Second gypsum recycling plant on the cards for UK

NWGR developed its technique to recycle wet plasterboard in the 1980s. Mr Harker said: “Anyone can beat up dry plasterboard and remove the paper, the difficulty comes when the plasterboard is wet, we have developed a technique using a very specific grinding and screening process which allows us to recycle the gypsum when wet.”

Microstructure of Recycled Gypsum Plaster by SEM

Gypsum waste from building constructions is a material which can contaminate the soil and groundwater if is disposed directly in the soil or landfill without any control. In Brazil, these wastes are considered a recycle and/or recovery material, but the research of gypsum plaster recycling are very few at this moment. In this way, this work presents the microstructural characterization of two
