CHIYODA CIRCULAR BOARD  Fulfilled board-to-boardCHIYODA CIRCULAR BOARD  Fulfilled board-to-board

  • The world's first gypsum board here means a gypsum board manufactured using 100% raw material made from modified waste gypsum board collected from construction sites (new construction and demolition) as raw material gypsum. (Researched by own & group company as of April, 2023 )
  • The heat source for the manufacturing of gypsum board is steam generated by a biomass boiler fueled by wood chips, which is interpreted as carbon neutral, and electricity is generated by renewable energy sources such as solar, wind, geothermal, hydroelectric, and biomass that exist in the natural world and can be used permanently.

Two issues surrounding gypsum board.Two issues surrounding gypsum board.

Landfill shortageLandfill shortage

While the amount of waste gypsum board discharge is expected to increase significantly in the future, there is concern that the controlled final disposal sites where waste gypsum board is disposed will be over loaded.

Difficulty of recyclingDifficulty of recycling

The recycling rate of waste gypsum board from new construction (used for gypsum board) is 60%, while the recycling rate of waste gypsum board from demolition (used for gypsum board) is only about 6%.

Chiyoda Circular Board has fulfilled “board-to-board” by reusing 100% of waste plasterboard.Chiyoda Circular Board has fulfilled “board-to-board” by reusing 100% of waste plasterboard.
Using 100% waste gypsum board for material

Normally, gypsum board could only be mixed with about 10% of the raw materials, but Chiyoda-Ute’s world-first technology for continuous crystal enlargement of waste gypsum has made it possible to reuse gypsum powder derived from waste gypsum board as raw materials without being aware of any restrictions on mixing ratio.

Carbon neutral for production

Woody biomass fuels such as demolition wood are used as heat source during production and electricity during production is derived from renewable energy which makes it possible to achieves carbon neutrality during manufacturing process.

Same high fire resistance as conventional products

Fire resistance and sound insulation properties are equivalent to those of ordinary products. It can be replaced as an environmentally friendly building material while maintaining its fire resistance and sound insulation performance.
