With growing concerns over climate change and resource depletion, the global search for sustainable materials has never been more urgent. While Africa has long been seen as a source of raw materials, the continent is now taking active steps to shape the future of renewable resources. From lithium extraction to large-scale recycling and bio-based material development, Africa is playing a vital role in the transition towards sustainability.
According to the International Energy Agency (IEA), global material consumption is projected to double by 2060, reaching 167 gigatonnes annually. The extraction of raw materials such as metals, fossil fuels, and biomass currently accounts for 50% of global carbon dioxide emissions, as reported by the United Nations Environment Programme (UNEP). Meanwhile, the Ellen MacArthur Foundation estimates that transitioning to a circular economy could reduce material-related emissions by up to 45% by 2050, highlighting the necessity of renewable materials in climate mitigation strategies.

The Energy Information Administration’s (EIA) International Energy Outlook projects that global energy consumption will increase by 34% between 2022 and 2050, outpacing advances in energy efficiency. Factors such as global population growth, increased regional manufacturing, and higher living standards contribute to rising consumption, leading to a projected 15% increase in global carbon dioxide emissions from energy by 2050.
The World Economic Forum reports that the global bioeconomy, which includes renewable materials, is valued at approximately $5 trillion. While Europe and North America lead the charge, Asia and Africa are rapidly increasing their footprint. According to the African Circular Economy Alliance (ACEA), Africa’s transition to renewable materials has the potential to inject an additional $4.5 trillion into its economy by 2030, driving employment, reducing waste, and mitigating environmental impact.
Africa’s Lithium Boom: A Renewable Energy Game-Changer
One of Africa’s most significant contributions to the global search for renewable materials is its vast lithium reserves. Lithium, a critical component in battery production for electric vehicles (EVs) and renewable energy storage, has made Africa a focal point for international investment. The continent holds an estimated 4.9 million metric tonnes of lithium reserves, with major deposits in Zimbabwe, the Democratic Republic of Congo, Mali, and Namibia.
Zimbabwe, home to one of the world’s largest lithium reserves, is rapidly becoming a key supplier of the mineral. The country produced approximately 1,200 metric tonnes of lithium in 2022, with projections to exceed 20,000 metric tonnes by 2025 due to foreign investments from China, the US, and Europe. The Bikita, Arcadia, and Zulu lithium mines are among the most prominent, attracting billions in funding. Meanwhile, Mali’s Goulamina lithium project, backed by Australia’s Firefinch Limited, is set to become a major global producer, contributing to the shift towards sustainable energy solutions.
As demand for electric vehicles surges, Africa’s lithium industry is expected to play a crucial role in reducing global reliance on fossil fuels. According to BloombergNEF, the global lithium-ion battery market is projected to reach $400 billion by 2030, with Africa poised to be a major supplier of raw materials. However, concerns over resource exploitation and fair value distribution remain critical. African governments are increasingly pushing for local processing and value addition, ensuring that lithium benefits the continent’s economy rather than merely serving as an export commodity.
The Agricultural Goldmine: Biomaterials and Organic Innovation
Africa’s vast agricultural sector is another frontier for renewable materials. The continent produces significant quantities of agricultural waste, much of which can be repurposed into bio-based alternatives. Over 70 million tonnes of crop residues are generated annually, providing a valuable resource for creating biodegradable packaging, bio-composites, and organic fertilisers.
Countries such as Ghana and Côte d’Ivoire, which together produce over 60% of the world’s cocoa, are exploring ways to repurpose cocoa husks into bioplastics and biofuels. Similarly, Ethiopia and Kenya, two of the largest coffee producers, are developing sustainable alternatives to petroleum-based materials using coffee husks and pulp. The integration of biomaterials into mainstream industries presents an opportunity for Africa to shift from an exporter of raw agricultural commodities to a global leader in sustainable material production.
Industrial Scale-Up: Renewable Construction and Textiles
The construction and textile industries are among the most resource-intensive sectors globally, and Africa is pioneering sustainable alternatives in both fields. Countries such as Rwanda and Ethiopia are investing in green building materials, with Kigali emerging as a hub for bamboo-based construction materials. The International Bamboo and Rattan Organisation (INBAR) notes that Africa’s bamboo industry, valued at over $20 billion, has the potential to revolutionise construction through renewable materials.
In the textile sector, organic cotton, hemp, and recycled polyester are gaining traction. According to the Ethical Fashion Initiative, Africa’s sustainable textile industry is projected to grow by 13% annually, driven by eco-conscious fashion brands such as Ghana’s Studio 189 and South Africa’s Sealand Gear. These efforts align with the global push for sustainable fashion, a $1.5 trillion industry expected to transition towards 50% renewable materials by 2030.
The Future of Africa’s Renewable Material Economy
As the world pivots towards sustainability, Africa is proving that it is not just a participant but a leader in the search for renewable materials. With its rich natural resources, innovative entrepreneurship, and increasing policy support, the continent is set to play a crucial role in shaping the future of sustainable industries. If leveraged strategically, Africa’s contributions could redefine global supply chains, making sustainability not just an aspiration but a reality.
