Retrofitting existing plants for low cost production of high performance building boards

Objective

A new process will be developed and implemented for cost effective production of a new generation of high performance gypsum-fibre boards (zeogyp-board) making more skilled use of conventional gypsum board production lines with low capital investment. Old gypsum boards will be used together with cellulose-fibres, fibrous clay residual from wastepaper and zeolite to achieve undistorted setting-behaviour of gypsum and to improve the strength and porosity of the board core resulting to higher surface hardness and lower application time and cost. Similar products have limited market share due to high production costs despite improved properties. The retrofitting approach prolongs the life cycle of over one hundred existing plants with low capital investment and maintains sustainable growth of the sector. It solves problems related with landfilling leading to zero waste production and reduces raw gypsum requirements. It responds to consumers ' needs.
