- Sustainability category: Energy, Water
The cement industry accounts for approximately 5-7% of global greenhouse gas emissions, and the traditional cement curing process is highly water intensive. As cement is the second most utilized product in the world (after water), improving its manufacturing processes can have a significant impact on global sustainability.

- Solidia technologies has developed a new way to produce concrete and cement that reduces the material’s carbon footprint by up to 70%, and water consumption by 60-80%.
- The technology uses a lower kiln temperature for manufacturing of cement, which reduces energy consumption, GHG emissions, and costs.
- The concrete is cured with cO2 rather than the traditional curing process using water, reducing the process’s water use.
- The resulting material is not only more durable and higher performing than traditional concrete, it is also less expensive to produce.
- Building and contracting companies
- Local Departments of Building
- Private developers and homeowners (building new buildings/homes)
- The first 3 steps in deploying technology:
- Insert Solidia cement into local building codes as a mandatory material (banning traditional cement).
- Seek investments to build additional factories and ramp up production capabilities.
- Create licensing deals and training programs with existing cement companies, allowing them to produce Solidia Cement.
- Comment on “The Compost Professor: A Smart Composting System” by JM4202
As someone who tried home composting for a while (on the roof of my building), I think this is a very good idea, but still has some issues, especially for composting in urban areas.
One of the biggest problems I faced was lack of dry material to add to the compost. In suburbs, homeowners usually have lots of dry leaves they can use from their yards, but that is usually not the case in cities. It seems that this technology is geared towards suburban dwellers, it would be interesting to find a technological solution for home composting in cities.
