The world wants to go green. 73% of consumers say they ‘”definitely or probably” will change their consumption habits to reduce their environmental impact (Nielsen), presenting a huge opportunity for food manufacturers.

So what are the eco-friendly food packaging options available to the food and drink industry right now? Today we look at eight eco-friendly food packaging trends sweeping the globe, and discuss some facts – and fiction – of environmental product packaging.

8 eco-friendly food packaging trends:

  1. Compostable food packaging
  2. Bioplastics
  3. Biodegradable food packaging
  4. Recyclable food packaging
  5. Reusable food packaging
  6. Optimised food packaging
  7. Eco-friendly logistics packaging materials
  8. Eco-friendly packaging for pet food

1. Compostable food packaging

Compostable food packaging is designed to be a more sustainable option. It’s often hailed as a non-toxic, alternative food packaging that creates less plastic pollution by breaking down into soil if it’s released into the environment.

But, there’s a bit more to it than that.

Hot compostable food packaging

A lot of compostable food packaging is made from a polymer called Polylactic Acid (PLA). PLA can’t be broken down in a typical home composting environment. It needs temperatures of over 60C – which is hotter than home compost will get – so needs an industrial facility to first shred it, then treat it under sustained high temperatures. If you dump compostable plastic in a landfill or backyard compost heap, it won’t break down properly at all.

While commercial composting facilities are becoming increasingly widespread, many countries (even countries offering compostable plastics) still lack the infrastructure and dedicated collection systems, making this a less appealing eco-friendly food packaging option than more sophisticated home-compostable alternatives.

What’s more, PLA can’t be recycled via the normal recycling streams, and will contaminate regular recycling batches if put out with conventional recycling, so typically is best disposed of in landfill.

In short: think twice before opting for PLA-based food packaging, unless you have the full product stewardship system in place to deal with it.

Home compostable plastic packaging

If your company is to offer an eco-friendly food packaging option that users can compost at home, you need to invest in packaging products that are certified. This means they are backed up by a authoritative certification, such as:

Searching for local packing providers certified by either of these schemes is the best way to access the growing range of genuinely compostable food packaging products.

2. Bioplastics

We’ve separated bioplastics into their own trend because there is more to the subject than just PLA. So, let’s dig into it.

What is a bioplastic?

When we use the term ‘bioplastic’ here, we’re talking about plastic that is derived (fully or partly) from a biomass, or material of biological origin rather than from fossil oil. Examples include PLA, starch-based polysaccharide and PBS.

The term is often overused, however, leading to some confusion over what is and is not actually a bioplastic, and what customers should do with these products when they are finished with the packaging. For example, many bioplastics aren’t biodegradable, and must be thrown out or recycled like normal plastic. Such materials include PTT and biobased PE and PET.

There are also normal plastics (i.e. called fossil-oil based plastics) which are not plant-based but can biodegrade.

Offering bioplastic to your customers

Switching to bioplastic is usually a better, more eco-friendly way to sell products than using fossil-based plastics – many can be manufactured in a more sustainable way, producing as much as 80% less greenhouse gases than, say, polystyrene (Ingeo).

That said, regulators are watching brands for how they market their plastic to consumers. You’ll have to be careful as to your claims regarding what your packaging is capable of, and what people are meant to do when they are finished with it. For example, in New Zealand, claims that a product is ‘recyclable’ when in fact it can only be recycled in limited facilities, could risk a fine from the country’s Commerce Commission.

Of course, the easiest way out of that risk is to be honest on your labels.

Plastics derived from bio-mass

Plastics derived from bio-mass can be a more sustainable alternative.

3. Biodegradable food packaging

We’ve used the word ‘biodegradable’ here a few times, and the phrase is booming in popularity both at the manufacturing and consumer level. But, biodegradable packaging doesn’t always do what you think it does. If you want to truly invest in eco-packaging, you need to know how to spot the good and bad biodegradable plastics.

What should ‘biodegradable packaging’ really mean?

Biodegradable refers to plastic that can be broken down in an organic fashion (eaten by microbes, essentially) and turned into biomass, gas or water. But, once again the term can be a bit loose – and manufacturers of so-called biodegradable products sometimes do not offer timeframes for the degradation process. This could mean that their plastic still takes years and years to degrade in any noticeable fashion.

  • Quick fact: The UK’s University of Plymouth tested several plastic products for their degradation and found that a number of biodegradable shopping bags were still so intact as to be sufficiently strong to carry shopping after three years of being buried in the sea and ground.

So how do you find truly biodegradable food packaging?

Be alert for ‘green-washing’ – that is, products that claim to be environmentally friendly but are vague on how, or don’t live up to the claim. ‘Biodegradable’, unfortunately, is one term that’s notorious for being used to green-wash plastic packaging products.

See if you can find out the timeframe for the biodegradability of any plastic packaging you intend to use for your food or drink products. If it takes longer than a year to degrade; if it breaks down into micro-plastic instead of biomass – or requires a special facility for which there is limited infrastructure, it’s not going to be as environmentally friendly as you think and you’ll struggle to market it to consumers.

When hunting for compostable products as opposed to biodegradable, look instead for the certifications as mentioned above.

4. Recyclable food packaging

In the hierarchy of eco-friendly food packaging options, many people consider recyclable packaging to be better than biodegradable but less desirable than compostable (where composting facilities are available). This is because they can be turned back into raw materials to be used again, whereas biodegradable plastic just breaks down – so everything put into creating it is, in a sense, lost when it cannot be reused.

However, recycling is different everywhere you sell – cities all offer different options, and consumers aren’t always sure what to do. So, what are the most recyclable food packaging materials on the market?

The 5 most recyclable food packaging materials:

  1. Reusable packaging (see below). If customers can avoid having to recycle, that’s always best.
  2. Paper. 68.2% of cardboard generated in the US in 2018 was recycled, the highest rate out of any material (EPA).
  3. Aluminium. Aluminium is generally considered easier to recycle than glass, however it’s safer for the planet to make new glass than new aluminium. So, if you can find already-recycled aluminium, that’s excellent (it can be recycled indefinitely). On the flip side, strong demand for new aluminium can be quite damaging for the environment.
  4. Glass. Glass can also be reused indefinitely making it a great recyclable choice. But, facilities to recycle glass aren’t as common as other products so you have to take into account the recycling plants available in your sales areas before committing to glass packaging. It’s also heavier to transport, which adds to overall fuel use.
  5. Plastics 1 and 5. Most plastic can only be recycled a handful of times before it loses too much quality. PET (the plastic with the Resin Identification code – or ‘recycling number’ 1) is considered a desirable recyclable plastic, as is Polypropylene (number 5). On the other had materials such as Polystyrene (6) and LDPE (4) (like soft plastic bags) are rarely recyclable.

5. Reusable food packaging

Recycling is great and the world needs to do more of it, but the recycling process of breaking materials down and reforming them still takes energy and creates pollution.

By contrast keeping food packaging out of the waste cycle and reusing it in its original form is virtually always a better option. Indeed, research company PreScouter labelled reusable containers as the future of the food and beverage industry.

For a product package to be reusable, however, it has to be robust. This often rules out paper as an option, with companies preferring materials such as stainless steel, silicone, glass and robust plastic.

Reusable packaging ideas in use by popular brands

  • Stainless steel coffee cups with silicone lids
  • Takeaway food containers made of robust plastic
  • Glass jars with metal or plastic lids – bonus points if the label can be easily peeled off
  • Silicone containers with plastic lids

Offering your customers readily reusable containers is a tactic that’s been adopted successfully by food companies seeking to differentiate themselves with eco-friendly packaging.

Barriers to the widespread uptake of reusable packaging

Cost and convenience are two of the biggest barriers to reusable packaging growing more widespread.

As a food manufacturer, you’ve probably already looked at the list of packaging materials above and balked at the costs that come with mass-producing products in something like stainless steel.

Convenience is also a factor. Many brands offer discounts for any customers that can return their reusable packaging (again, more common at the retail end), but if customers can’t be bothered doing this, the effect is entirely lost.

For now, manufacturers must be clever about how they offer reusable packaging. For some, it’s a customer experience differentiator (i.e. personalised packaging). Others use it as an excuse to adjust business model or product, like Blueland that is offering dissolvable cleaning tablets instead of liquid soap (to be dissolved in reusable bottles), or Algramo which is placing vending machines in stores so customers can refill reusable containers at low cost.

Innovations in reusable packaging

Other innovative models now available include packaging as a service systems, such as Huskee Swap, which offers a reusable coffee cup wash and replace service.

Meanwhile Sydney-based B2B coffee manufacturer Kua Coffee has gone zero waste with its packaging, in part by using Unleashed Software’s serial number tracking system to follow all of its reusable coffee drums, which are recorded as an asset on sales orders and checked in and out of their warehouse as they dispatched and returned.

6. Optimised food packaging

Optimising food packaging is another trend gaining traction around the world. Here, optimisation refers to making packaging better or more efficient in some way – minimising the amount of packaging, or making it thinner/lighter.

Where manufacturers can’t turn to bioplastics and the like, optimising packaging instead (or in conjunction with more eco-friendly materials) can be a way to reduce the carbon footprint of you packaging while also cutting costs.

Of course, there are barriers to this and it isn’t right for everyone. Here we’ve listed out some common pros and cons to help you understand if optimised packaging might be right for you.
Advantages of package optimisation

  • Reduce carbon footprint by using less material in packaging – for example less interior filler or plastic wrap, smaller product labels, or using a greater proportion of eco-friendly materials.
  • Cut the cost of packaging, again by using less of it. An example here might include shrinking the thickness of glass, or replacing triple-walled corrugated cardboard to double.
  • Cut logistical costs by reducing weight, perhaps by moving to another material (i.e. from metal to bioplastic or paper).
  • Pass reduced costs on to the customer.

Barriers to package optimisation

  • There is usually a trade-off to be had when reducing weight, for example in packaging durability.
  • Regulations in certain industries can hinder packaging innovation.
  • A lack of more eco-friendly materials, or a lack of the facilities required to recycle or compost them, means they aren’t always much better than the alternatives.

7. Eco-friendly logistics packaging materials

Even if you find ways to reduce the carbon footprint of your individual products or cut costs by optimising the package design, as soon as you load it all up for freight transport you will almost immediately come across more plastics: think packing peanuts, bubble wrap, and shrink wrap.

There are, however, eco-friendly alternatives here, too. Such examples include:

  • Biodegradable packing peanuts
  • Corrugated bubble wrap
  • Packaging made out of recycled materials
  • Packaging made out of organic materials

Sustainable pet food packaging

Sustainable pet food packaging is a major trend, with the number of solutions available to pet food manufacturers growing accordingly.

8. Eco-friendly packaging for pet food

Pet food manufacturers are also able to contribute to the good health of the planet thanks to the raft of advancements being made in pet food packaging. This is good timing, too, as a Trivium Packaging report found that 74% of pet parents would pay more for sustainable packaging, and two thirds said environmentally friendly or recyclable packaging is important to them.

The same environmental concepts of reducing, reusing and recycling can all be applied to pet food manufacturing. In one success story, Earth Animal, Pet Food Experts and the Pet Sustainability Coalition jointly ran a campaign in 2020 to collect flexible plastic pet food and treat bags from US consumers to be sent on to a recycler for the second phase of the test (grinding the plastic into pellets that could be upcycled into new pet products). The collection exceeded expectations – consumers proved willing to bring back their plastic, and now the second phase can proceed.

What can pet food manufacturers do to become more eco-friendly?

The short answer is to follow the same advice as in the rest of this article. Look for materials that can be optimised or easily recycled, and if using plastic then seek out either certified compostable materials or biodegradable materials that biodegrade properly.
