Philippines: Holcim Philippines has signed a deal to receive 6.5t/yr of shredded waste from Bunawan municipality’s Panacan barangay for co-processing as alternative fuel (AF) in its cement production. SeeNews has reported that Holcim’s waste management subsidiary GeoCycle will process the AF. The partners aim to increase the volume of deliveries in future.

Davao cement plant manager Sam Manlosa said, “We are proud to provide our host barangay Panacan a sustainable waste management solution and thankful for their trust. We hope this partnership will further expand to other communities and the entire city of Davao so we can be a stronger partner in its sustainable progress.”

Panacan is the 28th community throughout the Philippines to enter into a waste management partnership with Holcim Philippines, and its 18th new partner in 2022. In August 2022, the company secured deliveries of waste collected in Bulacan province’s Binangonan, Cainta and Taytay municipalities in Rizal province for co-processing at its Bulacan cement plant.

Canada: Lehigh Cement has initiated the administrative process to begin the use of alternative fuels (AF) in cement production at its Picton cement plant in Ontario. Under the company’s plans, the plant will substitute 200t/day of AF for coal and petcoke at the plant. Possible AF sources include excess seed from farm feed production in Ontario. The Picton cement plant previously reduced its CO₂ emissions per tonne of cement by 20% through assorted sustainability initiatives.

Picton plant manager Carsten Schraeder said that the move will support Canada’s 2030 emission reduction plan, and also take pressure off landfill sites.

South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.

This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.

The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NO_x emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.

Turkey: KÇS Kipaş Çimento has placed an order with KHD Humboldt Wedag for a Pyrorotor for its Kahramanmaraş cement plant. The supplier says that the equipment will enable the plant's calciner to achieve an alternative fuel (AF) substitution rate of 90%. It will additionally restrict NO_x emissions to 800mg/Nm³. After a short shutdown for assemblage of gas duct connections, KHD expects to commission the upgraded system in mid-to-late 2023.

The company says that the KÇS Kipaş Çimento contract represents its 11th Pyrorotor order globally and the first in Turkey.

Czech Republic: Lafarge Cement says that it has achieved an alternative fuel (AF) thermal substitution rate of 95% at its Čížkovice cement plant. The plant's fuel mix includes contaminant fractions from local plastic recycling. As a result of the move, the plant no longer uses any natural gas in its cement production.

In 2022 as a whole, the producer plans to increase its share of reduced-CO₂ cement sales, increase construction waste recycling in its products and reduce its cement's water consumption.
