@cymek and I are working in the Precious Plastic & Parley shipping container in the Maldives til May.

While we’re here one of our focuses is learning about ocean plastic, particularly how the extended exposure to saltwater/UV/contamination affects its recyclability with the PP machines.

We’ll share our research below 🙂

@pauldufour @joandarcy @frogfall and everyone else on here, thank you so much for gathering all this information.  This is all encouraging and motivating.  I am working on starting a shop in the greater Seattle area just to handle some of the local plastic garbage.  But this information is really broadening my sights on what I can do to help in my area and how big of an issue this really is.

In regards to the fuming issue, has anyone looked into adding an exhaust setup to their machines?  Who does anyone know the proper amount of air exchanges needed to handle such fumes?

The V4 team is starting to look at the fume issue here https://davehakkens.nl/community/forums/topic/v4-fume-extraction-4/ . I added a fume hood to my version of an injection machine here https://davehakkens.nl/community/forums/topic/portable-desktop-injection-machine/page/3/ .

Depending on which machine you have or are planning to build, it can be easy or more difficult. Building it on wheels so you can roll it outside helps as well.

Perhaps out of scope yet but there is a new low-coast device for plastic type detection on the way (ordering in progress). PP could assist in MP sample – collection, for the Maldives, as a start; and at some point process it. Could be interesting though to know it where comes from and where it goes ( there is a pet project of mine in progress, MP tracker/sensor).

@a-mind-of-comfort we use an extraction hood for a large cooker that we bought off a restaurant that was closing down and we have fitted carbon filters to deal with VOCs.

For a fume hood, one option could be adapting one of the 4 tube fluorescent shop lights. A lot of shops are switching to LED lighting and you may be able to get one for free from Craigslist or ask an electrician. Maybe add a skirt, hook up a blower (example: https://www.harborfreight.com/3-speed-portable-blower-61729.html ) and some ducting, for around $100 you could have a start of a system.

By the way, since they ware having a sale this weekend, I picked up one of those blowers. For its size, it moves a lot of air. I’ll probably make some version of the hood I described.

There are a number of activities in other projects – publiclab DOT org/wiki/babylegs -, also searching for possibilities to recycle micro plastics. Would be great if you could collect some samples before coming home. Thanks.
