The Saudi Investment Recycling Company (SIRC), a wholly owned subsidiary of the Public Investment Fund in the Kingdom of Saudi Arabia, calls on all local, regional, and international companies specialized in the waste management and recycling sector to register their interest for a potential partnership in developing an integrated waste management and recycling ecosystem for the city of Riyadh. Through these partnerships with qualified companies and consortia, SIRC aims to contribute in diverting 94% of Municipal Solid Waste (MSW) from landfills by 2035 in line with the national targets of Saudi Green Initiative. Additionally, SIRC emphasizes that the integrated waste management and recycling solution for Riyadh must follow international best practices in the field of waste treatment and recycling, while catering to the local landscape and requirements. The solution will include sorting and recycling stations, waste to energy and alternative fuel (RDF) production plants, as well as composting facilities. The proposed solution will enable the entire MSW value chain, starting from sorting at the source, collection, transportation, treatment, and finally recycling. SIRC, along with the private sector, will develop the solution in accordance with the rules & regulations of the National Center for Waste Management “MWAN”. SIRC invites companies seeking to invest and participate in this endeavor to submit their interest through the SIRC website using the provided link: https://sirc.sa/company-registration-form/
