Characteristics

Supersol is perfectly recyclable, from the soil and back to the soil.

Even when Supersol is compacted, it retains good water drainage. Its high water permeability, water retentivity and air permeability promote plant growth.

Supersol is an inorganic mineral and fire-resistant.

Supersol can be made to have different specific gravities depending on its use.

It is possible to produce Supersol having different characteristics by changing the types of add-in materials, milling conditions and baking conditions.

Supersol is adaptable to various application conditions, such as a place of complex topography or where there are underground pipes. It is easy to handle, and can be handled even in the rain.

• * Very light
• * Easy to handle as a banking material and can be applied in ordinary procedures.
• * Does not need curing.
• * Since Supersol is made from glass, no harmful substance is dissociated from it. Thus, it is very safe to the environment.
• * Since Supersol is an inorganic mineral, it is chemically stable and does not corrode.

How It Was Developed

Supersol production technology was developed by the Kishimoto International Technology Institute under the "Research and Development Business Cooperation Contract" signed in February 1997 with the Clean Japan Center" (CJC) as a project to which a supplementary budget was granted in 1996 by the Ministry of International Trade and Industry (currently the Ministry of Economy, Trade and Industry) and which was entrusted to CJC by the New Energy and Industrial Technology Development Organization (NEDO) as a verification test of glass cullet recycling.

Based on the result of this project, Trim Co., Ltd. developed a Supersol production system (plant) for practical use. Today, Trim has built the plants arround Japan and is promoting community vitalization through recycling.
