Who we are

HEION GmbH is headquartered in Holstein Switzerland, is working on the environmentally friendly conversion of industrial waste products, e.g. contaminated water, contaminated oils, heavy oils, carbon monoxide, nitric oxides, etc., into recyclable products. We do our part in protecting the environment and use our innovative new processes to produce controlled organic and inorganic substances which can convert greenhouse gases such as CO2 into valuable substances.

Ask the founders

How does Green Synthesis work without pressure and water supply?

We work without the local effects of pressure and temperature, as with conventional processes. The process is a precisely controlled energy conversion process where the energy is used to purposefully produce a synthesis or modulation.

To simplify the process, it can be compared with a light bulb and an LED. Both are used to produce light. A light bulb uses 5-6 times more electricity to produce the same brightness as an LED, as a lot of energy is converted into e.g. heat. An LED only uses the energy supplied to produce light.

Aren’t diesel/water mixtures an old hat?

HEION CLEAN DIESEL isn’t a diesel/water mixture, so not an emulsion.

Diesel belongs to the group of aliphatics.

Aliphatic hydrocarbons are non-aromatic organic, chemical compounds consisting of carbon and hydrogen. This makes them a subgroup of hydrocarbons.

Like all pure hydrocarbons, Aliphatic hydrocarbons are non-polar, lipophilic compounds. These compounds are not water-soluble. Surfactants must be added to make a diesel and water emulsion.

HEION CLEAN DIESEL does not use surfactants but instead a synthesis with a controlled energy conversion process. In the process molecular structures are formed, similar to esterification.

What happens to the water after the synthesis?

The excess water which is not used in the synthesis serves as a donor material for forming hydroxide ions in the permanent loop and completely consumed.

Can the water used be purified?

The contaminated water is purified in our systems and can be used for the synthesis.
