Abstract(s)
In recent years, a collective effort is made in search of alternative forms of energy through renewable
and more friendly to the environment sources, currently, about 80% of the world consumption of energy
comes from fossil fuels. The environmental problems associated with the use of these non-renewable
fuels include air pollution and global warming, moreover, the uncertain price of a barrel of oil in the
current economy also causes economic problems in its dependence. Thus, due to these problems in the
dependence on fossil fuels for industry, transport and domestic purposes, research on alternative energy
sources has become ever more common [1]. In this scenario, biodiesel presents itself as a renewable fuel,
environmentally friendly and with similar characteristics to common diesel.
According to [2] in 2020, global biodiesel production reached 46.45 million tons, with biodiesel from
waste cooking oils (WCO) constituting approximately 10% of this total, with Europe accounting for
approximately 33% and Brazil 12% of global production. The cost of conventional biodiesel production
is higher than the production of diesel from petroleum, since it is produced mainly from high quality
virgin oils, it is estimated that 70 to 80% of the total cost of biodiesel production is associated with the
cost of their raw materials [3]. With this perspective, biodiesel production from WCO has become an
economic opportunity and an environmental strategy to help address global renewable energy
challenges and contribute to a sustainable society [4]. Oil with hours of frying at high temperatures
results in the loss of its edible properties and nutritional value, the disposal of used cooking oil remains
an issue due to its environmental and human health threats, countries are now imposing penalties and
restrictions on the disposal of this cooking waste in drainage systems and/or natural water bodies [5].
In this scenario, the collection and destination of these oils for the production of a value-added and
environmentally friendly biofuel presents itself as an opportunity to be investigated
