They are also obviously advantaged for producing in the EU (if you’re in the US, 3M is thus even better as they produce in Kentucky). 3M products also get a further bonus thanks to their Pulp and Paper Sourcing Policy, explicitly asking since 2015 all 3M provider chain to respect not only the natural enviroment, but also the rights of workers, indigenous people and rural communities.Īn equivalent socially responsible policy is claimed by GlobalNotes, the German manufacturer for both Paperfoxx and Tesa. The only other brand with a recycled cardboard packaging, Stick’N, lost the associated points because said package also contained a glued sponge (!) used to lift up the notes from beneath. The 3M Recycled Post-it reaches a high score thanks to its 100% recycled paper and recycled cardboard packaging. Half a point for both recyclable packaging and guaranteed recyclability.1 point for carbon footprint: 0.75 for producing in the EU (if you’re on another continent, this should be awarded to producers in your vicinity) 0.25 for assessing lifecycle carbon footprint.Half a point for both sustainable adhesive sources and solvent-less glue.2.5 points for paper: recycled and FSC certified sustainable sources give points, the higher proportion the better.I researched each brand for its certifications and policies, and awarded points on the following elements: What kind of waste does one brainstorming session create? Experimental process The worse and longer it smells, the less points. If I don’t smell anything when I open the pack, I award 5. Smell indeed mostly comes from solvent, which means it can be a sign of harmful chemicals used in the adhesive that you’re going to put your hands on and let evaporate in your working space for days.īeyond the (admittedly limited) risk to health of small doses, an uncomfortable smell on pack opening is always a distraction to the group, and can induce headaches in the most sensitive participants. SmellĪ displeasing smell is not only a matter of comfort. I normalised these results on a 0 to 5 scale simply by linearly rating the price from most expensive (0) to least expensive (5). The median price is 0.02 €, and anything more expensive than 0.05 € a note is clearly a ripoff. I did not buy the few even more expensive products for this study, as they are too expensive to be considered in a professional usage anyway. Prices vary wildly from the cheapest Chinese product with notes worth less than a cent to the fanciest at a sixth of an euro a piece. I rated each model based on the following scale:ĭistribution of the prices of a single sticky note However, since days 20 and 30 had no difference in measured stickiness for models that were exposed that long, and since wall surface simply made it easier to spot glue failure without changing tendencies, it is sufficient to observe the wall at day 20. Since I received each model on a different date, I could not have 30 days of exposure for all of them. Put otherwise, either the glue is poor right from the start and for all surfaces, or it has good chances to stay for long. In a similar fashion, the window surface increases overall stickiness, but products fared comparably on both surfaces. It also appears that there is no perceivable change in stickiness between 20 days and 30 days. Even with a fan under the note for 5 minutes. I could measure no difference in falling tendencies. I just took all the sticky notes I could get my hands on! And then, I thought 8 wasn’t worth it to run one-month-long experiments, so I just hunted and bought all the standard size, acceptably priced stickies on Amazon France.Īnother hypothesis was that they went straight from pack to wall and the glue was more efficient this way, but I ran a parallel experiment over two hours trying to measure after how many sticking-unsticking cycles the glue would run out, and it turns out the limit is above 150.
