Autor: Lei Wang, Venkatesh Naidu Nerella, Dianmo Li, Yuying Zhang, Bin Ma, Egor Ivaniuk, Junyi Zhang, Xiaohong Zhu, Jianhua Yan, Viktor Mechtcherine, Daniel C. W. Tsang

Publikováno v: Communications Materials, Vol 5, Iss 1, Pp 1-10 (2024)

Abstract Three-dimensional (3D) concrete printing is a revolutionary technology in the construction industry. Here we show that climate-positive biochar is a carbon-negative additive for decreasing the carbon footprint of 3D printable concrete, while

Autor: Y. Wang, Y.-F. Ma, D. Muñoz-Esparza, J. Dai, C. W. Y. Li, P. Lichtig, R. C.-W. Tsang, C.-H. Liu, T. Wang, G. P. Brasseur

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 5905-5927 (2023)

To perform realistic high-resolution air quality modeling in a polluted urban area, the Weather Research and Forecasting (WRF) model is used with an embedded large-eddy simulation (LES) module and online chemistry. As an illustration, a numerical exp

Wood waste biochar promoted anaerobic digestion of food waste: focusing on the characteristics of biochar and microbial community analysis

Autor: Chao Zhang, Rui Yang, Meichen Sun, Shicheng Zhang, Mingjing He, Daniel C. W. Tsang, Gang Luo

Publikováno v: Biochar, Vol 4, Iss 1, Pp 1-12 (2022)

Highlights Biochar produced at 750 °C-60 min had the highest capacity to enhance AD of FW. Surface oxygen-containing functional groups and graphitization degree affected the capacity of biochar to promote AD. Biochar resulted in different microbial

Carbon-negative cement-bonded biochar particleboards

Autor: Liang Chen, Yuying Zhang, Claudia Labianca, Lei Wang, Shaoqin Ruan, Chi Sun Poon, Yong Sik Ok, Daniel C. W. Tsang‬

Publikováno v: Biochar, Vol 4, Iss 1, Pp 1-9 (2022)

Highlights Carbon-negative particleboard is for the first time pioneered by incorporating 70 wt.% biochar. Biochar addition in MOSC systems reduced the thermal conductivity. Further incorporation of SCMs improves the mechanical properties and CO2 seq

Biochar as construction materials for achieving carbon neutrality

Autor: Yuying Zhang, Mingjing He, Lei Wang, Jianhua Yan, Bin Ma, Xiaohong Zhu, Yong Sik Ok, Viktor Mechtcherine, Daniel C. W. Tsang

Publikováno v: Biochar, Vol 4, Iss 1, Pp 1-25 (2022)

Highlights Carbon-negative construction materials can be realised by emerging biochar applications. Incorporation of biochar can mitigate CO2 emissions and natural resource depletion. Biochar as construction materials foster the attainment of Sustain
