CO2-optimized lubricants
We pursue a range of developments and measures that avoid and reduce emissions. Our research and development department is continuously working on innovative solutions that reduce the burden on the environment and improve our customers' processes. A further step in this direction is the development ofCO2-optimized lubricants. ZG pursues three process technologies in the production ofCO2-optimized lubricants:
Gentle splitting - filtration of used oils
In the "gentle splitting" process, oil-water phases are separated and deposits are removed and cleaned by filtration. The result is a clean product that is suitable for direct reuse. The lubricants recovered through "soft splitting" save up to 90%CO2 compared to conventionally produced lubricants based on petroleum raffinate.
Refining - refining used oils into sustainable secondary raffinates
Our refinery creates a base oil for the future - exceptional, sustainable and virtually waste-free. Our refinery products are sustainably produced, resource-saving and high-quality lubricants. The lubricants produced by "refining" save up to 75%CO2 compared to conventionally produced lubricants based on petroleum raffinate.
Biogenic - Lubricants from biogenic base oils
The production of lubricants with biogenic raw materials represents an additional option for the production of CO2-optimized lubricants. Biogenic raw materials offer potential for environmentally friendly development, especially when recycling is not feasible. Examples of this are consumable lubricants such as punching oils and corrosion inhibitors.
By developing lubricants from biogenic raw materials, we save up to 40%CO2 compared to mineral oils from fossil raw materials.
E-mobility
Electromobility is the key to more sustainable andCO2-free mobility worldwide:
The electrification of the drivetrain results in completely new requirements, which in turn have an impact on the properties and composition of our lubricants. For us, electromobility is the central element of a more sustainable and climate-friendly transportation system. For this reason, we are already developing new lubricant solutions and coolants for these areas.
- Battery
- Fuel cell
- E-motor
- Power electronics
Lubricants for environmentally sensitive areas
They combine the idea of ecology and economy, are easily biodegradable (according to OECD degradability test) and technically mature.
- Saw chain oils + equipment cleaner
- Hydraulic oils
- Fat
- Concrete release agent
Energy-efficient cleaners for surface treatment
Low temperature cleaners that reduce energy consumption and heat input in paint shops.
- Process optimization
- Saving energy and increasing efficiency while maintaining or improving quality
- Reduction of the cleaning and process temperature
Sustainable printing ink developments
As a specialist in radiation-curing printing inks, we develop modern sustainable printing ink systems for packaging, label and commercial applications.
Our printing inks are faithful companions in your everyday life - from the supermarket to the dining table at home. Our printing inks are highly reactive systems that, thanks to their formulation, do not contain any kind of volatile raw materials.
This makes our printing inks solvent- and emission-free, thus offering an economic and ecological advantage.
- Mineral oil and solvent-free printing ink systems
- Low-migration printing inks for food packaging
- Energy-efficient LED ink systems
- Deinkable and recyclable ink systems
- Compostable printing inks for food packaging
Recycling + recovery
The concept of recycling is deeply rooted at Zeller+Gmelin. Our subsidiary Südöl recycles used machine and engine oils and processes them into new base oils and fuels. In this way, they are reintroduced into the production cycle instead of being disposed of at great expense.
Solvent distillation
Our Process Chemicals for Coatings (PCH) division offers, among other things, solutions for recycling process media containing light solvents (e.g. from paint shops).
On the one hand, the liquids containing light solvents from paint shops can be used as a secondary carbon source in alternative treatment plants. Instead of thermal waste disposal, these process media are returned to a useful purpose.
Returning used raw materials and products to the economic cycle is an important building block for increasing resource efficiency, conserving natural resources and ultimately securing our future.
