Making biocomposite materials entirely from renewable sources is great. Using waste material in the process is fantastic.
Last week Finnish UPM introduced a new fibre based biocomposite material, all made from forestry and renewable resources and even including using waste from existing pulp production. The material is called EcoAce and meets the desired sustainability requirements and can be widely used, including uses in food contact, personal care and consumer goods, made by injection moulding or extrusion. This is great and will save tonnes of GHG and I really like concept of finding practical use of stuff that would otherwise be waste! Splendid!
StoraEnso is at present busy with a trial of lids made from DuraSense, another biocomposite, together with Finnish dairy Valio. The lids are reusable and will be used on dairy product cups to test the wood-based biocomposite in food packaging. Valio sees it as a step not only towards a more sustainable packaging solution but also to less food-waste. With re-sealable packaging the content is protected, and an opened product lasts longer. Brilliant!
Power from the forest! Swedish Ligna Energy came up with another use for wood from the forest. They have developed a fibre based battery for storing of energy made from forestry waste material. Ligna Energy plan to convert ordinary paper machines to manufacture batteries based on organic electronic polymers and biopolymers from the forest. It wood be nice if this could make a difference for storing energy!
Food waste is a major challenge involving the entire value chain. The main culprit is however and without doubt found at consumer level.
This is a complex problem but part of the solution lies in using better and more suitable packaging.
We simply can’t afford the current level of food wasted. Exactly how much is wasted is impossible to say, but a global estimate is more than 1 billion tons of food that is somehow lost or wasted on a yearly basis. That is about one staggering third of the global food production! Better adapted packaging is part of the solution.
The problem This loss and wastage occur on all steps in the food supply chain but if we stay in the developed world a whole lot of food is wasted in the end of the road from the famous farm to the fork. The main culprit seems to be found at the final consumption stage, in our homes. But also, the other steps along the chain are involved in this.
A very recent report from Swedish Naturvårdsverket is mapping out the current Food Waste situation in the country. And it is not pretty. In 2018 about 1.3 million tons of food waste was generated in Sweden. This is an average of 133 kilos of food waste per person. As the graph clearly illustrates the main problem lies in the hands of the end-consumers in the households.
The problem isn’t easily pin pointed and solved as it involves all engaged in the consumption, production and distribution chain. But packaging is part of the problem and therefore also part of the solution.
The packaging link This is a waste we can’t afford when we are going from 7 billion people to become 10 billion of us, not in Sweden but on the planet, in 2050. If we instead of increasing food production and cultivate vast new areas could save a third of what we today produce, we would in theory solve the problem to feed the growing world population.
The massive waste of food in the households has many reasons. Too little shopping planning and lack of pantry and fridge management to start with and perhaps food is too cheap and available. But as much as 20-25% of consumer food waste could be related to packaging.
The packaging is a part of the problem when ineffective packaging is used.
This could be about size, too big or a multi-pack, simply too much product and more than you can or want to consume.
It could be the lack of possibilities to re-seal the opened packaging and the content gets exposed and destroyed.
It could be packaging that can’t be shut tight enough and oxygen, light or something spoils the product.
Not clear enough instructions about storage, with the result that a product is kept too warm too cold, is part of the story.
Packaging that is hard to empty or confusion around the date labelling of a product.
Or it could be too ambitious light weighting that can lead to packaging that simply isn’t good enough to withstand a bumpy ride to the destination. To mention a few. Much of the above comes to structural design of packaging but a lot of food is wasted because of the confusion about “best before” and” use by” date labels. One day we will have dynamic best before dates with built in sensors showing the actual best before date rather than a fixed one. But we are not quite there yet.
The solution Apart from consumers improving their fridge management and doing more organized shopping the packaging industry can offer better packaging solutions. And food producers can use it…!
So, what is more effective packaging then? What I mean is packaging that is
Re-sealable. That is a screw cap, a zip-lock or something that enables the consumer to save product for later.
Easy emptying. Think of how to make it easier to empty the pack. It can be instructions on how to or a packaging feature like a collapsible container.
Modified or Controlled Atmosphere (MAP/CAP) these are technologies used to keep fresh food fresh for longer and adds real value by extending shelf-life.
Barrier materials. Use packaging with good enough barriers to oxygen, light or whatever is breaking down the content. The result is again extended shelf-life and less food waste.
Portion packages. This is a low hanging but effective fruit. By using smaller portion packs, the small household gets a better control of usage.
Smart packaging solutions of various kinds are helpful. Smart labels indicating time or temperature, ripeness for fruit, freshness for meat, fish, etc.
Technology is developing enabling new and better packaging solutions. Sensors are coming down in price and new creative concepts are brought forward by entrepreneurs. But it hasn’t all have to be hi-tech, a cucumber has a “best before” life of 3 days and by wrapping it in plastic it increases by almost 5 times, to 14 days. Portion packs may require more packaging material but will probably save food from being wasted.
And the greenhouse gas emissions or GHGE related to food packaging is typically small, typically around 5%, relative to the emissions associated with producing and processing the food itself.
The craft brewing scene is booming also in Sweden with a big number of small brewers and glass bottles are the dominating pack type. Glass bottles represents tradition and premium, two of the impressions that you as a craft brewer work really hard to convey to your consumers.
When you are selling a product at a price three times above your industrial brewing competitors, you have to work hard on your image. But something is happening…
What is it with craft beer and cans? I have noticed an increased interest in beverage cans from the local craft brewers, or microbeweries, here in Sweden. One after the other launch new products in beer cans, not in glass bottles. Glass bottles used to be the standard for this premium beer segment.
The craft brewing scene is booming also in Sweden with a big number of small brewers and glass bottles are the dominating pack type. Glass bottles represents tradition and premium, two of the impressions that you as a craft brewer work really hard to convey to your consumers. When you are selling a product at a price three times above your industrial brewing competitors, you have to work hard on your image. But something is happening…
The power of glass The beverage can is in many consumer’s eyes a packaging used for mass production that does not necessary contain very sophisticated brews. The craft brewers have mostly been true to glass bottles for their precious drops, and that for a few sound reasons.
A craft brewer with self-respect have a large number of creative varieties of beer available and need flexibility in production. To use only one container and vary the label is efficient in a low volume production of several product varieties.
It is also cost effective as you can get away with rather basic equipment when filling bottles on a small scale. And it is often also simply impossible for a small brewer to purchase the amounts of decorated cans needed to reach the lowest order level.
Last but not least, the positioning of the product. Glass stands for quality, premium and tradition. These are images you very much want to reflect on your craft brew.
Incredible growth Most of the above is still valid but the trend is clearly towards using more cans for the most premium products and for very small product batches. The numbers speak for themselves, in 2019 the volume craft beer in cans increased by 2.5 times, for the second year in a row! An increase from 8% of the craft beer volume to 17% in three years. In 2017, 12 brewers made 35 beer products available in cans. In 2019 70 brewers offered more than 400 products in cans. That’s an improvement!
Why is this? The trend is clear and seems unstoppable. The movement is founded on a few obvious facts and some a bit more hazy.
* Some of the craft brewers have simply expanded their markets and volumes and are ready to invest in cans and a can filling line. * Others have managed to get one single and specific product on a national distribution and can take the leap with that one product. * Some who not yet have those volumes use blank cans and attach a unique label to maintain the flexibility.
Then it helps that the suppliers of cans have spotted the opportunity in craft beer and are lowering the bar for the smallest order. Finally, but not least, consumers appreciate the product.
Environment and quality All brewers I have heard comment on this argue the environmental benefits and the improved quality of the product. A sealed can is an airtight space and it is completely dark inside which maintains the quality. A can is easily recycled in this country with an efficient deposit scheme in place. As a matter of fact, 85% of the distributed cans are returned and recycled.
Marketing by packaging They just do it! And they do it within the very narrow space that is left due to the current and very strict regulations around all alcohol promotion. They build their brand using the means that are available, except from the product itself what is left is basically, the website, the shop and the bar. At the point of sales there is nothing else you can use than the packaging itself. This is a clean case of marketing by packaging. The pack type, size, design and decoration are key to positioning and sales of a beer product in this market.
They utilize the packaging very well with brilliant graphic design, creative fonts and inspirational product names. And of course, a great product with a high and stable quality is very helpful when you want to convince consumers.
An inspiring industry This is a small scale industry with very limited resources that is constrained by square and rigid laws. They have still managed to turn the opinion and make something considered as a very basic packaging into a premium container. And successfully claiming a price three times the “normal”. This is quite an achievement and well worth to celebrate. Why not with an unfiltered, hoppy and hazy beer? From a can, plenty to choose from…
Yes, what do we want instead? We can’t always replace plastic with a renewable material. Then what about recycled plastic, more sustainable plastic that is efficiently recovered and that comes from an organised collection system? Does that sound a bit better?
Coca-Cola is in the news with their new line of bottles entirely made from recycled PET. Fantastic! Coca-Cola Sweden is during 2020 switching to only use PET bottles with 100% recycled material for their leading brands, Coca-Cola, Fanta, Sprite and Bonaqua, 40 SKUs.
This is not a small thing as using recycled material in food contact is a complex mission surrounded by of rules and regulations. The Swedish deposit system really helps here as it makes the recycling stream of PET bottles relatively pure. Beverage bottles, and cans, are here collected and recycled separately and can in theory be turned back into new cans and bottles. Today around 85% of the distributed bottles are returned and recycled. Normally recycled PET tends to be cloudy due to unintended mixes and potentially tainted by other random plastic in the recycle process. This is avoided in a controlled stream like this.
In a recent report from McKinsey, “The drive toward sustainability in packaging—beyond the quick wins”, this is discussed, among other things. The report concludes that to successfully address the recyclability and waste challenges more collaboration is needed along the value chain. To manage increased recycling new infrastructure needs to be built and more closed system must be employed.
A closed and dedicated deposit system clearly makes recycling more efficient as it is separate and, closed. The Swedish deposit system is managed by Returpack, an organisation owned jointly by retailers and fillers together. When the deposit system was created also packaging converters were involved which makes it a good example of an efficient recycling structure.
Another brand owner who is blazing new trails in this field is Nestlé. The company is seriously investing in the development of new packaging concepts in their effort to have 100% of its packaging recyclable or reusable by 2025. The newly inaugurated Nestlé Institute of Packaging Sciences is unique and aims to support the process. The Institute is going to do its bit of development of functional and environmentally friendly packaging solutions and to address plastic packaging waste.
Nestlé is now investing a staggering €2 billion to explore the possibilities to widen the market for food-grade recycled plastics. The Institute will be involved but the main investment will be in driving the market for food-grade recycled plastics by boosting demand and by being ready to pay a premium. They are now demanding 2 million tons over a period of time and are willing to pay for it, to create a market. Brilliant!
Plastic is at present needed, especially in the food industry to minimise food waste, and it is possible to create a circular economy also for plastics. To get there a system for collecting and recycling plastic must be in place. But there needs to be a corresponding demand as well. Today it is more expensive to use recycled materials than virgin. But with a higher demand and larger volumes the price should go down and thereby generate more demand. Hopefully a process that creates a virtuous cycle spinning us towards a circular and healthy economy.
These are great examples of steps in the right direction to increase demand for recycled plastic materials. This will also drive the development of efficient systems for processing. But, in the end, the consumers are going to do a big part of the job. We must not forget to inform and motivate to sort and return the empty packaging through this efficient system.
E-commerce will continue to grow, and that at the expense of traditional retailing. Online shopping will soon be the norm for shopping. The supply chain needs to adjust to this.
One man’s convenience is another man’s stress One of the consequences of us shopping from home, or on-the-go using the phone, is a stressed logistics system. The result is visible, congested traffic and overloaded bottle necks. The logistic system supporting online shopping can be divided in two steps. The first leg is from producer to a Customer Fulfillment Centre or CFC. The second is from the CFC to consumer. This is a very different supply chain from the traditional and we have all noticed the growing number of lorries on the roads. New innovative delivery methods are invented and tried out. Robots, drones and electrical vehicles of all kinds, self-driving and not. These solutions are mainly focused on the last mile delivery, that is from the customer fulfilment centre (CFC) to the consumer. This “last mile” transport can be organised in various ways, it can be home deliveries or to a pack-station at offices, supermarkets or in train stations.
Remarkable last mile solutions
Drones Amazon introduced the concept of drone deliveries in 2016 and shared a few months ago a project update. They are still developing the concept and now showed us an increasingly sophisticated flying vehicle capable to deliver up to 90% of the packages they are delivering today. And safely too. Wings has a similar solution but with a different spin. They offer the same service, drone deliveries, but instead they link consumers to a range of local stores. An order is placed, and the drone picks up goods from the specified shop and delivers, all the way home. On trial in Australia, Finland and in the US.
Robots Some drones are instead found moving around on the ground. In the UK, Tesco has started to deliver groceries using robots. A pilot test is located to Milton Keynes where Tesco is working with Estonian based robotics company Starship Technologies. A low 6-wheeled cart carries parcels, meals and groceries delivering to homes within a 3 km radius. In the US Kiwibot is doing very much the same, home deliveries using robots, but in this case the 4-wheeled carts are bringing food from local restaurants. Also this is a concept in the building but it is inspiring to see all the creativity coming out to meet the demand for fast home deliveries.
The first leg of the supply chain The above are solutions for shorter distances, the second leg of the supply chain. To get the goods from the producer to the CFCs lorries, train and boats are used, creating traffic overflow. That is until now. Until we heard of Magway.
British Magway has come up with the idea of building a network of pipes around the country. This planned grid of tubes, with a diameter of 90 cm, is supposed to carry goods, beneath and above ground. Instead of using trucks on the road, cargo will be sent around in pods in these tubes fitted with rails and powered by magnetism. An electric current will run through a track in the pipe, creating a magnetic wave that will drive the packed pods at speeds of 80 km/h.
Magway is an example of sustainable new thinking for a new era where consumers want their goods and that immediately. The normal distribution chain with goods-in-cases-and-on-pallets will with increasing online shopping soon not be the norm anymore. Online shopping means that products are sent on their own or together with random other products. New methods are needed, and Magway has come up with a radical e-commerce delivery system that will reduce traffic on the roads and ease traffic congestion. The system promises reliable and predictable deliveries to CFCs and to a lower cost.
The first route planned is an 80 km route from northwest London to Milton Keynes, where large numbers of distribution centres are located. Already this year a 2 km test track will be built and tested.
This is an interesting period in time when online shopping is growing very fast and shoppers are expecting immediate deliveries. New solutions are really needed to gear up the supply chain for the new needs with lots of room for new thinking and developing of new concepts. All the above mentioned enterprises are going to be exciting to follow and I will absolutely keep an eye on all of them.
It’s a bit more complicated. Last year we used 264 billion paper cups according to Imarc. This translates to a number of trees, an amount of water, a quantity of energy and a number for the miles transport needed. No doubt, it’s not for free from a climate point of view. This fact has gotten quite a lot of attention during the last few years, maybe with a peak two years ago, when consumers questioned the use of single-use cups.
Another perspective on this comes from a recent, 2019, LCA study carried out by VTT or Technical Research Centre of Finland. The study shows that the paper-based coffee cup is performing quite well for carbon dioxide compared to the alternatives. The comparison was to reusable cups in different materials. But this footprint can be significantly improved by properly recycling the emptied latte cup.LINK TO MY WEBSITEAdd Button
The LCA consequences will of course depend on how the cup is made up, the amount and type of plastic used for lining and also what recycling facilities are available. We are using quite a few of these single use cups and recycling and reusing material is key to a circular economy. The average cup is not easily recycled, many plants have a challenge to separate the plastic from the paper.
This recycling situation is improving. Last year Stora Enso announced that they could successfully recycle used paper cups at their plant in both Sweden and in Belgium. They declared that used paper cups could be used as valuable raw material and be recycled into white-lined chipboard (WLC).
Recycling facilities can be expanded in many ways. This is proved by the London based charity organisation Hubbub. Together with Starbucks they launched ‘The Cup Fund’ to support paper cup recycling in the UK. Enough money has been raised, by the voluntary 5p charge added to single use coffee cups, to build recycling facilities to handle 4 million cups yearly. Every little helps.
There are other solutions available. Ball, the leading supplier of beverage cans, is testing aluminium cups as an infinitely recyclable alternative to the single use cup. They started last year and now they will be used for serving beverages at the Hard Rock Stadium in Miami during Superbowl. A stiff drink, or at least a sturdy cup.
Finally, it is important to remember that of that cup of latte only 4% of the climate impact comes from the single use cup. 96% still comes from what’s in the cup, the coffee and the milk. So, enjoy the latte and don’t forget to recycle the cup. And do finish it to minimise food waste and the climate effect of your brew.
From volatile crypto currency to a solid system adding value for the supply chain. Blockchain technology can be the key to value chain transparency and a solution to the ever-growing problem with counterfeits.
What is it?
A Blockchain is a database of records, here called blocks. What makes the database special is that these records are interlinked, or chained, using a hidden code. This is useful in a supply chain involving transport and transactions that can be recorded as blocks. Each block contains a cryptographic link to the previous block plus information on when a transaction occurred, who was involved and much more.
This may sound slightly abstract, but it makes the Blockchain concept decentralised and transparent. A key element is that the process is spread out across multiple computers with the consequence that no one has ownership of the information on the “ledger”. A non-corruptible database!
Using a Blockchain you bypass the concept of a centralised organisation by giving everyone involved a complete and unalterable copy of the register of all transactions.TO MY HOMEPAGEAdd Button
Why is it important for packaging?
Blockchain technology relates to packaging as it can be used to:
Provide consumers information regarding a product’s authenticity and origin. The identity of a product can be verified as the packaging is read and recorded to the “ledger” when handled along the transport, all the way to the destination. As the records can’t be altered retroactively, it means that all information on the ledger is by default authenticated, but without the paperwork of today.
Track and trace products along the value chain. When the value chain (packaging converters, printers, raw material producers, fillers, brand owners, retailers, etc.) join up in a Blockchain and makes the process transparent they will all share the same picture of origin and handling of products. If a batch is contaminated it can then easily be traced. Traceability is a key aspect and an opportunity, in particular for the food and pharma industries.
Ensure brand protection and serve as anti-counterfeit technology. Consumers will be able to tell a fake product simply pointing their phone at the packaging and read the QR code. Blockchain will prove to be a useful tool for building brand trust as a neutral and immutable system.
The demand for transparency and traceability is increasing, driven by counterfeits troubling the pharma industry and recent food scandals that shook the industry. Using Blockchain technology the consumer with a smartphone can simply scan a QR code on the packaging to follow the product journey, from farm to plate.
Who are using it already today?
It might not be mainstream, yet, but the technology is already in use for mundane items such as milk and coffee. In the lead we find major food suppliers like Arla who are running a pilot project in Finland using Blockchain to provide transparency for milk products. Nestlé recently started up their pilot but in a larger, or even global scale involving milk and oil. Barilla is using the technology in Italy to certify fresh basil.
Also the retailers are also into this. Carrefour is leading in Europe using the technology on a number of categories like poultry, eggs, cheese, milk, oranges, etc. On the other side of the pond Walmart is demanding Blockchain traceability for selected vegetables.
Where is this going?
This is only the beginning. Driven by the main advantages’ security, decentralisation and transparency Blockchain as a tool will gain momentum and develop fast.
The technology might seem complicated to use, but the tools are available and new entrepreneurs are coming in with easy to use solutions. With a straightforward access we can expect to see a rapid adoption rate, with a variety of applications. The packaging industry needs to be ready to handle their part of the chain of blocks. Printing and packaging are keys for success.
