Abstract This essay considers the multiscalar manifestations of loss and destruction through material-semiotic figure “spent earth,” a toxic waste by-product generated by industrial bleaching crude oils into edible oils. Drawing on two distinct encounters with spent earth in Indonesian palm oil sector, reflects substance's unevenly distributed effects across peoples, places, generations; its as...

In search of a more sustainable society, humanity has been looking to reduce the environmental impacts caused by its various activities. The energy sector corresponds one most impactful activities since energies produced come from fossil fuels, such as oil and coal, which are finite resources.

According to Environmental Protection Agency (EPA) regulations, the use of ultra‐low sulfur diesel (ULSD) has been mandated for all on‐highway transportation diesels since 2006. To comply with the EPA regulations, biodiesel must meet the same ULSD standard for total sulfur which is set at a maximum of 15 ppm. Generally, biodiesel contains lower sulfur than fossil diesel.

Erythromycin production is clearly enhanced by the addition of vegetable oils. However,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. The non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. In this research, sub-fractions of soybeanoil, including le...

Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]
