Our research is organized along clearly defined thematic areas that together cover the entire life cycle of polymeric materials.

### Research Area A: Sources and Emission Pathways of Microplastics

#### Research question

Where do microplastics originate—and how do they enter the environment and humans?

#### Content

This research area investigates primary and secondary sources of microplastics along the lines of use, abrasion, and aging. These include packaging, textiles, tire abrasion, agricultural applications, and industrial processes. The aim is to identify and quantitatively record emission hotspots.

#### Methods

- Realistic abrasion and aging tests
- Emissions measurements in technical and natural systems
- Modeling of transport and entry pathways

#### Relevance

The results form the basis for targeted prevention strategies and regulatory measures.

### Research Area B: Biodegradable and Bio-Based Polymers

#### Research question

How can polymers made from renewable raw materials be designed in such a way that they are functional *and* ecologically responsible?

#### Content

The focus is on new classes of polymers made from biogenic raw materials and the targeted control of their degradation behavior. The focus is not only on "degradability," but also on **predictable, measurable**, **and context-dependent degradation processes** that prevent the formation of microplastics.

#### Methods

- Synthesis of bio-based monomers and polymers
- Material design and structure-property analyses
- Quantitative biodegradation and mineralization tests

#### Relevance

This area combines material innovation with environmental compatibility and addresses one of the key weaknesses of today's bioplastics.

### Research Area C: Analytics, Standards, and Evaluation

#### Research question

How can microplastics be reliably identified, quantified, and evaluated?

#### Content

The development and harmonization of analytical methods is crucial for comparability and regulation. This area is working on robust measurement methods for microplastics and nanoplastics, as well as reference materials and standards.

#### Methods

- Spectroscopic and thermal analysis
- Particle and size distribution analyses
- Life cycle and impact assessments

#### Relevance

Only reliable data enables evidence-based decisions in politics, industry, and society.
