Maleki GmbH is a company dedicated to using technology to
address global climate change by finding green solutions for
building materials. Located in Osnabrück, Germany’s Green
City of Peace, Maleki GmbH was established in 2007 by
Hossein Maleki and Matthias Gelber.

The Maleki Triple-Benefit
GREEN
At Maleki, we replace cement with safe industrial
byproducts and other alternative substances. This
keeps us from tapping into natural resources while
using materials which would have ended up in
landfills. The end result is a greatly reduced carbon
footprint of between 60 to 90% - even better than
other competing green products.

1. Eco Binder System
Cement is the binding component of concrete
and mortar products. It contains three key
ingredients:
CaO
Calcium Oxide
SiO2
Silicon Dioxide
• Obtained from limestone (CaCO3).
• Extremely polluting & energy-intensive
process involves extracting the
limestone, transporting it and heating it
to 1350oC.
• 60% of the limestone’s mass is released
into the atmosphere as CO2.
Al2O3
Aluminium Oxide
• Known as corrective
minerals, these ingredients
are mixed with Calcium Oxide
to create OPC.

Certain waste materials from other industrial processes also possess all three primary
components of cement. However, activating these materials from their inert (non
reactive) state and forcing them to react has always been a challenge.
Maleki’s Eco Binder System utilizes advanced green chemistry to activate
these by-products and turn them into cement.
• These by-products undergo a stringent analysis for heavy metals and
other toxic substances first.
• Eco Binder cement and dry mortars are inherently stronger, have
improved chemical resistance and better physical characteristics.
• There is no longer any need to quarry limestone for OPC production.
• Maleki Eco Binder cement and dry mortars are cost competitive, last
longer, and do have minimal CO2 emissions!

Outdoor Air Quality
• Regulations say how much pollution is
acceptable
Indoor Air Quality
• Not regulated
Indoor Air Quality
• Pollution inside the typical American home
is 2 to 5 times worse than air outdoors
• Indoor air pollution is one of the top 5
most-serious environmental risks to public
