Hazemag On Target

In January 2022, Hazemag received an order to supply an Apron Feeder HAF 25142 and a primary Center Sizer HCS 1025 from one of the leading cement and aggregate producers around the world to ensure the continuous production of its facility in Florida.

This modular plant will process 2,000t/h coral limestone with flint and clay inclusions in the future. The feed size is up to 122cm and is crushed to 25cm.

A great deal of attention was paid not only to proven and reliable machine technology, but also to professional support in plant design.

Despite the difficult circumstances, the covid-19 pandemic and the war in Ukraine, production has been within the agreed timeframe and the equipment is now ready for delivery.

The new plant will go into operation before the end of this year.

dust-free solution

Bruks Siwertell has delivered a new Siwertell road-mobile ship unloader for dust-free cement handling operations in Belle Chasse, Louisiana, US for returning customer, Cemex. The 10 000 S nextgeneration unit adds to a portfolio of Siwertell technology used by the Mexico-based multinational building materials company.

“We are the only company able to offer a mobile ship unloader around this size,” explains Pedro Alfaro, Project Development Engineer, Bruks Siwertell. “This was a significant driver for the contract, along with our ability to deliver the unit within a short timeframe.

“The road-mobile system also offers a great deal of flexibility, enabling the operator to easily transport ship unloading capabilities between sites,” Alfaro continues. “It is now working hard, and keeping up with significant rises in cement demands.”

Siwertell screw-type technology has totally enclosed conveying lines, which ensure no spillage and keeps fugitive dust to an absolute minimum. “Environmental protection was another key element behind Siwertell technology being selected,” he adds.

The ship unloader was delivered towards the end of 2022 and offers a continuous rated cement handling capacity of 300t/h and can discharge vessels up to 10,000 dwt.

Circular Systems

Cemex has announced the launch of Regenera, a business that provides circularity solutions across Europe, the Middle East and Africa (EMEA), including recovery, management, recycling, and co-processing of waste.

Regenera leverages Cemex’s substantial international footprint and the ability of its production processes to use non-recyclable waste and industrial by-products as more sustainable substitutes for fossil fuels and natural raw materials. Regenera is actively working on several major projects across the EMEA region.

In France, Regenera operates a multiservice dock located in an industrial harbour in Paris offering a wide range of circular economy services to the construction industry. The company receives a variety of materials, including construction debris, excavated material and inert soil, which it sorts, processes, and transforms into recycled aggregates or inert material used to restore quarries.

In Egypt, Regenera has signed a three-year agreement with the NGO Very Nile to support waste removal efforts from the Nile River. The recovered nonrecyclable materials will be used to substitute fossil fuels at Cemex’s Assiut cement plant, with other materials being recycled or upcycled.

Additional projects are also underway in CEMEX’s wider global business.

In Mexico, Regenera is already processing almost two million tons of waste streams per year, and is now working with the government of Mexico City on its “Zero Waste Plan”. Meanwhile, in Colombia, Regenera has signed an agreement to work with Tetrapak, to receive and separate multilayer cartons at its facility and return those that can be reused or recycled.

Regenera aims to serve a diverse client base that includes industrial, manufacturing, construction and waste collection companies, NGOs, and governments. It provides sustainable solutions for three major waste streams: municipal and industrial, construction, demolition, and excavation (CDEW), and industrial byproducts.

Sergio Menendez, regional president for Cemex EMEA, comments: “Growing a circular economy is a key pillar of our dedicated climate action strategy, Future in Action, as it not only reduces waste being sent to landfill, but also helps to preserve natural resources and reduce emissions. The launch of Regenera is therefore the latest step in our efforts to be a net-zero CO2 company globally by 2050.

“We believe that Cemex and other companies in the building materials industry can be a major contributor to a more circular society, and our role in utilising waste and by products is key to a greener economy.”

Cemex’s Future in Action programme is pioneering ways to increase the use of waste and residues as alternative raw materials and fuels. At the forefront of the circular economy in the construction value chain, Cemex is committed to achieving true carbon neutrality.
