KEEP UP THE GOOD WORK!!!
Here is my shredder. It’s my own design, not to the PP drawings. I actually finished it over a year ago, but it took me this long to get round to making the video!
My compact shredder with aluminium frame. It need just some frame modifications, the hopper need to be laser cut in the next days.
I have made some modification, now the frame is perfecrt (last 3 pics) and I have change the blade setup.
I’m not a machine builder, still learning though. I’m an environmental engineer and I’m very interested to utilise precious plastic machines to tackle plastic waste problems, especially in remote areas where plastic recycling is not economically viable. I collaborate with Ramdhan and we created shredder and injection then we put it in Simeulue Island, Aceh, Indonesia. By the end of 2017 we also sent shredder and compression to Pomalaa, South East Sulawesi (I haven’t take the pic yet). Here are pics of the machines we built for Simeulue.
We have completed our Shredder/ Extruder unit after 2 years of testing and refining. Currently in the Pacific islands demonstrating the unit. Building our first 5 machines to be sent out by April, then the next 5 over 6-12 months. Happy to answer any questions, we aim to reach the remote and under-developed islands where waste management is a major issue.
Hello, we finished building the extrusion machine in Brasil!
Our website is: megatec.center
Our compressor & shredder is completed. Awaiting funding for injection and extrusion machine. Workspace is allocated and by middle July students will get stuck into collecting & organizing plastic waste, cleaning, recycling, creating and selling.
Made in Pakse, Laos
Was really awesome to build this machine and learn so much stuff, way beyond plastic alone.
Ats ame time see how much interest other people feel about the whole idea of what the waste could be, and becomes really visible the level of consumerism we live in. Amazing how creative people can be when they encounter something so trivial for some but unrealistic for others. This perspective only comes when and where people understand it, and that couldnt be possible without showing.
Good job everyone!
It’s Kate from Zero Waste YOLO Thailand, just finished building the new Shredder and wanna share it with you guys.
Any recommendation is most welcome.
Finished building the Extruder! She LIVES!
will be building another with controllable speed and working on a press to use alongside an oven.
Will post pictures when we get started on that.
Aaron & Will
Ready for testphase 1!
I actually think Dave’s V2.0 shredder is a very good balance of simplicity and performance, which is what you want for an open source anybody-can-build-it design. Of course you can always make improvements, but a lot of them are down to personal taste and wouldn’t suit everybody.
I built my shredder just to suit my own needs, not to propose it as a better version PP shredder. I think it would be less suitable as it’s more technical and contains some custom components that the average person would not be able to make/buy. Some of the ideas I’ve used people might like to incorporate into their own machines as add-ons to the basic design. I think the best way is to take something simple and adapt it to suit yourself using what resources you have available.
Switzerland is the game.
Two year ago i order the first lazer cut for shredder. With a lot of up and down, studies, arm broken etc… Today shredder still doesn’t work but i’m close to ! (It’s been 18 month i have this idea in my mind… Vidéo comming soon for the problem, i’m sur the solution will come from this forum !!!
But… i found a industrial shredder in a farm and i swapped it for an old motorcycle that i had.
Then i start to build the extrusion and after buying 2 mecanical motor really heavy i saw a post with an electric motor. I make a call at the distributor of Makita
for the after sales service to find out if they had it in a bin. Bingo they have one motor like i need and… Big suprise it’s a shredder for wood (Makita ud2500). It’s not over yet but some news next week if it’s work. (cost for a new one is 250 euro) and i have the PDF for electric shema. Feel free to ask if you need.
Winter is comming and like a lot of people here, it’s really cold in the workshop. So i strated to build injection.
Result in the topic Share your creation.
Totaly cost is not done and i leave in a fucking country where all is really expensive. Try to find the stuff in trash the most that i can.
Gruppo lame ✅
This is my injection machine, the frame is made from extruded aluminium, it is strong and lightweight, I am finishing it with a 3d printed hopper.
hi all. last week we started building the precious plastic machines (shredder, extrusion and injection molder) with a dozen art and design students. the injection molder is now working, the shredder and extrusion machines should be done next week. you can see our current status at: http://www.instagram.com/burg_halle or follow us at http://www.burg-halle.de/make for the next steps… best from germany! aart & team
Hello, we made modifications and redesigned the extruder.
We also ordered a industrial screw from China so the output of the machine is improved.
Here are some pics.
Next step is to make the machine more compact, so we are going to replace the motor and worm gear by smaller motor with same torque from China.
The price for this machine is US$2.000,00
Best Regards to all
We built a thing
Brasília – Brazil
Hand powered shreder and thermostat controlled injection machine.
High school students will be running the precious plastic machines.
power: 0.75kw at 20:1
machines: lathe & CNC/Mill, drill press, angle-grinder (3000e)
skills: advanced but not expert
materials : 300e for Motor/Reducer, 70 Speed Variator (VFD), 50 for the Chrome, 30 for the brass adapters, 100 for the heat bands, 15 for the small stuff, 20 for the aluminium, 5 for the drive shaft, 40 euros for electricity, 20 for PIDs & SSRs, 20 Euro for standard suppliers such ass grinding papers (lots), drills, …
in bazar : yes, see “catalonia connection”
This is great! We live in the Caribbean , here on Andros Island the amount of plastic is insane. We want to do a start up recycling business here. There is no recycling of any form here!
Awesome that you are taking initiative and able to do this!!
Please let me know if you are interested in The Bahamas!
Hello to You all there.
This is my own shredder wich I have in my heart 🙂
It is working really good.
Motor – 1.5kW
We are finished building our injection machine, ready to start testing lasercutted plexiglass molds! 🙂
Nice work! Great idea with the aluminum channel frame. That motor and worm-drive are nice an quiet.
@simeng do you mean that the shredder’s enclosure is not made out of steel? if that’s true then I don’t think there’s much you can do to solve your bending problem. The frame is meant to absorb a great amount of the shredding torque so wood or other non-ferric materials will hardly resist the forces generated when shredding
I built a shredder in International School of the Hague. It took me two years. The box and framework are not steel though, because we don’t have any equipment to work with metal in school. But it works! (Apart from 3mm thick acrylic, the screws which hold side blades are bent after shredding) Is there anyway to prevent the screws from bending?
I would love to see the double-axe design of andyn make it to the next version of the PP-Shredder. Very goog job. I still beleive though that the motor is too weak. Profressional small size shredders (feed-port-dimension 110mm x 180mm, so slightly bigger than the PP-Shredder) are powered with a 2.2kw motor. I would be mad if i put all that effort in building a shredder, which clogs with milkbottles. But then, the revverse-procedure is very intelligent.
