Pioneers of the circular economy
Sustainable use of resources through innovative waste recycling
FRENVI’s research and development work focuses on the sustainable recycling of waste materials. The aim is to use bio-based approaches to keep materials in the economic and nutrient cycle and to develop innovative concepts for the use of high-moisture organic by-products.
Our approach: Closing biological cycles
- Specialization in high-moisture waste materials
- Development of innovative recycling concepts
- Closed nutrient cycles
At the end of the possible product life cycles, our concepts primarily rely on natural processes such as composting or fermentation. In this way, we return valuable nutrients to the natural cycle and close the biological cycle.





Do you have by-products and residual streams that you would like to utilize in a more sustainable and valuable way?
Sustainable innovation for a circular future
Conserving natural resources and reducing waste are key challenges of our time. Our team at FRENVI has set itself the task of advancing the circular economy through innovative technologies and sustainable approaches. With a clear focus on the utilization of high-moisture organic by-products, we develop solutions that are not only ecologically sound but also economically viable.
Our vision: A closed loop for a sustainable world
We believe that residual materials are valuable resources when used correctly. Our goal is to keep materials in the economic cycle for as long as possible and ensure their return to the natural cycle. With bio-based solutions and innovative recycling concepts, we create added value for the environment and society.
Our core competencies:
- Specialization in high-moisture residual materials: We are dedicated to the challenge of converting organic by-products such as tea waste, paper waste, and brewery waste into valuable resources.
- Development of innovative recycling concepts: Using state-of-the-art technologies and research, we develop tailor-made solutions for various industries.
- Closed nutrient cycles: Our concepts aim to efficiently recycle nutrients and close the biological cycle.
Natural processes as the key to sustainability
At the end of a product’s life cycle, we rely on proven natural processes such as composting and fermentation to return nutrients to the soil. These processes enable us to reintegrate valuable raw materials into the natural cycle, thereby minimizing environmental impact.
