We have a lot of options for materials that completely decompose. The challenge is materials that only decompose when you want them to, and not while theyre sitting on store shelves
That doesn't sound like a problem but a feature. We love new shiny things and wasting things.
I think if we find materials that breakdown in a useful way, it creates an incentive to make use of those products that have a shelf life. But more importantly creating a waste product that is beneficial.
I didn't know if the material science is there yet. But we need to figure out the best way to use these new materials to change industries.
If we can make something profitable, other people will do the hard part of adopting it and getting it out there.
My work produces sooo much waste. More than all of the staff combined will ever produce. And thats just my branch. We have hundreds of branches and being where we are in canada, we put some of the most amount of effort into recycling. Because its law, not because the company is willing to sacrifice profit by spending resources on anything that doesnt produce value in dollars.
We are small fry, and we arent in a monopoly
Cardboard. It composts well.
I go through more cardboard than garbage. It's not useful for many packaging or shipping solutions
Right, generally whenever fluids or outdoor exposure is a concern. Because it decomposes.
In not sure what point you are making. But ill clarify that i was only trying to show that i did take the use of cardboard into consideration when i have the opinion i did.
That may not help or already be understood.
I dont know what happening
We have cardboard and paper for when you want packaging to eventually decompose. And plastic for when you dont want it to. Which is why no decomposable alternative for plastic has caught on, plastic is mainly used in those situations we dont want it decomposing. A lot of people have developed plant based, biodegradable plastics, its actually not that hard. Theyre just all prone to decomposing
Glass? We used that for decades.
Of course, glass is brittle and in most cases loves to break into sharp pieces, so people don't love it for a lot of applications, particularly in packaging/shipping. When glass is involved, it generally demands more packaging to protect the glass from breaking.
Almost all of the plastic I use at work so ship orders, is used for less than a day. Tape, plastic bags, wrap, strapping.
We use so much of it to just contain things for extrememly short periods of time, its all disposable plastic that isnt needed for more than a day usually, often hours.
Nothing about does anyone think even once we dont want it to decompose too soon
We we are one industry, and just one branch of one player in it. And we are one of the few areas that has rules about recycling.
Industry can change if they want but they dont.
We could easily switch to paper tape and start there at least eliminating one entire product line from waste. But if we can just straight up swap oil-plastic tape for biodegradable-plastic tape it would be one example of something we can do right now that we won't until we are forced to
All it would take is the product be available and the cost not more than what we are using. So subsidize the cost of using the product we want to lower its price and get people using it. When they do scaling and maturing of this new product will also bring the cost down which will reduce the need of subsidizing it, over time or sudden advances, and make the bad product less appealing because of cost.
But you have to make that transition as easy as simply ordering a different part number when ordering supplies.
Its never going to be industry that makes this happen unless it costs less. So it will likely need to come from government whether it be economic policy or legislative policy
The problem with cardboard isnt that it decomposes, but that its made of paper, which absorbs fluids. Its also not really possible to make air-proof packaging with cardboard.
I wonder why we shifted away from things like waxed paper milk cartons(like the small ones you'd get in school) and waxed butcher paper?
Is waxed paper/cardboard product really that much more expensive than plastic in terms of packaging?
Here in Germany, all milk is still distributed in cardboard packages
you mean cardboard packages with plastic linings ?
They are a fucking nightmare to recycle. You'll be lucky if they get burnt and I mean that.
Yep. You can get it composted quickly enough, you can get the plastic film out of the composting bin, but the microplastics are already seeped in and contaminated the biomass.
Yeah, but the inner lining of tetrapacks is plastic
Because wax production has numerous negative impacts on the environment: higher energy costs (which lead to higher product costs), deforestation (in case of soy or palm based wax), impact on bee population (in case of bee wax), etc.
Plastics are just better materials for pretty much everything.
