eLM Zero
Your partner for carbon-neutral concrete
eLM Zero is an innovative, biochar-based solution designed to help you create sustainable concrete. Whether you're a precast manufacturer, a ready-mix producer, or a paver specialist, eLM Zero can reduce your concrete's CO2 footprint by up to 100% while retaining workability, strength, and durability within industry-standard ranges for conventional concrete.
Our partnership begins with a simple, collaborative process. We work with you to run tests and develop custom formulas, partially substituting traditional components like cement and aggregates.
The primary sustainability benefit of eLM Zero comes from the admix material itself. As a biochar-based product, it stores a significant amount of carbon. When used in your concrete, this stored carbon can compensate the embodied emissions from cement and other raw materials, making a carbon-neutral product a reality. This carbon remains permanently locked within the cement matrix for millennia, even after the concrete is recycled.
Our material is available in powder, granulate, and slurry formats, designed for seamless integration into your existing processes via manual or silo dosing, , just like other additives or fillers. These formats are offered in sacks, bigbags, IBC units, and via silo trucks for maximum flexibility.

Key benefits for concrete manufacturers
Carbon reduction
Reduce your concrete's CO2 by up to 100% or more. The biochar in eLM Zero stores carbon permanently and actively contributes to the environmental performance of your concrete.
Competitive advantage
Gain a competitive edge when bidding on construction projects with a sustainability focus by enabling a new use of biowaste to create circular building materials.
Seamless Integration
eLM Zero is delivered ready to use and is compatible with your existing production processes. In most cases, no additional investment in your facility is necessary.
Unchanged Quality
Your concrete products maintain optimal mechanical properties and workability, remaining just as robust and durable as conventional concrete.
Norm Conformity
eLM Zero is certified in accordance with EN 12878, which confirms its suitability for use in both reinforced and non-reinforced concrete applications.
Recyability
Concrete containing eLM Zero can be recycled just like conventional concrete according to EN 12620, making it suitable for further use without releasing carbon.
Areas of application:
eLM Zero is ideal for abating the CO2-footprint of various concrete products including ready-mix concrete, precast, pavers, slabs, street furniture, stairs, roof tiles, wall panels, façades, and decorative elements. It can be easily mixed into concrete at the plant or construction site.
