New Year, New Spool

While 3D printing has the potential to decentralize product design and manufacturing, nothing is without it’s drawbacks. One of the biggest for 3D printing is the inherent waste of filament packaging. Filament typically comes vacuum-sealed on a plastic spool with a tiny silica gel packet. The plastic film and silica gel are there to prevent water uptake which can have a negative impact on filament performance, and the spool is there to provide the filament with structure and an easy way to keep the long strand of plastic from tangling.

The problem comes when you reach the end of the spool. What are you supposed to do with an empty spool? People on Thingiverse and the other 3D printer file repositories have come up with an impressive number of solutions to reusing these empty spools, but at some point, enough is enough. Luckily, makers are an inventive bunch, and RichRap came up with a solution called the Master Spool.

By making the spool a reusable part of the 3D printing process, filament is cheaper to ship with a reduced weight and carbon footprint. Since it’s an open standard, any filament manufacturer can jump onboard and offer their filament as Maker Spool refills. Master Spool is still new enough that only a few manufacturers are supporting it so far, but the speed of adoptions makes me think this will become the new normal for 3D printer filaments.

I ordered my Master Spools from Filastruder, and so far, I’m really impressed by the quality of the filament and how simple it was to put the Master Spool together. Two bolts and cutting three zip ties is all it takes to free yourself from an unending pile of empty filament spools.

This system isn’t entirely without waste, but it’s a big improvement over what came before. The plastic film can probably be recycled with other plastic bags in your area (usually at grocery stores), but I’m not sure what to do with the zip ties other than throw them in the trash. I keep the silica gel and put it in with my filament to try keeping it dry, but if I were a manufacturer, I’d spend the little bit extra and spring for the reusable silica gel packets with color indicator to reduce waste even more.

I think this is still a win for making 3D printing more sustainable. What do you think? Let us know in the comments!

Recycling Rant – Mixed Materials

I know that recycling shouldn’t be our first line of defense to handle our waste streams, but it is something that can help divert materials from the landfill once they already have been created. But you wanna know what really grinds my gears? Mixed material food packaging. Sure, China’s National Sword cut a great big hole through US recycling efforts, but we can still recycle #1 and #2 plastics in most municipalities, and #5 if there’s a Whole Foods somewhere in your area.

If we want to encourage recycling though, we need it to be easy. People are busy, making their waste stream pretty low on their priority list. So, why on Earth would you make a dairy container out of #5 plastic and put a #2 lid on it? You took the time to make sure the two plastics looked identical for cohesive branding, but the only visual difference to the consumer is if they look at the little recycle triangle on BOTH parts of the package. Is this easy? NO! Store bought icing is even worse with its #5 or #2 body and #4 lid. Where the heck am I supposed to recycle a #4 that isn’t a plastic film like a bread bag?

As engineers, I know we want to find the optimal solution for every component of a design, but for single-use containers, end-of-life needs to be high on that priority list. I’m not a food packaging engineer, but my hierarchy of design would go something like safety/preservation of food, taste impact, mechanical stability, and end-of-life. I’ll grant you that you can’t package in something that will impact taste or safety, but is that #2 lid really making enough of a difference in your product that it’s worth confusing people so you get #2 and #5 plastics mixed up in each other waste streams?

If you ARE a food packaging engineer, I’m begging you to please consider end of life when designing your products. We are on a finite planet, and because plastic is such a useful material, I would really love it if we could easily reclaim it for future use. Whether it’s particularly safe for contact with food or whether we really need so much of it is a whole ‘nother ball of wax. For today, please think through your material choices and try to find ways to make recycling easier.

Moving toward a zero waste, solarpunk, circular economy is high on my wish list for the world, and there’s plenty of research that shows that unless you make something easier than the alternative, people just don’t have the bandwidth. The onus is on the designer, not the consumer for this. We can do better – please do!

Tidalpunk, logistics, and degrowth

Grist recently ran an article about a Costa Rican project to build a carbon neutral shipping fleet using traditional wooden boat building techniques including sails as the primary means of propulsion. Maria Gallucci writes that the worldwide commercial shipping industry moves 10.7 billion tonnes of material every year, predominantly by diesel powered megaships.

This seems particularly problematic when we look at the 262 million tonnes of municipal waste generated in the US alone every year. The article about the Costa Rican fleet said sailing vessels wouldn’t be able to make up a large proportion of the shipping fleet, but the question I had was, “Do we really need to be shipping this much stuff?”

While capitalism is based on unending, cancerous growth, there is a growing community of people around the world investigating how dialing back the economy could be better for people and the planet. When coupled with a circular economy, the degrowth movement points toward a brighter, greener future like that envisioned in solarpunk. Decentralized, local production of goods using recycled technical and biological nutrients would lead to a more resilient and less energy-intensive supply chain.

Some front-line communities are already leading the charge against climate change by developing solutions that are much more relevant to their local environment than the one-size-fits-all techno-solutionism often argued for in the US and other western countries.

What do you think? Should we just find “sustainable” ways to keep consumption at it’s current levels, or should we reevaluate our relationships with material goods? Let us know below!

Urban Ore – What the future of Zero Waste looks like


The Institute for Local Self Reliance podcast recently chatted with the founders of Urban Ore in Berkley about how they divert waste from the landfill and are able to make a living from the old adage: “One man’s trash is another man’s treasure.”

While a lot of what Urban Ore sells is architectural salvage, they also have clothing, books, sporting goods, and many other items. Urban Ore mostly gets their salvage from the municipal waste stream in Berkley, so it’s an interesting case study in better ways to manage garbage in an urban environment. It makes a true Zero Waste future not seem so crazy after all for us solarpunks.

Urban Ore also has a really interesting employment compensation structure where everyone, including the owners, gets an hourly wage. The base wage depends on the job employee does, but they make more on top of that based on sales pro-rated to how much they were working that week. No specific commissions are given, just a profit sharing bonus tabulated each week. I think this is a good company to look at for ways to plan equitable compensation for solarpunk jobs.

KitchenMade Measuring Cups Review

2018-02-07-17-26-43_origSolarpunk living includes a pretty strong waste reduction component as part of being environmentally conscientious. One of the simpler ways to reduce the amount of waste you generate is to cook your own food. While the greenest measuring cups are the ones you already have, if you are in need of a set, the KitchenMade Stainless Steel 6 Piece Stackable Set is the best I’ve come across. The measuring cups are each made from just one piece of stainless steel, so they are easy to clean and could be recycled if needed. Short of being hit by a truck, I don’t see how they would break and need recycling though.


Besides their indestructibility, the best feature is the little indents on the sides for smaller measurements. For instance, the 1 cup also has gradations for 1/2 and 3/4 cups. This is great when you’ve been cooking a lot (Thanksgiving, anyone?) and your 1/2 cup is already dirty. The little gradations aren’t deep enough to trap anything from getting cleaned, and I usually just throw mine in the dishwasher. The only real downside to these measuring cups is that the labels for the gradations are written from the outside. Since the labels are stamped into the metal, you can see them from the inside, but you’ll need to read backward to know what the measurement is.

At the time of writing, the KitchenMade Stainless Steel 6 Piece Stackable Set is $23. There is also a combo of the KitchenMade measuring cups and measuring spoons available for $30.
