For years, the sleek, professional appearance of black plastic has made it a popular choice for ready-meal containers and food packaging. However, this aesthetic appeal has come at a significant environmental cost. Despite being made from recyclable materials, the vast majority of black plastic ends up in landfills or incinerators. MCP's latest innovation directly addresses this challenge, merging high performance with genuine recyclability and a commitment to a circular economy.
The Black Plastic Recycling Challenge
The core of the problem lies within the sorting facilities that handle our recycling. These plants predominantly use near-infrared (NIR) spectroscopy to identify and separate different types of plastics. This technology works by shining infrared light on materials and reading the specific wavelengths that are reflected back, allowing sensors to identify the polymer type.
However, the most common pigment used to create black plastic is carbon black, which absorbs infrared light instead of reflecting it. This absorption makes the plastic essentially invisible to NIR scanners. As a result, even high-quality, recyclable black plastics like CPET (crystalline polyethylene terephthalate) trays are not detected on the sorting line. They are automatically rejected and diverted to residual waste streams destined for landfills.
A Problem of Scale
The impact of this technological limitation is significant. Black plastic is estimated to account for a substantial portion of the plastic waste stream, yet its recycling rate in most systems is negligible or close to zero. Studies and reports from across the UK, EU, and US confirm that while overall plastic recycling rates are already low, the rate for black plastic is far worse due to these sorting failures. For instance, in the US, where only about 8.7% of all plastics were recycled in 2018, the rate for black plastics is even lower. In the UK, despite the majority of local authorities collecting food trays, most black trays are still not ultimately recycled.
This gap between technical recyclability and actual recycling has made black plastic a major target for environmental initiatives, with calls from industry organizations to phase out undetectable carbon black from packaging.
MCP's Innovation: A Truly Circular Solution
Recognizing the urgent need for a solution, MCP has developed its new line of IR-Detectable Black rCPET Trays. This innovative product line uses a special, advanced pigment that is free of carbon black, allowing infrared light to be reflected and making the black trays fully visible to NIR sorting systems. This ensures that the trays can be correctly identified, sorted, and routed into the proper recycling stream with other PET plastics.
To make the product even more sustainable, MCP has engineered these trays to contain a significant percentage of Post-Consumer Recycled (PCR) material. By incorporating recycled plastic into the new trays, MCP reduces the demand for virgin resources, lowers the product's carbon footprint, and actively participates in building a circular economy.
High Performance Meets True Sustainability
MCP’s new trays prove that enhanced sustainability does not require a compromise on quality or performance. The IR-Detectable Black CPET Trays offer the same robust features that customers expect:
- Made with Recycled Content: Incorporating PCR material reduces the carbon footprint and supports a circular economy.
- Superior Durability: Ideal for a wide range of food products.
- Extreme Temperature Resistance: Safely usable from deep-freezing to conventional oven and microwave heating.
- Premium Aesthetics: The sleek, black look enhances product presentation on the shelf.
With this new product, MCP ensures that its partners can offer consumers a convenient and attractive packaging solution that is truly designed for a circular economy. By not only making black plastic recyclable but also using recycled content in its production, MCP is helping to close the loop, reduce landfill waste, and build a more sustainable future for packaging.
