differentiates earth plus from chemicals.
2. Hydroxyapatite selectively collect and hold bacteria tightly and kill them gradually.
3. 1&2 mentioned above enabled the following; (a) Also by purposely lowering the sterilization effectiveness down to the level where paint materials do not get decomposed, the combination of the components can be selected with more varieties (b) Since the process does not require any water, earth plus works even in dry conditions (c) Total Solution, which is a comprehensive way of applying earth plus to the food, clothing, and shelter aspects in the living environment, is a proposal that I make for a new type of a safe, long-lasting, and effective form of sterilization.
~ Hence, earth plus, water-insoluble and sustainable, will change the style of sterilization being much more suitable for daily life. ~
