Alternative Raw Materials

Rethinking our approach to raw materials

As we continue to look at ways to live more sustainably, we strive to identify further ways that we can reduce our reliance on virgin materials. Industrial waste and by-products can be the alternative raw materials of the future, contributing towards the circular economy.

In cement manufacturing, the largest source of CO2 emissions is from the calcination and clinker production process in the kiln. Clinker contains oxides of calcium (CaO), aluminium (Al2O3), silica (SiO2) and iron (Fe2O3) originating from clay, shale and limestone, which can be replaced with alternative raw materials.

Providing confidence that quality requirements will be fulfilled

At Totus, we understand the opportunities presented by alternative raw materials and the value that they can have when utilised in the correct environments. Our experienced team work closely with both waste producers and offtakers to put in place innovative solutions for mutual benefit.

Rigorous quality control protocols apply to both alternative fuels and raw materials. Our ongoing focus on quality and specification ensures that we can provide end users with sustainable alternative raw materials, a full audit trail and full supply chain visibility.

9.7x

The proportion of alternative fuels used in cement manufacture is now 9.7 times greater than in 1990

We collaborate with producers and offtakers, and have the knowledge and capability to supply custom blended alternative raw materials to meet ever changing requirements. Examples of industry waste and by-products we can help put to use as Alternative Raw Materials include:

  • Pulverised fly ash  
  • Blast furnace slag
  • Mill scale
  • Sewage and effluent sludge
  • Foundry sands
  • SPL refractory fraction
  • Alternative gypsum sources
19%

The cement industry has reduced its carbon emissions by 19% since 1990
