US: The Portland Cement Association (PCA) has asked the US Department of Energy to add alternative fuels to its Material Circularity Framework. It said that alternative fuels in the cement manufacturing process are better for the environment than the use of traditional fuels and that it diverted a significant amount of materials from landfill. The PCA said that the DOE’s Framework “…should address how to promote circularity through alternative fuels and replacement of raw materials to promote reducing greenhouse gases emissions.”
The DOE released its draft strategic framework ‘Circularity for Secure and Sustainable Products and Materials’ in October 2024. It asked for feedback from stakeholders by mid-December 2024. The framework is intended to identify opportunities and challenges to use circularity to decarbonise industry, secure supply chains, benefit communities and create jobs. The draft mentions recycling concrete and generating secondary cementitious materials from recovered material streams.
