Black plastic bags are often not recycled due to the use of carbon black pigments
Carbon black is a commonly used pigment for dying packaging black. However, it is not recognised by the near-infrared scanners used for sorting recyclables. As a result, the plastic is not sorted and recycled. This issue is not unique to black plastic bags; all types of black plastic items, such as food and takeaway containers, may face the same fate.
To address this problem, some companies are minimising the use of carbon black plastic. For example, SC Johnson is transitioning to more recyclable materials, contributing to a more circular economy for plastic. Additionally, The UK Plastics Pact encourages packaging specifiers and manufacturers to use detectable colourants. They requested that members using black plastic switch to detectable black pigments by the end of 2019, allowing the waste to be sorted and recycled.
While progress is being made, it is important for consumers to be mindful of the recyclability of black plastic. Consumers can advocate for less carbon black plastic and choose products packaged in clear or light-coloured plastic, ensuring their plastic waste does not end up in landfills. Checking with local authorities is also advisable, as some areas may have specific guidelines or programs for recycling black plastic.
It is worth noting that plastic bags, in general, can be challenging to recycle due to their tendency to contaminate other recyclables and cause machinery issues at recycling centres. They are among the most common sources of marine debris and can harm wildlife. As such, it is crucial to reuse plastic bags whenever possible and properly dispose of or recycle them when necessary.

Near-infrared scanners cannot detect carbon black pigments
Black plastic bags are not always recycled due to the presence of carbon black pigments, which near-infrared (NIR) scanners cannot detect. NIR technology is commonly used to sort polymers, but it relies on the reflection of energy from the plastic to function properly. Unfortunately, carbon black pigments do not reflect NIR light, causing black plastic items to often end up in landfills.
Carbon black is a widely used pigment in black plastics, and it absorbs a significant portion of the ultraviolet and infrared spectrum. This absorption prevents the reflection of infrared light back to the NIR scanner's sensor, blocking the recognition of the resin's fingerprint. As a result, black plastic items are often not identified and sorted by recycling companies, contributing to waste.
To address this issue, some companies have developed carbon black-free masterbatch ranges that are NIR transparent. These products allow black plastic packaging to be scanned and sorted by NIR technology, facilitating the reuse, repair, and recycling of this waste stream. Such innovations support the transition towards a more circular economy, where resources are utilized more sustainably.
While black plastic bags can technically be recycled to create new dark-colored plastic items, the presence of carbon black pigments complicates the process. Consumers can play a role in reducing the environmental impact of black plastics by advocating for less carbon black plastic usage and choosing products packaged in clear or light-colored plastics, which are more easily recyclable.
It is worth noting that plastic bags, in general, pose challenges in the recycling process due to their tendency to tangle in machinery. As a result, some recycling programs and facilities may not accept them, and it is important to check with local guidelines before attempting to recycle plastic bags.

Black plastic can be recycled to make other dark-coloured plastic items
Black plastic is often used for packaging because it enables colours or imperfections to be masked. However, black plastic is commonly regarded as non-recyclable due to the use of carbon black pigments, which are not recognised by the near-infrared scanners used for sorting recyclables. This means that black plastics are often skipped during sorting and end up in landfills.
However, black plastic can indeed be recycled to make other dark-coloured plastic items. In recognition of this issue, The UK Plastics Pact has requested that members using black plastic switch to using detectable black pigments by the end of 2019. This new type of black plastic can be detected by lasers and is now widely sorted for recycling.
Despite this development, it is still recommended that consumers choose products packaged in clear or light-coloured plastic, as these are more easily recyclable. Consumers can also advocate for less carbon black plastic and ensure that any black plastic they use does not end up in landfills. Companies such as SC Johnson are also making efforts to minimise the use of carbon black plastic.
Overall, while black plastic can be recycled into other dark-coloured items, the process is complicated by the use of carbon black pigments, which are not easily detected by recycling technology. Consumers can play a role in reducing the environmental impact of black plastic by choosing alternatives when possible and advocating for change.

Some local authorities do not accept black plastic for recycling
Black plastic bags are not always accepted for recycling by local authorities due to the use of carbon black pigments, which are undetectable to special laser technology and near-infrared scanners used during the sorting process. This technology is used to sort different types of plastics for reprocessing. Since black plastic is often skipped during sorting, it ends up in landfills or is incinerated instead of being recycled.
To avoid this issue, some local authorities recommend that recyclables be placed loosely in bins rather than bagged. This allows for a more efficient sorting process and reduces the risk of contamination, as spills or non-recyclable items inside black bags may be missed and end up contaminating the rest of the recyclables.
In some cases, local recycling programs may specify the use of clear plastic bags for certain items, such as batteries and small electronics, to facilitate the identification and sorting process. However, it's important to note that plastic bags themselves can also be recycled through dedicated recycling programs offered by some retailers and organizations.
To ensure proper disposal of black plastic bags, it is recommended to check with your local authority or recycling program to understand their specific guidelines and requirements. Additionally, consumers can advocate for and choose products packaged in clear or light-colored plastic, which is more easily recyclable, and encourage businesses to adopt more sustainable packaging alternatives.

Clear plastic bags are preferred for recycling as they allow operators to identify contamination
Black plastic bags are generally not recycled due to the use of carbon black pigments, which are not recognised by near-infrared scanners used for sorting recyclables. This results in black plastic often being skipped during sorting and ending up in landfills.
Clear plastic bags, on the other hand, are preferred for recycling as they allow operators to easily identify contamination. This is especially important in the case of batteries and small electronics, where some local curbside recycling programs mandate the use of clear plastic bags. This enables workers to quickly detect and divert any potentially hazardous materials to landfills before they contaminate the rest of the recyclables.
Clear plastic bags also facilitate the identification of spills and other contaminants, ensuring they can be promptly removed from the recycling stream. This helps maintain the integrity of the recycling process and reduces the risk of contamination.
Additionally, clear plastic bags are recommended for donated textiles, as they allow for easy inspection and sorting of the contents without the need for machinery. This simplifies the process and ensures the donated items remain dry and protected.
While black plastic has traditionally posed challenges for recycling due to its invisibility to laser technology, there have been recent developments in creating a special type of black plastic that can be detected by lasers and recycled. However, clear or light-coloured plastic remains the preferred choice for recycling, as it ensures a higher likelihood of the material being recycled rather than ending up in landfills.
