What is earthplusTM ?
1. supplement of transitory problem that medicament(chemicals) have
2. Having continuity
(1) example of paint type ( for general purpose )
Evaluation of continuity of earthplusTM by dipping treatment into fibres.
fibres that were used : T/C(4/6) Tetron Cotton
Weight per area : 140g/m2
Test method : according to JIS L 1902
bacteria that were used as text body : Staphylcoccus aureus
evaluation result : 2nd March 2001 incorporation foundation Japan Food Research Laboratories No. 301020123-001 |

(2) example of melt type ( high level of functionality )
earthplusTM is not one that acts through beginning to dissolve in water.
earthplusTM is a new material that ceramics that are approved as a food additive,
are compounded.
Continuance is conspicuous characteristic of earthplusTM (applied for international patent). |
Evaluation of continuous sanitizing of earthplusTM in water |
Continuous charging of Escherichia coli for 147 days
----- control ----- earthplusTM
|
We did put earthplusTM into 1 liter of water, we continued putting 1,000,000 of Escherichia coli into it every day for 147 days. Escherichia coli were not detected in every 24 hours inspection. |
|
3. being as ceramics composite material
earthplusTM is capable of controlling bacteria, viruses in the living environment
and of not decomposing paint, fibres etc.
earthplusTM uses silver (in the form of metal), the degree of elution of silver is
confirmed as only a few ppb by ICP-MS, in ultrapure water, 120 hours dipping
Also, a safety of earthplusTM is confirmed through a successive generations breeding of Oryzias latipes ( Killifish ) and a growth of from the parent fish to the young fish.

4. meaning of earthplusTM
earthplusTM means “technology for tuning nature and environment, sustainable technology.”
20th century has been one where the living environments ( water, air ) have been in safety and controlled comfortably through the benefit of medicament(chemicals).
On the other hand, drug-resistant bacteria occurred through the medicament(chemicals),
furthermore the higher degree of dependence on medicament(chemicals) gives
a burden to environment and human, environmental damage, spread of infection
are starting to spread while we do not recognize. |
