Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Torrefaction of Sewage Sludge: Kinetics and Fuel Properties of Biochars

Energies, 2019
We propose a ‘Waste to Carbon’ thermal transformation of sewage sludge (SS) via torrefaction to a valuable product (fuel) with a high content of carbon.

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

Land Degradation &Development, Volume 37, Issue 13, Page 8963-8985, 15 August 2026.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.

Torrefaction of residues and by-products from sunflower chain

Journal of Agricultural Engineering, 2013
The high heterogeneity of some residual biomasses makes rather difficult their energy use and standardisation is a key aspect for these fuel products. Torrefaction is an interesting process used to improve the quality of ligno-cellulosic biomasses and to

Applications of Textile Waste as Reinforcement in Fiber‐Reinforced Polymer Composites for Circularity—A Review

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
This review highlights the utilisation of textile waste in fibre‐reinforced polymer composites to reduce environmental impacts of pre‐ and post‐consumer textile waste. It critically examines waste composites’ manufacturing processes, their structural details, mechanical, thermal, physical properties, while discussing chemical treatments, hybridization ...

Torrefaction of Willow in Batch Reactor and Co-Firing of Torrefied Willow with Coal

Energies, 2023
The torrefaction process represents a thermal conversion technique conducted at relatively low temperatures ranging between 200 to 300 °C. Its objective is to produce fuel with a higher energy density by decomposing the reactive portion of hemicellulose.

Sustainable Flame Retardant System with Thermomechanically Modified Stinging Nettle Tailored for Polyamide 12

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
A sustainable flame retardant system for polyamide 12 is developed by combining melamine polyphosphate with thermomechanically modified stinging nettle. The plant‐derived component alters degradation pathways, enhances char formation, and reduces heat release.

Upgraded Pellet Making by Torrefaction—Torrefaction of Japanese Wood Pellets

Journal of Sustainable Bioenergy Systems, 2015
Upgraded wood pellets were produced and evaluated by torrefaction of wood pellets. In this study, conventional wood pellets were initially prepared and subsequently torrefied on a laboratory and then larger scale. During the laboratory scale production, pellets from wooden parts of Japanese cedar (sugi, Cryptomeria japonica) and Japanese oak (konara ...

An Index for Quantifying the Degree of Torrefaction

BioResources, 2017
Torrefaction, a thermochemical pre-treatment process, is used to enhance the properties of biomass to make it more compatible with solid fossil fuels. A quantitative index (TI) is proposed here to define the degree or quality of torrefaction especially ...
