Rezy-Spezi: Innovative solutions for recycled materials and sustainability in the circular economy

Welcome to "Rezy-Spezi" – a research project for advanced solutions in recycled material use. In light of the growing importance of sustainability and the circular economy, Rezy-Spezi is dedicated to exploring efficient applications of recycled materials across various industries. Our focus is on identifying potential uses for recycled materials through the systematic analysis of relevant standards and requirements. Together, we are shaping a sustainable future.

Rezyclate use

Project overview

Rezy-Spezi is a pioneering research project funded by the German Federal Environmental Foundation (DBU) and conducted by SKZ - The Plastics Centre in collaboration with plastship. The project analyses specific standards and requirements across various industrial sectors to identify potential applications for recyclates. Our focus is on the automotive, construction, and packaging industries, where we are closely examining the use of recyclates and developing solutions for the industry.

Main objectives of the project

Identification of recyclate usage potentials

Analysis of standards and manufacturer-specific requirements across industries
Analysis of standards and requirements

Examination of standards that promote or hinder the use of recyclates
Development of action recommendations

Specific recommendations for the industry to increase the use of recyclates
Enhancing societal acceptance

Exploration of customer perspectives on products containing recyclates

Project results

► A total of 33 recycling companies participated in the survey, providing both post-industrial and post-consumer qualities.
► The participating companies represent 10% of the European recyclate market based on their production capacities.

Standards analysis

Our analysis shows that general standards restrict the use of secondary plastics, particularly in drinking water and hygiene applications. However, we see significant potential in the automotive and construction industries.
Specific requirements

Many companies continue to use virgin materials because customer requirements often exclude recyclates. However, our research shows the possibility to adjust requirements to increase the use of recyclates without compromising quality.
Acceptance

The acceptance of recyclates heavily depends on the perception of quality attributes such as smell, texture, and appearance. However, our surveys show that many consumers are willing to pay higher prices for sustainable products.

Recyclate volumes by industry

As part of our project, we have obtained detailed and insightful results across various industries. These provide important insights into current developments, particularly regarding current recyclate volumes and the potential that arises from reduced requirements in the plastics recycling industry.

Packaging

► Current recyclate volumes: 150.000 t/y
► Potential recyclate volumes: 195.000 t/y (30% increase)
Automotive industry

► Current recyclate volumes: 80.000 t/y
► Potential recyclate volumes: 100.000 t/y (25% increase)
Construction industry

► Current recyclate volumes: 100.000 t/y
► Potential recyclate volumes: 135.000 t/y (35% increase)
Electronics industry

► Current recyclate volumes: 50.000 t/y
► Potential recyclate volumes: 60.000 t/y (20% increase)

Potential to increase volumes and required investments

Overall potential across all industries
With a cross-industry reduction in certain technical requirements, recyclate volumes could be increased by up to 28%.

Key levers
► Contamination tolerances: A slight increase in acceptable contamination levels could significantly boost recyclate volumes.
► Material diversity: Expanding the types of plastics used while simultaneously adapting processing technologies.

Required investments
► Machinery optimisation: 60% of surveyed companies see the need to invest in new separation and sorting technologies.
► Collaborations: 70% of companies highlight the importance of closer cooperation along the value chain to improve material quality.

Cross-industry recommendations

Based on the insights gained, we have developed the following cross-industry recommendations:

Expansion of recyclate markets

► Cross-industry collaboration:
There should be a stronger exchange between different industries to identify synergies and utilise recyclates more efficiently.

► Promotion of research and development:
Investments in new recycling technologies and processes should be prioritised to enable the processing of more complex plastic waste.
Adjustment of regulations

► More flexible quality standards:
Adjusting regulatory frameworks to facilitate the use of recyclates while ensuring product safety.

► Incentives for promotion:
Financial incentives for companies that use high proportions of recycled materials.
Awareness-raising and training

► Training programmes:
Development of training for the entire supply chain to improve the processing and utilisation of recyclates.

► Public outreach:
Raising consumer awareness of the benefits of recyclates to increase demand.
