“…This option produces low-carbon hybrid fuels and allows the gradual decarbonisation of fuels [ 6 , 7 ]. The co-processing has already been pointed to by numerous studies as plausible [ 8 , 9 ], even in the case of waste oils (waste cooking oils or animal fats) [ 10 , 11 ], which is in line with the circular economy action plan (CEAP) of the EU, “Less waste, more value”.…”

Phonolite material has shown to be promising catalyst support for the deoxygenation of triglycerides. In this work, we continue with our previous research by synthesising and testing three acid-treated phonolite-supported Co-Mo, Ni-Mo and Ni-W catalysts for the hydrotreating of atmospheric gas oil and co-processing with rapeseed oil at industrial operating conditions (350–370 °C, WHSV 1–2 h−1, 5.5 MPa) in the continuous regime for more than 270 h. The phonolite-supported catalysts showed hydrotreating activity comparable with commercial catalysts, together with a complete conversion of triglycerides into n-alkanes. During co-processing, the Ni-promoted catalyst showed strong stability, with similar activity previous to the rapeseed oil addition. Our results enable us to evaluate the suitability of phonolite as catalyst support for the development of plausible alternatives to conventional hydrotreating catalysts for the co-processing of middle distillates with vegetable oils.

“…A few studies utilized beef tallow as the feedstock for biodiesel production with different approaches. Dias et al [88] investigated the co-processing of beef tallow and soybean oil in the presence of a heterogeneous Ca catalyst. They discovered that the transesterification of beef tallow produced lower biodiesel yield (61 %) compared to co-processing with soybean oil (75 %) as it could reduce the FFA of beef tallow.…”

Utilization of Dairy Scum Waste as a Feedstock for Biodiesel Production via Different Heating Sources for Catalytic Transesterification

The increasing demand of the world energy consumption has made it necessary to shift energy technologies toward renewable energy sources. The sustainability of feedstock can be maintained when utilizing feedstock from waste sources, such as dairy waste, food waste, and others. Dairy waste is one of the cheapest sources available. The compositions of dairy waste scum, including free fatty acids (8–10 %), triglycerides (more than 80 % in dry bases), and fats around 60 %, which have the potential to be used as the feedstock for biodiesel production in the presence of certain catalysts. To ensure more sustainability, the catalyst should be derived from waste (e.g., eggshells and cow bones) that consists of calcium oxide, which can then be used to catalyze the transesterification of dairy waste. This review emphasizes the current production of dairy waste globally and the potential of the waste and other types of organic waste as feedstock for biodiesel production, as well as determines the optimum reaction conditions for high‐quality biodiesel production.

“…However, heterogeneous catalysts for biodiesel production can be more cost-effective when the catalyst is derived from waste and discards [6,37]. Agricultural waste is a carbon source which is used as a precursor for catalyst synthesis, according to several studies [38][39][40]. Considering waste material as a source for catalyst synthesis with active metal modification can thus be viewed as a viable strategy for producing cost-effective product biodiesel [41,42].…”
