Hey dude – I know this post is old, but I’ll share a couple resources I recently came across since I’m also investigating the same topic.
Search for the following articles:
“Utilization of PET Waste in Plastic Bricks, Flexible Pavement & asAlternative Constructional Material – A review” by Abhishek Chhazed
“Exploring the Current Practices of PostConsumer PET Bottles and the InnovativeApplications as a Sustainable BuildingMaterial – A Way Ahead” by Arulmalar Ramaraj
“Innovative and Sustainable Application ofPET Bottle a Green Construction Overview” by Himanshu Sharma
Also the organization Fundacion Ecoinclusion in Cordoba, Argentina has creating a good looking program.
I second that question: has anyone been successful in using PP machines to make a product from PET? Any experiments happening out there? What have your results been so far?
@cgoflyn2 thanks for your input and glad to hear V4 is working on compiling a list of these things. It seems like most of the machinery you listed is for for post production finishing (except maybe the welder)? Is that a correct assumption?
Any other recommendations for tools/gadgets for machine maintenance? Collecting? Cleaning? Processing?
Thank you for sharing erikgoksoyr ! Really helpful to have the step-by-step experimentation process communicated in such a detailed manner. Much appreciated.
One question: In the material/compression investigation you make note a few times about the strength and durability of the end product. How did you go about testing strength? Was it just by feel?
Hey upcycletaranakinz ! I am also investigating this question – I will be doing a waste/plastic audit for some beaches in Mexico later this month. I found some tool kits created by BreakFreeFromPlastic.org that were helpful. Although they mainly focus on “Brand Auditing” the diagrams they’ve put together seem useful.
Here are a few links:
Typically certain types of items are made from certain types of plastic (e.g. food containers usually from #5, rubbery items typically are PVC) and thus sometimes assumptions can be made by categorizing objects.
One question I’m also looking to answer is how to identify plastic types from objects that are no longer in their original form. I will try to utilize some techniques that were outlined by PP here in this video: https://www.youtube.com/watch?v=fsqLJNyrVss
Let us know if you’ve learned any new techniques from your beach clean ups! I’m sure there are many people curious to know.
@frogfall, Thanks for your lengthy opinion. Do you like your coffee black?
There are still some suitable applications for reusable plastic cups, not necessarily just coffee. One use I’m particularly interested in is for large events/festivals where the bars & food vendors offer plastic cups that are circulated, cleaned, reused throughout the event. Plastic is a great option because it does not break when dropped (party proof) & is less expensive than stainless steel.
A few recommendations gleaned from the USFDA article:
– Select your feedstock carefully. Using already food-grade PP#5 is a good choice. They make baby bottles from PP#5, so it should be safe, right? Avoid containers that held cleaners, pesticides, automotive chemicals, etc.
– Clean feedstock thoroughly. Cleaning shredded plastic increases surface area available to be cleaned.
-Your workspace should be as clean as a “commercially certified kitchen.” Sterilized machines & surfaces, rodent-free, etc.
Following 🙂 Also interested in producing reusable cups & plates for events.
Hey Verenal, beautiful stuff! Can you say a little bit more about the product in the last picture? Combined plastic & leather canister?
Add me to this list of interested people! In addition to bricks, I’d like to explore other construction materials.
Hey everyone, thanks for the discussion.
Wondering if anyone is willing to share an itemized budget for a workshop start-up costs? I understand the costs of many items vary dramatically based on locale, but I am trying to get a comprehensive idea on what all is needed to get a workshop up & running. There are lots of comments throughout the forum of how much a machine build is, but not too much info on how one gets to that total cost. I’m looking for some detail!
Thanks all! If you’re willing to share, please DM & I can provide my direct email.
aloja grisel! que bueno saber que ya has comenzado rockear! tengo planes comenzar algo en tulum y me encantaria colaborar. te voy a mandar un correo directamente . saludos!
