Public crude oil fields in Wonocolo Sub-district was active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil...

The abundance of microplastics (MP) in the aquatic environment is increasingly disturbing for maritime countries, especially Indonesia, because it has the potential to threaten the health and sustainability of aquatic ecosystems. This review summarized and discussed the distribution of MP...

The abundance of plastic waste is caused by inadequate management. The element of plastic waste consists of crude oil and natural gas that can be reuse as fuel. The conversion technique which can be applied is thermal cracking as known as pyrolysis that combined with a catalyst. The addition of a catalyst can accelerate the process of crude oil formation so that the volume increases and makes the quality better. The pyrolysis can convert waste into oil up to 81% that are consist of paraffin, isopropyl, olefin, naphthal and aromatics so feasible to use as fuel. Keywords: catalyst, crude oil, fuel, plastic waste, pyrolysis.

The present study was undertaken to investigate the removal of 16 polycyclic aromatic hydrocarbons (PAHs) listed as priority pollutants by the US Environmental Protection Agency (USEPA-PAHs) that are found in coal-contaminated soil during simulated in-vessel composting. Contaminated soil (S) was mixed with green waste (W) in the ratios of 3:1, 1:1, and 1:3 under neutral and acidic soil conditions in laboratory-scale composting reactors. The highest removal efficiency of total 16 USEPA-PAHs (71.88%) was observed in S:W ratio of 1:1 and neutral soil treatment with the removal rate constant of 0.0106 day⁻¹. Results found that the S:W ratio significantly influenced the removal of PAHs during composting but not the initial soil pH. The results of this research suggest that composting is a feasible and appropriate technology to remediate soil contaminated by coal-native PAH.
