Africa's agricultural sector, a vital part of the continent's economy, faces a significant challenge in the form of food waste, with nearly one-third of output being lost annually. The potential of this waste, however, is being explored in the realm of sustainable energy through the conversion of biomass waste into hard carbon for sodium-ion batteries. Compared to lithium-ion batteries, sodium-ion batteries offer a more sustainable and cost-effective alternative due to the abundance of sodium resources. Zineb Kassab's research at University Mohammed VI Polytechnic focuses on utilizing agricultural waste for hard carbon production, emphasizing the environmental and economic benefits of this approach. By repurposing lignocellulosic biomass through pyrolysis, the waste is transformed into a valuable resource for energy storage. The process involves several steps, including pre-treatment and post-treatment to refine the carbon structure for battery use. Kassab's work highlights the environmental advantages of using bio-waste, such as reducing CO2 emissions and promoting a circular economy. Despite challenges in scaling up this technology, particularly in ensuring material consistency and energy efficiency, Kassab sees an opportunity for Africa, including Morocco, to lead in sustainable battery production by capitalizing on the abundance of agricultural waste. By creating a closed-loop system that converts waste into high-value materials, this approach not only addresses the issue of food waste but also contributes to a more sustainable and innovative energy sector.
