September 2019
This month is big sheet press update. We revisited the large sheet press and changed the dimensions, now it’s capacity is 1,1m X 1,1m with 8T load. Made the first “Dry fit” for the press.
Made a really heavy duty pressing platform. Made use of old metal tubes ~4mm, cut them so that they can fit on the corner of the base of sheet press. Drilled a lot of 17mm holes and used old car screws for assembly.
Then we had a huuuge plastic ball delivery about 20 bags full of them.
Besides Precious Plastic work, we tried out pyrolysis with a large metal tube. It can fit about 2,500cm3 of waste non-recyclable plastic, it’s trown in the central heating system and it has a potential of being a source of heat. But it should be heated in no oxygen environment, so the tube should be filled with co2.
Working on 2 projects now.
1. One of which we are working with Illy recycable coffee pods.
For this we are working on a tool to cut the plastic pods open and compost the used coffee. But the problem with these pods is that, they have a paper filter, that is glued on the one end.
We have an idea to solve this problem – we will cut open the pods, take out the coffee and shred the plastic and then wash the shredded material to get rid of the paper filter.
2. Recycled plastic flower pots as a request. We had a lazercut mould for this job.
We didn’t have a lot of luck, the plastic stucked in the mould. And when using the mini cold press, it didn’t press enough the plastic to flow through the mould. Then the press exploded, well at least the pressing mechanism popped out of place. But now we know the process. The flower pot will be about 480g.
We made progress with the leg-powered shredder. We have progress. It works! Sort of… We need to work on the chain tension.
We upgraded our mini cold press. Making it bigger and now it has a working hight of 50cm and has a 2T hydraulic car jack.
