-Asahi Kasei and Microwave Chemical demonstrates project for chemical recycling of polyamide 66
Asahi Kasei and Microwave Chemical launched a joint demonstration project in April 2023 with the objective of commercializing a chemical recycling process for polyamide 66 using microwave technology, said Hydrocarbonprocessing. Chemical recycling – EV-Batteries
The process utilizes microwaves to depolymerize PA66 and directly obtain the monomers hexamethylenediamine (HMD) and adipic acid (ADA), which is expected to be accomplished at high yield with low energy consumption. The monomers obtained can then be used to manufacture new PA66. In the demonstration, scraps from manufacturing and post-use waste material of PA66 for airbags and automobile parts are depolymerized.
Asahi Kasei produces fossil fuel–derived hexamethylenediamine (HMD) and adipic acid (ADA) as intermediates to manufacture Leona PA66, an engineering plastic featuring outstanding heat resistance and rigidity. PA66 is used in various applications, including plastic parts for automotive and electronic products, and yarn for airbag fabric, and its demand is expected to increase worldwide.
As the world moves toward carbon neutrality, attention is increasingly focused on manufacturing processes for reducing greenhouse gas (GHG) emissions from chemical products derived from fossil fuels. Microwave Chemical is promoting technological and business development to achieve carbon neutrality in the industrial sector focused on process development using microwaves, which can directly and selectively heat target substances with high energy efficiency. For chemical recycling, Microwave Chemical is advancing its proprietary PlaWave technology platform for decomposing plastic using microwaves. Chemical recycling – EV-Batteries
Through development combining Asahi Kasei’s experience in manufacturing HMD and ADA for more than half a century together with Microwave Chemical’s achievements in the industrialization of microwave technology, the two companies aim to commercialize a manufacturing process for PA66 that can reduce GHG emissions compared to the conventional manufacturing process.
Laboratory-scale studies that began in fiscal 2021 have confirmed the high-yield depolymerization of PA66 using microwaves, as well as the principle of the separation and purification process after depolymerization. Bench-scale equipment will now be assembled at Microwave Chemical’s Osaka Factory by the end of fiscal 2023, and a small-scale demonstration trial using this equipment will be performed in fiscal 2024 to collect basic process data for commercialization.
Microwave Chemical’s PlaWave technology platform for decomposing plastic using microwaves can depolymerize PA66 with low energy and obtain HMD and ADA monomers in high yield. The manufacturing process for PA66 using HMD and ADA obtained by depolymerization with this technology is expected to reduce GHG emissions compared to the conventional PA66 manufacturing process, while further reduction of GHG emissions may be achieved by the use of renewable energy for the power required to generate the microwaves. Chemical recycling – EV-Batteries
By verifying the process from depolymerization to separation and purification in an integrated manner, this demonstration project aims to enable resource circulation of PA66 for further reduction of GHG emissions.

-Rare earths are not used for making batteries in electric cars, but for making magnets in electric motors.
The term “rare earths” refers to 17 specific chemical elements, including scandium, yttrium, and the 15 elements known as lanthanides. Chemical recycling – EV-Batteries
Rare earths are found in ores in low concentrations and are difficult to extract and refine. They are divided into three groups based on their atomic number.
In electric cars, rare earths are used to make magnets that power the electric motor.
The magnets use elements such as neodymium, samarium, terbium, or dysprosium. Magnets that use rare earths are the most powerful, and they can produce magnetic fields higher than 1.6 Tesla, which is why they are used for electric cars.
The most common magnets are made of neodymium, iron, and boron (NdFeB) or samarium and cobalt (SmCo).
To reduce costs and the environmental impact of magnet production, many companies are working to eliminate rare earths from the electric motors of the future.
Tesla and other companies are using technological advances to create similar performance with different formulas. Chemical recycling – EV-Batteries
Researchers at the Critical Materials Institute are working on magnets with manganese and bismuth (MnBi) with a special structure that can increase performance as the temperature rises.
