Pyrolysis of Municipal Sewage Sludge to Investigate Char and Phosphorous Yield together with Heavy-Metal Removal—Experimental and by Thermodynamic Calculations

Energies, 2021
Sewage sludge is regarded as a potential source for soil fertilizer However, the direct utilization of sewage sludge in agricultural land is restricted since it also contains heavy metals, pathogens, and toxic compounds.

Nitrogen Fractionation in External Galaxies [PDF]

, 2019
In star forming regions in our own Galaxy, the 14N/15N ratio is found to vary from $\sim$ 100 in meteorites, comets and protoplanetary disks up to $\sim$ 1000 in pre-stellar and star forming cores, while in external galaxies the very few single-dish ...

Thermal-chemical Fractionation of Lignocellulosic Biomass

EUBCE 2019 Conference Proceedings, 2019
Biomass is a valuable, sustainable feedstock for the production of chemicals and materials, and will play an important role in the transition towards a Sustainable Process Industry. Bio-based products – products wholly or partly derived from materials of biological origin – can make the society more sustainable and lower its dependence on fossil fuels.

Observations of nitrogen isotope fractionation in deeply embedded protostars [PDF]

, 2014
(Abridged) The terrestrial planets, comets, and meteorites are significantly enriched in 15N compared to the Sun and Jupiter. While the solar and jovian nitrogen isotope ratio is believed to represent the composition of the protosolar nebula, a still ...

Assessment of landfill leachate biodegradability and treatability by means of allochthonous and autochthonous biomasses [PDF]

, 2020
The biodegradability and treatability of a young (3 years old) municipal landfill leachate was evaluated by means of chemical oxygen demand (COD) fractionation tests, based on respirometric techniques.

Oxidizable fractions of soil organic carbon in Caatinga forest submitted to different forest managements

Ciência Rural, 2018
: One of the main alternatives for the rational exploitation of the Caatinga biome’s natural resources is sustainable forest management. Soil organic carbon (SOC) and its fractions can be used to evaluate the conservation status of forest ecosystems ...
