How Does Gnanli Landrou Transform Mud into Eco-friendly Concrete?

|
Ask a Question

Synopsis
  • This video and article introduce the invention of a cleaner, more eco-friendly concrete substitute inspired by the earthen houses of the inventor's home country of Togo.
  •  Students learn about the impact of concrete and cement on the climate and an alternative that could help reduce CO2 emissions.
Teaching Tips

Positives

  • This resource helps expand students' view of climate solutions beyond those of renewable energy, tree planting, and other commonly known solutions.
  • The solution presented uses technology and materials already in use rather than relying on technological innovation to become impactful.

Additional Prerequisites

  • The video ends at 3:33.
  • Students should be familiar with the greenhouse effect and how greenhouse gases and fossil fuels contribute to climate change.

Differentiation

  • Since the article and video present the same information, students can choose which to engage with based on preference or the availability of an Internet connection in class.
  • As an extension, have students research other innovative climate solutions from the links in the article or by looking through the table of solutions presented here.
  • To learn more about climate solutions and the industrial sector, have students take this course on industrial innovation.
  • When discussing social justice issues and global sustainability in social studies classes, consider how this solution could help with both.
Scientist Notes
This video resource presents the work of material scientist Gnanli Landrou, who has invented a cement-free building material called Cleancrete. The video provides a good explanation of how Portland cement is produced, the resulting carbon emissions, and why a cleaner building material is needed. The structural limitations of Cleancrete are acknowledged, which may provide a good discussion topic for students. This resource is well sourced, visually attractive, and is recommended for teaching.
