Integrated Wastes-Resources Recycling System
ShinMaywa Tile Production System

In the light of limited capacity of available landfill sites, it is now strongly requested that incineration ashes produced from incineration facilities should be more positively reduced in size and properly disposed of so that the limited resources are used more effectively. To meet such requirements, ShinMaywa has developed a new tile production system that uses the incineration ashes for the material to produce building tiles.

(OUTLINE)

Making good use of unused materials such as incineration ashes and others, this system produces large-sized ceramic tiles, a highly value-added building material, that play an important role in giving a good appearance and preserving the environment.

(FEATURES)

 1. An energy-saving, cold processing method is employed unlike the conventional 
    ash fusing method.

2. High productivity realized by continuous burning for production.

3. Other than the incinerated ashes, such waste materials as molten slugs, incinerated sludge ash, glass cullets, concrete rubbish (waste building materials), waste casting sand are also well used to produce the tile.

ADVANTAGES OF ASH TILE

1) The product ash tiles are completely harmless to human health.  This is because
   dissolution of heavy metals from the incinerated ashes is fully protected.

* Typical dissolution test results: Ash tile containing 50% of incinerated ashes produced under request from Y city.

2) Once wet, this environment-friendly pavement tile continues to be moisturized 
   even in the dried atmosphere although it has an inherent permeable nature.

3) Use of this tile is subsidized in Japan. This is because the Ministry of Construction recommends this tile in their model project plans drawn for development of common environment residential areas.

4) The ash tile is durable enough to meet JIS A 5202 Floor Tile Bending Strength.

* Properties of ash tile containing 50% of incinerated ashes produced under request from Y city.
