<![CDATA[This study explores the development and benefits of sustainable manufacturing processes in Nigeria using locally sourced materials, specifically cassava residues, palm kernel shells, and limestone. Driven by the need to reduce dependency on imported resources, this research addresses economic, environmental, and social impacts associated with conventional manufacturing practices. Results indicate that cassava residues and palm kernel shells demonstrate high compressive and tensile strengths, making them viable alternatives to synthetic materials in structural applications. Limestone, optimized through local sourcing and CO₂ capture technology, proved effective in cement production, reducing carbon emissions by up to 15%. Process optimization, including thermal recovery systems, led to an average energy savings of 25%, while emission reductions across processes averaged 20%. Economic analysis highlighted a 22% reduction in total costs, attributed to savings on transportation and energy, underscoring the financial viability of local resource utilization. The environmental and economic advantages demonstrate sustainable manufacturing’s potential to enhance Nigeria’s resilience to global supply chain disruptions, support local job creation, and align with the country’s climate goals. The study recommends policy support through incentives for sustainable practices, investment in recycling and waste processing infrastructure, and training programs to ensure skilled implementation. Future research should expand these processes to other materials and sectors, integrating advanced monitoring technologies for further efficiencies. These findings provide a foundational approach for Nigeria’s shift towards a sustainable, economically resilient manufacturing sector.]]>
