Experts from THOR and BASF Plastic Additives have worked together for several years to develop solutions to meet flame retardant specifications for applications with a focus on replacing halogenated flame retardants. Both parties are active members of the Phosphorus, Inorganic and Nitrogen-based flame retardant association PINFA, working closely together to provide sustainable polymer systems that withstand ignition and flame propagation during their use.


BASF supplies antioxidants to 3T Company


For stable recycling of HDPE sheets


BASF and 3T Industries, helping pineapple cultivation in Malaysia to increase its production and save resources. 3T Industries uses BASF's IrgaCycleUV033 DD additive to improve 100% recycled high-density polyethylene (HDPE) sheet for use as a pineapple protector.


When pineapples require a warm and humid climate, they are susceptible to damage from solar radiation and high temperatures (> 32°C), which greatly reduces market yields and reduces growers' profits. HDPE protector protects the fruit from direct sunlight while allowing photosynthesis to occur.


IrgaCycleis available as a one-pack solution, giving the recycler immediate access to the solution without further pre-blending. It is also more effective than traditional antioxidant systems, reducing the overall number of adjuvants required.


This results in easy and precise metering, improved product quality, and upgraded recycled materials for long-term applications. BSAF not only provides the 3T process with a suitable additive solution, but also provides a recommended solution to stabilize the polymer during processing and outdoor weathering. This is important because an efficient and sustainable application of recycled materials depends on the optimization of processing conditions and modification aids, among others.


IrgaCycleincludes a range of plastic additive formulations that allow recycled plastics to be combined with virgin materials for the production of high-value plastics. This additive package addresses specific quality issues associated with recycled resins, such as limited processability, poor long-term thermal stability, and insufficient protection against outdoor aging.


New processing aids from Riverdale Blocks electrostatic charge on plastic surfaces


Riverdale Global introduces +Zero Processing Aid, which prevents surface charge build-up during processing of plastic parts, and also acts as a good mold release agent, reducing cycle time by up to 25% by reducing surface tension.


At Riverdalethe, the approach is to create carrier systems to add value to processing and to support pigments in carriers. Innovative carrier technology that enables higher pigment concentrations, better compatibility with engineering resins, and longer stability, especially for pearlescent and metallic colors.


The new carrier system also allows the polymer to flow more easily with less heat, which in turn reduces injection and cooling times. It also makes it possible to use 100% comminuted stock, and as a result processors will see good mold release, whether using virgin or regrind.


The new and improved +Zero formula has a higher concentration, which will result in lower usage levels resulting in significant cost savings. This new processing aid also provides improved regrind processability, as the newly formulated additive allows the use of higher percentages of recycled material, as well as the use of lower grades of regrind. Flow and dispersion are improved with consequent reductions in cycle times.


         Dow and Valoregen Partner

          Construction of the largest mixed recycling site in France


Dow has announced an agreement with French recycling company Valoregen to continue construction of the largest single hybrid recycling site in France, owned and operated by Valoregen.


The collaboration is another example of Dow working with companies across Europe and around the world to invest in innovative new recycling options, accelerate the circular economy and tackle plastic waste.


The project, which is expected to start operations and deliver recycled materials in the first quarter of 2023, will mark an important step in both mechanical recycling (processing certain plastic waste into secondary products) and newer more advanced recycling processes (which will Waste plastics and hard-to-recycle plastics are degraded into a liquid form similar to naphtha to make resins like virgin materials).


Valoregen's ultimate goal is to create a unique ecosystem capable of recycling all forms of plastic waste in one place. Both mechanical recycling and advanced recycling technologies are complementary and fundamental to achieving Dow's ambition to add at least 100,000 tonnes of recycled plastic to its product options sold to the EU by 2025.


By incorporating these technologies in the same plant, the plant will increase energy efficiency by making yields greater than 80%, well above the average conventional mechanical recovery efficiency of 60-70% - minimizing waste - due to the use of a Intelligent energy management system. Valoregen will also reduce the combined carbon emissions generated by these processes as it works to limit the transportation of waste products to different locations.

SDK and partner development

Microwave-based chemical recycling technology


Showa Denko (Showa Denko = SDK) and Microwave Chemical Co., Ltd., began to jointly develop a new microwave-based chemical recycling technology that directly converts used plastics into chemical raw materials. The two companies are taking various steps to reach carbon neutrality by 2050 and aim to commercialize the new technology in the near future.


SDK and Microwave Chemistry aim to develop a technology that uses radiated microwaves to break down used plastic containers, from which basic chemicals like ethylene and propylene are produced.


By the end of the year, the two companies will study the conditions for forming products through microwave heating, look for catalysts to improve yields of target components, and try to optimize the conditions and processes for decomposition to establish the basic technology.


Compared to other heating methods, microwave heating is special because it only heats the target. In the planned process, we will use microwave absorbers (fillers) to radiate energy to the used plastic in a focused manner, causing the used plastic to break down into base chemicals.

SDK has been in the chemical recycling business at its Kawasaki City plant since 2003, producing clean hydrogen and ammonia through the pyrolysis of used plastics. Therefore, SDK has accumulated comprehensive knowledge related to raw material procurement, disassembly and manufacture of end products.


With these high levels of technology and deep experience in process development, Microwave Chemicals has the ability to advance microwave technology. In the field of chemical recycling, the company has established "PlaWaveTM", a microwave-based plastics decomposition technology platform that enables the processing of various types of plastics.

Solvay's new stabilizer portfolio

Protect polyolefin surfaces


Solvay announced the development of a new portfolio of UV-C stabilizers. They are designed for demanding hygienic applications, where the polyolefin surface is treated with UV-C (200-280nm) ultraviolet light to combat COVID-19 and hospital-susceptible infections.


The new proprietary stabilization technology represents an important milestone for the polyolefin industry as it is the first to address polyolefin degradation, discoloration and microcrack formation caused by frequent exposure to UV-C radiation of.


Solvay has developed an engineered application technology that can use UV-C light as an antimicrobial agent for the sterilization of polyolefin surfaces while safely protecting these surfaces from UV-C-induced degradation.

UV-C irradiation can inactivate microorganisms and is scientifically proven to be effective against the new coronavirus. However, the proven UV-C germicidal effect also exposes the treated surface to much higher UV energy than conventional UV-A and UV-B stabilizers, potentially accelerating material degradation.


Solvay's new UV-C stabilization technology targets a wide range of polyolefin applications, including surgical medical equipment and patient rooms, aircraft and shared vehicle interiors, and sports venues.


Solvay says its new UV-C stabilization technology helps end users achieve levels of UV-C disinfection that are effective on surfaces of polyolefin parts without sacrificing material performance.
