Oman: Oman's solid waste management entity, Be'ah, has reported progress in its strategy to transition solid waste from landfill disposal to refuse derived fuel (RDF), according to Oman Daily Observer.

In 2023, Be'ah launched initiatives focusing on transforming waste into RDF, electrical and electronic waste and green waste. The company has signed an agreement with Oman Cement Company to provide tyre derived fuel for its energy needs, eventually expanding to include RDF. A memorandum of understanding (MoU) was signed with Oman Cement during Oman Sustainability Week to explore the utilisation of RDF as an additional alternative fuel source, according to the company’s 2023 sustainability report.

Chair of Be’ah, Ahmed al Subhi, said "We take pride in our strategic resource management initiatives, having set ambitious targets for transitioning to a circular economy, including achieving 60% waste utilisation by 2025 and 80% by 2030.”
