Plastic recycling can be confusing, and it's important to know what types of plastic can be disposed of and in which ways. Most recycling centres accept plastics #1 and #2, which are typically PET and HDPE, respectively. PET is used to make bottles for soda, water, and other drinks, as well as cooking oil containers and plastic jars. HDPE is used to make milk jugs, shampoo bottles, detergent bottles, and other similar containers. These two types of plastic are the most consistently recycled due to their economic viability.

HDPE milk jugs are labelled as number 2 in the recycling triangle
Plastic products are often stamped with a resin code, a number between one and seven inside a small triangle made of arrows. The number inside the triangle indicates the type of plastic the product is made of. HDPE (high-density polyethylene) is a versatile plastic with many uses, especially in packaging. It carries a low risk of leaching and is readily recyclable into many types of goods. It is one of the easiest plastic polymers to recycle and is accepted at most recycling centres worldwide.
HDPE is used to make milk jugs, shampoo bottles, cleaning product containers, detergent bottles, motor oil bottles, trash bags, shopping bags, and butter and yogurt tubs. HDPE products can be recycled and are labelled with the number 2 in the recycling triangle.
It is important to note that while HDPE milk jugs can be recycled, consumers should always check with their local municipality to confirm that this type of plastic is accepted in their community's recycling program. Some areas may have specific guidelines or restrictions on recycling certain types of plastics.
Additionally, it is recommended to properly clean and dry HDPE plastic products before recycling them. This ensures that any residue or contaminants are removed, increasing the likelihood of successful recycling and preventing issues such as tangling in the recycling machinery.

HDPE is one of the easiest plastic polymers to recycle
High-density polyethylene (HDPE) is a plastic polymer that bears the recycling number 2. It is one of the easiest plastic polymers to recycle. HDPE is a popular plastic type due to its strength and flexibility. It is commonly referred to as polyethylene but is distinct from low-density polyethylene (LDPE). LDPE is used to make plastic bags, which can be recycled but often aren't due to the risk of tangling in recycling machinery.
HDPE is accepted at most recycling centres worldwide. It is one of the few polymers that can be recycled into the same form, such as new beverage bottles. The recycling process for HDPE involves sorting, cleaning, separating, shredding and melting, and creating new products. HDPE can be recycled into new pipes, crates, film, plastic lumber, and even recycling bins.
HDPE is used to make a variety of products, including milk and shampoo bottles, detergent bottles, pipes, and wheelie bins. It is important to recycle HDPE to help protect the planet and reduce plastic waste. Despite its durability, HDPE can be successfully recycled. However, it should be recycled separately from other types of plastic.
While HDPE is widely recyclable, the recycling rates vary across different regions. For example, in the US, the recycling rate for HDPE bottles is around 30%, while in the UK, only about 12% of HDPE plastic bags and 28% of HDPE water and milk bottles are recycled. These rates highlight the need for continued efforts to improve HDPE recycling practices and infrastructure.

HDPE can be recycled back into bottles or used to make new products
HDPE, or High-Density Polyethylene, is a type of plastic that can be recycled back into bottles or used to make new products. It is one of the easiest plastic polymers to recycle and is accepted at most recycling centres worldwide. The recycling rate for HDPE bottles in the US, for example, is around 30%.
HDPE is a strong, hard-wearing plastic with high tensile strength, making it resistant to tearing or bursting. It is also lightweight, non-corrosive, and flexible. These properties make it a popular choice for manufacturing bottles, particularly for milk, fruit juice, and detergent. It is also used for pipes, cans, crates, wheelie bins, and other plastic objects that may be used outdoors.
When recycled, HDPE can be used to create new products such as plastic lumber, tables, roadside curbs, benches, and other durable plastic products. It can also be recycled back into bottles, as HDPE can be transparent or pigmented (coloured). The two largest volume applications for recycled HDPE are extrusion blow moulding (bottles) and extrusion (pipe).
HDPE can be recycled up to ten times, significantly extending the material's life if properly recycled. Recycling HDPE is beneficial as it saves resources, water, energy, and landfill space, as well as reducing pollution. It is important to note that while HDPE can be recycled, it is still a plastic that contributes to environmental issues, and there is pressure on manufacturers to use recycled pellets to create new products.

HDPE can be downcycled into plastic lumber, tables, and benches
High-density polyethylene (HDPE) is one of the most common variations of plastic. It is used in bags, bottles, containers, and even furniture. HDPE is also one of the easiest plastic polymers to recycle. In fact, it is the most widely recycled plastic in the world. HDPE can be recycled into plastic lumber, tables, and benches through a process called downcycling, which involves reusing materials for lower-value products.
Downcycling is a practical solution to recycling HDPE, as it gives new life to plastic waste. The process begins with collecting HDPE products, such as milk jugs, detergent bottles, and other plastic containers, and sending them to large facilities for processing. The plastic is then cleaned and decontaminated to remove any food residue, adhesives, and paper. This rigorous process ensures the recycled plastic achieves a high purity level.
Following the cleaning process, the HDPE material is compounded into a rigid board stock material known as recycled plastic lumber or poly lumber. This recycled plastic lumber is an environmentally friendly alternative to wood. It is sturdy, low-maintenance, and resistant to degradation from sun, wind, moisture, and foot traffic. By using recycled plastic lumber, we can reduce our reliance on unsustainable logging practices.
The recycled HDPE plastic lumber is then crafted into various products, including tables and benches. These pieces of furniture are nearly indestructible and can be used to create aesthetically pleasing and functional outdoor spaces, such as patios and parks. They are also long-lasting, with the potential to look new for over a decade.
While HDPE downcycling has its benefits, it is important to acknowledge that it is not the only recycling practice. Upcycling, for instance, involves creating products of higher value than the original material. Additionally, despite the recyclability of HDPE, not all plastic types are recyclable, and financial barriers can hinder the recycling process. Nevertheless, HDPE downcycling into plastic lumber, tables, and benches remains a sustainable practice with the potential to reduce our environmental impact.

HDPE products can be recycled by most centres worldwide along with number 1 plastics
HDPE, or High-Density Polyethylene, is a type of plastic that is widely accepted at recycling centres worldwide. It is considered one of the easiest plastic polymers to recycle. HDPE products are commonly used in our daily lives, such as milk jugs, shampoo bottles, cleaning product containers, and detergent bottles.
HDPE recycling involves a few important steps. Firstly, it is essential to separate HDPE products from other waste types. This step is crucial as different types of plastics need to be processed differently. After separation, the HDPE waste is rigorously cleaned to remove any contaminants, ensuring the material quality is maintained.
The next step in the recycling process involves sorting the HDPE products into different categories, such as bottles, bags, tanks, films, offcuts, and sheets. This sorting step is necessary because the recycling machinery used for different forms of HDPE may vary. For example, HDPE film and plastic bags are recycled separately from bottles and thicker products to prevent them from getting caught in the machinery.
Once the HDPE waste has been sorted and cleaned, it is transported to a nearby waste management centre or large facilities to be processed and recycled into new plastic products. HDPE can be recycled into various items, including new pipes, crates, film, plastic lumber, and even recycling bins.
It is important to note that while HDPE is widely accepted at recycling centres, it is always good to check with your local authority or waste management guidelines to confirm. Additionally, it is recommended to ensure that all HDPE items are clean and dry before placing them in your recycling bin to prevent contamination.
HDPE products, identified by the recycling number 2, can generally be recycled alongside Number 1 plastics, which include PET or PETE products. These Number 1 plastics are commonly used for soda, water, and other drink bottles, as well as cooking oil containers and food jars. Both Number 1 and Number 2 plastics can usually be tossed into standard recycling bins, making it convenient for consumers to contribute to the recycling process.
