“…lipase-catalyzed transesterification, is restricted by the rigorous reaction conditions and enzyme activity loss, and hence it is not used in large-scale commercial biodiesel production facilities. As a result, most biodiesel production plants use homogeneous alkali catalysts (sodium or potassium hydroxides, carbonates or alkoxides) since the application of these catalysts is comparatively cost-effective over the currently-available (eco-friendly) heterogeneous catalysts [16,26].…”

The environmental sustainability of second-generation biodiesel (used-cooking-oil) was examined, at industrial-scale, in Greece. The total carbon and environmental footprint per tonne of biodiesel production was ~0.55t CO 2 eq (i.e. ~14g CO 2 eq/MJ) and 58.37Pt, respectively. This is ~40% lower compared to first-generation biodiesel, an order of magnitude lower than the third-generation (microalgae), since the latter is not a fully-fledged technology yet. A threefold reduction in environmental impacts was observed compared to petrodiesel. Environmental hotspots include energy inputs to drive the process, followed by methanol (CH 3 OH) and potassium methoxide (CH 3 KO) consumption. Glycerol (C 3 H 8 O 3 ) and potassium sulfate (K 2 SO 4 ), both process co-products, resulted to avoided environmental burdens. Furthermore, used-cooking-oil valorisation for biodiesel production can address water pollution concerns from its disposal to the sewage system. The total distance and means of transport were found to influence the system's environmental sustainability. Strong incentives for used-cooking-oil recycling, widespread collection systems, and biodiesel supply chain optimization are still pending in Greece, Europe, and further afield. Given its overall low environmental footprint and capability to be produced at commercial scales, the second-generation biodiesel, which currently represents 15% of the biodiesel market in Greece, could act as a stepping-stone in decarbonizing Europe's transport sector and improving supply and energy security.

“…The production of biodiesel from cooking oil, via a base-catalyzed ester hydrolysis, using borosilicate glass catalysts has been demonstrated by Vadery et al , who found that the actual catalyst was Na 2 SiO 3 . 119 Similar work by Foroutan showed that waste glass could also be used as the catalyst for converting waste chicken fat in to biodiesel. 120 In both studies the glass had to be treated with NaOH to become an active catalyst.…”
