Remediation of Petroleum Contaminated Soils
Due to the development of the petroleum industrial, numerous petroleum pollutants are discharged into the soil, destroying the structure and properties of the soil, and even endangering the health of plants and humans. Microbial remediation and combined microbial methods remediation of petroleum-contaminated soil are currently recognized remediation technologies, which have the advantages of no secondary pollution, low cost and convenient operation. This entry includes the sources and composition of petroleum pollutants and their harm to soil, plants and humans. Subsequently, the focus is on the mechanism of microbial method and combined microbial methods to degrade petroleum pollutants. Finally, the challenges of the current combined microbial methods are pointed out.

Shale Oil Occurrence Mechanisms
Shale oil resources are important supplements for the gradually decreasing oil production from conventional reservoirs. The exploitation and development of shale oil have achieved considerable progress, the commercial extraction of hydrocarbons from shales is still difficult, especially in the lacustrine sedimentary basins of China.

Snap-Off during Imbibition in Porous Media
The phenomenon of snap-off during imbibition in porous media, a fundamental two-phase fluid flow phenomenon, plays a crucial role in both crude oil production and carbon dioxide (CO2) utilization and storage. In porous media where two phases coexist, the instability of the phase interface may give rise to various displacement phenomena, including pore–body filling, piston-like displacement, and snap-off. Snap-off, characterized by the generation of discrete liquid droplets or gas bubbles, assumes paramount significance.

Technological and Legislative Impacts on Automotive Sector Development
Land transport activities play an essential role within our society. At the same time, these activities generate directly huge amounts of pollutants due to vehicle operation, and indirectly, more pollution due to vehicle production and recycling as well as a significant consumption of energetic resources and raw materials. Looking back into the cars history, one can notice how their technological development was correlated with the socio-economic, environmental, and health context, and has paved the way for new policies and strategies for exploiting the available energy sources and materials with respect to the current automotive regulations.

Waste Cooking Oil for Biofuel in India
Waste or used cooking oil (WCO/UCO) is a common source of trans fat consumed by Indians, leading to many non-communicable diseases like diabetes, hypertension, cardiovascular diseases, stroke, cancer, etc. In fact, out of 230 million MT of edible oil consumption, India is currently capable of producing only 3 million MT of biodiesel. Moreover, with the increased emphasis on the circular economy to improve rural employment opportunities, India should adopt a complete exergy analysis of biodiesel production from WCO.

Waste Plastic Thermal Pyrolysis
Pyrolysis is one of the most popular thermo-chemical treatment (TCT) methods known today. This is due to their immense impacts on the environment and their operational output. The significant role of pyrolysis with waste plastics as feedstock is trending. Most of these waste plastics which include high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene terephthalate (PET) and polystyrene (PS), have continued to render our environment, our health and oceans in deplorable conditions. This entry presents an assurance into the current findings of waste plastic thermal pyrolysis (WPTP) and revealed some common research gaps and misconceptions surrounding this field.
