A sustainable alternative to Carbon Black: A new solution for sorting and recycling of black plastic products making our circular economy better
- Black plastic can be recycled like most other recyclable plastics.
- However, the pigments based on carbon black cannot be detected by traditional optical sorting methods used in most material recovery facilities, which separate plastics into different polymer streams.
- Carbon black, even in very low concentrations, absorb light in the near infrared (NIR), meaning no light is reflected back into the NIR detectors for identification.
- The result is that black plastic ends up as unsorted residue destined for landfill.
Kafrit’s black MB, CC 90778 LL BLACK, which is a non NIRabsorbing alternative, was developed and optimized to enable sorting and recycling of black plastic products.
Properties
- High tinting strength and opacity
- NIR-reflectivity at any concentration
- Extremely heat resistant in all plastics even after multiple processing steps
- Compliant with AP (89) 1 , EN 71 – 3,94/62/EEC and CONEG regulating heavy metal content
- Food contact compliant (EU, Japan)
- Non migrating, no PAA release
Applications
- Use as main shade black or as shader
- Polyolefins and Engineering plastics (PA, PET, PC…)
- All black or colored plastics from Food packaging to industrial goods
- Suitable for micro-wave and oven heated food trays
Sustainability benefits
- Sustainable alternative to carbon black
- Enables all blacks and colorful formulations to be sorted and therefore recyclable
- Allows multiple product life cycles through mechanical recycling
- Opens options for closed loop recycling (not degrading, durable)
