Spending a working life dealing with packaging issues I have always been skeptical to the general idea of ”packaging free” or “edible packaging”. I think it doesn’t make any sense, at all. Wrapping something edible in, again, edible packaging normally creates a demand for yet more and properly protective packaging.
But I may have to reconsider and think out of my limited box.
First, I got to know about Saveggy, a company that have developed a concept of a protective and edible solution for fruit and vegetables.
They can offer a bio-based coating that does the same work normally done by using a plastic film and prolongs the shelf life of produce to minimize food waste. The plant-based coating, fully edible, is sprayed on fruit and veg to extend the shelf life and seems to do the same for a cucumber as a plastic wrap. Brilliant!
Another excellent, actually, usage of the ”packaging free” concept is the pod-like coffee system recently launched by Migros. CoffeeB is a fully compostable coffee ball without the usual aluminium pod. It’s simply coffee pressed to into a ball that fits in one of their CoffeeB machines. That is also the one downside, you have to buy yet another machine to squeeze in to your kitchen.
Well, that was two brilliant new products in an otherwise very dull segment. I wonder what comes next, and I am looking forward to being pleasantly surprised again.
You can easily say that, never before has so many EU-initiatives that concerns the packaging industry been active as right now.
Right now, we are looking at an intense mix of newly launched directives and updating of old ones, all with a direct impact on the packaging industry. Thereby also on the manufacturing industry in general and the food & beverage industry in particular.
You can speculate in why these initiatives are stacked so high at this moment, but it is right in time. Recycling, reusing and reducing packaging waste are the new normal and will not change in any other direction than, even more.
What we now see is an EU Commission pressing all buttons to quickly change the present situation and reach the rather ambitious goals. Goals that yesterday was increased to a 55% reduction of GHG by 2030. That is compared to the previous goal of 50%.
You could argue that 50-55% are within the margin of error but this demands a huge effort of the entire society of which the packaging industry is a part.
It is also this ambition that in the end, by 2050, to become a completely climate neutral continent that is the reason for the storm of initiatives initiated that involves the packaging industry. And their customers, the brand owners and fillers.
“The European Green Deal” is a major flag ship project launched last year. It contains a very ambitious set of policy initiatives regarding clean energy, toxic free environment and much more. In this bundle are two components that will have a significant impact on packaging.
Part of this initiative is “The Farm to Fork Strategy” which is much about food and beverages but contains parts that will affect packaging. You could summarise the goal to be “Sustainable food in sustainable packaging”.
The “Circular Economy Action Plan” is also a part of this huge initiative. A part where packaging is specifically named as a focus area. Key words are sustainability, reduced packaging and circularity.
These are new and you can say that about “The Single Use Plastic Directive” as well. This directive has from the introduction last year been hurried through the system and will be a reality next year. This with huge consequences for all involved when the use of plastic is limited and phased out with rules and fees.
Those were the new ones, then we have a few very well-established building blocks that are considered to need an update.
“The Packaging and Packaging Waste Directive” was introduced quite some time ago and has been updated every 10 years. Now it is time again, after only 5 years… This is an important part of the free movement of goods within the union and is much about promoting reuse and recovery.
Finally, it is time for a refreshing of “The Waste Framework Directive” which has been with us for a long time but is now due for an update. This is basically about the Extended Producer Responsibility and the Packaging Fees to finance the collection and processing of packaging waste.
This is together quite a lot and something of a perfect storm where separate forces are pulling in the same direction which promises real results. This is happening right here, right now and will have consequences within a period of 2-5 years. The result can be influenced but only now, before the train leaves the station.
It is now we have the chance to let the decision makers hear our voice in this. The Commission is welcoming input that we as an industry probably most efficiently can give them through our organisations. It is so important that we do this, a number of very important decisions are going to be made within short and it is crucial that these decisions are made on the basis of facts and science rather than on intuition and short-term gains. So, let them hear how things are, actually.
The real effects on the packaging industry from the present virus crisis is hard to comprehend. But regarding food packaging in the short to medium term we will see online grocery shopping grow, more focus on hygiene and price without losing the grip of sustainable solutions.
The long-term consequences of a pandemic like this one is hard to have a strong view on at this stage. Likely short-term results appear to be a downturn in the overall economy with double digit declines of GDP’s and increased unemployment. Some of the hardest hit industries, so far, seem to be the hotel and restaurant industry, the travel and event industries and retail.
When it comes to retailing it is not anything like a general decline, the grocery retailing is in a much better position than capital goods retailing. Right now, people obviously stay more at home for eating and socializing. Going out is rarely an option and food and beverages are bought from stores rather than restaurants. Also, pharmacies are open for business selling medicines as well as personal care products.
Where is this possibly going then?
As a result, the pandemic is speeding up trends like remote working but also online grocery shopping and possibly other retail technologies. The effects of this pandemic for the retail industry could be an increased e-commerce business as well as growing interest in cashless stores, automated replenishment and cashier free self-checkouts.
And for food packaging?
Demand for food packaging as such will be up as people will eat more at home. Now when many restaurants and food-service outlets are closed this is obvious, but as the crisis opens for new behavior patterns some will stay, also when things get a bit more normal. There might also be some stockpiling and a new normal can very well be to have more than a few days of preserved food in the larder. This also goes for personal care and healthcare products.
Grocery e-commerce has so far been developing at very different paces in Europe. The UK is still in the lead according to Forbes (2018) followed by Czech Rep. and Estonia. As a result of the virus pandemic the habit of ordering online and receiving, or picking up, your shopping is fast developing and will get a boost from the extreme situation we are now experiencing. This is a clear step in consumer acceptance and adoption of the channel. New and better packaging solutions are being developed and innovative delivery methods are created.
I don’t think that sustainability will go away because of the shifted focus. The consumer demand is too strong, and the concept of sustainable packaging solutions has gotten ingrained in product and company positioning. Demand might temporary go down but if so, it will rapidly bounce back. It could however mean a changed view on initiatives such as the reusable cups introduced at certain coffee chains. People are also probably less interested in the packaging-free shops where you fill loose product in a bag of your own.
Sustainability is also related to the expected increase in general demand for hygiene. Packaging might even become appreciated by the consumers. It is visibly protecting and guaranteeing the freshness of the product. This could also be supporting the introduction of track and trace systems to a broader use. Blockchain technology is available, among other solutions, and is implemented as a useful tool in the distribution chain. This crisis could be a catalyst for increased use of technology for tracking and to guarantee the product origin and what it has experienced before consumption. An increased cost is hard to get around and can, in particular now, be a disadvantage.
It will take a while for the world to get back on track and increased unemployment and uncertain employments will make the average consumer more price sensitive than usual. The result comes as a shift towards a consumer demand for more value-products and private labels will have a field day. Converters and others in the packaging industry will not be spared the requirements for lower prices.
The future is right now not bright, but it is not a dark abyss either. We will have to adopt and be as agile as we can to survive and succeed also in the new tomorrow.
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.
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.
A new and purpose-made design can involve minimising size and weight, leading to concentrates and container reuse.
2019 looks like another big step forward for e-commerce, across categories. The final statistics might not quite in yet and the growth rates might not be as huge as a few years ago but the share of all retail is definitely growing, with consequences for the entire value chain.
One estimation is that, globally, the total growth of e-commerce in 2019 was 21% taking the online share of total retail sales up to a staggering 14%. The numbers vary strongly between categories and we are looking forward for the dust to settle and to get the final numbers for 2019.
As brand owner you respond to this shift in purchase patterns and adjust the offer, products and packaging to online shopping. One main consequence from a packaging/logistics point of view is that products are no longer shipped neatly stacked on pallets protected by secondary packaging.
Online shopping means the opposite for a shipped product. It could be sent alone to be delivered at a doorstep or be dispatched together with random products to a pick-up point, probably both. In any case the product will need more protection than the standard primary packaging can provide.
The situation is improved either by adding more and protective packaging, changing material from glass to plastic or why not design the packaging and product for e-commerce, or omnichannel, from the beginning.
A new and purpose-made design can involve minimising size and weight, leading to concentrates and container reuse.
Unilever has decided to make all their plastic packaging reusable, recyclable or compostable by 2025. To get there they are, among other things, offering shoppers refillable containers. This also works well for online shopping where the smaller sized refill units are saving weight and cost. Cif household cleaning products are offered as concentrated refill capsules for the original spray bottle. Just add water and hey presto the product is ready for use. Unilever is also part of the Loop initiative where a whole range of products are offered online in refillable containers.
Another similar product concept from a leading brand owner is Pepsico’s Drinkfinity, also an example of a concentrated product sold in shipping friendly containers. The concept consists of juice-based pods and a reusable water bottle. Just add some H2O. This is probably also a move to meet a shift in consumer demand for more healthy products. Nevertheless Drinkfinity was launched online where the product has an e-commerce site of its own, just like any other direct-to-consumer brand.
Perso is a L’Oreal concept that takes this a step further. Perso is a device that actually makes personalised skincare products for you, in your home, and is powered by Artificial Intelligence. From the three cartridges contained in the machine it makes unique skincare, lipstick and foundation products, just for you. All personalised as you have fed the thing with pictures of yourself, location and your preferences. This is what you can call reusable and smart packaging.
The concept of concentrated, space saving, light weight products has many positive sides. It saves cost, it is a great way to streamline online sales logistics and maybe it even gives the consumer the satisfaction of a “homemade” product.
The mantra in the packaging industry has for some time been Recycle, Reduce, Reuse. Recycling material is great when there is a demand for the recovered material and reduced use of material is good for both the environment and the budget. Reusable packaging is more complicated in many ways, in particular for food products.
The reuse concept has developed since the olden days of refillable glass bottles and today has an appeal also as an alternative to Single Use Plastics items for the foodservice industry and has a potential to improve environmental footprints for the e-commerce industry. It can also be a great marketing tool for food and beverage brand owners and a way to reach specific consumer groups. Below a few examples of reusable packaging spotted along the way.
Food service
Hot drink cups with a deposit are now available in several cafés and restaurant, although in a small scale, where you pay up an extra dollar, pound or euro for your coffee, which then is returned when the container is returned at the bar.
Australian Returnr is taking the concept one step further when offering a series of foodservice containers. Not only cups but a whole range of reusable cups, bowls and lids that are designed for multiple use and also for takeaway. The aim is to support cafes and restaurants to eliminate single-use takeaway packaging. Returnr cups and bowls are, in Australia, free to borrow from cafes and restaurants with a $6 deposit. The deposit can then be claimed back from any restaurant who are working with Returnr. Something that attracts not only local cafés and restaurants but also Deliveroo who are offering Returnrs containers to their customers.
E-commerce
E-commerce as such is developing very fast but is from a packaging point of view there is plenty of room for new ideas.
RePack is an example of this. RePack is a packaging solution made specifically for e-commerce. It is a resealable and durable plastic bag in varying sizes that close with a zipper. It is unique though as it is made for reuse and linked to a deposit system. The reusable packaging itself is made from recycled materials and is space efficient in that it is flexible and adjustable to minimise air, saving money and resources. When the consumer receives the delivery, they return the now empty bag that is designed to fold back into letter size which simply is dropped in the nearest mailbox. The consumer incentive lies in the refund that comes as a discount on the next purchase. Back at RePack’s logistics hub the bag is cleaned and sent out to be used again.
Food and bev brand owners
Online grocery shopping is also growing very fast albeit from a small base and has some catching up to do compared to other segments. One significant example of new thinking is from Loop who promote reusable packaging for grocery and personal care products.
Loop is an interesting grocery e-commerce concept including a deposit-based refillable packaging scheme. It starts when a consumer order a home delivery where the Loop products arrive in a bespoke crate. With the following doorstep delivery of Loop products the empties are then picked up and returned for reuse. The packaging used is bespoke and made to be returned, cleaned and refilled. Materials used are metal, glass and plastic. Leading FMCG producers like Unilever, P&G and Nestlé have joint forces with TerraCycle an American recycling company to organise the Loop model. It’s in use in North America and in Europe the system is, at present, used by Tesco in the UK and by Carrefour in France.
Reusing containers is intuitively a good thing to do but the entire operation has to be considered, from start to landing. More transportation is usually needed, washing and rinsing using detergents and more material is normally used. When it comes to packaging it is never going to be simple but packaging reuse is definitely a path to explore. Looking forward to following the developments.
