Tupperware expands ECO+ line
Nova has introduced three grades of 100%
post-consumer polyethylene resins.

Materials
Nova Chemicals introduces
three new 100% PE-PCR resins
Nova Chemicals Corporation has developed
and commercialised introduced its first
three grades of 100% post-consumer polyethylene resins, suitable for a range of flexible film applications. The offering includes a
natural linear low/low density polyethylene
PCR (rLLDPE/LDPE), derived from waste
collected from distribution centres and is
suitable for collation shrink, stretch wrap
and e-commerce applications; a natural
rLLDPE/LDPE, made from recycled agricultural film for re-use in agricultural films,
heavy-duty shipping sacks, collation shrink,
and for e-commerce applications; and a
white rLLDPE PCR manufactured from
closed-loop agricultural and irrigation film
recyclate. This latter resin is for use in agricultural film, heavy-duty shipping sacks,
collation shrink, trash bags and liners and
e-commerce applications.
The new grades will allow Nova's customers to integrate more PCR into packaging applications without sacrificing performance, said Greg DeKunder, vice president,
polyethylene marketing, NOVA Chemicals,
" Our goal is for NOVA Chemicals to be a
one-stop resource, providing the products
and technical resources companies need to
achieve their sustainability goals. "
To that end, the company has also recently entered into two supply agreements
with recyclers.
One of these is Revolution, a manufacturer
of plastic films for a variety of consumer and
industrial products and packaging, which
they recover after use to recycle and reuse
in new products. Under this exclusive agreement, Revolution supplies a portion of this
" closed-loop " LLDPE/LDPE PCR to Nova
Chemical for use in packaging applications.
The partnership with Merlin Plastics includes providing financing for a multi-million-dollar project to accelerate Merlin's
further expansion into PCR for food contact
applications. In this way, Nova is working to
secure a reliable supply to offer to its customers. The HDPE PCR resins derived from
this are suitable for use in everyday products
and packaging, including food applications.

Tupperware expands ECO+
line with products made from
Tritan Renew

Tupperware Brands Corporation is expanding
its successful and sustainable ECO+ product portfolio. Next to introducing two new
products, the company has added a new
material partner, Tritan Renew from Eastman. Tritan Renew, derived from Eastman's
proprietary polyester molecular recycling
technology, will allow the production of
glass-like products containing 50% certified recycled content without compromising on quality or clarity. The recycled content is achieved by allocating the recycled
waste plastic to Tritan Renew using a mass
balance process certified by ISCC.

Sabic new compound with
recycled ocean-bound PET
Sabic has launched a new recycled material
made from ocean bound plastic which has
been recovered from ocean-feeding waterways and inland areas within a 50 kilometre radius of the ocean. The ocean bound
material is mechanically recycled and converted into components for new consumer
goods and electronics applications, such as
TV remote controls and electronic razors. It
has the potential to also be used in other
industries in the future, such as automotive.
Part of Sabic's Trucircle portfolio and
services, the new recycled material is a
Xenoy PC/PET compound comprising of a
minimum 10% recycled ocean bound PET
blended with polycarbonate.
According to an internal Sabic LCA Study
based on a resin grade comprising 20%
recycled content, for every 1kT of product
containing the ocean bound recycled Xenoy PC/PET compound, an equivalent of 24
million single-use 0.5liter PET water bottles
can potentially be diverted away from our
oceans, preventing them from becoming

marine litter.
The new material offers potentially significant reductions in carbon footprint of up to
7% and energy consumption of up to 11%
compared to its virgin grade. It has good
impact strength, processability and chemical resistance.
The Trucircle portfolio spans design for
recyclability, mechanically recycled products, certified circular products from feedstock recycling of used plastic, certified
renewables products from bio-based feedstock and closed loop initiatives to recycle
plastic back into high quality applications
and help prevent valuable used plastics
from becoming waste.

line that both
supports
end
market efforts towards more circular solutions and is expected to cut manufacturing
costs by up to 60%. As opposed to conventional autoclave production methods, Sulzer Chemtech's innovative system relies
on extrusion with direct gas impregnation,
offering an easy to implement alternative
with a quick return on investment. Foam
moulders, such as packaging manufacturers, can implement the compounding
line to considerably reduce the costs associated with material supply, warehousing and intermediate transportation. As a
result, companies can offer ePP parts at
more competitive prices while supporting
the adoption of easy to recycle polyolefin
applications.

Sabic's new ocean
