“…This will be efficient for reducing the emission of pollutants, especially SPM and SO x . Although the potential of biodiesel production from edible oilseeds is estimated at 721 million liters [56], oilseeds are consumed only in the food sector in Iran. Also, using poultry slaughter waste to produce biodiesel can solve the problem of disposal.…”

Biodiesel is a kind of biofuels that can be mixed with diesel and used as fuel. Selecting cheap and available feedstock is a prominent step in producing biodiesel economically. This paper presents the pros and cons of biodiesel and its production methods. The diesel demand is significantly high in Iran, especially in the transportation sector; On the other hand, the amount of produced waste is significant in chicken slaughterhouses. Considering this type of feedstock as a source to produce biodiesel not only can reduce the associated environmental problems, but also can supply some of the diesel needs. Hence, this paper also estimates biodiesel production potential from poultry slaughter waste and its cost. Based on the results, 736 kilotonnes of poultry slaughter waste is produced annually in Iran, which can be used as feedstock to produce 112 million liters of biodiesel by transesterification process with the production cost of around 14,277 rial/liter; i.e. 30% of diesel demand in the transportation sector can be supplied by B2 (98% diesel and 2% biodiesel) or diesel demand growth in this sector converted to B20 to increase economical and environmental sustainability.

The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, reduce harmful gas emissions, support the sustainability of natural resources, including water, and minimize the amount of waste in landfills, thus reducing environmental degradation. In this paper, the conversion of agricultural wastes into biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, and bio-oil is reviewed, with special emphasis on primary and secondary agricultural residues as substrates. Some novel approaches are mentioned that offer opportunities to increase the efficiency of waste valorization, e.g., hybrid systems. In addition to physical, chemical, and biological pretreatment of waste, some combined methods to mitigate the negative effects of various recalcitrant compounds on waste processing (alkali-assisted thermal pretreatment, thermal hydrolysis pretreatment, and alkali pretreatment combined with bioaugmentation) are evaluated. In addition, the production of volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, and selected platform chemicals from lignocellulosic waste is described. Finally, the potential uses of biofuels and other recovered products are discussed.

“…Second, there are technological and market barriers for using bioenergy in transportation 89,90 , which make it difficult to equip CCS on vehicles 91 . We considered a scenario where biomass produces bioethanol with a 16% of energy loss in production 92 to substitute vehicle oils without CCS. Third, we considered a scenario, where the efficiency of energy conversion was increased from 27.8% for BECCS power plants in our central case to 47.5% in biorefinery plants 43 , but 15% of CO2 released at a high purity during the fermentation process can be captured 43 .…”

The potential of mitigation actions to limit global warming within 2 °C1 might rely on the abundant supply of biomass for large-scale bioenergy with carbon capture and storage (BECCS) that is assumed to scale up significantly in the future 2-5 . However, the detrimental effects of climate change on crop yields may reduce the capacity of BECCS and threaten food security 6-8 , thus creating an unrecognized positive feedback loop on global warming. We quantified the strength of this feedback by implementing the responses of crop yields to increases in growingseason temperature, atmospheric CO2 concentration and intensity of nitrogen (N) fertilization in a compact Earth system model 9 . Exceeding a threshold of climate change would cause transformative changes in social-ecological systems by jeopardizing climate stability and threatening food security. If global mitigation alongside large-scale BECCS is delayed to 2060 when global warming exceeds ~2.5 °C, then the yields of agricultural residues for BECCS would be too low to meet the Paris goal of 2 °C by 2200. This risk of failure is amplified by the sustained demand for food, leading to an expansion of cropland or intensification of N fertilization to compensate for climate-induced yield losses. Our findings thereby reinforce the urgency of early mitigation, preferably by 2040, to avoid irreversible climate change and serious food crises unless other negative-emission technologies become available in the near future to compensate for the reduced capacity of BECCS.
