Maleki GmbH ’ s vision is deeply rooted in utilising green and sustainable materials . Business Development ( International ) Director of Maleki GmbH Rowan Soh explained : “ The vision and mission of the company revolves around the concept of making use of readily available green materials .”

At the heart of this vision is the commitment to replace conventional Ordinary Portland Cement ( OPC ) and Epoxy resin , a significant contributor to carbon emissions and pollution . OPC , a widely used construction material , has a considerable carbon footprint .

“ About one tonne of cement equals one tonne of CO2 being released .”

This alarming environmental impact prompted Maleki GmbH to seek an alternative approach .

Maleki GmbH ’ s eco-binder technology represents a groundbreaking solution to the carbon-intensive nature of conventional cement . Soh elaborated on the two critical aspects of this technology :

Chemical Reactivity : The eco-binder technology involves taking materials with a chemical composition similar to OPC , known as Pozzolanic materials , and reactivating them .

Soh emphasised : “ Pozzolanic materials usually have very low to no reactivity . When mixed with water , we create the reactivity so that it will be the underlying binder base .”

This innovative approach ensures that the binder material can form the necessary Bonds ( Calcium Silicate Hydrate – CSH ) without relying on OPC .

Chemical Composition Optimisation : Beyond reactivity , Maleki GmbH ’ s technology optimises the chemical composition of the entire formulation for a product .

Soh explained : “ The secondary part is that cement , in itself , OPC is not chemically optimised . For example , it usually has excess calcium , which creates calcium hydroxide ( CaOH or lime ), a weak-bond chemical . This creates the chemical weakness or efflorescence in traditional OPC-made materials .”

By fine-tuning the chemical composition , Maleki GmbH achieves superior quality and performance while maintaining cost-effectiveness .

CARBON REDUCTION AND SUSTAINABILITY

The revolutionary aspect of Maleki GmbH ’ s eco binder lies in its ability to reduce carbon emissions significantly .

“ Most building materials have a binder percentage of 20-30 per cent . By substituting OPC with a low carbon impact material , you will drastically reduce the overall emission of the underlying material .”

This translates to a remarkable carbon reduction of 70-95 per cent , depending on the specific product application .

“ The drastic reduction in carbon does not come with a reduction in quality but has unique and , in many aspects , superior quality compared to conventional technology ,” says Soh .

“ An example of this is in Maleki ’ s flooring , which has unique technical performance such as extremely high compressive strength of 50 newtons per square millimetre , excellent surface binding of four newtons per square millimetre , 1.5 bar pressure waterproofing , 500 Celsius plus Temperature resistance , abrasion resistance of A6-A9 on the Bohme scale and many more .”

Maleki GmbH adopts a collaborative approach to sustainability .

Soh said : “ Instead of antagonising the current industry , we work in harmony with our clients , mainly dry mortar companies , by offering our technology to reduce their carbon emissions while producing a superior product .”
