Bacteria recruited to build endlessly recyclable plastic

By Michael Irving
July 31, 2023

Plastic is one of the most useful materials in our modern world,
but unfortunately it's also one of the worst in a sustainability
sense. Now, scientists at Berkeley Lab have developed a way to
engineer bacteria to produce raw materials that can be made into
plastics that are completely recyclable.

Plastic recycling programs mean well, but the disappointing truth
is that the vast majority is incinerated or ends up in landfill.
In 2019, Berkeley Lab unveiled a new type of plastic called
polydiketoenamine (PDK), in which the bonds between the molecules
can be broken down more easily on demand, ready to be made into
something new with no loss of quality.

In previous studies, the scientists initially made PDK out of the
same petrochemicals that go into regular plastic, but for the new
study they've successfully switched to a renewable source
instead. The team engineered E. coli so that it could convert
sugars from plants into a molecule called triacetic acid lactone
(TAL), which can then be combined with other chemicals to produce
PDK.

The end result is a plastic material that can be selectively
tuned to be flexible, tough or even adhesive, depending on the
application at hand. Not only is this new PDK more sustainable,
but the team found that it can also handle hotter working
temperatures than the earlier version – up to 60 °C (140 °F).
This opens up a wider range of potential applications.

In its current form, the PDK is made up of around 80%
bio-content, but the team says that future versions will shoot
for 100%. Other improvements that will be the focus of more work
include finding ways to get bacteria to convert a wider range of
plant sugars and compounds into the raw materials, and speeding
up that conversion.

"Our new results are extremely encouraging," said Corinne Scown,
an author of the study. "We found that with even modest
improvements to the production process, we could soon be making
bio-based PDK plastics that are both cheaper and emit less CO2
than those made with fossil fuels."

The research was published in the journal Nature Sustainability.

From New Atlas:

Blue Alchemist to make solar cells on the Moon using moondust

By David Szondy
July 27, 2023

With the aim of allowing astronauts to live off the land as much
as possible when they return to the Moon, NASA has awarded Blue
Origin a US$35-million Tipping Point contract to develop the
company's Blue Alchemist process to make solar cells out of lunar
soil.

The biggest bottleneck to establishing a permanent human presence
on the Moon and beyond is the staggering cost of sending
equipment and supplies from Earth. NASA and other space agencies
believe that the best way to overcome this is to use local
resources as much as possible to manufacture what's needed.

Under development since 2021, Blue Alchemist is an example of
this. The basic concept is to develop a complete process that
takes the lunar soil, more formally known as the regolith, at one
end and spits out complete solar cells and other products at the
other.

Using a simulated lunar regolith raw material created on Earth
that mimics the grain size as well as the elements in the
original, Blue Alchemist uses a series of steps to melt the
material at 1,600 °C (2.912 °F) and then remove the various
elements using electrolysis and other methods, with a contactless
system moving the molten material from one stage to the next. All
of these can be replicated under lunar conditions.

Through the process, oxygen is boiled off and collected. Metals
are then extracted, including iron, aluminum, and silicon. The
end product is silicon that is more than 99.999% pure, suitable
for solar cells, and does not need toxic or explosive methods to
produce. Even the glass used to coat the cells made from the
silicon is a product of Blue Alchemist. According to Blue Origin,
this, along with being emission-free, also makes it a more
environmentally friendly system for use on Earth.

"Harnessing the vast resources in space to benefit Earth is part
of our mission, and we're inspired and humbled to receive this
investment from NASA to advance our innovation," said Pat Remias,
vice president, Capabilities Directorate of Space Systems
Development. "First we return humans to the Moon, then we start
to 'live off the land.'"

The contract is aimed at an autonomous demonstration of Blue
Alchemist by 2026.
