Mortars were formulated by substituting 25% of cement by volume with glass powders from fluorescent lamp glass and green bottle glass. The experimental program evaluated mechanical strength, durability parameters and ecotoxicological performance. Results revealed that clean fluorescent lamp mortars showed the most promising mechanical behavior, exceeding the reference in long-term compressive (54.8 MPa) and flexural strength (10.0 MPa). All glass mortars exhibited significantly reduced chloride diffusion coefficients (85\u201389%) and increased electrical resistivity (almost 4 times higher), indicating improved durability. Leaching tests confirmed that the incorporation of fluorescent lamp waste did not lead to hazardous levels of heavy metals in the cured mortars, suggesting effective encapsulation. By addressing both technical (mechanical and durability) and ecotoxic performance, this research contributes in an original and relevant way to the development of more sustainable building materials.<\/jats:p>","DOI":"10.3390\/sci7030107","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T09:41:17Z","timestamp":1754300477000},"page":"107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["WEEE Glass as a Sustainable Supplementary Cementitious Material: Experimental Analysis on Strength, Durability and Ecotoxic Performance of Mortars"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6922-9813","authenticated-orcid":false,"given":"Raphaele","family":"Malheiro","sequence":"first","affiliation":[{"name":"CTAC\u2014Centre for Territory, Environment and Construction, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-4235-2081","authenticated-orcid":false,"given":"Andr\u00e9","family":"Lemos","sequence":"additional","affiliation":[{"name":"CTAC\u2014Centre for Territory, Environment and Construction, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9677-3627","authenticated-orcid":false,"given":"Aires","family":"Cam\u00f5es","sequence":"additional","affiliation":[{"name":"CTAC\u2014Centre for Territory, Environment and Construction, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3497-4901","authenticated-orcid":false,"given":"Duarte","family":"Ferreira","sequence":"additional","affiliation":[{"name":"CTAC\u2014Centre for Territory, Environment and Construction, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Juliana","family":"Alves","sequence":"additional","affiliation":[{"name":"ICS\u2014Institute of Social Sciences, University of Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7376-3557","authenticated-orcid":false,"given":"Cristina","family":"Quintelas","sequence":"additional","affiliation":[{"name":"CEB\u2014Center for Biological Engineering, University of Minho, 4710-057 Braga, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,2]]},"reference":[{"key":"ref_1","unstructured":"(2023).
