Recycled Gypsum waste is reintegrated back into the manufacturing process wherever possible while maintaining product quality.32 The slurry is made up of stucco, water and additives in a continuous mixer and spread from 1-3 hose outlets onto a moving continuous sheet of paper then sandwiched with a top paper3. After rapid setting, along forming belt, the continuous sheet of plasterboard is cut into panels of specific length1. Natural and recycled gypsum are milled and calcined at around 160°C to produce stucco (plaster powder). Paper used for manufacturing plasterboards is 100% recycled4. The board is dried in a multi-level dryer to evaporate excess water and increase strength5. Finally the plasterboard is trimmed to the nominal length, stacked on pallets, stored and packed for shipmentFigure 2: Manufacturing process flow diagram. The manufacturing process is described in detail within the diagramConstruction process stage, A4-A5Description of the stage: A4: Transport to the building site.
