Humic acids (HA) are organic molecules that play essential roles in improving soil
properties, plant growth, and agronomic parameters. The sources of HA include coal, lignite …

Humic substances (HS), as important environmental components, are essential to soil health
and agricultural sustainability. The usage of low-rank coal (LRC) for energy generation has …

Hydrothermal carbonization (HTC) of raw and anaerobically digested (AD) manure with
either water or whey was studied, with the goal of recovering energy and nutrients …

Humic acids isolated from seven lignite samples from six European coal basins were
characterized using spectral methods and elemental analysis and compared with each …

Simple Summary Despite the wide perception that coal environments are extreme habitats,
they harbor resident microbial communities. Coal-associated habitats, such as coal mine …

1 In this study, humic substances were extracted from lignite of Zarand coalfields, Kerman,
Iran, using a stirred batch reactor. A membrane ultrafiltration system was used to purify …

Difficulties in disposal of fly ash resulting from coal combustion at electric power plants are of
increasing concern. Establishment of vegetation is often an effective means of stabilizing …

The removal of metal ions (Pb, Cd, Zn, and Cu) from spiked aqueous solutions using four
lignite samples (TH2, TH7, MT2, and MT8) of different quality, from different areas in Greece …

Humans are dependent upon soil which supplies food, fuel, chemicals, medicine,
sequesters pollutants, purifies and conveys water, and supports the built environment. In …

The present paper is focused on organic petrology applied to unconventional and
multidisciplinary investigations and is the second part of a two part review that describes the …
