Avocado is a dicotyledonous plant that belongs to the flowering plant family Lauraceae, native to Mexico and Central America but now grown in many different regions across the globe. Its fruit is widely consumed in Nigeria. It is not only a nutritious food item but also a source of valuable raw materials.
Avocado pit, also known as an avocado seed, is a light brown seed found in the middle of an avocado, often discarded, and it is a treasure trove of potential applications. In this article, we will explore the possibilities of utilizing avocado pit as a raw material in Nigeria and its various applications.

Availability and Potential
Nigeria is one of the largest producers of avocados in Africa, with the fruit being widely cultivated in states like Osun, Oyo, and Ekiti (National Bureau of Statistics, 2020). With millions of avocado fruits being consumed annually, the potential for harnessing the pit as a raw material is enormous. The avocado pit is a rich source of nutrients, including protein, fiber, and healthy fats, making it an ideal raw material for various industrial applications.

Applications of Avocado Pit
Bioplastics: Avocado pit yields various bioplastics, including Polyhydroxyalkanoates (PHA), Polylactic Acid (PLA), and Cellulose Acetate (Koller et al., 2017; Datta et al., 2016; Kamide et al., 2017). These bioplastics can be used in packaging, textiles, and other industries.
Oil Extraction: Avocado pit contains a significant amount of oil, which can be extracted and used in various industries, including cosmetics, pharmaceuticals, and food processing (Ogunsina et al., 2011).
Animal Feed: The pit can be processed into animal feed, providing a nutritious supplement for livestock, particularly poultry and swine (Adeyeye et al., 2015).
Compost: Avocado pits can be composted and used as organic fertilizer, reducing the need for synthetic fertilizers and promoting sustainable agriculture practices (Oyedele et al., 2015).
Bioactive Compounds: The pit contains bioactive compounds, including flavonoids, alkaloids, and saponins, which have been shown to possess antimicrobial, antioxidant, and anti-inflammatory properties (Adewole et al., 2017).
Activated Carbon: Avocado pit can be converted into activated carbon, a valuable material used in water filtration, air purification, and industrial processes (Adebayo et al., 2018).
Natural dye: Avocado pits can be used as a natural dye for fabrics, paper, and other materials. Their anthocyanins have been extracted to make natural dyes (Kusumastuti et al. 2023)
Challenges and Opportunities
Despite the potential of avocado pit as a raw material, there are challenges to be addressed. These include:
Lack of Awareness: Many Nigerians are unaware of the potential uses of avocado pits, leading to its disposal as waste.
Limited Processing Infrastructure: The lack of processing facilities and equipment hinders the extraction and utilization of avocado pit oil and other valuable compounds.
Research and Development: Further research is needed to fully explore the potential applications of avocado pit and to develop efficient processing methods.
In conclusion, the avocado pit is a valuable raw material in Nigeria, offering numerous applications across various industries. Efforts should be made to raise awareness about the potential uses of avocado pit, invest in processing infrastructure, and conduct further research to unlock its full potential. By doing so, Nigeria can reduce waste, promote sustainable development, and create new economic opportunities.
