“…113,114 Non-edible oilseed plants are generally found on wild and undersized terrain making them a strong competitor for overcoming the barrier of arable land competition. [115][116][117][118] On the other hand, agricultural wastes, being rich in carbohydrates, minerals, and proteins, 119,120 also have the potential to stimulate the efficient growth of microorganisms that might be exploited as feedstock in the production of third and fourth-generation biofuels. 121 Sub-Saharan countries often dispose of the enormous volumes of lignocellulosic residues generated by agricultural activities in an unsustainable manner by either burning them or dumping them in landfills, both of which are very detrimental to the environment.…”

Given the benefits of biofuels over conventional fuels, there is concern that widespread production of biofuels from edible feedstocks to meet demand will lead to food insecurity and other socioeconomic challenges. Thus, the goal of this research is to look into the techno‐economic potential of non‐edible oilseed plants and agricultural wastes as primary feedstocks for biofuel production in Africa. The inability of biofuel to cope in the fuel market has been demonstrated to be due to the high production costs, which limit profitability because the end price is heavily influenced by that of conventional fuel. However, the high production costs are entirely due not only to components such as feedstock, conversion processes, and infrastructure but also to a lack of techno‐economic assessment (TEA). African biofuel production can be competitively industrialized through the adoption of strong supportive policies and programs. Adoption of these policies and programs is critical for capitalizing on the benefits of non‐edible feedstocks in biofuel production while also boosting rural development through job creation. Techno‐economic assessment of conversion processes and infrastructure is recommended to provide a clear picture of the techno‐economic aspects, serving as a blueprint for the design of biofuel production facilities. Further, TEA has been shown to be a useful tool in the development process of new technologies aimed at lowering overall production costs and making biofuel more affordable. The combination of TEA and enabling policies and programs will increase the price competitiveness of biofuels, allowing them to capture a sizable share of the fuel market.

“…In this study, four kinds of agricultural wastes (XS: oilseed rape straw/OS, rice straw/RS, wheat straw/WS, and corn stover/CS) liquefied polyols (P‐XS) were used to react with isocyanate for preparing bio‐based polyurethane foams (XSPU: OSPU, RSPU, WSPU, and CSPU). The utilization of these four agricultural wastes to prepare PU foams could not only contribute to treat with the ecological and environmental backlashes they created but also provide renewable resources to replace fossil resources for the production of necessities 32 . Another kind of petroleum polyol‐based PU foam was prepared as the comparing neat foam as well.…”

Bio-based polyurethane foam has attracted growing attention worldwide due to its advantages of environmental friendliness and wide range of raw materials. However, the stability and degradation ability of the newly prepared foams need to be further explored for their practical application. Four agricultural wastes (XS: oilseed rape straw/OS, rice straw/RS, wheat straw/WS, and corn stover/CS) liquefied polyols were used to replace petroleum polyol for preparing polyurethane foams (XSPU). These bio-based foams were investigated by Thermogravimetric analysis (TGA), Fourier transformed infrared spectroscopy (FTIR), two dimensional correlate infrared spectroscopy (2D-COS IR), water immersion test, soil burying test, and compression test to confirm their stability and degradation properties for applications. XSPU foams displayed excellent thermal stability with heating till to 240 C, appeared to change less than 0.3% in dry weight and contain more hydrogen bonds after immersing in water at 20 C for 14 days. The degradability of XSPU foams was significantly higher than that of petroleum polyol-based PU foam as their soft segments were easier to be decomposed, where the weight loss of XSPU was up to 46.7% after burying in the soil at 23 C and 50% relative humidity for 250 days. The compression recovery ability of these bio-based foams could reach approximately 98.2% after 1 $ 3 times of compression test. Generally, XSPU foams displayed excellent thermal stability, stability in water, degradability in soil, and elastic ability, which showed potential application in fields of insulation, degradable plastic, and elastomer.
