Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Biochar and Hydrochar as Soil‐Based Carbon Sequestration Technologies: Implications for Greenhouse Gas Mitigation

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Biochar and hydrochar have emerged as promising carbon‐based amendments for enhancing soil carbon sequestration and mitigating greenhouse gas emissions. This review synthesizes and critically compares current knowledge on the production technologies, physicochemical properties, stabilization mechanisms, carbon persistence, and life‐cycle ...

Recent Progress on Emerging Applications of Hydrochar

Energies, 2022
Hydrothermal carbonization (HTC) is a prominent thermochemical technology that can convert high-moisture waste into a valuable product (called hydrochar) at a relatively mild treatment condition (180–260 °C and 2–10 MPa). With rapidly growing research on HTC and hydrochar in recent years, review articles addressing the current and future direction of ...

Hydrochar effects on the microstructure and hydromechanical behaviour of unsaturated compacted soils

Journal of Rock Mechanics and Geotechnical Engineering
The effectiveness of using vegetation to stabilise shallow soil slopes heavily depends on the survival of vegetation, yet the amplification of extreme events induced by climate change threatens the health of plants covering slopes.

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Activated Carbons from Hydrochars Prepared in Milk [PDF]

Scientific Reports, 2019
AbstractHydrothermal carbonization converts organics in aqueous suspension to a mixture of liquid components and carbon-rich solids (hydrochars), which in turn can be processed into activated carbons. We investigated whether milk could be used as a medium for hydrothermal carbonization, and found that hydrochars prepared from milk, with or without an ...

Removal of Escherichia coli by Intermittent Operation of Saturated Sand Columns Supplemented with Hydrochar Derived from Sewage Sludge

Applied Sciences, 2017
Hydrothermal carbonization (HTC) technology can convert various types of waste biomass into a carbon-rich product referred to as hydrochar. In order to verify the potential of hydrochar produced from stabilized sewage sludge to be an adsorbent for ...

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

Safety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...
