According to WRAP, around 30,000-60,000 tonnes of black plastic packaging enters the UK household waste stream each year, much of which is undetectable by the machinery used in recycling plants. The amount of black plastic use continues to grow, with no clear recycling option available.
Detection is the Key
The carbon black-based masterbatches and compounds used in black products make the base polymer undetectable by recycling facilities using near-infrared (NIR) spectroscopy technology. This means much of the commonly used PE, PP and PET black plastics from mixed-plastic household waste that could be recycled is missed and ends up in landfill.
