Recycling of Waste Oils: Technology and Application

Dear Colleagues,

We are currently facing important challenges in many aspects of our life, from food demand to energy production and from exploitability of resources to climate change. We can observe as general trend in modern industry in the reconversion of existing processes and the design of new ones on the basis of the circular economy concept. In such a vision, wastes upon production can be considered raw materials for other processes. In order to produce sensible advances toward a global circular economy, the scientific research and the consequent technological advances must be directed on the concept of recycling of byproducts in a sustainable way. In such a panorama, waste oils represent a major challenge. In fact, they are produced worldwide in huge amounts and they are responsible for many environmental issues if not properly disposed of. At the same time, their chemical composition, constituting a mixture of fatty acids, makes them an important raw material for many industrial processes. For all these reasons, the recycling of waste oils is currently mandatory in many countries and is matter of discussion in many others.

This Special Issue entitled “Recycling of Waste Oils: Technology and Application” is aimed to cover the current advances on waste oils recycling in terms of technological solutions, sustainability aspects, and application of waste oils as raw material. Topics include but are not limited to:

- Waste oils production and disposal.

- Vegetal used oils recycling.

- Mineral oils recycling.

- Technological advances in waste oil recycling.

- Economic, marketing, and legislative aspects related with waste oils’ life cycle.
