Mitigation measures are required to overcome the challenges pertained to greenhouse gases emissions. This research paper attributes to the utilization of catalyzed waste vegetable oil as a binder for the production of roofing tiles to replace the conventional construction materials such as clay and cement. A novel methodology of utilizing catalyzed waste oil incorporated with sand and filler was adopted and the innovative product produced is entitled as catalyzed Vege-Roofing tiles that discovered to be economical and environmentally friendly in contrast to the traditional binders. It is believed that an extended heat curing of vegetable oil resulted in a complex oxy-polymerization reaction converting it into a rigid binder. Triplicate prototypes samples were manufactured to optimize the final conditions for the fabrication of catalyzed Vege-Roofing tiles. Optimized conditions were then implemented to produce standard catalyzed Vege-Roofing tiles and these fabricated tiles have shown flexural stress of up to 12 MPa for 18 h of curing. Moreover, these novel tiles were tested for permeability and water absorption according to the ASTM standards and have shown impermeability and remarkably low water absorption. Progressively, the embodied energy and embodied carbon requirements for these tiles found to be 0.64 MJ/kg and 0.327 kg CO2 per equivalent respectively which is quite less in comparison to the traditional binders. Conclusively, environmentally friendly and economic production of tiles, conservation of existing resources and overcoming the issue of waste management are the remarkable outcomes of this research. © 2017 Elsevier Ltd date: 2017 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85011649813&doi=10.1016%2fj.jclepro.2017.01.028&partnerID=40&md5=777dc0a1e93858139f4a314c6ae2e6de id_number: 10.1016/j.jclepro.2017.01.028 full_text_status: none publication: Journal of Cleaner Production volume: 145 pagerange: 250-261 refereed: TRUE issn: 09596526 citation: Nadeem, H. and Habib, N.Z. and Ng, C.A. and Zoorob, S.E. and Mustaffa, Z. and Chee, S.Y. and Younas, M.
