TRI TAKES OVER SOEX UK
UK firm Textile
UK from its
The deal is
meant to boost
capacity and the
number of collection points it has across the coun-
try. At the moment, TRI collects, sorts and redis-
tributes more than 400 million garments annually.
The recycler says it is passionate about avoiding
waste and ensuring used textiles are woven back
into the circular economy.
‘We are delighted to welcome Andy Haws and our
new Soex colleagues to the group,’ comments TRI
ceo Mark Burrows-Smith. ‘Soex are a well-estab-
lished and respected operator in the used clothing
sector. We look forward to integrating the busi-
nesses and further developing a number of Soex’s
Meanwhile, TRI estimates that about 70% of the
world’s population wears reused clothing.
Recycling still has a way to go seeing as some 350
000 tonnes of used clothing enters UK landfills
In a bid to accelerate change, TRI is backing the
Textiles 2030 effort launched by sustainability char-
ity WRAP. The recycler is hopeful this ‘ground-
breaking, expert-led initiative’ will harness the
knowledge of UK leaders, thus helping the nation’s
fashion and textiles industry move towards circular-
SABIC TRUMPETS REPOLYMERISATION OF PET INTO
Chemical giant Sabic has
unveiled a polybutylene
terephthalate (PBT) resin
made from ocean-bound
ate (PET) bottles.
The company says its LNP
Elcrin WF0061BiQ resin is a
candidate for consumer
such as fan housings in
computers and automotive seating, as well as electrical connectors and enclo-
The new grade is the latest addition to Sabic’s portfolio of chemically recycled
materials which help support circularity while serving as potential drop-in
replacements for virgin PBT resins. However, industry observers note that PET
bottles are capable of mechanical recycling back into new bottles without that
extra energy required for chemical recycling.
‘We’re continually expanding our LNP Elcrin iQ portfolio – and the PET waste
streams used to produce these materials – to help divert more plastic from the
oceans while helping our customers incorporate recycled materials in their prod-
ucts, achieve their carbon neutrality goals and meet consumer demands for
greater sustainability,’ says Sabic’s Sanjay Mishra.
‘Within the next decade, we anticipate upcycling 10 billion plastic bottles into
higher-performing, durable materials that deliver enhanced value to customers.
Sabic is committed to working with the plastics supply chain to find new solu-
tions to address urgent environmental issues such as reducing ocean-bound
plastic waste and achieving net zero carbon emissions.’
SABIC’s proprietary technology, which involves the repolymerisation of ocean-
bound PET into PBT, delivers virgin-like performance properties. It says the pro-
cess surpasses mechanical recycling in quality and consistency.
‘According to an internal life cycle analysis conducted in accordance with ISO
14040/14044 protocols, LNP Elcrin WF0061BiQ compound can offer potential
reductions of up to 14% in carbon footprint and up to 25% in cumulative energy
demand, when compared to the virgin PBT compound reinforced with glass
fibre,’ adds Darpan Parikh, Americas customer fulfilment leader, specialties,
‘By replacing virgin material with our resins, customers can help reduce environ-
mental impacts by reusing plastic waste and eliminating halogenated additives.’

3D-PRINTING ROOMS OF THE FUTURE WITH
Researchers from Nanyang Technological University (NTU) in
Singapore have found a way to use recycled glass in
3D-printing. This breakthrough could make the building and
construction sector more sustainable.
Less than 15% of the 74 000 tonnes of glass waste generated in
Singapore was recycled in 2021 with most of the rest incinerat-
ed or landfilled. While glass has been used in concrete mixes,
NTU’s research is the first to successfully 3D-print a structure
using a glass-based concrete mixture.
The new process uses a specially formulated concrete mix of
recycled glass, commercial cement products, water and addi-
tives to 3D-print a concrete bench. Using an optimal formula-
tion, the NTU research team made a 40cm tall L-shaped bench
as a proof of concept that their material could be printed into
an everyday weight-bearing product.
In lab compression and filament quality (strength) tests, the
structure showed ‘excellent buildability’, meaning the concrete
does not deform or collapse before curing.The mix was fluid
enough to flow through the hoses and print nozzle.
‘The main challenge in formulating 3D-printable concrete mix-
tures is to figure out just how much of each component to add
to obtain a structurally sound structure with minimal defects,’
says project lead Professor Tan Ming Jen. ‘Our team has come
up with a feasible formula, demonstrating for the first time that
glass can indeed be used to 3D-print a bench with excellent
‘Around 70% of glass is made up of silicon dioxide, or silica.
What our research does is to essentially return the silica found
in glass to be reused again as sand in our 3D-printing concrete
As a result of the proof-of-concept, the NTU team believes the
development offers a ‘new pathway’ to recycling glass waste
and offers a greener building and construction material in line
with the circular economy.
The new development builds on previous 3D-printing for con-
struction research. The researchers were able to print the floor
and walls of a bathroom in 12 hours, half the time required for
As a next step, the researchers will collaborate with Singapore
start-up company Soda Lemon on larger and more diverse
structures using the recycled glass concrete mix. They also plan
to optimise the printing algorithm for consistent performance.
