Description
The First Commercial Electrochemical Cement Manufacturing Project, Led by Sublime Systems, Plans to Build a New, Ultra-Low Carbon Cement Manufacturing Facility in Holyoke, Massachusetts. Sublime Systems’ New Method to Make Cement Replaces Carbon-Intensive Limestone with Abundant Calcium Silicate-Based Feedstocks, Resulting in Industry-Standard Cement That Is Produced Electrochemically Instead of Using High Heat. By Demonstrating This Transformational Process That Was Previously Supported by ARPA-E, Sublime Systems Would Strengthen American Supply Chains for Low-Carbon Products, Increase Transparency for Product Environmental Impact and Performance, and Catalyze Industry-Wide Change. The Project Expects to Create 70-90 Permanent Manufacturing Jobs in a Community That Once Produced Nearly All of the United States’ Writing Paper But Has Seen a Decline in Industry Over the 20TH Century. Sublime Systems and the United Steelworkers Have Signed a Strategic Partnership Agreement Supporting Sublime Systems’ Employees’ Right to Organize at the Holyoke Factory. The Company Has Also Signed Memoranda of Understanding to Negotiate Project Labor Agreements with the Region’s Building Trade Unions. Based on Robust Engagement and Discussion with the Holyoke Community, Sublime Systems Additionally Plans to Support the Holyoke K-12 Education System Through Curriculum Enhancement and Teacher Support in Partnership with the Smithsonian Science Education Center and Facilitate a Long-Term Training Pipeline for Holyoke and the Broader Pioneer Valley.
