What are your solutions to our plastic waste problem?

Plastic packaging is a hot topic at the moment, with many in agreement that we need better solutions to reduce waste. Our guest and community member, Malcolm R, puts forward some plastic-saving suggestions and asks for your contributions.

In January, we discussed here on Which? Conversation ‘Who is responsible for reducing our plastic waste?’ and received hundreds of responses. I think we should be aiming to reduce packaging to only what is necessary. And, what we do use must – as far as possible – be recycled.

In his Spring Statement, the Chancellor called for evidence to tackle single-use plastic waste. So as a community of consumers, the question I put to you is: what is the solution?

Easy plastic packaging alternatives

There are a few key areas where I’ve noticed a lot of waste. Like liquids; do we always need bottles, or could it often be sold in pouches? Some places sell milk in plastic bags that can be decanted in a reusable jug.

And loose leaf tea and ground coffee are sold in bags, but instant comes in jars. Why is that? Why can’t we just buy refills?

Some packaging is arguably used for protection from handling damage like fruit, or to preserve it, like meat. But could there be times where we supply our own containers rather than buying contained food?

The same goes for ready meals and takeaways, which often come in plastic and aluminium trays and containers. I wonder if we really need these when we have our own reusable tubs?

Arguably, packaging makes the product look more appealing – a nice boxes of chocolates, Easter eggs and tins of biscuits to name but a few. But these are costly and discarded once they’ve been used, unless you can find a way to repurpose the pretty biscuit tin.

Making sense of plastic materials

When it comes to plastic, there are far too many different types in circulation, making separation difficult at recycling plants and adding complications to plastic waste being turned into new products. Here are some of the ways that I think this could be tackled:

  • Standardisation: can we standardise the different types of plastic to, say, clear PET that can be more easily separated and usefully recycled? I would even argue that all essential trays could be aluminium.
  • Markers: include machine-readable identifiers in plastics materials to allow automatic sorting.
  • Contamination: do we currently prevent recycling by laminating different materials, using foil, paper labels bonded to plastic? How can these be redesigned more effectively?

What’s the solution?

It’s time to review the packaging we use, starting by considering its necessity: what could be sold loose instead of packaged? Does it need to be contained, like a liquid? Does the packaging protect it?  And ultimately, could we reuse or repurpose it before we consider adding it to the ever-growing pile of waste?

We would like to hear your examples of packaging that you think can be improved – do you have any ideas or solutions on how this could be achieved? What examples have you already seen or heard of that could be used more widely? Please share your thoughts and ideas below.

A deposit should be charged on ALL glass bottles, no plastic bottles unless completely recyclable. ll eggs should be in cardboard, deposit on those as well as they used to do in The Netherlands, Firms should only use products for wrapping that are recyclable, We understand that times have changed and food needs packaging due to Health & Safety etc, Pubs and food outlets must use china & glass. Charge a deposit on glasses and a fine if they are broken, Then there are the nappies, for centuries there have not been disposable nappies, unless they are also recyclable then not allowed to produce them, Councils MUST fine companies and residents for not doing their recycling, WE MUST ONLY USE RECYCLABLE WRAPPINGS


I ordered loose bananas with my delivery from Tesco and they put them in a plastic bag. At first they said this would extend their life by 7 days, then they said they were “obliged to by law”.

Is this true?

They also put my loose tomatoes in a plastic bag and a bottle of bleach – already in a sturdy plastic bottle – in a plastic bag…

It seems telling them not to is not an option.


My guess is that they could argue that should do this as a consequence of UK Health and Safety law, as reasonable precautions to prevent your bleach from leaking onto your bananas and tomatoes.


Companies are not obliged to put bananas in plastic bags. Many years ago I used to tell Tesco checkout staff that nature had provided bananas with a biodegradable wrapping, remove my bananas and give back the bag. Putting bananas in a plastic bag will actually shorten their life by accelerating their ripening. Bananas give off a gas called ethene (ethylene) which accelerates ripening of bananas and some other fruits, which will shorten their life. You could give them a science lesson next time they make a false claim. 🍌

The Tesco checkout staff act more sensibly now, at least where I live, but I have not had any deliveries from them. Excessive use of plastic bags seems to be a problem with other companies too.


I suspect it helps to have loose fruit and veg – smaller ones certainly – in plastic bags to help weigh them. And I wonder how many shoppers would object to having them just tipped loose among all their other shopping? It might be better if we got into the habit of taking a bag or bags with us for such loose items; I’m all in favour of avoiding single-use packaging.


I find that bananas that have just been brought from the warehouse or have spent time on a chilled shelf are covered in condensation that could dampen other shopping so I always put them in a plastic bag which I later reuse. I would prefer it if supermarkets provided paper bags for produce but they don’t.


I agree about the paper bags John , as a real live example, I bought two plastic sealed bags of Jersey Royal potatoes , days later , due to the heat, evaporation took place , having nowhere else to go the moisture rotted the potatoes .


Yes this does happen sometimes if there is no ventilation and I can’t bear to see Jersey Royals go to rot so I eat them as soon as possible after purchase.
