-Amcor technology to help process small plastic bottles often lost in the recycling process
Amcor Rigid Packaging (ARP) has debuted a technological advancement that makes it possible for billions of small bottles to be recycled.
ARP is first applying the technology to 50 mL spirits bottles. These bottles, while made of recyclable polyethylene terephthalate (PET), are often lost in the recycling process due to their small size. Most people recognize these as the little liquor bottles often served on airplanes. Despite its material being infinitely recyclable, the size of these bottles presents challenges at most U.S. material recycling facilities. The bottles tend to slip out of the sorting process where broken glass is filtered out for disposal.
“We know that many small bottles are falling through screens in our MRFs designed to separate glass, so this is a major development – it allows these bottles to pass this step in the process and have the opportunity to be captured by the appropriate equipment downstream. At a time when the recycling industry is constrained by material supply, every additional pound diverted from waste makes a big difference,” said Curt Cozart of the Association of Plastic Recyclers.

With its pledge to develop all its packaging to be recyclable, compostable or reusable by 2025, Amcor is always innovating to increase the recyclability of its products. Seeing an opportunity for improvement, ARP’s team of engineers examined the issue and began designing a container that collapses in a controlled way to maximize its width. With a collapsed width greater than 5 cm, this design would no longer slip through the cracks at most U.S. recycling facilities.
“This discovery was made by the Amcor team when testing revealed that the bottles collapse in different ways,” said Terry Patcheak, VP of Research & Development and Advanced Engineering at ARP.
-Festive season 2021 auto demand worst in decade: FADA
Semiconductor shortages, petrol prices and weakening demand for two-wheelers and entry-level passenger cars impacted sales during the 42-day festive season in 2021, said FADA
Auto dealers await the festive season with bated breath every year with almost double the average sale volumes across segments during the period. However, in 2021, semi-conductor shortages and subdued demand in the entry-level segments ushered in what was described as the “worst festive season in a decade” for dealers this year.
According to the Federation of Automobile Dealers Associations (FADA) while demand was healthy in SUV, Compact-SUV and luxury categories, dealers couldn’t do brisk businesses owing to shortages of vehicles. Light Stabilizers Plastic Recycling
“On the other hand, entry-level cars saw subdued demand as customers in this category continued to conserve money due to their families healthcare needs,” said FADA President, Vinkesh Gulati in a statement released along with vehicle retail data for October 2021 and 42 days festive period.
During October 2021, vehicle sales declined by 5.33% year on year at 1.36 million as compared to 1.44 million vehicles sold in October 2020 and 1.86 million sales during October 2019, as per FADA data.
Two-wheeler sales continue to remain subdued owing to rural distress due to triple-digit petrol prices and reduced spending capacity as consumers preferred to conserve cash for healthcare emergencies in wake of the pandemic.

-Toray Industries : Develops Transparent, Heat-Resistant Film for 5G Communications
Toray Industries, Inc., announced today that it has developed a new film for 5G communications. The film offers excellent transparency, heat-resistance, flame-retardancy, and dielectric performance.
Wide-ranging prospective applications include transparent 5G antennas, transparent flexible printed circuit boards (see Glossary note 1), transparent heater substrate materials, and other electronic components. They would also encompass construction materials that benefit from the film’s transparency and flame retardancy, and process release films requiring chemical and heat resistance to ensure visibility for inspections and positioning. The company has begun providing samples to users, and will keep pushing ahead with R&D to accelerate commercialization.
5G technology offers ultra-fast communications for broadband cellular networks but also requires numerous antennas. That is because it uses higher frequency radio waves with short ranges. This situation propelled efforts to explore transparent antennas with good visibility and design that can be installed in all sorts of locations. Existing transparent circuit boards employ polyethylene terephthalate film and transparent polyimide film because they are light and unbreakable. However, their dielectric loss tangent (see Glossary note 2) are high, causing large signal losses in 5G communications.
On the other hand, the Toray-developed Torelina®, is ideal for 5G circuit boards because of its outstanding heat resistance, flame retardancy, electrical insulation, and consistently low dielectric loss tangent in varying temperature and humidity conditions.
Torelina® is the world’s only bi-axially oriented polyphenylene sulfide film (see Glossary note 3). However, the film is opaque, with the typically yellow tinge of heat-resistant polymers. That is because tiny voids inside the film scatter light and result in low transparency. Light Stabilizers Plastic Recycling
-Unitika Debuts CNF-reinforced Polyamide, but It’s the Other CNF
A polyamide 6 grade from Japan’s Unitika is reinforced with CNFs, in this case cellulose nanofibers rather than carbon nanofibers. The sustainable solution based on plant-derived fibers is reportedly readily recyclable, and targets application in automobile parts, home appliances, and outdoor goods. Unitika also reports three recycling cycles are achievable with no apparent degradation in properties.
Key to development of the new composite materials is dispersion of the CNFs at high loading without having to modify the fibers. Unitika has been able to replicate or even better the physical properties of 30% glass-fiber-reinforced polyamide 6 with its CNF-reinforced grade. Light Stabilizers Plastic Recycling
