Release of nutrients and organic carbon in different soil types from hydrochar obtained using sugarcane bagasse and vinasse
(2019-01-15)
Hydrothermal carbonization of byproducts from the sugarcane industry generates a solid material (hydrochar) rich in carbon and nutrients with the potential to be used as a soil conditioner. In this context, the objective ...
Hydrochars produced with by-products from the sucroenergetic industry: a study of extractor solutions on nutrient and organic carbon release
(2019-03-01)
Hydrothermal carbonization transforms biomass into value-added material called hydrochar. The release of nutrients (P, N, Ca, Mg, and K) and organic carbon (TOC) from hydrochar in different extractive solutions was ...
Magnetic hydrochar nanocomposite obtained from sunflower husk: A potential material for environmental remediation
(Elsevier Science, 2021-09-05)
A novel magnetic hydrochar composed of nanosized magnetite (Fe3O4) particles supported on a hydrochar matrix was synthesized via hydrothermal carbonization of sunflower husk, employing phosphoric acid as the activating ...
Development and characterization of activated hydrochars from orange peels as potential adsorbents for emerging organic contaminants
(Elsevier, 2015-05)
Activated hydrochars obtained from the hydrothermal carbonization of orange peels (Citrus sinensis) followed by various thermochemical processing were assessed as adsorbents for emerging contaminants in water. Thermal ...
NUTRIENT AND ORGANIC CARBON RELEASE IN SOILS CONTAINING WASHED AND NOT WASHED HYDROCHAR COMPARED TO ANTHROPOGENIC SOILS
(Soc Brasileira Quimica, 2019-03-01)
Hydrochar washed (1.0, 2.5, 5.0 and 10.0 %) and not washed (10.0%) produced by hydrothermal carbonization using vinasse and sugarcane bagasse was applied in sand, ultisol and oxisol columns, and the release of NO3-, ...
Insights on Molecular Characteristics of Hydrochars by 13C-NMR and Off-Line TMAH-GC/MS and Assessment of Their Potential Use as Plant Growth Promoters
(2021-02-15)
Hydrochar is a carbon-based material that can be used as soil amendment. Since the physical-chemical properties of hydrochar are mainly assigned to process parameters, we aimed at evaluating the organic fraction of different ...
Transforming Sugarcane Bagasse and Vinasse Wastes into Hydrochar in the Presence of Phosphoric Acid: An Evaluation of Nutrient Contents and Structural Properties
(2017-06-01)
Purpose: Sugarcane bagasse and vinasse are wastes generated at large scales by the Brazilian sugarcane industry. Therefore, new waste treatment and management practices are essential for a sustainable industrial growth and ...
Multianalytical characterization of biochar and hydrochar produced from waste biomasses for environmental and agricultural applications
(2019-10-01)
Biochar (BC) and hydrochar (HC) are solid by-products obtained from various types of biomasses through the processes of pyrolysis and hydrothermal carbonization, respectively. Both BC and HC represent a sustainable solution ...
Hydrochar from sugarcane industry by-products: assessment of its potential use as a soil conditioner by germination and growth of maize
(2021-12-01)
Background: Hydrothermal carbonization (HTC) is a thermochemical process to convert biomass in carbon-rich materials (hydrochar). The use of sugarcane industry by-products in HTC has been evaluated, generating a hydrochar ...
Hydrothermal carbonization of sugarcane industry by-products and process water reuse: structural, morphological, and fuel properties of hydrochars
(2021-01-01)
Hydrothermal carbonization (HTC) has emerged as a promising technology for sustainable use and waste valorization. One major challenge of HTC technology is the process water (PW) disposal or reuse, which is rich in dissolved ...
