PETEC has an R&D Division in its facility. In the division, we are constantly conducting research into new recycling technologies and better methods based on what has been learnt at the recycling site.

Devices and technologies to recover highly pure materials

Recovery of Metals and Decomposition of Wastes

The mixed plastic wastes which consist of various kinds of plastics and metal pieces used to be incinerated in the past. However, PETEC has developed a method to decompose only plastics into harmless gas by adding heated titanium oxide. With this method, PETEC is aiming for zero mixed-plastic waste. It is also possible to recycle the remaining materials after the decomposition.

The Efficient fluorocarbons Recovery Needle

Fluorocarbons used for refrigerators and air conditioners have contain properties that destroy the ozone layer and promote global warming. It has been considered that the complete recovery of fluorocarbons from refrigerators is difficult. So, PETEC had individually developed the efficient recovery needle and introduced it at the site.

Recycling shredded dust

Shredded dust refers to the remains left over when products move from the crushing stage to the sorting stages and has traditionally been incinerated. In combination with traditional sorting technology, PETEC has independently developed and installed equipment to recover high-quality plastics so that usable material can be removed from the shredded dust.

PETEC has many new technologies or processes, some of which were put to practical use for the first time in Japan. These technologies have been patented and widely opened to the public. Thus, PETEC's technologies are useful for the development of recycling technologies in plants outside Japan as well as those in Japan.
