Controlling organic waste is a growing challenge worldwide, with rising concerns over environmental pollution and resource decline. Microbial organic waste bioconversion is one solution that offer promise by harnessing oleaginous microorganisms to convert agricultural and domestic waste into valuable industrial bioproducts. This approach contributes to industrial growth through the production of bio-based chemicals, biodegradable polymers, industrial enzymes, and functional food ingredients, serving as a sustainable alternative to traditional waste disposal methods (Chopra et al., 2020).

Nigeria can reduce its reliance on imported feedstock and enhance economic diversification by leveraging microbial bioconversion. This aligns with the mandate of the Raw Materials Research and Development Council (RMRDC) to foster industrial advancement through the optimal utilization of indigenous raw materials.
Industrial Applications of Microbial Organic Waste Bioconversion
- Bio-Based Chemicals and Surfactants
Microbial lipids obtained from organic waste serve as raw materials for bio-based chemicals, including biodegradable surfactants used in detergents, cosmetics, and pharmaceuticals. These alternatives present significant environmental benefits over petroleum-based products (Schmidt, 2015).” - Functional Food and Nutraceuticals
Essential fatty acids such as omega-3 and omega-6 are components of certain microbial oils derived from organic waste fermentation, offering sustainable alternatives for the nutraceutical and functional food industries (Cortés-Peña et al., 2023). - Biodegradable Polymers and Bioplastics
The synthesis of bioplastics from microbial lipids provides an innovative solution to plastic pollution, offering sustainable alternatives to traditional petroleum-based plastics while reducing environmental impact (Masri et al., 2019). - Industrial Enzymes and Pharmaceuticals
Bioactive compounds with pharmaceutical applications, such as biosurfactants, antimicrobial agents, and lipid-based drug carriers, can be produced by engineering oleaginous microorganisms, providing new potential for drug formulation and delivery (Schmidt, 2015).
Sustainability and the Role of Raw Materials Research
The RMRDC plays a crucial role in promoting the industrial utilization of indigenous raw materials, including organic waste. Microbial organic waste bioconversion has reduced environmental impact compared to traditional processing methods as shown by Life Cycle Assessment (LCA) studies. The carbon emissions from microbial oil production are significantly lower than palm and peanut oil, while being similar to those from rapeseed and sunflower oil (Masri et al., 2019; Schmidt, 2015).
However, research efforts must focus on optimizing microbial strains, improving lipid extraction techniques, and developing efficient biorefinery models, to make microbial bioprocessing economically viable. Embracing microbial agricultural waste bioconversion into Nigeria’s industrial sector can foster resource efficiency and reinforce a circular economy (Chopra et al., 2020).
Conclusion
Microbial organic waste bioconversion offers a strategic option for Nigeria’s industrial sector. The country can bolster its position in the global bio-based economy by integrating these technologies into subsisting industrial frameworks and utilizing locally available waste materials. The RMRDC’s continued support for research and policy development in this field will be pivotal for maximizing industrial benefits. Increasing microbial bioprocessing via investments in research, technology, and infrastructure will enhance economic diversification, drive sustainability, and promote optimal utilization of Nigeria’s abundant raw materials.
