On the theory of solitons of fluid pressure and solute density in geologic porous media, with applications to shale, clay and sandstone

open access: yes, 2016
In this paper we propose the application of a new model of transients of pore pressure p and solute density \r{ho} in geologic porous media. This model is rooted in the non-linear waves theory, the focus of which is advection and effect of large pressure

Wastewater management strategies for sustained shale gas production

open access: yesEnvironmental Research Letters, 2020
Recent advances in shale gas development have largely outpaced efforts to manage associated waste streams that pose significant environmental risks. Wastewater management presents significant challenges in the Marcellus shale, where increasing fluid ...

Can you take the heat? – Geothermal energy in mining [PDF]

open access: yes, 2014
In 2013, there are less than 20 documented examples of operational geothermal systems on mine sites worldwide. This is surprising, since on remote mine sites, where fuels may have to be shipped in over great distances, heating and cooling from low ...

Cement with the addition of charred fermentation residues [PDF]

open access: yesMATEC Web of Conferences, 2019
This article focuses on the use and disposal of biochar waste from residual and waste biomass. Traditional use of this substance is its addition to arable land to improve its quality. The basic biochar component is a chemically stable carbon, which binds

Experimental investigation of the productivity of a wet separation process of traditional and bio-plastics [PDF]

open access: yes, 2018
The separation process within a mechanical recycling plant plays a major role in the context of the production of high-quality secondary raw materials and the reduction of extensive waste disposal in landfills. Traditional plants for plastic separation
