PET & rPET

We use PCR PET

We use Post-Consumer Recycled (PCR) PET* in our bottles and jars production, which is the more sustainable option in comparison with Industrially-recycled PET.

*PCR means the PET has been used by a consumer previously and then has been directly recycled or been removed from the environment.

 

 

Full traceability

All raw material blend proportions are recorded automatically at our blending station and are managed in accordance to
ensure the full traceability from raw material to final products.

 

 

Quality certifications included

Quality Certificates are provided with each production batch – this details the exact percentage of PCR PET material in each item.

 

 

PCR is in high demand

Recycled plastic has increased in demand, therefore we are working with many PCR PET suppliers.
All of them have EFSA approved cleaning technologies and supporting documentation of conformity.

 

 

Variations in appearance

Different cleaning technologies and consumption habits cause variations in appearance and shades.
Spots or shades of grey/blue/yellow can appear in recycled products and the appearance of PCR PET-based products can vary
from batch to batch. This is just a visual effect and does not affect the usability of the bottle or jar.

Learn more about PET

PET (or PETE, PETP, PET-P, Virgin PET) is polyethylene (or polythene) terephthalate. A form of polyester, it’s a plastic resin made from a combination of two monomers, ethylene glycol, and purified terephthalic acid.

Virgin PET is made through crude oil and natural gas extraction from the Earth’s core. It is heated to form a molten liquid then moulded and solidified to create PET plastic containers.

It is the most recycled plastic worldwide because so many waste management systems accept it. PET is also easy to identify for recycling through clear embossment and good labelling. It is regularly used for soda bottles, water bottles, and food jars.

Bi-axial stretch

Through both stretching and blowing, the rPET is moved in two directions. This method is responsible for giving rPET it’s glass-like clarity while having excellent barrier properties and strength.

Intrinsic Viscosity (IV) in PET

IV is the measure of the polymers molecular weight which indicates the strength and functionality of the PET. The higher the IV, the better the tensile strength, the higher the melting point, and the lower the freezing point, so a high IV is best.

 

Qualities and benefits of PET bottles and jars

The following qualities and benefits of using PET are also all applicable to rPET, bar one: 100% pure rPET bottles may have a slightly cloudy appearance due to impurities and a lower IV. This could be an acceptable trade-off for consumers, but if not, it can be easily corrected by using a slightly less sustainable mix of rPET and PET.

 

  • Shatterproof: making them ideal for use in surroundings where glass can be a potential hazard, like bathrooms, kitchens, and retailers, and perfect for on-the-go consumption
  • Good Barrier properties mean a longer shelf-life: PET packaging has excellent gas and moisture barrier properties and is resistant to penetration from microorganisms and O2, meaning it can keep food and beverage and products containing oxygen or carbon dioxide, alcohols, oils, and diluted acid fresher for longer when compared with other plastics
  • Lightweight: 10% of the weight of the equivalent glass packaging meaning it is convenient to use and incredibly efficient to transport, therefore lowering carbon emissions
  • Transparent: with the same clarity and appeal as glass packaging to display contents
  • Thermostable: most common cold-fill PET bottles and jars can withstand temperatures from -40 to 60degrees. If using CPET or a double ISBM process it is possible to make hot-fill bottles that can withstand the heat of a conventional oven up to 230degrees celsius. PET also has a higher heat distortion temperature (HDT) than other plastics
  • Reusable, resealable, and fully recyclable: the bottles and jars can be reused and the polymer can be reprocessed to granulate and reinserted back into its original supply chain to create new PET feedstock
  • Easy to recycle: widely accepted by recycling plants across Europe, and easy to distinguish with the #1 recycling embossment and label: 90% of Virgin PET has been recycled in countries such as Finland.
  • More sustainable than other plastics: PET has a lower manufacturing carbon footprint than other plastics
  • Customizable: Especially with the Single-Stage injection blow moulding process it can be formed into many non-circular shapes and varying volumes
  • Inexpensive: there is a high supply of PET and so it has a lower cost than other plastics

 

PET vs. Glass

Pros 

  • PET is up to 40x lighter than glass
  • PET is 5x less expensive than glass
  • PET is more durable than glass due to being shatterproof
  • PET is safer as it doesn’t grow microbial biofilms including bacteria, fungi and protists that are very bad for health like glass does
  • PET manufacturing process is better for the environment than glass production

Cons 

  • Glass can be clearer, although high-quality PET can have a glass-like look
  • PET extracts crude oil from the ground whereas glass uses sand

Analysis shows that the overall environmental impact of PET as a packaging material is lower, and this is mostly due to the weight of glass. PET is much lighter and uses far less CO2 to transport. Furthermore, PET is fully recyclable (like glass) and it doesn’t break so the production leads to a much higher level of used products and far fewer breakages/damages.

 

PET vs. Aluminium

Pros 

  • PET uses half the amount of greenhouse gases to produce than aluminium, with a 330ml PET bottle using 330g vs. an aluminium can of the same size using 1300g of CO2 emissions
  • PET costs 20-30% less than aluminium
  • PET is more consumer convenient as it is resealable, whereas cans cannot be closed
  • PET has more options for shapes, volumes, and colours
  • PET production has more existing infrastructure set up, therefore costs less to produce than cans which have less

Cons 

  • Less power is needed to chill aluminium cans than PET bottles
  • Less space needed to transport aluminium cans than PET bottles due to their being so lightweight

PET is a far more sustainable choice when considering the CO2 emissions produced by Aluminium production, the food and beverage waste that can occur from non-resealable packaging, and the cost of changing a lot of manufacturing infrastructure.

 

What is rPET?

rPET is recycled polyethylene terephthalate. The key impact of rPET is in its creation – reducing greenhouse gas emissions by 71% when compared with Virgin PET and requiring 79% less energy to produce. This gives rPET a far smaller carbon footprint, at under a quarter of regular PET, 0.45 of CO2 per kg vs. 2.15 CO2 per kg. rPET bottle and jar production grew by 29.5% in 2017.

rPET is produced by collecting and sorting industrial waste and post-consumer PET, refining the material into flakes, then cleaning and drying them to form a granulate that can be turned into new products. rPET can be produced in two ways:

Post-Consumer

Means PET that has been used by consumers before being disposed of. It can be collected from recycling bins, the ocean, or landfill. Post-Consumer recycling is effective in removing plastic from the environment and reprocessed to form rPET.

Post-Industrial

Is the PET that is collected as waste during the manufacturing process. This can be reused, making manufacturing more efficient and sustainable. It is also reprocessed to form rPET.

 

The benefits of rPET

rPET has all of the benefits of PET bottles and jars, with some added extras. From a business perspective, introducing more rPET into packaging means a business can identify with a broader customer base and increase sales by meeting the demand for recycled packaging and sustainable efforts. In addition, rPET use leads to greater demand and market for recycled plastics which will increase material supply and lower costs – a win-win for business and the environment.

In addition to having all of the benefits of pure PET bottles – rPET has many environmental gains:

  • Uses 79% less energy plus less water to produce than virgin PET
  • Reduces transport carbon emissions: as demand grows, there is also a more local and reliable supply of rPET, limiting the need to transport rPET internationally
  • Less plastic going to landfill: through recycling and stopping the material entering landfill, no toxic chemicals are leaching into the groundwater during the years that they can take to break down
  • Reducing the need to extract resources from the earth, using rPET offsets the need to create new PET
  • Encouraging bottle return schemes and post-consumer recycling programs and establishing them as a norm within the industry – less likelihood of plastic waste ending up in the ocean
  • Lowering costs – the consumer demand for recycled materials has risen and so is pushing the prices and transport costs down, plus a focus on good design means lowering costs and waste through reducing the amount of plastic used during the bottle and jar production process
  • Fulfilling consumer demand for recycled packaging, increasing sales, and lowering costs through progressing the market of recycled materials
