Discover Value: LE Technology

Innovative technology to reduce environmental impact

Progressive industrialization has led to significant environmental pollution in many places. The public demands massive environmental precautions to counteract this promptly. With Ecosil® LE (Low Emission), Clariant provides the possibility to reduce the generation of harmful emissions in the foundry industry by up to 80%. This creates value for the environment and Clariant’s customers.

of harmful emissions

Clariant provides the option to reduce the possibility of harmful emissions in the foundry industry by up to 80%

What is bentonite?

Bentonite is a mix of various clay minerals and is characterized by an especially high ability to absorb water, a high swellability, and thus a good bonding capacity for heavy metals and toxic substances, for example.

Areas of application for bentonie-based additives: Civil engineering, drilling, metal casting, ceramics, detergents, papermaking, pharmaceuticals, cosmetics, feed, edible oil purification

Interview with Thomas Engelhardt

Thomas Engelhardt Lab Head Application Development EMEA and inventor of the LE Technology

»Our customers have monetary benefits.«

Mr. Engelhardt, how was the LE Technology developed?

Early on, we began by analyzing where the most harmful substances were created in the foundry process and how they could be avoided. What we discovered is that the green sand from which the molds are made for the foundry process can be manufactured in a much more environmentally compatible and efficient manner with special bentonite-based additives.

Which emissions does this include and how many of them can you actually avoid?

The foundry process is conducted at temperatures of up to 1 500°C and in doing so, produces a variety of BTEX1 emissions, which are all considered to be carcinogenic. These harmful emissions can be reduced by more than 80% when using bentonite-based LE additives.

Does LE Technology have other positive properties?

In addition to the environmental factor, our customers benefit from increased efficiency in the production process, improved product quality and less waste. Those are monetary benefits.

Innovation Highlight: HOSTAFRAC® SF


With HOSTAFRAC® SF 13213, Clariant has achieved a technological breakthrough to extract shale oil in an environmentally acceptable and highly efficient manner using hydraulic fracturing. Extensive testing in direct collaboration with the end-user customer showed that enhanced flow back of the hydraulic fracture fluid could be achieved when using HOSTAFRAC® SF 13213 when compared to other commonly used flow-back aids.

This is achieved by reducing the capillary forces between the grains of rock in the reservoir using the sugar-based surfactant, thereby enabling an increase in the flow rate and speed of well clean-up. The product meets the rigorous sustainability criteria for the Clariant EcoTain® label.

  • ARKOMON® XP 1014, Emulsifier for Explosive Emulsions

    Mining Services has developed an emulsifier technology allowing the use of low grade ammonium nitrates (AN) for explosive emulsion producers; providing a significant cost reduction and operational flexibility. This technology provides excellent stability of emulsions made with low grade ammonium nitrites with high crystal modifiers content. For producers not fully integrated in AN production this product provides superior performance and cost savings in the field. Additionally, this innovative product can be used with a wide range of AN grades, providing significantly improved operational flexibility.
