dc.description.abstractPlasterboard use in Europe is increasing, and so is the corresponding waste (CDW), with a considerable amount ending up in landfills. In the last decades, plasterboard producers have invested in plasterboard waste recycling to partially incorporate it into new plasterboard production. Nonetheless, these facilities are almost non-existent in the Iberian Peninsula (Portugal and Spain). In response to these challenges and the European Green Deal, Eurogypsum has established a set of recommended quality criteria for recycled gypsum from plasterboard and other gypsum-based products. However, specific regulations on managing this type of waste remain absent, and the use of recycled gypsum materials is still insignificant. To find new applications for it, evaluating the impact of the recycling process on the properties of the gypsum plaster obtained is mandatory. This work was developed within the framework of the G2E project, aiming to study the incorporation of recycled gypsum and paper waste into new plaster formulations. The particle size distribution, moisture and binder content were determined in four types of samples: recycled gypsum from plasterboard waste (RGPW) from a waste management company in Portugal, RGPW from a specialised facility in Italy, RGPW obtained from the manual separation of waste plasterboards, and raw gypsum. The plaster/water ratio, setting times, and fluidity of the samples calcined in the Laboratory were tested to determine which best fulfilled the requirements of EN 13279-1 standard for gypsum and gypsum-based products. Although further research is still needed, the results obtained showed that recycled gypsum from plasterboard waste is a promising option to be used as an alternative binder in the production of gypsum-based plasters and mortars for the buildings construction industry.en
