Recycling sprue and box waste?
Posted by SilenceDeuxgood on Sunday, May 27, 2018 10:44 PM

While I'm not entirely environmentally conscious, I tend to notice after ever couple builds i seen to have a stack of empty sprues that I usually end up throwing away. Are there any model companies that have a recycling program? based on the number of you guys on here, Seems like a lot of styrene waste that could be melted down and made into more kits... Perhaps one of them could start a reward program? For every pound of styrene recycled, you get a kit!

I just recycle it like everything else. All the kits are made overeas, I would assume that it would cost far more than it's worth to deal with the old sprues and that is a companies care about. But a nice idea from an environment standpoint.

Yeah, same here. Into the recycle bin. Although, right now I'm hanging on to sprue. I have a freezer bag about half full of the stuff. There is a fellow in our IPMS group who uses sprue and I may pass my bag off to him.

OK. On the bench:

Mostly into the recycle, although I do save the smaller optional bits that I don't use. Like small diameter round and flat bits, they can be useful at times, and some sprue runs that can be used for melting into stretched, longer bits.

And I usually find lots of thin flat parts that are useful for shimming to fill gaps, that makes for a stronger join than using filler. The little sprue tags for the part number can also serve a purpose.

Did Someone mention Sprue ?

 Gee , sure collects fast when you build a lot . Now then , I turn it into different colors of filler . Some is real thick and some runs like tube glue ! It also works like piping in Refinery and Tanker deck hardware .

  It's great for exhaust systems on Cars , Trucks and Armor . In Cars and Trucks it's great for roll cages and stuff too . I have even shaped it into ship and boat Frames and Keels .

I recycle spruces into stir sticks for paint. Other uses stretch sprees for wiring of sorts.

I keep a shoe box full of various colors of sprue for all of the above uses and the rest goes into the recycle with the household stuff.

Well I may have gone a bit overboard with regards to sprue.

I had a chance to pick up a very simple injection molding machine a few yeras back.  One of my retirement projects is to get this up and running along with researching making simple molds for it to use. I may not get into the big steel molds etc. but using the lost wax process make a few bronze molds for simple quick limited runs. Maybe some of the industrial resins to make limited runs mold that may stand up to the process.

Have to occupy my retirement time some way.

So I have been collecting all my sprue and that with the plan to re-use it.

I don't know if I will ever get to it, but at least that is the plan.

Yes, I know a modeler who uses sprues as his raw material to sculpt figures.  He warms the sprue in an old pan till he can form it into a rough shape and then he carves this, just as one might use putty.  I save up my sprues till I have a freezer-bag-full, and then send it to him.

As for boxes, they can just go in the recycling, too, though I save mine, for now, for the box art.

Best regards,

I'll save longer, straight sprue parts for paint stirrers or future use as stretched antennas. Others go into my plastics recyclable bin. Cardboard goes into a cardboard recycle bin.
