Rice is an important crop worldwide and in Europe. Different wastes are produced in the cultivation, harvesting and processing of this crop. Rice husk (RH) and plastics are two of these wastes from rice production. RH and polyethylene (PE) were characterised for different thermal, chemical, and ecotoxic parameters. Both these wastes were submitted to gasification and co-gasification assays. Bed and cyclone chars were collected and characterised for thermal, textural, chemical and ecotoxic parameters. The chars were mainly composed by Si. Texturally, they were mainly constituted by mesopores and micropores. The bed char produced with oxygen as the gasification agent presented the best textural properties with the highest surface area and micropore volume, being interesting to be further tested as an adsorbent material.
