bottlium® is eco-friendly, high-quality PET pellets made from PET bottles collected in reverse vending machines (RVMs) installed at more than 1,600 locations nationwide in Japan. bottlium® itself is made using a proprietary production process with a minimal environmental impact.

People all over Japan who care about the global environment take their empty PET bottles to RVMs so that the bottles can be recycled into PET pellets and thus transformed into a new resource for industry. This consumer-engagement collection system is the foundation of the high quality of bottlium®.

​The recycled PET pellets are used in the manufacture of various apparel products.​*What are PET pellets?
​They are a material made by pulverizing PET bottles for easier processing.

The advantages of bottlium®

1Good coloration

bottlium® is 100% made from plastic bottles that have been provided by consumers as a clean resource after they have removed the caps and labels and rinsed the bottles out. This work by environmentally conscious consumers makes the bottles clear and clean and that in turn makes coloration much easier.

2 Chemical agent-free aqueous cleaning process

In ordinary recycling processes, cleansing agents that are known to be environmentally harmful are used to clean PET bottles. However, in the case of bottlium®, we process bottles using our proprietary technology that employs environmentally friendly ozone water to disinfect and sterilize the material, thereby achieving enhanced cleansing efficacy through the action of nano bubbles. The wastewater is reusable, which makes our washing process even more eco-friendly compared with the methods adopted by comparable PET pellet producers*.*Surveyed recyclers handling 10,000+ tons of PET/year

3Efficient logistics to reduce carbon dioxide emissions

The PET bottles we collect are compressed to one-third their original size in our RVMs at retail outlets and then compressed even more and turned into bales at temporary storage facilities. By enabling each truck to carry more PET material, we have realized a more efficient logistics system with the smallest carbon footprint among PET recyclers in Japan*.​​*Surveyed recyclers handling 10,000+ tons of PET/year

4Area/outlet traceability

Only by using bottlium®*​ can you be sure of the point of collection—the specific area and store—of the PET bottles used to produce its PET pellets.

Many recycling facilities find it difficult to run production lines with a limited volume of material, forcing them to use mixed materials of different origins. We ensure solid traceability by producing PET pellets only from PET bottles that we ourselves have collected.​*Surveyed recyclers handling 10,000+ tons of PET/year

5GRS certified

The [Global Recycled Standard/GRS] verifies recycled content and tracks it from the source to the final product.

Products certified to the [Global Recycled Standard/GRS] contain independently verified recycled content and have met social, environmental, and chemical requirements at each stage of the supply chain, from the recycler to the finished product.


    • PET bottles

    • 1. Collection

      Consumers feed PET bottles
      into our RVMs, which, using
      TOMRA’s unique sensor
      technology, identify and
      collect only those bottles
      that have no label, no cap,
      and no unfinished contents.

    • 2. Compression

      The PET bottles are
      compressed to one-third
      their original size inside the
      RVM. They are further
      compressed and formed into
      bales at temporary storage

    • 3. Transportation

      The two-stage compression
      operation enables efficient
      transportation with reduced
      carbon dioxide emissions at
      all stages of the logistics
      chain, from retail outlet to
      recycling facility.

    • 4. Pulverization

      The bales of compressed PET
      bottles are pulverized and
      any foreign matter is
      carefully removed.​

    • 5. Washing and Sorting

      The pulverized PET goes into
      washing water, where it sinks
      to the bottom and foreign
      matter floats to the top for
      removal. The washing water
      is eco-friendly ozone water
      that disinfects and sterilizes
      the material.

    • 6. Flaking

      When the washed pulverized
      PET is dried, it goes through
      a flaking process and this
      material is then put through a
      special multilayer mesh
      device to remove any
      remaining foreign matter of
      less than 0.02 mm.

    • 7. Dissolving and Extrusion

      The flakes are then put
      through a high-
      deairing process that
      dissolves the flakes and
      extrudes the resulting
      material to be cut into

    • 8. Pelletization

      The extruded material is cut
      into extremely hygienic,
      impurity-free pellets that are
      now ready for processing.


The eco-friendly, high-quality PET pellets can be used to create a wide range of apparel products.
