In yet another attempt by the European Union to lower CO2 emissions (see previous post), LEEMA (Low Embodied Energy Advanced) Novel Insulation Materials and Insulating Masonry Components for Energy Efficient Buildings) is a project geared towards finding an alternative to typical insulation materials. The alternative material that shows the most promise is a collection of inorganic polymers since they have so many uses and abilities. For example, they are incombustible, can be made from recycled materials, can be cured at low temperatures, and much more. There are also attempts in turning secondary materials, such as plastic waste, into a usable aggregate or binder for concrete. This would help make concrete lighter, more cost-efficient, and much more eco-friendly.
