Green cement in the US is becoming big business28 March 2024, Published under Cement NewsThe US cement market has been playing catch-up with markets such as Asia where the share of the market held by supplementary cementitious materials (SCM) has grown substantially over the last decade. While factory-produced Portland limestone (Type IL) cement is now rapidly expanding its market share in the US, future innovation is seeking to increase clinker replacement by SCMs even further with the production of a new generation of green cements. SCMs such as fly ash and slag cement cur... |
Sublime Systems to build first commercial plant27 March 2024, Published under Cement NewsUS-based Sublime Systems has been awarded up to US$87m in funding by the US Department of Energy (DOE). The funding will be used to accelerate construction of Sublime’s first commercial manufacturing plant in Holyoke, Massachusetts. Sublime, which first launched in 2020, has scaled up its electrochemical cement manufacturing process to a pilot capacity of 250tpa at its plant in Somerville.

Sublime Systems secures funding for low-carbon cement18 January 2023, Published under Cement NewsUS-based Sublime Systems has raised US$40m to develop new technology to produce low-carbon cement. According to Bloomberg, Sublime has come up with a process that reduces energy use and carbon emission by splitting the cement-making process into two parts. The first step is the production of calcium in a form that will chemically react with silicon, the key element in sand. Sublime reduces energy use and carbon emissions in this step by avoiding limestone and using electricity rather tha... |
