Due to the diverse range of functions polypropylene (PP) can perform, it enters the waste streams from a number of different sources. It is commonly used in items such as medication bottles, drinking straws, bottle caps and packaging materials. Once its purpose has been served and the plastic is disposed of, it will be gathered by a waste management company and sent on to a recycler such as Pakire Polymers. Once the material arrives at the recyclers it will be segregated, cleansed, melted down and moulded into new plastic pellets. At Pakire we use industry leading EREMA technology to produce the highest quality of recycled plastic pellet on the market. These pellets can then be put back into manufacturing to produce any number of products from those listed above to automotive parts, battery casings, cable insulation, gardening equipment and many other options.
On products made from PP, especially food containers, there will often be the number 5 within a triangle on the bottom of the item. This number is to identify the material as polypropylene; the American Society for Testing and Materials (ASTM) Resin Identification Code (RIC) is a system designed to ensure that different polymers are easy to make distinct from each other. Under this system polymers are assigned numbers, 5 in the case of polypropylene, so that materials may be more easily divided into groups. Keeping polymer groups separate is a crucial part of the recycling process as it not only saves time but maximises the amount of plastic that can be recycled.

Other Materials We Recycle
Low-Density Polyethylene (LDPE)
As the name suggests, low-density polyethylene (LDPE) has a lower molecular density than other types of polyethylene.
High-Density Polyethylene (HDPE)
High-density polyethylene (HDPE) is the form of polyethylene in which the molecular structure is of increased density....
We Also Accept These Materials
PET Plastic Materials - Polyethylene Terephthalate (PET) is a thermoplastic formed by the combination of ethylene glycol and terephthalic acid. It is a popular choice in food and beverage packaging as it is a clear, strong and lightweight plastic; nearly all single-use plastic drinks bottles are made from this particular polymer. The uses of PET are not limited to drinks bottles; it is also frequently used in carpets, sleeping bags, automotive parts and many other products.
PVC Plastic Materials - Polyvinyl Chloride (PVC) is a thermoplastic synthesised by combining ethylene and chlorine. PVC is a highly versatile material and can be made into an array of products; it can be easily shaped and sets very hard, making it the perfect material for automotive parts or construction materials. With the use of additives, PVC can also be made very soft and flexible, making it ideal for products such as polyvinyl flooring or upholstery.
PS Plastic Materials - Polystyrene (PS) is a thermoplastic; it is a hydrocarbon polymer sequenced from the monomer styrene. PS is highly adaptable as it can come in the form of a solid plastic or a rigid foam. When solid, PS is a popular choice for items such as food and beverage packaging and laboratory ware. When mixed with colorants or additives it can also be used in parts for electrical appliances, gardening equipment and many other products. Foam PS will often be over 95% air and makes for an excellent insulant; therefore, it is a popular choice for insulating homes and appliances, as well as for products such as food packaging and even surfboards.
PC Plastic Materials - Polycarbonate (PC) refers to a group of thermoplastics that contain carbonate groups within their chemical composition. PC polymers are very strong, lightweight and are resistant to impact, heat and chemicals. The properties of PC make it suitable for a variety of products such as medical equipment, automotive parts, construction materials, food packaging and many others.
ABS Plastic Materials - Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic synthesised from the combination of three monomers: Acrylonitrile, butadiene and styrene. ABS is a very strong and stiff material with high levels of impact and corrosion resistance; it is regarded as being a particularly useful polymer in engineering. The properties of ABS make it an ideal choice for use in manufacturing products such as tools, plug sockets, electronics components and a variety of others.
EPS Plastic Materials - Expanded Polystyrene (EPS) is a thermoplastic sequenced from the monomer styrene. EPS is made by using steam to heat polystyrene (PS) beads, decreasing their density and allowing them to hold air in their interior. In order to prevent creating a vacuum when cooling the newly expanded beads, the rate at which the air is allowed to leave will be slowed using a process called air diffusion. The stabilised beads will then be placed into a mould and exposed to steam once again causing them to bind together and form the finished product. EPS is a very lightweight material and can be made very tough relative to its low density. This material is frequently used to store and transport fresh foodstuffs, as protective packaging materials for electronic items, in sports equipment and in furniture items.
