In a damning expose, The Guardian has revealed that Britain͛s leading supermarkets ͚create more than 800,000 tonnes of plastic packaging waste every year͛. And, more worryingly, the paper suggests that the firms go to elaborate lengths to hide
the extent of their plastic footprint. What is clear is that their use of contractual loopholes to obfuscate the scale of plastic use prevents clear calls for change. Supermarkets were the first to be obliged to charge for plastic bags, and supermarket delivery services are often touted as a green option. However, until the products they supply are encased in less single-use plastic, they will continue to act as huge catalysts for pollution.
In the face of this, startups are setting themselves the challenge to combat the plastic epidemic. And it͛s working. A paradigm shift is coming from the world of smart refillables—smart containers can be integrated seamlessly into homes and refilled with the goods we use the most.
For the first time, the Internet of Things allows household goods to order themselves, and to be delivered in a refillable and sustainable way. Of course, Supermarkets could get in on this too, but they first need to face up to the dangers of feeding the nation͛s plastic addiction.

At Vesta Smart Packaging, we strive to significantly reduce plastic pollution and, by extension, carbon emissions used in the life cycle of one of our containers, or Vestas. It is also important that our containers be recyclable and preferable that they be made from recycled, recyclable and sustainable materials. However, choosing the materials for our refillable and reusable containers has been a more complex exercise than we had first envisioned. On first glance, bioplastics seemed to be the answers to our problems because it is a plastic derived from renewable biomass sources, such as vegetable fats, vegetable oils, corn starch, or microbiota (https://en.wikipedia.org/wiki/Bioplastic).
With a current-life of 2 years, our Vestas already show that we can reduce the number of plastic bottles containers over 2 years per product by at least 23. They can be reused after the 2 year period if the plastic container has not sustained too much damage, as we can simply steam clean them, replace their batteries and re-deploy them. However, not all of them will be re-usable and at some point, all of our Vestas will need to be recycled.
Bearing this in mind, we decided to investigate using bio-plastics as the building material for our product. The main considerations for us when choosing a material were:
Strength
Recyclability
Bio-degradability
Carbon Footprint
1. Strength
Bioplastics are generally not as strong as regular plastics. Currently, the only known way to increase their strength is to mix them with regular plastics – which we would need as it is intended to be used multiple times over a 2 year period. Though this might be better than pure plastic, it can also reduce the recyclability of the plastic and how bio-degradable it is, whilst increasing the cost. These are also important factors in choosing the correct material for our containers. There is currently research being conducted into including cellulose fibres or particles in bio-plastics to increase its strength, which will be watching closely. (see http://pubs.acs.org/doi/abs/10.1021/bm050897y)
2. Recyclability
Recyclability varies considerably with bioplastics. However, those bioplastics that are recyclable cannot be recycled with regular plastics. They require a new stream of recycling, which most recycling plants do not have. A method would have to be developed to separate bio-plastics from regular plastics to make bioplastic recycling on a large scale viable. There is also some concern that bioplastics would contaminate normal plastic recycling (https://waste-management-world.com/a/napcor-concerned-over-pla-contamination-of-pet-stream), increasing the cost and decreasing the effectiveness of plastics recycling. So in short, while many bioplastics are theoretically recyclable, very few places are equipped to process them.
3. Bio-degradability
If a bottle cannot be recycled, it is important that it is bio-degradable. Being made from bio-plastics does not automatically make a bottle recyclable or biodegradable, it just means that the plastic has come biological sources rather than fossil fuels. For example, CocaCola’s PlantBottle, which is made from bio-plastics cannot be composted and does not bio-degrade because it has the same chemical structure as a plastic made from oil (https://www.alternet.org/story/151543/compostable_or_recyclable_why_bioplastics_are_causing_an_environmental_headache). The more bio-degradable a plastic is, the weaker it tends to be. This means they might be more suited for plastic packaging of items such as fruit, or potato chips and don’t lend themselves to tough, robust packaging like that produced by Vesta Smart Packaging. The bio-degradability of many of these bioplastics is also questionable. Many require special high-temperature composting plants and won’t biodegrade in a domestic compost heap.
4. Carbon Footprint
David Grewell of Iowa State University (http://dgrewell.public.iastate.edu/research/bioplastics/cost_comparison.html) has conducted some research on the life-cycles of bio-plastics and has found that many types of bioplastic have a higher carbon footprint throughout their life than regular plastic bottles. See the video below for a more detailed analysis of this problem
Having considered these factors, we believe that bioplastic technology is not ready to be deployed for Vesta Smart Packaging….YET. However, we believe that as the technology is developed and problems are solved we will be able to move to bioplastics. The technology is constantly being researched and in time we believe that bioplastics will become stronger, more recyclable and more bio-degradable. Bioplastics are the future, but that future is not quite with us.
The world’s plastic epidemic is often portrayed as a far-flung problem – one which might cause a bit of unsightly litter on motorway sidings, but not one that could seriously affect our daily lives.
But this could be about to change.
It is a little-known fact that Britain has been selling rubbish to China, paying to pass the buck of our excess garbage, and the proof of our national unsustainability.
According to the BBC, ‘Britain has been shipping up to 500,000 tonnes of plastic for recycling in China every year, but now the trade has been stopped’.
That’s right. With China no longer willing to accept the waste – in a bid to clean up its own outlook – we as a nation will be forced to confront our throw-away, one-use culture, and the staggering quantity of rubbish that this generates.
The solution is for business, homes and manufacturers to be proactive, and to take this opportunity to adopt smart, refillable solutions for the health—not just of the planet—but of the nation.
UK faces build-up of plastic waste
UK faces build-up of plastic waste
UK does not have capacity to deal with extra plastic waste after a Chinese import ban, says industry group.
With Greenpeace reporting that the equivalent of a truck load of plastic is dumped in the sea every minute, things are looking bad for our environment.
But we mustn’t despair.
You don’t have to live in an eco-home or install solar panels to make a difference. There are hundreds of small daily things that everyone can do, which really add up to curb the plastic epidemic. Here are just a few:
Take your own bags to the shops, and don’t buy food which comes in multiple layers of packaging. Resist the urge to put individual fruits and vegetables in their own bags. Better still, write to the supermarkets and urge them to use less.
Try out a grocery delivery service. No longer the preserve of the middle-classes, these services are competitive, nationwide, and hugely sustainable. The deliveries are fixed (great for the environment), the boxes are recycled, and the produce is seasonal and organic. What could be better?
Stop buying bottled water. Just stop. Get a flask. Reuse an old bottle. Fill it up from the tap. If everyone did this, the world would be an instantly less plastic-filled place.
Reject the offer of a straw. On a night out, at the cinema, wherever. Straws are the ultimate one-use item, and even more pernicious because no one thinks about them. G&T tastes better straight from the glass anyway.
Adopt the re-usable coffee cup. The cups aren’t great for the environment, but the plastic lids are a disaster. Many companies now offer reusable coffee cups – even the high street coffee shops themselves – and many offer a discount on your coffee if you have one. Winner!
2018 has the potential to be a fantastic year, one in which we move towards sustainability and the elimination of single-use plastics.
We all know that plastic is disastrous for the environment, but it is now being revealed that plastics are making their way into our bodies.
We’re consuming plastic every day in our drinking water.
A disturbing report from Orb demonstrates that ‘tap water samples in cities on five continents is contaminated with microscopic plastic fibers. Plastic is pouring out of faucets from New York to New Delhi. Scientists say they don’t know how these fibers reach household taps, or what their health risks might be, but experts suspect plastic fibers transfer toxic chemicals when consumed by humans’.
More than 40% of our plastic containers are single-use, but ‘plastic persists in the environment for centuries’. It is perhaps no wonder that plastics are making their way into our food chain, but what is striking it the worldwide scale of the problem:
‘The contamination defies geography: The number of fibers found in a sample of tap water from the Trump Grill, at Trump Tower in Manhattan, was equal to that found in samples from Beirut. Orb also found plastic in bottled water, and in homes that use reverse-osmosis filters. 83 percent of samples worldwide tested positive for microscopic plastic fibers.’
The government’s recent targeting of single-use plastics could not be more timely, but the revelation that microscopic man-made fibres are now getting into our bodies should encourage us all to resist single-use, and find refillable reusable solutions.
Christmas should be an indulgent time of year, but as consumerism hits its November stride and December peak, our landfill use and C02 emissions increase.
Our festivities put a strain on the environment.
There are positive and low-impact steps we can all take to ensure a more eco-friendly festive season.
Gifts
Stocking fillers and one-use gifts tend to be plastic, and they tend to end up in landfill. Harvard academics have estimated that, in the US, ‘each adult spends an average 475 dollars on presents, and about half of these gifts are unwanted … A 2015 survey in Australia showed that 78.5% of people receive a gift they don’t want over the holiday season, and 13.7% of these people will throw away these unwanted gifts, rather than returning them to the store’.
Think twice about buying something made of plastic that will be disposed of by January. If it will be funny for less than a day or two, save your money and help the environment.
Return or re-gift unwanted items, and remember to include gift receipts in your Christmas parcels.
Remember to take your own carrier bags to the shops.
Have your online shopping delivered without bags where possible.
Re-use packaging when you wrap and send your own gifts.
Cards
According to the BBC, 1 billion Christmas cards end up in landfill, where they can take up to 30 years to decompose. If all these cards were recycled rather than thrown away, it would help save the equivalent of around 248,000 trees.
As well as recycling the cards you receive, try and buy cards made from recycled materials.
Try and hand deliver to friends and family who live close by and further reduce your Christmas carbon footprint .
Trees
‘Britons decorate and throw away over 6 million real Christmas trees during the festive season which produces an extra 9,000 tonnes of waste’ (BBC).
Avoid plastic trees. These are often made from unrecyclable materials, and are usually shipped from Asia, increasing their carbon footprint.
Try and make use of local recycling and freecycling services to give away unwanted fake trees, or donate via your local council to a family in need.
When buying a real tree, look out for the FSC (Forest Stewardship Council) certification. The Soil Association can give advice on eco friendly Christmas tree suppliers in the UK.
Most importantly, recycle your tree! Many local councils provide services to remove and recycle real trees for free, or have drop-off points. The trees are chipped to provide mulch for gardens and parks, and make environmentally friendly animal bedding.
‘I want us to become a world leader in tackling the scourge of plastic’
As part of his budget speech on Wednesday, Chancellor Phillip Hammond formalised the UK’s commitment to reducing plastic pollution, by promising a review of tax liabilities for companies which
adopt green practices.
This follows on the 5p plastic bag charge, ‘which is credited with driving down how many are used by 85 per cent’.
Whether this translates to incentives for companies who pioneer reusables, or penalties for those who continue to promote single-use plastics, the world’s plastic epidemic is about to have a real fiscal impact on manufacturers and vendors of everything from comestibles to industrial products to homecare.

Philip Hammond references Blue Planet 2 as he confirms plans for a plastic tax
Scientists and environmental groups have tentatively welcomed plans to tackle two of the biggest environmental threats facing the world. Chancellor Philip Hammond referenced the BBC’s Blue Planet 2 as he announced that he and Environment Secretary Michael Gove would investigate how the tax system and charges on single-use plastic items could be used to reduce waste. “I want us to become a world leader in tackling the scourge of plastic,” said Mr Hammond.
Plastic pollution is suddenly in the public eye, with everyone from legislative bodies such as the EU (though recent delays are a concern), to David Attenborough highlighting the appalling scale of the problem.
Recyclable one-use packaging – whilst welcome – looks unlikely to be enough to stem the tide of waste. The reduction in plastic content of disposables can be easily matched or exceeded by an extended period of reuse, and by adopting smart-packaging built to be re-used.
Companies and consumers alike need to spearhead the widespread adoption, or re-adoption, of reusable packaging. Simply using the same package twenty times would reduce plastic waste by 95%.
This is not an entirely new idea. Most people over the age of thirty remember the widespread use of milk bottles, which subsequently disappeared. There are a number of reasons for this, but what has changed since the demise of the milkman, is the widespread use of personal delivery and the availability of connected platforms that can more effectively manage the process.
The Guardian has learned that 1 million plastic bottles are bought and sold every minute around the world. This amounts to more than 1 and a half trillion bottles per year and is only due to increase unless drastic measures are taken.
Former yachtsman and global navigator, Helen MacArthur writes:
“Shifting to a real circular economy for plastics is a massive opportunity to close the loop, save billions of dollars, and decouple plastics production from fossil fuel consumption.”
Hugo Tagholm, of Surfers Against Sewerage adds:
“Current science shows that plastics cannot be usefully assimilated into the food chain. Where they are ingested they carry toxins that work their way on to our dinner plates.Whilst the production of throwaway plastics has grown dramatically over the last 20 years, the systems to contain, control, reuse and recycle them just haven’t kept pace.
We are confident that with the use of smart packaging and the changes in home-delivery culture, that the amount of plastic bottles used by the general public can be reduced significantly and that MacArthur’s and Tagholm’s goals can be met.
