Manufacturing expert Samuel Olabode Afolabi, a PhD researcher at the Manufacturability-Driven Design Lab (MDDL) at Texas A&M University, USA, has revolutionised sustainable manufacturing. He is determined to address the pressing environmental challenges associated with traditional semiconductor manufacturing. His recent review, “Exploring the Environmental Impact of Chip Manufacturing: Challenges and Opportunities in Additive Manufacturing Methods,” was born out of his certification training in “Semiconductor Fabrication 101,” a joint-sponsored programme from Purdue University, the University of Texas at Austin, and Intel.
Afolabi’s review meticulously outlines the significant challenges faced by traditional semiconductor manufacturing processes, including substantial resource consumption, chemical pollution, energy usage, and waste generation. These issues not only compromise environmental sustainability but also pose risks to human health, highlighting the urgent need for innovative approaches to mitigate these impacts. The exploration of additive manufacturing (AM) methods as promising alternatives has opened new vistas for addressing these environmental challenges. AM’s potential to revolutionise chip production through reduced material waste, lower energy consumption, and minimised chemical pollution aligns with the broader goals of sustainable development.
The studies reviewed underscore the importance of advancing AM technologies in electronic fabrications, showcasing successful applications in semiconductor packaging. These advancements not only demonstrate AM’s capability to enhance manufacturing efficiency and flexibility but also its role in fostering a more sustainable electronics industry. However, the total transition to additive manufacturing in mainstream chip production is not without its challenges. Issues such as material limitations, precision and resolution, and process control and repeatability must be addressed to fully leverage AM’s benefits. Moreover, the integration of AM into the established semiconductor manufacturing ecosystem presents logistical and technical hurdles that necessitate collaborative efforts among industry stakeholders.
Considering these findings, it becomes evident that while additive manufacturing offers a viable pathway towards environmentally sustainable chip production, its adoption requires concerted efforts from academia, industry, and policymakers. Encouraging research and development, investing in technology refinement, and fostering industry-wide standards and collaboration will be key to overcoming the challenges identified. Moving forward, the semiconductor industry stands on the brink of a significant transformation, poised to embrace additive manufacturing methods that align technological innovation with environmental stewardship. This literature review not only highlights the urgency of addressing the environmental impacts of chip manufacturing but also the potential of additive manufacturing to chart a sustainable course for the future of the semiconductor industry.
Afolabi has to his record several publications in reputable international journals. Notable among the publications is the “Development of a Low-Cost Polyurethane Waste Shredding Machine.” This paper presents the design and testing of a small-scale foam shredding machine that is affordable and efficient for both large and small businesses. By enabling small-scale industries to recycle polyurethane foam waste, this machine helps reduce the environmental impact of foam disposal. The shredded foam can be reused in various applications, turning waste into valuable products and promoting a circular economy. This aligns with global sustainability goals and reduces the carbon footprint associated with the production and disposal of polyurethane foams. The project can serve as a practical example for educational institutions and vocational training centres, providing hands-on learning opportunities in mechanical design, manufacturing, and sustainable practices.
This innovation not only addresses the environmental issue of foam waste but also reduces operational costs, making the recycling process more economically viable and accessible. These machines are designed to be cost-effective and accessible to small-scale and cottage industries. This opens new business opportunities for entrepreneurs and small businesses, allowing them to enter the recycling industry without the need for significant capital investment in large-scale industrial equipment. By promoting the adoption of these technologies, industries can enhance their environmental performance, conserve resources, and ensure economic viability, ultimately contributing to a more sustainable industrial ecosystem.
