Every year, the increasing human population has contributed to abundance of Municipal Solid Waste (MSW) at designated landfills, especially in Malaysia. On other hand, iron and steel industry, a high demand for production caused an increase CO2 production, which would, unfortunately, contribute global warming. Therefore, sustainable solutions are needed avoid this environmental crisis from worsening. This study employed effective approach, utilizing low-grade ore Pahang produce by using MSW-derived biochar as alternative coal reductant energy source. project aims mechanism solid-solid reduction reaction with carbon. MSW was collected prepared before slow pyrolysis obtain biochar. Iron characterized X-Ray Fluorescence (XRF) elemental composition determination Diffraction (XRD) observe presence mineral phases. In research, conducted 900? residence times 1 hour, 3 hours, 5 hours. From research that been conducted, temperature time were found influence composition, degree, phase transformation iron. ABSTRAK: Setiap tahun, peningkatan populasi manusia telah menyumbang kepada kelimpahan Sisa Pepejal Perbandaran di tapak pelupusan yang ditetapkan, terutamanya Manakala dalam industri besi, permintaan tinggi terhadap pengeluaran keluli menyebabkan karbon dioksida, malangnya pemanasan global. Oleh itu, penyelesaian mampan diperlukan untuk mengelakkan krisis alam sekitar ini menjadi lebih buruk. Dalam kajian ini, pendekatan berkesan digunakan dengan memanfaatkan bijih besi gred rendah pembuatan menggunakan arang dihasilkan daripada sebagai alternatif batu bahan agen penurunan serta sumber tenaga. Tujuan projek adalah mengkaji mekanisma tindak balas besi. dikumpulkan dan disediakan sebelum menjalani proses pirolisis mendapatkan MSW. Bijih dianalisa Fluoresens penentuan komposisi unsur Penghabluran memperoleh fasa mineral. penyelidikan eksperimen dijalankan pada suhu masa selama jam, jam jam. Berdasarkan dijalankan, didapati mempengaruhi tahap

This study investigates the viability and sustainability of proposed landfill sites based on uncapacitated facility location problem framework utilising SmartPLS4 Structural Equation Modelling. Investigating Cape Coast Metropolis, a stratified sampling method selected 400 samples out which 320 valid respondents were used as basis for analysis. Through statistical analysis, significant correlations identified among community acceptance, environmental impact, accessibility, site sustainability, operational efficiency. However, no correlation was found between economic sustainability. Furthermore, indirect mediation pathway from efficiency to via accessibility also statistically insignificant. Employing use approach in studying application framework, deepens understanding dynamics. research contributes sciences by providing insights into management strategies emphasising importance engagement performance achieving sustainable outcomes. Future could refine model including additional variables like technological advancements regulatory frameworks, conducting longitudinal studies track dynamics over time, undertaking comparative across different geographical regions. provide approaches’ applicability. Interdisciplinary collaborations are recommended address multifaceted challenges
