The project consortium aims to develop solutions to the current problems of rising raw material prices and uncertain raw material availability as well as rising energy and process costs through ''bio-lubrication''. Our solution approach addresses the increase of raw material resilience through a previously unused biogenic source - insect fats - as well as the improvement of process and energy efficiency using the example of metal forming. Our platform technology is designed in such a way that it can also be transferred to other raw materials and processes

For some time now, the chemical industry has been confronted with increasing limitations in the area of biogenic fats and oils. This has been further exacerbated by the current crisis in the supply of raw materials. Waste fats and animal fats are no longer available, as they are almost completely used for the production of hydrogenated oils. Many years of research efforts in the field of algae oil for the chemical industry have not yet been successful. Algae oil only plays a role in the food sector or in biogas production. Although large quantities of vegetable oils are available on the world market, they are used almost exclusively in food production or in the fuel sector due to legal requirements. However, the current and continuing supply crisis for fossil raw materials makes the development of competitive, bio-based product alternatives in the chemical industry essential. Ideally, alternative raw materials should be found that can be produced in Europe independently of the fluctuations and risks of the global market. Insect fats could become a suitable alternative in the future. A promising chemical profile speaks in favour of this, which is disadvantageous for food production but very promising for the chemical industry. In lubricant applications, there is the problem of insufficient interaction between lubricants and material surfaces. This mainly results from a lack of coordination between the two systems and leads to unnecessarily high wear, faster tool wear, faster lubricant ageing, higher friction losses and process temperatures. ''Bio-Schmier'' also aims to make a significant contribution to material efficiency and to extending the operating times of media and processes in order to reduce production and energy costs. Insect production can be carried out using domestic residues as a feed substrate, providing a sustainable source of raw materials for oleochemistry.

Our solutions are designed to help counteract the current problems of rising raw material prices and uncertain raw material availability as well as rising energy and process costs.

Our solution approach addresses the increase of raw material resilience through a previously unused biogenic source as well as the improvement of process and energy efficiency using the example of metal forming. We want to develop a new generation of bio-based lubricant systems based on insect fats that can interact with customised tool coatings. The platform technology developed should also enable high-performance applications with completely bio-based media while maintaining the process technology standard.

 

Our project goals are:

  • Development of an innovative process for insect breeding that enables the provision of both protein and fat using feed substrates that are as indigenous as possible and based on non-/low-value organic side streams.
    • Provision of a customised fatty acid profile through adapted larval nutrition with suitable side streams
  • Development of a lubricant system using esterified and transesterified insect fats with a specific fatty acid distribution and an additive system based on vegetable side streams from the agricultural and food industry.
    • Ensuring high tribological functionality and high solubility of additives in the base fluid
  • Development of customised tool surfaces. The polar and disperse portion of the surface energy is to be adapted by modifying the tool coatings with specific alloying elements. Furthermore, additive-specific docking elements are to be incorporated.
    • Possibility of improved lubricant wetting and integration of performance additives to improve the tribological additive effect
  • Demonstration and proof of function of the technology using metal forming as an example, including the effects on subsequent processes and recyclability.
    • Acquisition of industrial projects and licensing as well as transfer to other fields of technology

Strategic classification

In the FhG lead project ''Future Proteins'', the BMBF lead programme Bioeconomy in Metropolitan Areas (projects: InFeed and InA) and the BMBF junior research group ''SymBioÖkonomie'' (insects and their symbiotic microbes for the circular bioeconomy), concepts for the sustainable provision of protein-based food and feed are being developed in the Bioresources section of the IME. Utilisation of the insect fat produced has not yet been addressed. This ''cycle gap'' is to be closed by ''Bio-Schmier'' and at the same time a bridge is to be built from food production to the chemical industry. The co-operation between the participating research institutes means that the entire lubricant development process chain is being mapped for the first time using a sustainable development approach.
