Kenya: Ndovu Cement, owned by Karsan Ramji & Sons, will build a 600t/day greenfield clinker plant and a limestone quarry in Mukawa, Kajiado County, according to regulatory filings. The project has already secured approval from the National Environment Management Authority. The company said the limestone quarry will ensure a reliable supply of 900t/day of limestone.
The facility is expected to reduce reliance on imports following a 17.5% levy on clinker imports introduced in July 2023, according to the Business Daily Africa newspaper. The measure was aimed at boosting local production and creating jobs, but has since led to a drop in cement consumption due to price increases and a fall in imports. Kenya-based cement producers had reportedly opposed an attempt to increase import duty on clinker, instead requesting a grace period of four years, until 2026, to allow them to build their own clinker production facilities.
Karsan began as a quarry operator in Kitengela, Kilifi and Nakuru, before beginning cement production in 2015 and launching Ndovu Cement in June 2015.
Germany: Holcim, E.ON Energy Infrastructure Solutions and Orcan Energy have launched a large-scale waste heat recovery project at Holcim’s Dotternhausen cement plant to capture 10MW of unused heat from kiln exhaust gases. The recovered heat will supply internal processes, potential district heating networks and power generation via Orcan Energy’s eP1000 Organic Rankine Cycle (ORC) system. E.ON is responsible for the planning, construction, financing operation and maintenance of the plant as part of an Energy-as-a-Service model. This is intended to present no initial investment costs for Holcim.
Holcim South Germany plant manager Dieter Schillo said “This project marks an important milestone on our path to decarbonising cement production. The smart use of industrial waste heat not only reduces our Scope 2 emissions, but also strengthens our role as a pioneer in sustainable building materials.”
