Moreover, gasification allows a sustainable management of wastes and reduces the use of fossil fuels responsible for the increment of greenhouse gases. This work aimed to perform gasification tests with solid recovered fuels (SRF) containing organic fractions mainly retrieved from construction and demolition wastes to assess the potential for energy conversion. Tests were conducted in a pilot-scale downdraft gasifier (maximum feedstock input of 22 kg\/h) at c.a. 800 \u00b0C, using SRF samples containing different proportions of polymeric wastes ranging between 0 and 20 wt %. Gas and chars obtained as by-products were analysed to evaluate their properties and to establish valid pathways for their valorisation. The addition of polymeric wastes reduced char production but rose both tar and HCl concentrations in the gas. The SRF with 10 wt % of polymeric wastes generated the best results, producing the highest calorific value for the gas (3.5 MJ\/Nm3) and the highest cold-gas efficiency (45%). Possible char applications include their use as catalysts for tar decomposition, or as an additive in construction materials. Gasification can therefore be considered a valid solution for the energetic valorisation of these SRFs.<\/jats:p>","DOI":"10.3390\/en15218139","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T06:01:28Z","timestamp":1667282488000},"page":"8139","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Gasification of Solid Recovered Fuels with Variable Fractions of Polymeric Materials"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7817-2924","authenticated-orcid":false,"given":"Oct\u00e1vio","family":"Alves","sequence":"first","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8384-4433","authenticated-orcid":false,"given":"Lu\u00eds","family":"Calado","sequence":"additional","affiliation":[{"name":"Polytechnic Institute of Portalegre, 7300-110 Portalegre, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5408-6071","authenticated-orcid":false,"given":"Roberta M.","family":"Panizio","sequence":"additional","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"},{"name":"MEtRICs\u2014Mechanical Engineering and Resource Sustainability Center, Department of Sciences and Technology of Biomass, NOVA School of Science and Technology, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5733-902X","authenticated-orcid":false,"given":"Catarina","family":"Nobre","sequence":"additional","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"}]},{"given":"Eliseu","family":"Monteiro","sequence":"additional","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"},{"name":"Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2581-4460","authenticated-orcid":false,"given":"Paulo","family":"Brito","sequence":"additional","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0940-519X","authenticated-orcid":false,"given":"Margarida","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"VALORIZA\u2014Research Centre for Endogenous Resource Valorization, Polytechnic Institute of Portalegre, 7300-555 Portalegre, Portugal"},{"name":"MEtRICs\u2014Mechanical Engineering and Resource Sustainability Center, Department of Sciences and Technology of Biomass, NOVA School of Science and Technology, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,1]]},"reference":[{"key":"ref_1","unstructured":"Eurostat (2019, March 01).
