Posted · Excessing packaging and spool waste

I love my Ultimaker printers, but I'm always horrified by how wasteful the filament spools are in terms of packaging material and the super-heavy plastic spools. I throw the spools and the cardboard packaging into the recycling bin, but the more I read about problems with plastic recycling, the more I realize that we need to drastically reduce single-use materials instead of relying on recycling.

 

Ultimaker, please stop using such heavy plastic spool for your filaments - either make the plastic spools much, much lighter, to reduce the amount of plastic waste, or switch to something more environmentally friendly, like recycled cardboard or some other recycled natural fiber.

 

I'm strongly considering switching to a different brand of filament (even though I hate how easy it is to use UM filaments) because I can't stand how wasteful the UM filament spools are.

    Personally, I am not convinced that cutting millions of trees to make cardboard, in order to replace plastic, is an environmentally friendly solution. You can not recycle paper and cardboard endlessly. After 2 or 3 times, the fibers become too short, and the cardboard or paper crumbles apart. As we already see in paper bags for fruits and bread in our shops today. Then new trees have to be cut to make new usable paper. So, each second or third paper bag you use, is made from a freshly cut tree, destroying forests.

     

    Long ago the whole earth (land) was covered in green forest, including all current deserts, and even Greenland. But over the ages, all that green, carbon and life got burried underground in the form of black coal, brown coal, turf, etc. In the sea, dead life forms decomposed into an oily gel and sunk. Those gels decomposed further into gas and thinner oils due to the heat in the earth. As tectonic plates moved and got buried, some oil and gas got stuck under land now.

     

    All this buried carbon can no longer take part in life, and thus life is bit by bit extinguishing on the earth's surface, as life-carbon gets buried underwater or underground. Plants and trees die when the CO2 level in the air drops below 0.02%. We are now at 0.03%, barely above this level, and lots of plants are already in bad condition and dying. For optimal growth, plants need at least 0.12% of CO2 in the air, but preferably around 0.3%, thus 10x more than now. Then all plants would grow 6x to 7x faster than now by themself, without us having to do anything. All deserts would become green again automatically. Sea levels would drop, because lots of water would then be contained in the wood and leaves of trees, and in the ground around their roots. And temperature would first drop and then stabilise: we all know that in a forest the temperature is cooler and more stable than in a bare desert like the Sahara. In mountainous areas, trees would grow up to much higher areas than now. There would be lots and lots more food and more habitat for all animal and human life. This is all proven in scientific experiments.

     

    So, to save life on earth, we should dig up all buried carbon, thus all coal, oil and gas, and burn them, so that this carbon can take part in life again. But we should burn it in a *clean* way, with good particle filters and catalysts, so the only combustion products are life gasses water vapour (H2O) and CO2.

     

    In formula:

    - For plants: CO2 + H2O + E (sun energy) ---> C-H-O-chains (green, wood, sugars) + O2

    - For animals and humans: C-H-O-chains (food) + O2 ---> CO2 + H2O + E (energy)

     

    CO2 and H2O are life-gasses, the source of all life on earth. This is what nature makes plants from, with energy from the sun.

     

    So, we humans live on sun energy, brought to us via plants, since we can not directly convert sunlight into meat bodies and into movement. Plant life, and human and animal life, are each half of the life cycle. Both formulas above are half of the life cycle, both equally necessary. They complement each other.

     

    Plastic is a very good product: it is made from oil and gas, and is formed into very clean and very usable products. After their usefull life, plastics can be burned cleanly (at least some of them, such as PLA, PE and PP, some burn less clean), and the resulting heat can be used to melt and form new products. If done well, there is no real waste. The "waste" gasses CO2 and H2O are not waste, but plant food. To make all deserts green again, we should produce more plastics, and burn more plastic, oil, coal and gass. More, not less. So, we in the 3D-printing community, are doing not too bad in saving life on earth.

     

    And of course, to save the earth, we should go driving in muscle cars with big fuel guzzling V8 engines, like in the '60s. Camaros, Corvettes, Firebirds, and Mustangs with 400HP. But now with good filters and catalysts on the exhaust. This is no joke, this is absolutely proven in true science.  :-)

     

    For some basic understanding, search the old documentaries: "The greening of planet Earth", and: "The greening of planet Earth continues". But there are lots of other valuable documentaries. Just stick to the proven science. What I say above is no secret, it is all very basic biology and biochemistry science, taught in high-school, between 15 and 18 years of age.

    Plastic is the future ..........but no need for fancy logo and carboard wrapping .....double wrap in plastic, label type of material on spool is fine....then UM......... it helps a little

    .....but the huge problem is with auto makers, boat engines and old diesel motors. And lets not forget airplanes, cruse ships, ferries, trains and the like....and electric cars at $100,000 does not help moving to new technology....
