Joint industry-university research for effective use of the scrapped scallop shells



■ The development of collaboration between academia and industry research

    In 1999, the Hachinohe Institute of Technology (HIT) in Hachinohe, Japan and Chafflose Corporation, Co.,Ltd. in Yokohama, Japan started the collaboration between academia and industry for the year 2000 by discussing results for functions of the scallop shell materials obtained. The objectives of the collaboration were to investigate, develop, and manufacture scallop shell ceramics by applying the techniques of bionic design. Researchers at HIT will study the means of action and mechanisms of functions of the ceramics, while development and manufacturing will take place at Chafflose Corporation, Co.,Ltd..

■ As for practical applications

・Wall materials(Chafflose Corporation Co., Ltd.)

 Evidence has shown that scallop shell ceramics function in several ways due to their antibacterial action, deodorant action, reduction of formaldehyde that was derived from both wall materials and furniture and function of several volatile organic compounds (VOCs) in the atmosphere. With countermeasures for "sick building" now gaining prominence, then ceramics with scallop shells will present possibilities for applications not just in Japan but in countries around the world.

・ChaffClean(Chafflose Corporation Co., Ltd.)

 This product is the detergent which the powerful anti-fungus function of the scallop shell ceramics was applied to. This detergent is used to wash an egg, vegetables, tableware, cutting board,and so on. How to use it is easy. ChaffClean(scallop shell ceramics) is dissolved at the rate of 3 glasses of teaspoons in the water of 1 liter, and they are only pickled in this solution for about 3〜4 minutes, and they can be washed.

■ Development of target articles

  Given their excellent characteristics, scallop shell products are eagerly anticipated, such as detergents to prevent food poisoning, preservatives, wall material with or without an infrared heater panel used in a hospital to prevent in-hospital infections like Methicillin-resistant Staphylococcus aureus (MRSA), wall material to reduce formaldehyde and chemicals in the atmosphere for countermeasures against “sick” building syndrome in hospitals and eventide homes, and as a calcium additive.
