Abstract:
Global warming requires various emission reduction measures to capture carbon dioxide from the atmosphere or reduce its formation at emission sources. In addition to natural carbon sinks (such as oceans and trees), CO2 can also be captured in technical carbon sinks (such as geological carbon storage). Reducing the carbon footprint of concrete would require the partial replacement of CO2-intensive cement with alternative materials, such as biochar. The aim of this study is to develop new low-carbon industrial biochar concrete product concepts and alternatives through laboratory and pilot-scale experiments. The test concrete mixes include biochar produced from various industrial and agricultural side streams, such as Class A waste wood and hemp stalks. The goal is to demonstrate an innovative, climate- and energy-efficient, and scalable solution for constructing noise barriers. The barrier will be built using 3D-printed concrete containing biochar. Based on the demonstrated solution and the experiences gained from it, the commercial viability and market potential of the concept will be assessed. Preliminary results have been promising.
