I imagine all plastics will be out of the question. I’m wondering about what ways food packaging might become regulated to upcycling in the domestic or even commercial space. Assuming energy remains a $ scarce $ commodity I don’t imagine recycling glass will be super practical as a replacement. Do we move to more unpackaged goods and bring our own containers to fill at markets? Do we start running two way logistics chains where a more durable glass container is bought and returned to market? How do we achieve a lower energy state of normal in packaging goods?

Cellulose. Wax paper. Stuff made from seaweed and mushrooms.
This answer isn’t getting enough upvotes
Amen to that. Seaweed food packaging. I know of some people trying to get this accepted at big companies eg airlines. Their kids made a whacky video about plastic’s impact on marine life. Behold: https://www.youtube.com/watch?v=mT4BVDbXS1Y
The problem that strikes me reading through this thread, and similar conversations about packaging, is that we can do all we want to reduce packaging and plastics at the consumer end, but there’s a huuuuge amount of packaging all the way through the supply chain. From farming supplies, to ingredient packaging, and the packaging used to transport food products to stores. By focussing solely on the consumer end we’re not addressing the whole issue. It’s like the obsession with bamboo toothbrushes and paper / metal straws. They’re consumerist solutions to a problem caused by consumerism.
Speaking of greenwashing I still remember laughing my ass off when I unwrapped a plastic cover for a paper straw, which made it even funnier is that before then, they would wrap plastic straws in paper wrapping, so why they didn’t just use that is completely beyond me.
I remember cheering sarcastically the first time I saw a paper straw actually in a paper wrapping.
But I bet those paper packages of paper straws were bundled into cartons that were wrapped in plastic, and then those were wrapped with other bundles in more plastic. And even if they’re using cardboard boxes as part of that packaging who knows what percentage of that is recycled, or made from recycled waste. Anyone that’s worked in retail knows the incredible amounts of packaging that get binned every day that’s invisible to consumers.
Exactly, there is so much industrial waste before a product makes it to you. Yet everyone focuses on the consumer use which makes it inconvenient for the end user and ignores all the “invisible” waste which would require investment from businesses to fix but would have a far larger effect on the environment. Not being able to get a plastic straw or PE film bag doesn’t really improve anything since the alternatives are worse and in many cases far worse for the environment even when reused.
Which is cheaper, switch out manufacturing processes and change the whole industry, or tell the consumer in a commercial that it’s all on them?
Not really the manufacturing processes, but how individual parts are shipped and protected in transit. But yes, that is my complaint, put all the onus on the consumer without actually making any real improvements because the government isn’t mandating it.
Farming supplies? There is very, very little that we use farming that isn’t stored or transported using reusable containers like trucks, tanks and hopper bins. The most plastic we would use is things like silage tarps or netwrap that get thrown in totes and recycled.
The packaging starts long after it leaves the farm.
Which country are you in? Where I live my food comes from all around the world. Recycling is mostly a Western thing. It doesn’t exist in many of the countries that supply our food. I was just going by the amount of crap I’ve seen in many agricultural areas. Plastic sacks, containers etc.
Canada
So according to this link https://www.ciwm.co.uk/ciwm/knowledge/agricultural-waste.aspx
"Plastic packaging waste from agriculture represents approximately 1.5% of the overall volume of plastic packaging in the waste stream in England. The types of plastic wastes arising can vary and be both bulky and dirty often making the management of these wastes difficult. Around 135,500 tonnes of agricultural plastic waste is produced each year in the UK with;
Approximately 32,000 tonnes being produced from plastic packaging waste; and Approximately 103,500 tonnes being produced from Non-Packaging Plastics (including contamination)."That’s just England. The data is old (2003 I think), and yes 1.5% is not huge, granted, but that’s of total plastic waste, not just from the food chain. A lot of our produce comes from Asia and North Africa where generally there just aren’t the same facilities for recycling, and environmental issues are not as prioritised. It’s great that there’s very little plastic waste in your farming methods, but it’s not the same around the world.
That’s probably an economy of scale thing. On a 5000ac farm, we’ll use hundreds to thousands of liters of every variety of chem and the product is measured in the millions of kg. So using small, non-reusable containers is just a pain in the ass, regardless of the waste it generates.
So all respect due to UK or other countries in Europe, but they’re small potatoes (no pun intended) in the food production scheme, and their waste to end product ratio will be drastically out of whack to the main source of agricultural products like US, Canada, Russia, Australia and Brazil/Argentina. And I know that we aren’t much different in our production methods to those other heavy hitters. So, you’re right, agricultural methods aren’t the same around the world, but when you get into farming at scale, that’s how things are done.
Ok, but we’re getting dragged into a tangential debate about farming when really my point was that we need to look at waste through the whole supply chain, from farming ingredients to getting put on the shelves. I’m sure we could pick apart the contribution of any one part of that chain and debate how significant it is. Together, at all points in the chain, there is plastic waste that the consumer doesn’t see.
(And btw Canada isn’t in the top 20 of global producers, according to the IMF / CIA World Factbook as at 2018; the EU is number 3 https://en.wikipedia.org/wiki/Agriculture)
Edited to add: this 2022 UN report states that plastics are used extensively in agriculture and goes into how they are used and how they enter soil and water supplies: https://wedocs.unep.org/bitstream/handle/20.500.11822/40403/Plastics_Agriculture.pdf
And this is another UN report on the issue, stating that Asia is the largest user of plastics in agriculture. When China and India are two of the largest agricultural producers, that’s an issue https://news.un.org/en/story/2021/12/1107342
Mostly in Florida citrus, the packaging for pesticides is significant. Jugs for liquids, bags for dry powder. And irrigation drip and emitters are all plastic. Oh and cones for new trees from the nursery, zip ties for the protective cover around the stalk of newly planted trees. Flagging tape, um, there’s probably more.
I’d figure at any scale that they’d be using 500L deposit totes for chem and liquid fert. A lot of the rest of it sounds like equipment. A zip tie for a tree that’s going to produce for 15 years isn’t much in the scheme of things. Now when you see that apple individually wrapped in plastic at the store, that’s the sort of thing that should grind your gears.
Citrus does not have the scale of the big crops like corn and wheat, so big deposit totes. I am close to the industry, pesticides are sold by the jug or pack, packed on pallets, poured into sprayers by hand. I’ve known growers that just throw the waste into giant burn piles. Doesn’t matter, citrus is dying…unless we come up with a solution to citrus greening.
I would love to see increased standardization in the food industry limiting the possible sizes and shapes of containers (such as glass) making them easier to wash and reuse as-is. On the home front, for example, it’s ridiculous that I have to go out and purchase brand-new Mason jars for canning instead of being able to reuse a store-bought salsa jar. But more importantly on the commercially-processed food front, standardization would make reuse easier by ensuring that containers do not have to return all the way to their original company; that way a jar used by a raspberry jam company in the Pacific Northwest bought by a customer in Florida could go to a local orange marmalade company for reuse rather than having to travel all the way back to the PNW.
I think should also start seeing a lot more compostable products. We’re already getting there somewhat with paper replacing plastic in shipping, but more products need to be explicitly labeled as compostable, and more municipalities need dedicated compost pickup and processing facilities. It’s insane that we’ve created a soil-to-landfill pipeline for nutrients.
The idea of a standardized container that is so sexy. Bonus points if it comes in a variety of sizes that perfectly scale and tesselate together.
Like the plastic containers you get from Chinese restaurants?
I live dangerously- I make yogurt in old jam jars!
…Though you only need to go to 180° and don’t need pressurization for it.But I absolutely echo you with that, the fact that you can’t use most glass for this is insane.
And I only use the Baba Maman jars, they’re the only ones resilient enough.
I expect they’ll move back to earlier packaging materials like glass, metal tins, and waxed paper.
Why do we need the expense of returning glass bottles for washing and reuse, when glass recycling works and is much cheaper?
Washing and reusing is much more environmentally friendly than recycling. It may be more expensive because of the current societal/legal environment but given the right incentives, it doesn’t have to be.
It would be amazing if a standard glass bottle was adopted. That way they can be collected, cleaned and reused by any beverage company.
German beer/water/juice bottles are mostly standardized. There are some massive warts in the system unfortunately: The deposit is legally mandated but the bottles are private standards. Hence breweries/bottling companies are increasingly deviating from the standard bottles for marketing reasons. And there’s a separate single-use flimsy-plastic deposit system used by discount stores which is very effective at collecting bottles for recycling but doesn’t foster reuse.
However, I find it ridiculous that we’re transporting all that water at all even though tap water here is at least as drinkable as the bottled water.
beer
The usual 0.5L beer bottle:
water
A couple of different types here, some 0.7L, some 1L, some glass, some plastic, but all multi-use deposit bottles.
I was not under the impression that glass recycling penciled out (as in, it costs more to recycle than make new). My area crushes “recycled” glass and uses it to cover landfills (which is better than having it inside the landfill, but it still leaves the consumer system).
With return policies we don’t need to go through actual recycling methods. I don’t know if growlers are popular in your area but it’s pretty cheap energy-wise to just sanitize a returned jug.
Reduce, Reuse, and Recycle… specifically in that order.
when glass recycling works and is much cheaper
[Citation needed]
Those aren’t really good either. Even glass, as much as it is better, still needs yo be washed and reused which uses more aggressive chemicals than most would be comfortable with.
Fact is that like everything in life, stuff is a tradeoff. Can we wash and re-use glass without aggressive water harming cleaning fluids? Sure. But that means more danger from it. We could also use degradable plastics but those are problematic as well. Tins are an issue in general plus they can only be used for some foods. Waxed paper is even trickier to recycle than most other things, not durable, and again only suited for some foods.
Ultimately, it’s health vs recyclability. There’s always a tradeoff.
As fireweed said, I think it is too energy intensive especially with the contamination issues.
I think it would be interesting if packaging in many areas was standardized to actually useful products, like if products came in aesthetically designed drinking glasses and dinnerware.
I think it might be more effective to ask how this is/was done in other parts of the world presently. I’ve never been outside of North America except for visiting Hawaii once. I’ve seen documentaries about foreign bazaars and know the basic history of the Roman Fora, but I don’t know how this translates to or evolves to meet the needs of Western culture presently and visa versa.
It takes around 70% more energy to melt glass into glass than to melt sand into glass.
Aluminum is pretty great, as is paper for a lot of products
At the end of the day I think the answer is less availability and more local production is the way to go. Heavy sustainable packaging uses to much fuel. So it is better if we can grow and produce locally so we can theny recycle locally back to the packers and producers.
We can grow anything indoors now. We can bottle anything locally. The larger issue is electronics. Which can use sustainable materials.
I wish we could tax corporations for trash produced. Have the dump sort trash by company and offer them to recycle and charge them to recycle or trash the items.
Local production is counter-intuitively worse because you have more people hauling less produce. Even in a clean energy paragdime that’s just excess waste. We need to find a way to be sustainable at scale
? If it is produced locally then food wouldn’t come across the world. Lots of meat and produce comes from California or China for northeast America. Less people hauling anything the better. Like we can grow in a building in the city way more efficient than long hauling.
Can regions support the population with local food growth.
You need good soil, and water and the right climate and space to do it. That is kind of why we went away from local food growth in the first place.
Currently were i live we have 4 seasons significantly. We have farmers markets in the Summer and Fall but all of that goes away in the Winter and spring because they can’t grow food year round.
I guess we can now build out physical structures where you can grow inside where we can monitor and control everything. I don’t know how that compares to traditional fields.
I just want to be sure this isn’t a best intentions but unforseen super bad consequences.
We have also been spoiled with the variety of food we have everywhere. I can almost buy every type of food the world has to offer because of the huge transportation industry we have.
Why I said less availability. We can also grow for 4 seasons indoors like you said and I implied. Especially if we get cheap electricity too. Long future we can super shrink the operation footprint size and all the inefficiency of sustaining a living creature and just grow the meat.
our current civilization is built on the division of labor. everyone could theoretically produce their own food and that would be more efficient but not enough people have the time or expertise so there will always be some form of moving produce to market and that will always be more efficient at scale.
Those wind powered container ships would be pretty good marketing for a green leaning company (hint hint)
In no way was I saying everyone growing their own food. We can grow 15-30 miles out of the city. We can stop outsourcing our manufacturing and growing thousands of miles away from where people are.
Kansas to New York is over a thousands miles that is wildly inefficient. Don’t get me started if we could get farms closer to trains that go to the city.
I am here to preach of cellophane. It’s not the perfect product right now but if we invest in it, it is fully biodegradable and jus plain cool.
Also, shoutout to PLA. Again not perfect right now but with the right implementation we can start getting rid of a lot of waste.
Plastics. I think your assumption’s incorrect. We’re going to keep using plastic.
Unfortunately, it will get less effective, because organisms will evolve to eat it.
the price difference and, well, its plasticity is unparalleled
nothing else comes even close within several orders of magnitude. the other options listed ITT are complete jokes. you think goods are expensive now because of a few points of inflation? imagine paying a few dollars extra for thick and heavy glass bottles for everything or fancy custom made seaweed mushroom compounds instead of medical grade sterile plastic wrap that costs 2c per football field
Non-plastic alternatives would also cause much more food spoilage which would also lead to increased food prices. Most people don’t understand just how incredible plastic is as food packaging.
Go to a grocery store, bring your metal containers to the grocery, get them autoclaved while shopping, and get em filled up with your rice/cereals/juice/etc.
Edit: The below is a bad idea unless new materials are found, see comment thread.
Also, SLA Printing for ceramics is already possible, just expensive for now. Once we figure out how to do that sustainability and in a foodsafe manner, we could just print our single-use cups and dishes from a slurry.
Yeah, finding the gunk from a bone dry ceramic cup left in random places outside would suck, but nature would be able to reclaim it as easy as any random dirt clod. (Well, not as quick in the short term, but when it comes to materials)
One could potentially even just rinse out the clay, stick it in some water, and with some elbow grease and effort, process it into actual, useable ceramics. Depending on the formulation required for the SLA process, of course.
I wonder what happens to ceramic when it degrades over time. Does it become microscopic pieces?
Well, in this hypothetical I’m proposing, there is no superheating involved- just printing, and being set to dry.
Ceramics get completely rigid, but relatively fragile in this state, which would be sufficient for a single use material, but if they’re soaked for long enough, would dissolve.
The term is “Bone Dry” and specifically how to reclaim bone dry clay- that’d probably give you an idea on how it breaks down/dissolves.
there would be no straightforward way to get it back into print media unless there were recycling centers, but if one cleaned the food matter off well, in theory it could be standard clay people could use.
Imagine collecting food cup clay and making it into bricks for public projects.
As a former ceramic artist I would be very wary of this solution. Bone dry clay is way too fragile to survive transportation unless very carefully packed. Potentially an air dry paper clay could work but even then it isn’t very durable.
As you mentioned in your comment, the minute bone dry clay touches liquid it starts to slake down. So you would end up with clay mush in your food and the structure would start to fall apart.
Additionally, silica dust from bone dry clay is really bad for you. Probably not very likely to effect the occasional consumer but people interacting with it often would be at an elevated risk for lung issues.
Interesting, I was under the impression that clay was inert when ingested.
The transportation and dust would be lessened from the printing process if it were done by the individual, but if what you say is true, then the whole idea is worthless unless there’s an alternative material available.
Most clay is likely safe to ingest. However the willingness of customers to ingest clay may vary and the quantity of clay may impart a flavor on the product.
I’m also not sold on the printing process. Ceramic is strongest when the clay platelets are aligned and in a 3d printing process there are many layers. Each of the layers introduces a weak point that is likely to crack in drying or use. Ceramics already have quite efficient methods for production primarily slipcasting and extrusion. In these methods pieces are formed without “joins”.
I’m also not convinced printing it at home would be feasible for mass production/adoption.
That being said it is an interesting idea. I think you could probably make single use, unglazed, low-fire ware like Indian Bhar. Which could get recycled into aggregate. Firing adds emissions back into the process though and I’m not sure where that ranks compared to something with an existing supply chain like paper alternatives.
I am talking about though is SLA printing though- resin printing, but without the resin, basically.
Which is why I think its more feasible than just extrusion printing on principle. The layers are incredibly thin, with no extrusion involved, and no exposure to air until well after the layers are formed.Hmm, that’s interesting. I’d be curious in how that would be cured and how the layers would stick together. Plaster might be interesting too since it has a faster setting period than clay.
Make the packaging edible while also not having it be destroyed by what’s inside in the process.
We’re not technologically advanced enough to do that yet, but I feel like this could be a delicious solution.
I like that idea too
I think we can only ever reduce the amount of plastic because literally almost everything is contained with some plastic. Even aluminum and steel cans are lined with plastic. Even paper packaging is lined with plastic. Personally I don’t think we can reasonably eliminate it entirely.
Deposit systems with standardized containers would be my wish. And I wouldn’t mind if some of the standardized containers were made of plastics.
I’d also hope for all sorts of concentrates and powdered drinks to take over. A large portion of the packaging we go through every day is actually for drinks.
Single-use bioplastics and fungi-based materials may also be part of the solution. Bioplastics would ideally be created from byproducts of other processes though.
