Innovative bottle spacers treat asthma

Innovative bottle spacers to treat asthma

An innovative approach is set to make a huge impact on treating asthma in South Africa, made more critical during the coronavirus pandemic. Asthma treatment is usually given by an inhaler, but to get medication more effectively to the lungs in a crisis, the use of a spacer along with the inhaler, or a nebuliser is required.

 

Extraordinary times require extraordinary solutions.  The bottle spacer programme, pioneered at the Red Cross War Memorial Children’s Hospital in Cape Town aims at bridging the gap between expensive commercial spacers and the need in low income communities. The team has tested and evaluated the efficacy of using plastic bottle spacers, which are immediately available, instead of expensive spacers.

 

This plastic bottle spacer not only allows the medication to work much more effectively, but also has the added benefit of minimising droplets in the air and ultimately reducing the risk to staff and patients becoming infected with the coronavirus.

 

When one uses an asthma pump directly in the mouth most of the spray hits the back of the throat and does not go into the lungs.  A spacer is a chamber filled with air, with the asthma pump fitting into the back.  When you spray the pump first inside the chamber and then breathe this air into one’s lungs, the spray goes into the deepest part of the lungs where it is needed the most.

 

“Since Prof Heather Zar first pioneered bottle spacers back in the late 90s using a manual burning technique, we have been using them at the Red Cross War Memorial Children’s Hospital.  But from just a few hundred units a year, we needed to produce tens of thousands, to facilitate the large-scale use of spacers in the public health service across the country,” Prof Michael Levin, Head of Allergy at Red Cross and project lead, explains.

 

Polyoak Packaging partnered with Habitat industries to create a custom blow-mould base with an indentation in the shape of an asthma pump nozzle.

 

“During production when the bottle is blown and the plastic is still soft, air is blasted into the bottle base which creates the inhaler size extrusion. So, after that, the only small manual task is to slice off the end of the indentation leaving a perfect-fit attachment hole for the inhaler.  Polyoak has even been able to include the Allergy Foundation website address on the base of the bottle,” continues Prof Levin.

 

“This is an example of an innovative boundary spanning project which aims to bring a low cost clinically-effective solution to patients across the province, and potentially the country,” says Dr Anita Parbhoo, Medical Manager at Red Cross War Memorial Children’s Hospital.

Prof Mike Levin is excited about using the new bottle spacer

DOW joins Hands with PlasticsSA to ensure Clean Hands

Social distancing and good hygiene are two practices that are at the centre of the fight against COVID-19. Thousands of people living in Cape Town’s poorer communities and townships, however, do not have access to clean, running water in their homes in order to regularly wash their hands.

In an effort to reduce the risk of cross infection in the Mother City’s most vulnerable communities, Dow Southern Africa partnered with Plastics|SA and the Justice Coalition last week to distribute 20 liter PacXpert plastics pouches –  lightweight, refillable bags, containing soapy water – to COVID-19 action community groups operating in Khayelitsha, Mitchells Plain, Woodstock and Wynberg. The City of Cape Town’s Solid Waste Department also received 80 of these bags for use on their trucks by waste collectors.

“The COVID-19 pandemic presents us with new challenges every day. Recognising the health dangers that are posed when many hands touch and use the same tap to access running water, we wanted to offer a practical solution that would help flatten the curve and prevent people from leaving the safe confines of their homes during the period of national lockdown,” says Cicelia van Rooi, Managing Director of Dow Southern Africa.

The PacXpert pouch is an award-winning, flexible and sustainable alternative to using conventional containers. It lightweight, durable, refillable and easy to use thanks to its distinctive cube shape that makes it very stable. The pouch stands equally well upright, on its side or cab be hanged.  It can also be re-used many times over and is fully recyclable.

According to John Kieser, Plastics|SA’s Sustainability Manager, they have been distributing these bags under the banner of Dow’s Project Butterfly – a social initiative that was launched in 2017 with the primary focus of creating jobs and reducing plastic pollution in South Africa through education, clean-ups and innovation-focused initiatives.

“We were able to distribute these bags quickly and effectively to various smaller community groups operating around the city and have dedicated teams in place to replenish the bags with soap and water twice a day,” Kieser said.

“Dow supplies the world with materials needed for many life-critical applications, such as disinfectants, sanitizers, cleansers, personal protection equipment for healthcare professionals, memory foams for hospital beds, and more. I am very proud that we are able to make a small, but very important contribution to fighting the pandemic by putting our assets to work to help protect human health, protect our environment, and help reduce the impact of the pandemic on the world we all share,” Van Rooi concludes.

Plastics Industry shows its support for waste pickers during Lockdown

Johannesburg, April 20, 2020.  South Africa has close to 60 000 waste pickers who play a substantial role in the country’s waste management industry. As part of the country’s informal waste sector, they help recover recyclables from household waste streams, as well as waste materials sent to landfill sites. With the country in a national lockdown due to the COVID-19 outbreak, these waste reclaimers suddenly and unexpectedly found themselves unable to put food on the table due to the fact that economic activity was limited to essential food and health products or services only.

 

“It became clear that South Africa is not only facing a global health pandemic, but increasingly also the possibility of a humanitarian crisis as these waste reclaimers are no longer allowed to work and earn a living,” says Anton Hanekom, Executive Director of Plastics|SA – the umbrella body representing all sectors of the South African plastics industry – including polymer producers and importers, converters, machine suppliers, fabricators and recyclers.

 

Despite the fact that many role-players in the plastics industry are suffering financial losses during this time as they had to either close down or greatly reduce their operations, Plastics|SA, the plastics PROs, the other packaging PROs and Packaging SA rallied together to donate funds when the request was made by Packaging SA. Working in close partnership with the Department of Environment, Forestry and Fisheries (DEFF) and in support of the members of the two associations representing the waste pickers/reclaimers, i.e. the South African Waste Pickers Association (SAWPA), African Reclaimers Organisation (ARO), a total amount of R785, 000.00 was collected within a matter of days. These funds will now be used to purchase electronic food vouchers that will be sent to the collectors who are on the DEFF database via cellphones and can be redeemed at major supermarket retailers.

 

“We felt deeply affected by the dire and uncertain circumstances these waste reclaimers, who play an important role in the waste management industry, were facing. Because they are not incorporated into the country’s formal waste economy, they tend to lead a hand-to-mouth existence, which means that their income and thus food supply is directly linked to the amount of recyclables they collect on a daily basis, which completely ceased during the period of lockdown ,” says Mandy Naudé of Polyco.

 

Cheri Scholtz of PETCO highlighted the important role reclaimers play in the recovery of PET bottles and other recyclables in South Africa for reprocessing, and in the process, a lifeline for themselves as reclaimers are paid on a daily basis for the product they deliver to buy-back centres and reprocessors. “In the current situation, recycling is not an essential service and therefore the loss of access to collection has created great hardship for reclaimers,” she stressed.

“Waste pickers make valuable resources available for reintroduction into the economy, while saving landfill airspace. In some instances, these informal waste reclaimers are the only people who recover recyclables in municipalities that do not have a two-bin collection system for separation at source. We have a responsibility to support them in these trying times, they are in desperate need to feed their families,” says Adri Spangenberg, CEO of the Polystyrene Association of SA and the Southern African Vinyls Association (SAVA).

The South African Plastics Recycling Organisation (SAPRO) said that the collection of plastics for recycling is a lifeline for many informal waste reclaimers. “At a time when this very livelihood is threatened (because of the lockdown situation) we consider it the least we can do to ensure our collectors and their families have food on the table,” said Johann Conradie, Chairman of SAPRO.

“Aside from supporting sustainable livelihoods, these informal waste reclaimers provide plastic feedstock to our buyback centres and recycling plants. They form the backbone of our recycling economy in South Africa and enable us to achieve the fantastic recycling rates we do!” he added.

“The current COVID-19 crisis has left no sector or industry untouched. Despite facing their own financial and operational hardships, I commend our PROs, every member and individual company who stepped up to the plate without a moment’s hesitation. Irrespective of the amount, every donation made to the waste pickers’ fund or who answered our call to donate to the Solidarity Fund, has helped to make a difference in somebody’s life. Helping one person might not have changed the whole world, but it changed the world for one person.

 

From the plastics industry’s side, we will do our best to offer them our on-going support during this difficult time in recognition of the important work they do. There is no certainty when the lockdown will end, and we therefore challenge everybody involved in the waste management sector to rally with us and to continue making tax deductible financial contributions to lighten the burden of the waste pickers. Once the lockdown restrictions ease, we will do everything in our power to get the recycling industry operating at full capacity as quickly as possible,” Anton concludes.

A brief history of the major plastic polymers

Plastics are such a vital part of modern life; we have become unaware of how much we rely on them every day. However, many plastic polymers have only been around for a few decades. Life before these innovative materials was very different. They have made modern living simpler and safer, thanks to their durability, affordability and versatility.

The first major discovery of a plastic polymer was made in 1862. Since then, new polymers have been developed and discovered continuously – rapidly increasing from the end of the 1920s. Here is a brief history of each of the major plastic polymers and how they have changed the way in which we live.

Parkesine 

First developed in 1862, Parkesine was the first man-made plastic. It’s inventor, Alexander Parkes, revealed the plant-based polymer at the Great International Exhibition in London. Parkesine is a transparent and mouldable plastic that retains its shape when cooled. It was first marketed as a cheaper alternative to rubber, allowing users to mould and create whatever they needed.

Celluloid

In 1865, John Wesley Hyatt developed a new way to make billiard balls from cellulose nitrate. This material was far cheaper than the traditional ivory balls. Soon afterward, companies began manufacturing numerous products from celluloid, such as bowls and combs, as a cheaper alternative to bone, tortoiseshell and other expensive materials.

Rayon

This modified celluloid polymer was developed in Paris by Louis Marie Hilaire Bernigaut in 1891. He was looking for a way to manufacture a substitute for silk – a polymer that could be extruded into thin, shiny strands and woven together to form a silky fabric. Bernigaut called the polymer rayon because it had a shiny appearance that reflected rays of light.

Bakelite

In 1907, a completely synthetic plastic was developed that retained its shape and form, even under stress and heat. Bakelite became extremely popular in the 1920s when numerous products were manufactured from the polymer. Plastic jewellery, telephones and clocks became popular as people embraced the unique appearance of Bakelite.

Cellophane

Cellophane was invented by a Swiss chemist in 1912 who was looking to create a waterproof tablecloth. Later, in 1927, cellophane was used to wrap sweets and candies which really punted its use in the food industry to new heights. This moisture-resistant polymer kept the sweets fresh for longer as water vapour in the air could not affect the sugary treats within the wrapping.

Vinyl

Polyvinyl chloride (PVC or vinyl) was developed in the 1920s to replace natural rubber. It quickly became known as one of the most versatile plastics. It is commonly used to make medical tubing, plumbing pipes and construction products. PVC can be both rigid and flexible, which was why it became so popular in a number of industries.

Polyethylene

This widely-used plastic was first developed in the 1930s in the United Kingdom. Polyethylene is the most popular polymer to date and is the mainstay of modern packaging. It is used to create polyethylene terephthalate (PET) beverage bottles, high-density polyethylene (PE-HD) containers and low-density (PE-LD) shopping bags. 

Polyvinylidene Chloride

Not to be confused with PVC, this polymer was discovered by accident in 1933. It was initially used to protect military and naval equipment from the effects of saltwater at sea due to its ability to cling to other materials and form a protective barrier. Polyvinylidene chloride is also used as a protective film for food packaging and is marketed as “Saran wrap”.

Nylon

This polymer changed the entire textiles and clothing industry. Nylon was developed in 1939, after which DuPont unveiled women’s stockings made from nylon at the World Fair in New York. Nylon quickly became an affordable man-made alternative to silk and cotton, finding particular use in military clothing during World War II.

Polyester

Polyester was first discovered in the 1940s, but only gained significant popularity in the 1950s. DuPont marketed a new fabric under the name “Dacron”, which was simply woven polyester strands. This became the first washable synthetic fabric and the textile industry has never been the same.

Polypropylene

Polypropylene (PP) came about in the 1950s but it began with a legal battle over its true inventors. It is a highly-versatile plastic that is used to manufacture a variety of moulded products, such as dairy tubs for butter and ice cream, plastic furniture, buckets, car bumpers, fibres and woven cloth. It can be used in almost all plastic applications.

Polystyrene foam

Also called expanded polystyrene, this polymer was developed in 1954 by Dow Chemicals. The company introduced the polymer under the brand name “Styrofoam” and was marketed as a lightweight protective packaging product. It is used to make packaging peanuts, takeaway food containers and coffee cups.

These polymers have become so widely used that we don’t even notice the importance of plastics in our daily lives. The innovations that led to the development of some of these products are often underappreciated. Plastics have a vital role to play in modern living, the economy and even the environment.

Four cool facts about plastics recycling

The main benefit of most plastics is that they are recyclable. We can keep existing materials in circulation and reuse most plastic products over and over again. Plastics are a valuable material – they are cheap to manufacture and are used in every aspect of daily life. They also require little energy to produce and recycle, making these durable products carbon-efficient.

The South African recycling industry is one of the best in the world. In 2018 alone, the sector processed 352 000 tonnes of plastic waste back into raw material. That’s 15% more than in Europe. The industry provides income opportunities for around 60 000 South Africans, contributing just under R2.3-billion to the economy. Here are four more facts about plastics recycling that you may not know:

1. Used packaging isn’t always recycled into new packaging

Recyclers clean, shred and extrude plastic waste into small pellets that are then sold back to plastics manufacturers as raw material. While certain polymers are separated from the waste stream and processed together, it does not necessarily mean that they will be turned into similar products – PET bottles don’t always get recycled back into PET bottles. Some of these plastics are turned into toys, garden furniture, clothing, duvet inners, floor mats and even car bumpers.

2. Bottles can be recycled into clothing

Building on from the previous point, plastic bottles are often turned into woven fabrics for the clothing and textile industry. The PET plastic waste is cleaned, shredded, melted and stretched into thin threads of plastic. These threads are then woven together, just like cotton, to produce rolls of material that can be turned into shopping bags, t-shirts and even fleece jackets.

3. Plastics recyclers want your lids

Many people discard their lids in the general waste bin. Bottle caps, butter tub lids and other removable lids are just as valuable as the actual containers themselves. In fact, recyclers want these plastic products because they are usually clean, label-free and easy to process. Consumers should always put the lids back on the containers and discard them in a recycling bin.

4. Plastic shopping bags can be recycled

There is a myth that plastic shopping bags cannot be recycled. While this may have been true a decade ago, new technologies and recycling processes have allowed recyclers to process thin grocery bags. The same goes for cling films, zip-lock bags, product wraps and other flexible packaging materials. In fact, shopping bags are 100% recyclable, meaning that there is no wasted material in the recycling process.

These four facts about recycling show why it is such an important industry in modern life and how it supports tens of thousands of South Africans. Every citizen has a responsibility to dispose of their plastic waste in a responsible manner by placing it in a recycling bin. Companies and plastics manufacturers are already doing everything they can to ensure that these products are used properly and are recycled effectively.

Surprising facts about plastics and the environment

It’s undeniable that plastics play a huge part in our daily lives, from the nylon seatbelts we wear in cars to the plastic bags that keep our food fresh. Plastics keep us safe, healthy and benefit our lives in too many ways to count. But did you know that they can also benefit the environment? 

Plastics get a lot of criticism when it comes to litter and pollution, but they can actually help to save the planet – especially when used and disposed of properly and responsibly. They can play a large role in sustainability and helping us to lower our environmental impact. Here are some surprising facts about plastics and the environment.

1. Plastic packaging reduces all types of waste

Plastics are widely used as a packaging material. They are strong, lightweight and durable. They protect our products from damage and our food from spoiling too quickly. In this regard, plastic packaging actually reduces waste by protecting our goods and foods. They allow us to use our products and eat our food; without packaging, these items would simply be discarded before they could be sold.

Numerous life cycle studies have found that plastic packaging actually delivers more food with significantly less waste. They also use less energy and have a lower global warming potential than most of the plastic alternatives currently available. By extending the shelf life of products and foods, plastic packaging can prevent a lot more waste.

2. Plastics lower our environmental impact

Plastics can actually help humans to minimise their environmental impact by reducing waste, energy use and carbon emissions. A recent study found that the environmental cost of using plastics in consumer products is nearly four times less than the cost of using other materials. The study suggests that replacing plastics with alternative materials will be more expensive because plastics allow us to do more with less material.

3. Plastics help to improve fuel efficiency and reduce carbon emissions

Some cars on the road today are made up of about 50% plastic components by volume, from interior panels and dashboards to bumpers and engine housings. Plastic is a lightweight material and as we know, lighter cars use less fuel. Plastics help us to minimise our fuel consumption which, in turn, reduces carbon emissions.

A 10% reduction in vehicle weight can improve fuel efficiency by up to 8% over the lifespan of the car. Certain plastic components, such as underbody shields, help to improve the aerodynamics of our cars. This further improves fuel efficiency and lowers greenhouse gas emissions from modern vehicles. 

4. Plastics in the construction sector help to save energy

Plastic building and insulation products help us to save energy by keeping our homes at a comfortable temperature. This minimises the need for air conditioning or heating, both of which consume large amounts of electricity. These building products, such as polystyrene pipe insulation and plastic-based sealants, allow homeowners to reduce their overall energy consumption – saving money and the environment at the same time.

5. Plastic recycling is saving the environment and creating a sustainable economy

South Africa has one of the best recycling industries in the world – last year we recycled 15% more plastic waste than Europe. Recycling infrastructure and initiatives are growing year-on-year, allowing us to reuse more plastic materials than ever and keep them in circulation. 

This benefits the environment as it keeps plastic waste out of landfills. These materials can sometimes be washed into rivers during rainstorms or blown away in the wind. By recycling plastics, we are keeping existing materials in circulation and out of nature. The entire recycling industry also supports around 60 000 South Africans and generated just under R2.3-billion for the national economy last year alone.

These facts all show how plastics can be used to benefit the environment. If used properly and responsibly, plastic products and packaging can lower our environmental impact by reducing waste, carbon emissions and energy usage. They allow us to do more with less material. Plastics should always be disposed of in a recycling bin, never dumped or littered.

Major global vehicle manufacturer recycles over 1-billion plastic bottles

Plastics are such important materials for daily life. We can find them anywhere we look; they have multiple uses in all aspects of society, from the home and work to medicine and construction. Plastics can even be found in the automotive industry. Did you know that Ford uses recycled plastics on its vehicles?

 

The global vehicle manufacturer recycles over 1-billion plastic bottles every year and turns them into vehicle parts, such as underbody shields and wheel arch liners. “The underbody shield is a large part and, for a part that big, if we use solid plastic it would likely weigh three times as much,” says Ford design engineer Thomas Sweder.

 

Ford first started using recycled plastics in the 1990s, however, over the last two decades, the need and uses for plastic vehicle components have grown exponentially. This means that the amount of raw plastic required by vehicle manufacturers has risen dramatically. By using recycled plastics, Ford is helping to establish a circular economy and adding to the environmental and economic benefits of the recycling industry.

 

How plastic bottles are turned into vehicle parts

 

It takes around 300 plastic bottles to manufacture all the plastic components for a single vehicle. Plastic bottles are collected from recycling bins and processed at local recycling facilities. The recyclate is then sold to suppliers who extrude it and turn it into a fibre. 

 

These fibres are woven together with other materials in a textile process to make a sheet of lightweight plastic material, which is then used to make the automotive parts. “We look for the best materials to work with to make our parts and, in this case, we are also creating many environmental benefits,” explains Sweder. 

 

Plastics help to improve vehicle performance

 

Due to its lightweight characteristics and durability, recycled plastic is the ideal material for non-cosmetic components such as underbody shields and wheel arch liners. These parts help to improve the aerodynamic efficiency and the fuel economy of the vehicles. 

 

“Ford is among the leaders when it comes to using materials such as this, and we do it because it makes sense, technically and economically, as much as it makes sense for the environment. This material is very well suited for the parts we’re making, and is extremely functional,” states Sweder. 

 

In South Africa, Ford has established recycling programmes at its dealerships and manufacturing plants. The company also encourages all of its suppliers to recycle their plastic waste. This helps to minimise the volume of plastics that end up in landfills and also support the local recycling industry.

PP plastic packaging successes

Polypropylene (PP) is the fourth most-widely recycled polymer in South Africa. This plastic is durable, versatile and readily available around the world – in fact, just under 62 000 tonnes of PP were recycled last year alone in South Africa. PP is one of the most widely used polymers in the world and 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 – last year we recycled 15% more plastic than Europe. Of this volume, PP packaging was the fourth-highest polymer in terms of volume of recyclate. Most of the PP plastic waste comes in the form of dairy containers, sweet wrappers, plastic furniture, houseware and buckets. These materials are recycled into refuse bins, shopping baskets, coathangers, flower pots and storage containers.

PP recycling is a successful industry

PP waste is a common material processed at South African recyclers because it is readily available and one of the most widely-used plastics. PP is popular in consumer applications, as well as industrial uses, making discarded PP waste an abundant material. It can come in the form of plastic products or a fibre twine.

The end-markets for containers and other semi-flexible packaging polymers, such as PP, are growing steadily year-on-year. The biggest end-market for recycled PP is domestic houseware, by far. This is followed by the furniture sector, then the electric industry. Some of the PP recyclate is sold to the rigid packaging and export markets.

PP plastic has a number of beneficial properties

PP fibre is easy to extrude and also has the right balance of toughness and flexibility to make a variety of woven products. The hollow nature of the fibre gives it excellent water (and sweat) absorption properties in clothing and other fabrics. Moulded PP products hold colour well, don’t absorb water and are ideal for robust applications, such as moulded car bumpers, luggage and storage boxes. 

PP has excellent chemical resistance. It is non-toxic and can be used in food-contact applications –  such as ice cream and yoghurt tubs. However, one of the main advantages of PP is that it is incredibly versatile and robust. This is why the polymer is such a popular choice and has so many applications in modern life. These properties make PP one of the most widely recycled plastics in South Africa.

Plastic packaging type 5 – PP

Modern life as we know it would not be possible without plastics and plastic packaging. They keep our goods protected, our food fresh and are vital for the functioning of daily life, whether we are aware of it or not. Plastics have many advantages, including cost-effective production and being easy to recycle and reuse. 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 globe by recyclers, waste management companies and plastics manufacturers. 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 fifth polymer used for plastic packaging is polypropylene (PP).

What is PP?

PP is a hardy, flexible and versatile polymer that is used to manufacture a variety of moulded products, such as dairy tubs for butter and ice cream, plastic furniture, buckets, car bumpers, fibres and woven cloth. PP is the fourth-most commonly recycled polymer in South Africa due to its various applications in daily life. Just under 62 000 tonnes of PP were recycled in South African facilities during the 2018 financial year.

Polypropylene is a member of a group of plastics known as polyolefins. Structurally, it is similar to polyethylene, the difference being that every other carbon in the backbone chain has a methyl group attached to it. Its durability and flexibility make it the perfect polymer for packaging and woven products. Recycling figures for PP over the past five years have shown steady growth, year-on-year. This can be attributed to the fact that more applications are being developed for PP and that a well-established collection network exists. 

Benefits of PP packaging

PP has numerous unique characteristics that make it a valuable packaging material. It is one of the most widely-used plastics in everyday life. PP holds colour well, doesn’t absorb water and is ideal for such robust applications as moulded luggage and storage boxes, woven bags and carpet backings, houseware and tools. Its flexibility also allows plastics manufacturers to make hinged products from PP, such as clip-on lids for plastic containers.

PP is a non-toxic and non-reactive plastic, so it can be used in the food and beverage industry to store goods for consumption. The hollow nature of the fibre gives it excellent water (and sweat) absorption properties in clothing and other woven fabrics. These characteristics and benefits make PP a highly valuable plastic packaging material and one of the most recycled polymers in South Africa.
