In the current environmental scenario, proposal of alternatives for petroleum-based products has considerably increased, with aim looking bioproducts interesting properties such as biodegradability, sustainability and efficiency, among others. this sense, role biolubricants is promising, offering a wide range possibilities through different methods operating conditions. Specifically, double transesterification could be suitable process in biorefinery context. The work was to produce biolubricant methanol neopentyl glycol (NPG) under reaction conditions by using homogeneous catalysis (sodium methoxide). Different catalyst concentrations, other changes (temperature ranging between 100 140 °C NPG/FAME ratios 0.5 2), were used, obtaining high conversion values (96%) final product viscosity (20.7 cSt), which allows its use engine oil (SAE 5W). conclusion, biodiesel production feasible catalysis, proving feasibility at laboratory scale. Further studies, including heterogeneous catalysts, well implementation semi-industrial scale, are recommended.

Since private cars and vans accounted for more than 25% of global oil consumption about 10% energy-related CO2 emissions in 2022, increasing the share electric vehicle (EV) ownership is considered an important solution reducing emissions. At same time, entails certain economic losses those countries whose exports are largely covered by trade. The explosive growth EV segment over past 15 years has given rise to overly optimistic forecasts penetration 2050. One major obstacles such a development scenario limited availability resources, especially critical materials. This paper proposes mathematical model predict fleet based on materials as lithium, one key elements battery production. proposed three distinctive features. First, it shows that classical logistic function, due specificity its structure, cannot correctly describe market saturation case using resources with serves. Second, even use special multiplier describes process taking into account depletion (finiteness) used resource does not obtain satisfactory results because “high speed” this resource. Third, analytical final indicates point time at which changes rate occur. latter situation allows us determine tracking saturation, similar actually occurring. We believe can also be validated estimate production wind turbines rare earth neodymium dysprosium (for powerful permanent magnets turbines). These suggest need oil-exporting technologically diversify their economies minimize transition low-carbon economy.

Concerns about climate change are a hot topic in the current debate sustainable future, and despite more than 30 years of international conferences, including Intergovernmental Panel on Climate Change (IPCC) United Nations Conference (COP), annual usage amount fossil fuel-based energy sources has remained largely unchanged, green transition to carbon-free system is progressing at much slower pace anticipated. This paper presents an original approach that consists addressing transition’s dilemmas by analyzing complex interplay strongly interwoven forces hindering rapid adoption so-called scrutinized from three-fold perspective: socio-psychological; political–strategic territorial; technological. Moreover, these ranked according magnitude their impact anticipated green, it estimated logistic fit extrapolation total share contribution low-carbon might reach maximum 25% among all 2050. A final picture presented, summarizing how involved acting upon expected as well consequences.
