Broad terms like 'brick' aren't copyrighted. If you make one that happens to work well with it, it doesn't mean you copied them. There is nothing wrong with this so long as it isn't a 1 to 1 recreation of lego bricks. Now his bricks, through testing, have been shown to work 'well' with lego brand bricks. You can make any plastic toy brick so long as you dont follow the exact specifications that they used. It is not a lego brand brick, and toy plastic bricks themselves are not patented by lego. Now in this scenario he has made a connecting brick toy that people can print and use for their own purpose. If I don't pursue legal action the law doesn't give a shit what happens. But there is nothing legally forcing me to make you take the content down as it is my content. Unfortunately the definition with fair use is a debated topic. If I make OC John Writer the 3rd in a hit new game that I own I dont have to apply a DMC to your youtube channel for making a video based on the content.

There are plenty of companies that turn a blind eye to people using their characters, assests, etc because it is good pr. Also putting PLA into the plastic recycling bin can be could be potentially very harmful as well as it deteriorates the physical properties of the recycled plastic blend as it is nearly indistinguishable from PET during floating and density separations It’s another story for industrial composters but I doubt a single person even does that here. PLA doesn’t appear to decompose much faster than traditional plastics in nature.

Also PVC is most used in the building and construction sector (69%) so it‘ll likely not be substituted by PLA as its physical properties just aren’t suitable for these applications.Īlso „not easily biodegradable“ is somewhat of an understatement. Of all these only PVC contains halogenides to any significant amounts, special polymers like PTFE, PCTFE etc are negligible by mass of total plastic waste. The largest groups in nonfiber plastics production are Polyethylene (~36%), Polypropylene (21%), Polyvinyl chloride (12%) followed by Polyethylene terephtalate (PET), polyurethane (PU) and Polystyrene (PS) with <10% each. Non-reddit communities are listed in our getting started guideĪlso I wouldn’t say that „many“ plastics contain halogenides with a few exceptions.
