You take a bottle and shove small pieces of trash in it until it’s full and heavy. The ideal solution is you donate them and they’re used to make small schools and such in more underdeveloped areas. But it also helps reduce the amount of small pieces of trash that get in the ocean cause now they’re locked away in a plastic bottle
its in the name “eco brick” the objective is to pack the hard plastic so full of the smaller plastics to the point where theres no air left and its hard as brick. they cut the hard plastic off at the end and u are left with your “eco brick” make enough and youll have enough to build something out it. this is why its important when making to be sure that theres no bacteria or water packed in with the garbage or over time it will implode/explode
so yeah building off what 2 said, use any hard sided container (ex: the full one was a cranberry juice gallon, the new one was a starbucks coffee container) and you must rinse them out and dry them completely before filling. remove the packaging and cut that up into very small pieces and simply put them into the container. then continue this process with any and all big and small plastic (wrappers, RECEIPTS, plastic tags from new clothes, etc.) and cut them very small. always let them dry off
fully if wet. if they’re trapped in the container with moisture and sit in the heat it’ll ruin the container and there’s a whole science involved. the smaller you cut, the better, cause the more you can fit inside. i certainly did not do that for my first one so i’m trying to do better going forward. but the purpose of this is so that those small plastic wrappers and packaging will shape and mold to its container, so by the time the container breaks down, the plastic will essentially act like a
brick and break down as one, which reduces the amount of small plastic that may potentially find its way to a water source. and like 2 said, you can donate them to cities and schools to use for construction, as the stack these bricks together to form stairs and buildings combined with cement or other similar material to solidify the structures!
you can make alot of things, id recommend keeping it and creating something urself theirs plenty of inspo online. it honestly yakes so long to fill even one up compactly the correct way. you can also donate them to schools that have eco brick programs. im gonna copy and paste what this dude in my subreddit group said bc i think he put it well. bc these things shouldnt rlly be recycled or thrown out especially bc u probably wont make it correctly and it does have a high chance of exploding (1/2)
i didnt realize i cant copy and paste but the gist of it is the point of eco bricks is to turn plastic waste into something sustainable and reusable. if your gonna send it to the land fill or the recycling plant anyway its best to leave it loose bc its makes harder for the people and the machines.
honestly yea an unfortunate downside. it can be used for alot of indoor structures, or for filling. outdoor structures its usually covered in something like cobb or like some kinda earthen substance. it’s honestly a short term solution. like anything. because eventually we’ll all be dead and itll all end up trash somewhere. (so sorry if thats bleak)
