In the heart of Morocco, where the argan tree thrives, a treasure trove of untapped potential lies in the by-products of argan oil production. Otmane Hallouch, a researcher from the Biotechnology, Analytical Sciences and Quality Control Team at the University Ibn Zohr, Agadir, Morocco, has been delving into the world of argan by-products, and his findings, published in the Journal of Agriculture and Food Research, are set to revolutionize the industry.
The argan oil industry is booming, with an annual production of approximately 4,450 tons. However, this success story comes with a significant environmental cost. For every 100 kg of dried argan fruit, a mere 6 kg of kernels are used to produce argan oil, leaving behind a staggering 97% of the fruit as by-products. These by-products, which include the pulp, nutshell, and press cake, are often discarded as waste, leading to environmental degradation and lost economic opportunities.
Hallouch’s research sheds light on the potential of these by-products, particularly the nutshell, which is emerging as a sustainable resource with immense value. “The valorization of argan nutshell is one of the most advanced and promising areas,” Hallouch states, highlighting the nutshell’s potential in the production of CO2-based activated charcoal and biofuels. This not only enhances the profitability of the argan oil sector but also promotes sustainability by reducing waste and carbon emissions.
The implications for the energy sector are profound. As the world shifts towards renewable energy sources, the demand for biofuels and sustainable materials is on the rise. Argan nutshells, with their high carbon content and abundance, could be a game-changer. The production of CO2-based activated charcoal from argan nutshells, for instance, could provide a sustainable alternative to traditional charcoal, reducing deforestation and carbon emissions.
Moreover, the potential of argan by-products extends beyond the energy sector. Hallouch’s research also explores their applications in the fields of bioenergy, nanomaterials, pharmaceuticals, and cosmetics. This opens up a world of possibilities for the argan oil industry, transforming it from a single-product sector to a multi-faceted industry with diverse revenue streams.
The future of the argan oil industry is bright, and it’s not just about the oil anymore. As Hallouch’s research shows, the true value of the argan tree lies in its by-products. By harnessing this potential, the industry can achieve sustainability, profitability, and environmental stewardship, setting a benchmark for other agricultural sectors worldwide.
