How PVC packaging is recycled in South Africa

PVC packaging is recycled into golf balls

Polyvinyl chloride (PVC) is one of the most common polymers used by plastics manufacturers in South Africa. It is used to manufacture irrigation pipes, medicine bottles, gumboots and so much more. However, PVC is more difficult to recycle than PET due to the chlorine content of the polymer.

Processing PVC plastics requires special machinery. Many small-scale recyclers in South Africa cannot process PVC, so plastics manufacturers have started to replace PVC products with PET. The one advantage of PVC is that it contains less carbon content than other thermoplastics.

PVC can be recycled up to eight times before becoming too brittle, depending on the application and the state of the plastic. It is also more energy-efficient to manufacture and process than other types of plastic. These characteristics make PVC a valuable polymer, especially when recycled properly.

Two methods of recycling PVC

There are two ways to recycle PVC; mechanical recycling by grinding it into small pellets which are then melted and remoulded into new products, or feedstock recycling where chemical processes break down the polymer into its basic chemical components. Both of these methods are used in South Africa but the mechanical recycling method is more common.

Unlike feedstock (chemical) recycling, mechanical recycling keeps the original composition of the PVC waste. This poses a problem because many PVC products contain additives and additional chemicals to make them rigid or flexible. For example, flexible PVC contains added plasticizers to increase the fluidity of the product. 

Even products used for similar applications may contain different amounts of additives, which makes mechanical recycling more difficult. PVC recyclate requires very specific compositions for different applications. In order to produce a high-quality recyclate, the PVC waste should be separated into uniform compositions before being mechanically processed.

This is where feedstock recycling has its advantages. By breaking down the recyclate into its basic chemical components, a mix of unsorted PVC products can be processed at the same time. However, feedstock recycling is more expensive than mechanical processing and the end-market for the recovered chemicals is not as big. This gives recyclers fewer incentives to use chemical methods to process PVC waste.

Post-consumer vs post-industrial PVC waste

The PVC waste that comes from post-consumer sources is often mixed in type and quality. On the other hand, PVC waste from post-industrial sources (factories) is often the same. This means that it is far easier to mechanically recycle the waste from post-industrial sources as it does not need to be sorted first. Post-consumer sources of waste require careful separation before being mechanically processed.

Post-industrial waste is relatively pure as it comes straight from the factories that produce one type of product (or products with similar chemical compositions). This waste is easy to collect and recycle since it comes directly from the source or the manufacturer and the quality is high. Post-consumer waste contains mixed materials that were used for various applications and the quality of the waste is often degraded.

PVC products are extremely durable – sometimes with a lifespan of over 50 years. The strength of this polymer lends itself to a lifetime of reuse, making PVC a valuable plastic. By reusing and recycling these products, we can maximise their usefulness while minimising their environmental impact.

PVC plastic successes in South Africa

PVC plastic gumboots

Polyvinyl chloride (PVC) is the fifth most-widely recycled polymer in South Africa. This plastic is strong, durable and can come in three forms – rigid, flexible and liquid. PVC is considered to be one of the most versatile thermoplastics and it is recyclable in South Africa. It can be recycled into numerous products, making it a valuable polymer for the economy.

South Africa has some of the highest recycling rates in the world – just under 21 000 tonnes of PVC plastic was recycled in 2018 alone. Of this volume, most of the PVC plastic came from gumboots, cables, hosepipes, plumbing pipes, conduit and gutters. These materials are mainly recycled into shoe soles, car mats and plastic speed humps.

PVC plastic recycling is a successful industry

PVC recyclate is currently in high demand due to its various applications and low energy requirements. This plastic is inherently flame-resistant and is impermeable to liquids. PVC is cost-effective to manufacture and, because of its versatility, it is an abundant plastic polymer. It is widely used in the construction, irrigation, medical, mining and motoring industry as a result of these properties.

PVC can also be recycled into various rigid, flexible and liquid products, including rubber shoes, flooring, trays, mats, insulation, raincoats and many more. The clothing and footwear industry purchases the majority portion of PVC recyclate, followed by the construction and agriculture sectors. This polymer has many uses as a recycled material in various industries in South Africa.

PVC has a number of beneficial properties

PVC is a popular plastic material because of its advantageous properties. During the manufacturing process, chlorine is obtained from ordinary salt and is chemically combined with ethylene, which is derived from coal in South Africa. PVC is always compounded with additives to give it a range of properties, such as rigidity, flexibility, fire resistance and liquidity. 

PVC has excellent resistance to wear and tear, making it ideal for products that need to withstand hard usage over many years. It is lightweight, cost-effective and requires little energy to manufacture. PVC is highly valuable in this regard as it supports economic development and the environment, unlike many plastic alternatives. These properties make PVC a popular plastic polymer. It is widely recycled in South Africa thanks to our strong and resilient recycling industry. For more information on South Africa’s vinyls industry, visit SAVinyls.co.za

Plastic packaging type 3 – PVC

PVC irrigation pipes

Plastics are highly-valuable materials that make modern life possible. These materials play vital roles in all aspects of life and are very beneficial to a number of industries. Plastic packaging is vital in the food, product manufacturing, medical, agricultural and financial sectors, to name a few. However, plastics need to be recycled properly in order to maximise their economic value and to minimise their environmental impact.

To understand more about plastics, we will shed some light on the different types of polymer, their benefits and their recyclability properties, including what products can be made from recycled plastic. We will go according to the material identification codes found on plastics. These are numerical symbols from one to seven that are used to identify the type of plastic.

This coding system is used around the world by recyclers. It enables them to separate and sort plastics so that they can be processed according to the main polymer present. All plastic packaging should display these material identification codes. The third polymer used for plastics is polyvinyl chloride (PVC).

What is PVC?

PVC is one of the most popular and oldest thermoplastic polymers in the world. It was discovered twice in the 1800s; first by Henry Regnault in 1838 and again by Eugen Baumann in 1872. PVC was first sold commercially by BFGoodrich in the 1920s. Most other polymers were only discovered in the 1940s and 1950s. 

There are three forms of PVC; rigid, flexible and liquid. The rigid and flexible variants are by far the most common form, having various applications in a number of industries. Rigid PVC is most commonly used in the irrigation and construction sectors, whereas flexible PVC is widely used in the medical and clothing industries.

Rigid PVC is used to manufacture irrigation pipes, conduit, gutters, pharmaceutical bottles, and fridge magnets. Flexible PVC is used to produce drip bags, electrical insulation, vehicle dashboard skins, gumboots, safety gloves, garden hoses and packaging films. The polymer is highly durable and cost-efficient to produce, requiring minimal amounts of energy.

Benefits of PVC

PVC has numerous unique characteristics that make it a valuable packaging and plastic material. It is highly resistant to environmental degradation, including wear and tear, chemicals and alkaline substances. It is cheap to produce and requires little energy in the process, making it an economically-beneficial polymer.

PVC has a high density and good tensile strength, especially the rigid form. This makes it a popular polymer for the construction and irrigation sectors, where the plastic needs to be able to withstand impacts and hard use. Its high resistance to chemicals and heat also makes it a valuable polymer. PVC is inherently flame-resistant and impermeable to liquids. 

All PVC pipes manufactured in South Africa have been lead-free since 2006 after local manufacturers belonging to the Southern African Plastic Pipe Manufacturers Association (SAPPMA) voluntarily, but at great cost to the industry, accepted a policy of heavy metal-free stabilizers for the manufacture of PVC pipes based on health and environmental considerations. 

As a member of the Southern African Vinyls Association (SAVA), SAPPMA is also one of the signatories of the Association’s Product Stewardship Commitment (PSC) a voluntary programme aimed at ensuring that all heavy metal additives (primarily lead) are removed from their workplace environments

These characteristics of PVC make it a versatile and highly useful plastic material. It is easy to recycle and is readily available, making it a valuable polymer for the recycling industry. All PVC plastic should be reused, upcycled or sent to a recycling facility when no longer needed. It should never be sent to landfills or dumped in the environment.

How PE-HD packaging is recycled in South Africa

Recycled traffic cone made from PE-HD packaging

High-density polyethylene (PE-HD) is a commonly used packaging polymer in South Africa. It is widely used to manufacture milk bottles, plastic crates, drums, irrigation equipment and cosmetic bottles. PE-HD is easy to recycle and has many beneficial uses – making it the third-most-popular packaging material in the country.

Most of the plastics used for packaging applications are mechanically recycled in South Africa. These materials are often picked, sorted and washed by hand before being processed. PE-HD follows a similar process when it is sent to a recycling facility to be turned into recycled plastic granules.

How PE-HD is recycled

Firstly, discarded PE-HD packaging is collected by waste management companies and informal waste pickers working at landfills. They source and collect the plastic before bailing them into bundles for transport. These bundles of PE-HD waste are then taken to recycling facilities where the process begins. 

The PE-HD bundles are undone and the plastic is separated by grade. Due to the many applications and products made using PE-HD, the waste will have various qualities. The plastic waste is cleaned thoroughly to remove any dirt, debris and contaminants. This makes the PE-HD refuse safe for processing and ensures that the recyclate batch is pure. Any contaminants or dirt could spoil the entire batch and ruin the quality of the end product.

The PE-HD waste is then fed onto a conveyor belt where it is sent to various stations in the recycling facility. The first stop is the granulator that shreds the plastic into smaller particles. These particles are sent to a high-temperature oven that melts them into a sort of resin. This PE-HD resin is extruded and cooled before being chopped into small pellets.

These pellets of PE-HD plastic are sold to manufacturers, who can then use them to create new products. PE-HD is commonly used for blow mould processes, so the pellets are melted into a sheet of soft plastic before being injected into a mould and shaped under pressure. Recycled PE-HD is used to manufacture numerous durable products, such as plastic toys, benches and crates.

PE-HD packaging can be reused in the home

This polymer is highly durable and can withstand a lot of wear and tear. Consumers should always aim to reuse their PE-HD containers and products before discarding them. Milk bottles can be washed and reused to store water and other liquids. Grocery bags made from PE-HD can be used again and again when visiting the supermarkets. 

Household containers and shampoo bottles can be used to store various products in the home. The strength of this polymer lends itself to a lifetime of reuse, making PE-HD a valuable plastic, especially when it comes to packaging. By reusing these products, consumers can save a lot of money in the long run. If discarding PE-HD is necessary, at least it can be recycled easily and the end products are just as strong and durable.

PE-HD plastic packaging successes

PE-HD plastic spray bottle

High-density polyethylene (PE-HD) is the third most-widely recycled polymer in South Africa. This plastic is strong, scratch-resistant and non-toxic, making it ideal for use in the beverage and packaging industry. PE-HD is an abundant material and is quite easy to recycle in South Africa. It can be turned into numerous recycled products, making it a valuable polymer that can be reused again and again.

South Africa has some of the highest recycling rates in the world – 63 038 tonnes of PE-HD plastic was recycled in 2018 alone. Of this volume, most of the PE-HD plastic came in the form of milk bottles, plastic crates and plastic drums. These materials are mainly recycled into carrier bags for grocery stores and supermarket chains.

PE-HD plastic recycling is a successful industry

PE-HD recyclate is currently in high demand due to its durability. Although recycled PE-HD is not suitable for food contact applications (like the virgin polymer is), there is a great need for the recyclate in the agricultural industry. The main bulk of PE-HD recyclate is used to manufacture irrigation pipes, feeding troughs, fence poles and weather covers for the farming sector.

PE-HD can also be recycled into various flexible packaging products, including bin liners, recycled grocery bags and wood bags. The mining industry also accounts for a large portion of PE-HD recyclate, followed by the rigid packaging and construction sectors. This polymer has a variety of uses as a recycled material in various industries in South Africa.

PE-HD has a number of beneficial properties

PE-HD is an ideal packaging material because of its unique properties. It is produced from the polymerisation of ethylene at high temperatures, making it dense and robust. It is a highly crystalline polymer with strong bonds between molecules. These properties make PE-HD a dense plastic with high strength, high temperature resistance and excellent chemical resistance.

PE-HD has excellent corrosion and scratch resistance, making it ideal for products that need to withstand wear and tear or contain harsh chemicals. It is a lightweight and non-toxic plastic that lends itself to many applications in the packaging industry and a number of other sectors. These properties make PE-HD a popular plastic polymer. It is widely recycled in South Africa thanks to our strong and resilient recycling industry.

Plastic packaging type 2 – PE-HD

Plastic milk bottles made from PE-HD

Plastics are valuable materials that make modern life possible, especially plastic packaging. These materials keep our goods protected and our food fresh. Plastic packaging even keeps medical equipment sterilised and safe from contamination. Plastics need to be recycled properly in order to maximise their economic value and to minimise their environmental impact.

To understand more about plastic packaging, we will shed some light on the different types of plastic, their benefits and their recyclability properties, including what products can be made from recycled plastic. We will go according to the material identification codes found on plastics. These are numerical symbols from one to seven that are used to identify the type of plastic.

This coding system is used around the world by recyclers. It enables them to separate and sort plastics so that they can be processed according to the main polymer present. All plastic packaging should display these material identification codes. The second polymer used for plastic packaging is high-density polyethylene (PE-HD or HDPE).

What is PE-HD?

PE-HD is a hard and strong form of polyethylene that is used to manufacture milk bottles, fruit juice bottles, plastic drums, buckets, crates, bins and shampoo bottles. PE-HD is widely recycled in South Africa and has some of the highest recycling rates. Its strength and durability make it ideal for products and packaging that need to withstand wear and tear.

PE-HD was the third-most recycled polymer in South Africa during the last financial year. Over 63 000 tonnes of PE-HD were processed in South African recycling facilities in 2018 alone. This plastic is in high demand by recyclers as it is used to manufacture recycled carrier bags for supermarkets and stores around the country. 

Benefits of PE-HD packaging

PE-HD has numerous unique characteristics that make it a valuable packaging material. It differs from normal polyethylene because it has a higher molecular weight which makes it heavier per volume – denser than conventional polyethylene. All polyethylene polymers have a whitish colour and are semi-crystalline, but PE-HD is more rigid and durable.

It is ideal for manufacturing thermoformed plastic moulds, just as milk bottles, buckets and helmets. PE-HD is very resistant to high temperatures; it does not melt easily. This makes it ideal for containers that carry hot liquids, such as kettles and pipelines. This polymer also has extreme cut and wear resistance, making it one of the most durable packaging plastics available.

PE-HD is highly resistant to chemicals, too. It is non-toxic and non-reactive, so it can be used in the food and beverage industry to store produce. This polymer has many uses, from packaging and agriculture to construction and homeware. These characteristics and benefits make PE-HD one of the most valuable plastic packaging materials in the world.

How PET packaging is recycled in South Africa

PET packaging identification code on bottom of water bottle

Polyethylene terephthalate (PET) is a common packaging polymer around the world. In South Africa, it is widely used to manufacture beverage bottles, vegetable punnets, yoghurt cups and even clothing. PET is easy to recycle and has many beneficial uses – making it the second-most popular packaging material in the country.

Most of the plastics used for various packaging applications are mechanically recycled in South Africa. These materials are often picked, sorted and washed by hand before being processed. However, PET is different. Owing to the volume of PET recyclable waste in South Africa, many recycling facilities use technology to sort and process this polymer.

PET is recycled using automated technology

Discarded PET packaging is collected by waste management companies and informal waste pickers working at landfills. They source and collect the PET plastic before bailing them into dense packs for transport. These bundles of plastic waste are then taken to recycling facilities where the process begins. The bails are fed onto a production line that first passes under strong magnets to remove any metal contaminants.

Next, the PET plastic is fed to a hot washer that removes sand, dirt and oils. The labels on beverage bottles are also removed in this washer. These labels are collected and sent to another recycling production line. The cleaned PET packaging is then fed along a conveyor and scanned using high-speed optical sensors and infrared cameras to sort the waste. 

These sensors detect the type and colour of the PET waste, sorting it into batches of clear, green, brown and mixed colours. It is necessary to sort the plastic by colour as this results in a recyclate with consistent colours at the end of the process. If brown bottles were mixed with green ones, the batch would come out a dirty olive colour. 

Once sorted by colour, these bails of recyclate are sent to a granulator to be turned into small flakes. These flakes are then washed in three stages to remove any residual contaminants and sticky label fragments. The flakes are sent to a heater, which dries them, before being fed to a high-temperature oven to melt. This melted PET resin is extruded (stretched into long strands), cooled and chopped into small pellets. 

These pellets of plastic are sold to manufacturers, who can then use the recycled PET (rPET) to create new beverage bottles. These rPET fibres are also used to manufacture a variety of products, such as polyester clothing, carpeting, underbody shields for vehicles and recycled PET packaging products.

Other methods of recycling PET packaging

The Coca-Cola Company is trying to find more sustainable ways of recycling its PET bottles. It has started to chemically recycle its plastic bottles. This process breaks the polymer down into its basic molecules, separating the colourants, contaminants and impurities at the same time. The result is a number of near-pure products that can be processed back into PET packaging or used for other applications.

While this chemical recycling process is only being trialled in Europe, it could make its way to South Africa in the near future. Right now, South Africa has some of the highest recycling rates in the world – beating Europe by over 15%. PET is one of the easiest plastics to recycle and it can be processed again and again. This has numerous economic and environmental benefits if the plastic waste is disposed of responsibly.

PET plastic packaging successes

PET plastic water bottle

One of the most common plastic packaging polymers is polyethylene terephthalate (PET). This plastic is highly durable and naturally colourless – making it ideal for protective food, beverage and product packaging. It is also easy to recycle and can be turned into numerous recycled products, adding to its popularity across the globe.

South Africa has some of the highest recycling rates in the world – 74 328 tonnes of PET plastic was recycled in 2018, making it the second most recycled polymer in the country. PET is so easily recycled in South Africa that we imported 5136 tonnes from foreign countries last year to boost the local recycling industry.

PET recycling is a successful industry

PET packaging is recycled into plastic fibres that are then sold to suppliers who manufacture various products. This recycled PET (rPET) is used to make plastic vehicle components, clothing, textiles and more packaging materials. Clothing and footwear account for one of the largest market segments for rPET; just under 15% of all rPET is used to manufacture polyester fibres for clothing and shoes.

The South African plastics industry has invested heavily in rPET. Post-consumer PET packaging and beverage bottles are also recycled into new plastic bottles, plastic sheeting and thermoformed punnets for food. rPET is the only recycled material that can be used in food-contact applications because it is 100% non-toxic and will not contaminate food and drinks with chemicals.

PET has a number of beneficial properties

PET is an ideal packaging material because of its unique properties. It is virtually shatterproof, which means that it forms a durable protective coating around food and products. It is also non-reactive and non-toxic, so food and products will not be contaminated by the packaging. 

PET is also very cost-effective to produce and recycle. These properties of the polymer make PET an unbeatable material for consumer product packaging and polyester clothing fibres. It is widely recycled across the globe, but even more so in South Africa thanks to our strong and resilient recycling industry.

Plastic packaging type 1 – PET

PET plastic bottle

Plastic packaging is a valuable part of any product, whether it is food, electronics, household goods or medicine. The packaging keeps the product safe and fresh, ensuring that it remains in perfect condition until opened. The manner in which society disposes of these materials is important; plastic packaging should be recycled wherever possible.

To understand more about plastic packaging, we will shed some light on the different types of plastic, their benefits and their recyclability properties, including what products can be made from recycled plastic. We will go according to the material identification codes found on plastics. These are numerical symbols from one to seven that are used to identify the type of plastic.

This coding system is used around the world by recyclers. It enables them to separate and sort plastics so that they can be processed according to the main polymer present. All plastic packaging should display these material identification codes. The first polymer used for plastic packaging is polyethylene terephthalate (PET).

What is PET?

PET is one of the most common polymers used for plastic packaging. It is mainly known for its use in the food and beverage industry. PET is used to make carbonated drink bottles, water bottles, plastic jars, vegetable punnets, food trays and strapping tape. It is also used in the textile industry (known as polyester). PET is a strong and durable plastic that can be flexible if stretched thinly. 

PET is widely recycled in South Africa – it has some of the highest recycling rates of any polymer, due to the sheer volume of products and packaging made from PET and its ease of processing. Over 74 300 tonnes of PET were recycled in South Africa during the last financial year and these rates have been steadily increasing for the past five years.

Benefits of PET packaging

PET has numerous important characteristics that make it a valuable plastic. It is a naturally colourless and non-toxic, which means that it is ideal for use in the packaging industry as it allows consumers to see the product contained within and it does not contaminate products. It can also be easily dyed, as some beverage manufacturers do with their green or brown bottles to resemble glass bottles.

PET is impermeable to liquids, which means that it is perfect for storing drinks under pressure. It also has a high strength to weight ratio, making it ideal as a protective packaging material. It will not shatter like glass jars and bottles, so PET is the most common replacement for these fragile packaging materials.

Due to its lightweight nature, PET is highly economical. Less polymer is needed to create the packaging as it is strong. This results in cheaper transport costs and less energy needed for the manufacturing of PET plastic. It is a widely recycled polymer because it can retain most of its strength and flexibility characteristics after being processed. This makes recycled PET (rPET) a readily-available and inexpensive material. These characteristics and benefits make PET one of the most common plastic packaging materials in the world.

Plastic packaging alternatives may be worse for the marine environment

Plastic packaging alternatives may be worse for the marine environment

A committee of United Kingdom members of parliament (MPs) has warned that plastic packaging alternatives could be doing more harm to the marine environment than plastics. Compostable and biodegradable plastics could be adding to global marine pollution because they do not always break down as intended.

The use of these plastic alternatives is growing rapidly around the world, but there is a worldwide shortage of infrastructure to correctly process these waste items. Experts also argue that the lack of consumer understanding about compostable and biodegradable plastics actually increases the likelihood of littering and illegal dumping.

Most compostable packaging waste needs to be sent to an industrial composting facility in order to properly decompose. Being left out in the environment will not work. The same goes for biodegradable plastics – they need to be sent to a certified facility in order to break down as intended. The MPs state that there are not enough of these facilities around the world.

Environmental NGOs weigh-in

These concerns held by British lawmakers are also shared by environmental non-government organisations (NGOs) in many regions across the globe. They agree that the rapid introduction of so-called biodegradable plastic alternatives may have actually increased marine pollution. “If a biodegradable cup gets into the sea, it could pose just as much of a problem to marine life as a conventional plastic cup,” says Environmental Investigation Agency ocean campaigner Juliet Phillips.

Environmental think tank, Green Alliance, also says that there is evidence to prove that the term ‘biodegradable’ makes consumers think that it’s alright to discard these materials into the environment. This inadvertently encourages pollution on land and at sea. These materials also do not decompose the same way in the environment as they did under controlled circumstances in a laboratory during development.

Governments concerned about plastic alternatives

“In the backlash against plastic, other materials are being increasingly used as substitutes in food and drink packaging. We are concerned that such actions are being taken without proper consideration of wider environmental consequences, such as higher carbon emissions. Compostable plastics have been introduced without the right infrastructure or consumer understanding to manage compostable waste,” says United Kingdom chair of the Commons select committee Neil Parish.

“The drive to introduce bioplastics, biodegradable plastics and compostable plastics is being done with limited emphasis on explaining the purpose of these materials to the public or consideration of whether they are in fact better from an environmental perspective than the plastic packaging they replace,” explains UK-based independent environmental charity, Keep Britain Tidy.

South Africa in the same boat

Although these opinions are being voiced by UK-based experts, they hold true for biodegradable and plastic alternatives around the world. South Africa is also seeing a rapid increase in the use of compostable and biodegradable plastics. Many supermarkets, coffee shops and restaurants are already providing South Africans with biodegradable and compostable alternatives.

These materials are also not always suitable for recycling. South Africa has a thriving recycling industry and many of the plastic materials produced in the country end up being recycled into new products over and over again. In a country like ours, it sometimes makes more sense to recycle traditional plastic packaging and products than to push for so-called biodegradable and compost alternatives.
