reTyre claims its rubber-free tires are 100% recyclable – and
longer-lasting

By Ben Coxworth
June 30, 2023

Because they're made of vulcanized rubber, old tires can't simply
be melted down and used to make new tires. Such is reportedly not
the case, however, with new rubber-free tires made from
eco-friendly elastomers.

Although conventional tires can be recycled, they're typically
ground into rubber crumbs that are utilized in materials such as
asphalt. Since the vulcanization process is not reversible, using
them in the production of new tires generally isn't an option.

That's where Norwegian company reTyre comes in.

It has started making tires out of proprietary bio-based TPEs
(thermoplastic elastomers), which are claimed to be 100%
recyclable. In other words, entire tires made from the material –
including both the casing and the beads – can be recycled into
more tires.

Total manufacturing costs are said to be comparable to those of
rubber tires, as the company's "advanced production technology"
allows the tires to be produced at relatively small regional
factories as opposed to larger far-away plants. This should
result in much lower shipping-related CO2 emissions, and lower
shipping costs. What's more, the production process is claimed to
use up to 90% less energy.

"Generally speaking, TPEs are a little pricier than rubber,"
reTyre brand designer Friedemann Ohse told us. "But since our
machines are small and our tires will be locally produced, it
will save companies a lot of time and money due to short supply
chains (freight costs) and reduced waiting time."

Importantly, Ohse also stated that the material lasts longer than
rubber, and has better abrasion resistance.

reTyre is now seeking industry partners who may be interested in
utilizing the technology in the production of their own tires.

From AFP via Radio France International:


Final Ariane 5 blasts off amid Europe rocket crisis

July 6, 2023

Paris (AFP) – Europe's workhorse Ariane 5 rocket blasted off for
a final time on July 5, with its farewell flight after 27 years
of launches coming at a difficult time for European space
efforts.

Faced with soaring global competition, the continent has
unexpectedly found itself without a way to independently launch
heavy missions into space due to delays to the next-generation
Ariane 6 and Russia withdrawing its rockets.

The launch had been postponed twice. It was originally scheduled
on June 16, but was called off because of problems with
pyrotechnical lines in the rocket's booster, which have since
been replaced.

Another launch planned for July 4 was delayed by a day due to bad
weather.

The final payload on an Ariane 5 is a French military
communications satellite and a German communications satellite.

Marie-Anne Clair, the director of the Guiana Space Centre, told
AFP that the final flight of an Ariane 5, whose launches have
punctuated life in Kourou for nearly three decades, was "charged
with emotion" for the teams there.

Though it would become a reliable rocket, Ariane 5 had a rocky
start. Its maiden flight exploded moments after liftoff in 1996.
Its only other such failure came in 2002.

Herve Gilibert, an engineer who was working on Ariane 5 at the
time, said the 2002 explosion was a "traumatic experience" that
"left a deep impression on us".

But the rocket would embark on what was ultimately a long string
of successful launches.

The initial stumbles had "the positive effect of keeping us
absolutely vigilant," Gilibert said.

Webb and Juice

Ariane 5 earned such a reputation for reliability that NASA
trusted it to launch the $10 billion James Webb Space Telescope
in late 2021.

The rocket's second-last launch was in April this year, blasting
the European Space Agency's Juice spacecraft on its way to find
out whether Jupiter's icy moons can host alien life.

Daniel Neuenschwander, the ESA's head of space transportation,
said that in commercial terms, Ariane 5 had been "the spearhead
of Europe's space activities".

The rocket was able to carry a far bigger load than its
predecessor Ariane 4, giving Europe a competitive advantage and
allowing the continent to establish itself in the communication
satellite market.

While waiting for Ariane 6, whose first launch was initially
scheduled for 2020, Europe had been relying on Russia's Soyuz
rockets to get heavy-load missions into space.

But Russia withdrew space cooperation with Europe in response to
sanctions imposed over Moscow's invasion of Ukraine in February
2022.

The number of launches from Kourou fell from 15 in 2021 to six
last year.

Another blow came in December, when the first commercial flight
of the next-generation Vega C light launcher failed. Last week,
another problem was detected in the Vega C's engine, likely
pushing its return further into the future.

- 'Difficult times' -

The launcher market has been increasingly dominated by
billionaire Elon Musk's US firm SpaceX, whose rockets are now
blasting off once a week.

Lacking other options, the ESA was forced to turn to rival
SpaceX's Falcon 9 for the successful launch of its Euclid space
telescope on Saturday.

The ESA will also use a SpaceX rocket to launch satellites for
the EarthCARE observation mission.

It remains unclear how the agency will launch the next round of
satellites for the European Union's Galileo global navigation
system.

At the Paris Air Show earlier this month, ESA chief Josef
Aschbacher acknowledged that these were "difficult times," adding
that everyone was "working intensely" to get Ariane 6 and Vega-C
ready.

Ariane 6 was unveiled on a launch pad in Kourou earlier this
month ahead of an ignition test of its Vulcain 2.1 rocket engine.

Because the new rocket requires less staffing and maintenance,
190 out of 1,600 positions are being cut at the Kourou spaceport.
