Plastic Recycling: Why Blue Plastic Is Special

Plastic waste is a pressing issue for governments, environmentalists, and organizations worldwide. Plastic can take up to 1000 years to biodegrade, polluting the environment and taking up landfill space. While recycling plastic is critical to improving the environment and waste management, not all plastic is widely recyclable. The recyclability of plastic depends on its resin type, ranging from 1 to 7, with 7 being 'other'. So, is blue plastic recyclable?

Blue plastic bottles are recyclable

The process of recycling plastic bottles typically involves sorting the plastic by resin type and color, followed by mechanical or chemical recycling methods. Mechanical recycling includes washing, grinding, and melting the plastic, while chemical recycling breaks down the plastic into monomers to form new polymers. Recycling plastic is crucial for the environment as it can take plastic up to 1000 years to biodegrade, causing pollution and taking up landfill space. Recycling plastic can also help conserve natural resources and energy, as plastic is made from oil.

It's important to properly prepare plastic bottles for recycling by rinsing them and ensuring they are free of food residue and completely dry. It's worth noting that local recycling programs may have specific guidelines on what can be recycled, so it's always a good idea to check with your local program. Additionally, some plastic bottles, such as those that have come into contact with motor oil or hazardous materials, may not be accepted for recycling and require special disposal methods.

While recycling is an important part of the solution, it's also crucial to address the root cause of plastic pollution by reducing plastic consumption and properly disposing of plastic waste. This includes avoiding single-use plastics and supporting the development of better, more recyclable products. By combining recycling efforts with a conscious approach to plastic use, we can make a positive impact on the environment and contribute to more sustainable practices.

Blue plastic is sorted by resin type

Blue plastic, like all other plastics, is sorted by resin type, either manually or using mechanised automated processes, or even by colour. The numbers attributed to plastics are the plastic resin codes, which quickly show which type of plastic a product is. The numbers range from 1 to 7, with 7 being 'other'. The general rule of thumb is, the lower the resin code, the more likely the plastic type is to be easily recyclable. Many plastic types can be recycled, even if the process is not widespread, however, many plastics aren't recycled simply because they aren't easily recyclable.

The difference in the recyclability of plastic types can be down to how they are made; thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled, whereas thermoplastics can be re-melted and re-molded. Examples of non-recyclable plastics include bioplastics, composite plastic, plastic-coated paper, and polycarbonate.

HDPE is accepted at most recycling centres in the world, as it is one of the easiest plastic polymers to recycle. Recycling companies will usually collect HDPE products and send them to large facilities to be processed. In the US, the recycling rate for HDPE bottles is around 30%. Just like PET, HDPE can be transparent or pigmented (coloured). The primary markets for post-consumer recycled natural HDPE include non-food application bottles, such as detergent, motor oil, and household cleaners.

Oftentimes, HDPE is also downcycled (a recycling practice that involves materials' reuse for lower-value products) into plastic lumber, tables, roadside curbs, benches, and other durable plastic products. PET is the most widely recycled plastic in the world and is usually recycled into fashion items like polar fleece clothes, backpacks, and carpets.

Blue plastic bags are not recyclable

Plastic waste is a major environmental concern, with the majority of plastics disposed of in non-environmentally friendly ways. Plastic can take between 500 to 1000 years to biodegrade, so recycling plastic is critical to improving the environment and bettering waste management solutions. However, not all plastic is widely recyclable, and blue plastic bags are a prime example.

Another issue with blue plastic bags is their colour. Before being recycled, plastics are sorted according to their resin type and colour. The presence of blue pigment in the plastic bags can complicate the recycling process, as the colour may need to be removed or altered to create a recycled product. This adds an extra step and cost to the recycling process, making it less likely to be undertaken.

Furthermore, blue plastic bags are often contaminated with food residue or liquids, which can render them non-recyclable. Even if they are rinsed, it can be challenging to ensure they are completely free of residue, and contamination can impact the quality of the recycled material. This contamination issue is particularly relevant to plastic bags, as they are frequently used for grocery shopping and can come into contact with food items or leaks.

The non-recyclability of blue plastic bags highlights the broader challenges in plastic recycling. While recycling is essential for environmental conservation, many plastics are not easily recyclable or are not accepted by local recycling programs. It is crucial for individuals to check their local recycling guidelines and to reduce plastic consumption and disposal where possible.

Blue plastic food containers are not recyclable

Plastic waste is a key concern for environmentalists, governments, and organizations, as the majority of plastics are disposed of in non-environmentally friendly ways, resulting in polluted oceans, overextended landfills, and ecological damage. While recycling plastic can be beneficial for the environment, not all types of plastic are recyclable.

Blue plastic food containers, for example, are not always recyclable. This is because plastics are sorted according to their resin type and color before being recycled. The resin type is indicated by a number, usually ranging from 1 to 7, with 7 being 'other'. The lower the resin code, the more likely the plastic is to be easily recyclable. However, blue plastic often falls into the 'other' category, making it more difficult to recycle. Additionally, food containers can be challenging to recycle due to the presence of food residue, which can contaminate the recycling process.

Furthermore, some recycling centers may not accept blue plastic food containers due to the specific pigments or dyes used to create the blue color. These pigments or dyes can interfere with the recycling process, especially if the recycling center is only equipped to handle certain types of plastic resins. It's important to check with your local recycling program to confirm which specific types of plastic they accept.

Another challenge with recycling blue plastic food containers is that they often contain multiple types of plastic resins, which can be challenging to separate and recycle effectively. This is common in many plastic products, as they may be made from different types of plastic to enhance their performance or reduce costs. However, this mix of plastic resins can make it difficult for recycling facilities to process them effectively.

Lastly, blue plastic food containers may be made from a type of plastic that is not commonly recycled, such as bioplastics or composite plastic. These types of plastic often require specialized recycling processes or facilities, which may not be readily available in all locations.

It is important to note that the recyclability of plastic can vary depending on your location and the specific recycling infrastructure available. While blue plastic food containers may not be recyclable in your area, there may be other communities or regions that have the capacity to recycle them. Always remember to check with your local recycling guidelines to stay informed about what types of plastic are accepted in your community.
