Chemical recycling (Chemcycling)

Re-use

Mechanical recycling

• Less colors by design• Less plastics to color• Purer and more stable colors • Migration resistant colorants• Carbon black hinders waste sorting

• Pyrolysis: No change vs State of Art• Depolymerisation:

• Carbon Black hinders waste sorting• Extractable colorants

• Less plastics• Better colorants

New-cycling (Selective polymer dissolution)

• Extractable colorants • Purer colors

• No waste imports / exports• Recycling as the norm

Trends in Plastics Industry Affected by Sustainabil ity Needs

Automotive

E-mobility / E-efficiency

• Light weight• More design & comfort • NIR Light management

Design & Functionality

• More plastics, colors

• Low VOC, low odor colors

• Low heat build-up colors

• No hazardous colors

Fibers & Textiles

Sustainable Fibers

• Bath mass dyeing• Competing materials• Certified consumer safety

Smarter, Purer coloring

• Increase PET vs PP

• Purer, Safer colors

• Smart coloring techniques

Packaging & Consumer Goods

Circular & Safe

• More re-use / recycle• Safety: a must !• Color sells !

Less color: Purer, Safer

• Less prime vs more scrap

• Partially ban Carbon Black

• 3D printing emerge

• Consumer Safety

Building & Construction

Green Buildings

• Durability• Energy efficiency• Functionality

Sustainable, durable

• Continued use of durable
