Comprehensive Review on Lipid-based Biomasses as Biodiesel Raw Materials from Ghana

Ghana is a country rich in natural resources, including biodiversity and large water bodies, but it is also plagued by food and energy shortages. Fuel prices are also increasing. Biodiesel made from lipids will attract increasing attention as researchers and experts look for a solution. However, the obvious cheapest option of edible feedstock will be insufficient to meet rising energy and food demand, necessitating the need for a guaranteed feedstock. As a result, this research was conducted to identify lipid-based biomass feedstocks that would be ideal for biodiesel production in Ghana. This research seeks to give current information on the biofuel feedstock currently existing (mostly biodiesel) synthesis from lipid-based biomasses in Ghana. Edible plant oils were the first generation of lipid-based feedstocks, whereas alternative types of feedstocks were identified and reported as the second generation. Non-edible oils, like Jatropha oil, Neem oil, Karanja oil, Nagchampa oil, Calophyllum inophyllum oil, Mahua indica oil, Rubber seed oil, and other non-edible feedstocks are used to make second-generation biodiesels. Vegetable oil waste, industrial wastes and by-products, animal fats, and lipid-derived from microorganisms and insects are also among the 2nd generation feedstocks discussed in this paper. The advantages of 2nd generation feedstocks are the low-cost, high-yielding, and the fact that they do not economically or ethically compete with edible oils (food crops). Nevertheless, all 2nd generation feedstocks are often free fatty acids and having high moisture, which have a significant detrimental impact on the conventional biodiesel synthesis process. As a result, this article contains basic information on processing procedures that can handle 2nd generation feedstocks.
