The amount of energy saved by recycling used goods versus manufacturing new ones is up for debate, but reducing the amount of waste that goes into landfills is not, and that's exactly what
Schwalbe aims to achieve with their used tire recycling pilot program. The development of the innovative feedstock system comes with help from Pyrum Innovations AG, a German-based company that specializes in building and operating plants to thermally decompose organic materials, and the Technische Hochschule Köln – University of Applied Sciences.
Supported by the German Federal Ministry for Economic Affairs and Energy (BMWi), the project is researching how to develop a sustainable recycling system for used bicycle tires. Currently, unwanted tires are incinerated or buried in landfills and the goal of the collaborating partners is to change this to a closed-loop economic system by recovering the raw materials. In particular, Schwalbe plans to take the secondary raw materials from the recycling process and put them towards brand new products.
As it stands, Schwalbe, states that all of the bicycles tubes they manufacture are 100% recyclable. They started a project back in 2015 to collect used tubes from dealers, recycling and reusing them to make tubes of equal quality. Schwalbe is continually becoming more sustainable and won the German Sustainability Award 2021 in the ‘Pioneers’ category.
We've reached out to Schwalbe to ask if their full intent is to build on this process and manufacture tubes and tires from 100% recycled rubber.
Pryum Innovations AG is an innovative recycling technology company based in Germany. On the basis of the worldwide patented, unique thermolysis process, the company develops, builds and operates recycling plants, with the help of which Pyrum extracts raw materials of high quality from used tires, rubber and plastic waste and feeds them back into the material cycle. The raw materials obtained include thermolysis oil, for which Pyrum has received REACH certification, and recovered carbon black (rCB).
Update:Schwalbe has now implemented its tube recycling initiative in Switzerland with the help of Zibatra Logistik AG, becoming the fifth country in the program to recover discarded tubes of any brand at any bicycle retailer. Almost six million tubes have been recycled since 2015 with Schwalbe's devulcanization process throughout Germany, Great Britain, Belgium and the Netherlands. The program is set to begin in North America in early 2022 with the tire recycling to follow suit as well, once logistics are in place.
Shops simply register for the program, collect old tubes, box and then ship the unwanted ones to Schwalbe free of charge. The process also won Schwalbe the Eurobike Green Award 2015, the Green Concept Award 2020 and the German Sustainability Award 2021.
When asked if Schwalbe's full intent is to build on this process and manufacture all tubes and tires from 100% recycled rubber in the future, their public relations manager, Steffen Jüngst, had this to say:
| Our current pilot project is testing a recycling system for End of Life (EoL)-bicycle tires that generates valuable secondary raw materials in terms of the circular economy. In the long term, we would like to establish the Schwalbe Recycling System as a sustainable alternative compared to the current disposal by means of waste incineration. Our research department is working hard on the use of recycled materials in new Schwalbe products. However, this development must comply with all safety-relevant properties of our products and ensure a certain performance. The use of secondary raw materials will therefore depend on technical, environmental and last but not least economical factors. |
Is there a major difference in energy consumed to recycle and then manufacture versus simply starting over though?
| All our sustainability activities are based on well-founded studies. With this in mind, we take a very close look at the overall process for Schwalbe's tire recycling approach. The ultimate goal is to reduce both energy and resource use.
As we currently are still in the status of a pilot project with our tires we can give you some data from our inner tube recycling program where we have been using material for new products since a while. There the production of the recycled material saves 80% energy and therefore also 80% CO2 compared to the production of the same amount of new material.— Schwalbe Public Relations Manager, Steffen Jüngst |
I recently watched a documentary about tires and near the beginning of the doc they asked "what is a product that is discarded when it is only 5% worn?" The answer is tires!
Not sure why you got downvoted for that, nobody can argue that is highly wasteful. Stupid if you ask me….
I don't know what Schwalbe is up to with recycled rubber but I really would like to know is it truly better for enviroment than using old rubber as sidewalk etc. I can't stop thinking that all enviromental issues are just to increase sells and make people fell better when buying new bike stuff.
where people run their tires down the cords,
because it never rains no mo
Turns out, it has a serious effect on the environment running them way past their wear marks:
www.washington.edu/news/2020/12/03/tire-related-chemical-largely-responsible-for-adult-coho-salmon-deaths-in-urban-streams
Guess I remembered wrong, been a bit since I read it.
Hopefully they can find a substitute for that chemical.
Funny how it took them so long because tire compounds are proprietary,
so they had to reverse engineer what chemicals were entering the waste stream.
There must be sooooo many cases of that, where "trade secrets" allow them to pollute like mad.
I dont have that problem with Michelin, Schwalbe or Onza, probably many more but MAXXIS even said it on their side that the high-quality rubber is not good for that and you should get dual ply
6°c is a joke to be honest.
@techride
One other negative point about Maxxis is that their tyres sometimes come twisted out of the box, OR, and that's also a big issue: they get and stay twisted after a big shock. If happened again lastly with my front DHF after a big compression. I was running something like 21psi, so nothing fancy.
I tried several times to remount it properly, no way: it's definitely twisted, and I don't speak about the rear tyre: a DHRII. It's so twisted that the wheel looks bent...
May be I'm just not lucky, but it never occurs with the Magic Mary or the Dirty Dan I use during autumn/winter.
Maybe it is time to start a recycling program that would involve the riders as well (not only bike shops). We already have this with our bottles and cans. I wouldn't mind giving back my old tires and get a discount on the new ones....
Unfortunately it is only a dream.....
Nothing is perfect, but at least to knobs stay on Maxxis and the beads stay on the rim.
MAXXIS in comparison with their DD isn't great in damping like the Super Gravity does it. Punctures are way more common with that DD in my book. With the Super Gravity I run for a year now, I dont even had ONE. I did switch back for MAXXIS for a week because blown bikeparts and testrides on other bikes. I had instant failures with those tires. I had the comparable Schwalbe carcasses also for way longer with even an SS thread and no puncture with it. Center slice on the MAXXIS with DHF and Assegai so na man..
I had run on the back BB, till I could no longer brake with it and the cuts only then appeared and they said, "f*ck you, ride better lines" The tire "said f*ck that, I dont give up even without center knobs". Yeah I have used it till there was not that much left. Consistent till the end, the SG and the ADDIX Soft will be a bit above average tire wear. The worst tire I had for radical wear was the OLD stuff from Schwalbe or the Michelin Wild Enduros.
I like to try new stuff, so maybe I get some Vitorias or whatever next year. If I dont like it I sell it and thats it.
You cant talk about equipment if you never have had some other crap below yourself.
GMBN riders seem to like them very much. I'd like to have more feedbacks about these.........
I'm fed up with Maxxis and don't want to put my money in their gums anymore. I love Schwalbies, but their last versions are on the heavy side (1220g for a 2.40" Super Trail MM, come on!!!)
I used to love Onza tyres, but their range of products is too narrow, like Hutchinson BTW, and I don't need tons of references but 2 or 3 tyres max to cover the 4 seasons of the year.
Also, if I find the perfect tyres, my evenings are gonna be boring
Yeah Schwalbe is super heavy, SuperGravity BigBetty 29"x2.6" is 1,45kg. I pedal this half a day, no problem if I wont get any flat, I don't care. My bike weight is maybe 17kg, dont care also. You dont talk about weight in the Privateer club
Like I said also above the SG tires damping is incredible. Its free suspension performance, hehe.
Onza would be the winner if they have actual tires for 30mm rims. They still make the narrow stuff for racing I guess?
Don't know what my choice for most overrated product would be. Water bottles? Avid brakes? Never had an issue with the actual performance of the older Maxxis tyres that I sometimes used, but yeah they lasted no time at all and I wouldn't buy any new ones for the price they charge!
On 27,5" I had almost zero problems with Maxxis DH HighRoller or DHR II both 60a, dual ply. Now on 29" I haven't found as reliable tire as previous two were on 27,5". Any recomendation for rear tire - I only want as much puncture protection as possible and hard compound (I don't want to pedal super tracky tires on the uphils)?
I also doubt that there are no other compounds gripping like that. I would say Onza with their GRP 40.
I have stopped riding super soft stuff this year because the "soft" BB super gravity tire's did hold up till October and it's actually not that difficult to ride. Traveling is still off for me so I won't have that big challenges because the twats also destroyed most of the good trail's we had.
Will try ultra soft for the front if I can get it.

I bought it a year ago and they had some sale going on so I got the ugly red colour. Worth it to monitor them and wait for a deal or reach out and see what they will offer you.
So many of these things are greenwashing... This is not.
Now Schwalbe, can you make a Magic Mary at under 1000g again please?
As a bike mechanic, I know for years that bicycle tyres are absolutely not recycled nor optimized like car or truck tyres which are mostly grinded and used for roads and buildings constructions, for instance.
I hate to do that, but every working day I throw some used tyres that I put in the normal bin, because despite of my will I don't have any other solution. The public dump refuse them, and the contacted authorities have no answer to the question. I hate that.
Dont say anything about MAXXIS because that is not a f*cking tire for even the autumn if I want 3C.
Maybe I did misread it yeh, non the less how this could make it more expensive is still a big question to me.
So what are you rocking?
I am only pointing out what industry and mass manufacturers are looking at.
Shame the technology isnt quite there for IVD's yet!
Just made that up of course as this is Pinkbike and I don't work in medical devices R&D for the world leader in a sector.
