Development of an evaluation platform for growth factors for the production of cultivated meat
The traditional production of meat from livestock farming and fishing results in notable environmental repercussions, including but not limited to biodiversity depletion, water pollution, and the emission of greenhouse gases. One approach to addressing this issue is cultivated meat, produced through cell culture techniques. Various companies have already presented products produced in the laboratory and at pilot scale in recent years, but mass-market implementation has not yet been achieved. There are also technological challenges to overcome to enable large-scale production of cultivated meat, in addition to supply chain, legal, and various socio-economic requirements.
One central challenge is ensuring the availability of economically feasible and bioactive growth factors for large scale production. This media component is required for cell proliferation and differentiation. To ensure the bioactivity of native and tagged growth factors, as well as partially synthetic or modified sequence variants, suitable testing systems are necessary. To enable a reliable assessment of future performance, testing systems are needed to simulate cell growth in bioscaffolds with varying characteristics such as porosity, polymerization degree, and diffusion properties under real-world conditions.
Perfusion bioreactor modules are being developed using 3D printing techniques to accomplish the addressed challenges. These modules are designed to provide a controlled environment for growing tissue and to observe various scenarios of growth factor utilization in different bioscaffold configurations. In our scale-down approach investigation of small quantities of alternative growth factors under real-world conditions is facilitated and supports the development of a future industry dedicated to cultivated meat production.

Advanced LCA and TEA Methodologies for Technical Evaluation of Cultivated Meat
The research project integrates a comparative Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA) of cultivated meat. The objective is to compare the environmental and economic impacts of various protein sources, including cultivated meat, precision fermentation, and traditional farming. Key elements of the project include:
- Utilizing real-life data to assess the environmental impact and energy requirements of each protein source.
- Critically analyzing existing LCA assumptions about cultured meat and updating them with current, realistic data.
- Conducting scenario analyses to explore how different assumptions affect LCAs and using Monte Carlo simulations for predicting future CM emissions.
- Adhering to ISO14044 standards, focusing on assessing energy use, greenhouse gas emissions, and land use in CM production.
The outcome aims to provide a comprehensive understanding of the environmental and economic implications of various protein sources, contributing to informed decision-making in sustainable food production.
