Hydrothermal Carbonization Technology for Wastewater Treatment under the “Dual Carbon” Goals: Current Status, Trends, and Challenges

Water, Journal Year: 2024, Volume and Issue: 16(12), P. 1749 - 1749

Published: June 20, 2024

Hydrothermal carbonization (HTC) technology transforms organic biomass components, such as cellulose and lignin, into valuable carbon materials, gases inorganic salts through hydrolysis, degradation polymerization, with significant advantages over traditional methods by reducing energy consumption, lowering pollutant emissions enhancing efficiency. In the context of global climate change, HTC plays a critical role in water environment management addressing industrial, agricultural, domestic wastewater challenges. The application extends to treatment, where hydrochar effectively adsorbs heavy metals, compounds, anions, thereby improving quality. However, challenges remain, optimizing process for diverse raw managing economic costs, environmental social impacts. Future research policy support are essential advancing technology. By reaction mechanisms, developing catalysts, promoting international cooperation, can significantly contribute towards achieving neutrality goals fostering sustainable development.

A novel green approach for Cr(VI) removal: application of tomato stem-based hydrochar assisted Fenton-like process

Chemistry and Ecology, Journal Year: 2024, Volume and Issue: 40(3), P. 305 - 321

Published: Jan. 22, 2024

Environmentally friendly catalysts have come to the forefront due cost of chemically produced and formation by-products harmful environment. Millions tons plant waste are every year, some which is disposed directly. In this study, tomato stem hydrochar (TSCH) was from stems by hydrothermal carbonisation (HTC) method, its use as a catalyst investigated. The optimisation Cr(VI) removal water carried out using Fenton-like process with TSCH resulted in 100% efficiency at 10 mg/L concentration, pH 2.00, 0.2 g/L catalyst, µL/L H2O2 60 minutes reaction time. thermodynamic kinetic data were analyzed, results found comply second-order removal. reusability investigated it emphasized that reusable for more than 5 uses. conclusion, TSCH, an environmentally friendly, inexpensive effective treatment process, can be used alternative wastewater terms both management economic friendly.

Opportunities and Constraints of the Adsorption of Rare Earth Elements onto Pyrolytic Carbon-Based Materials: A Mini-Review

Processes, Journal Year: 2024, Volume and Issue: 12(10), P. 2257 - 2257

Published: Oct. 16, 2024

Rare earth elements (REEs), comprising seventeen metallic elements, including lanthanides, scandium, and yttrium, are indispensable for modern technological industries due to their unique properties. However, supply is critically risky the European Union, with 95% of global production concentrated in China, Brazil, Vietnam, Russia, India, Australia. This mini-review examines adsorption REEs onto pyrolytic carbon-based materials as a sustainable recovery method from secondary raw materials. The review covers different types adsorbents used several research works, such activated carbon, chars, biochar, discusses mechanisms influencing factors.
