Separate and you get resources, mix and you get garbage! By collecting, transporting, and sorting the garbage that people put out every day, we at Koyo are implementing our own vision for a recycling chain.

Targets

12.5　By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse

17. (Original) Implementing resource recycling through group collaboration

 

Initiative details

It is said that by the year 2050, there will be more garbage in the ocean than fish and that 80% of this will be made up of plastic bottles, plastic bags, and other plastic waste produced in towns and cities. Such garbage is dumped into the ocean all over the world, including a great deal from Japan.
In order to reduce the amount of plastic waste produced in this city as much as we can, we are working to convert it into resources. To do this, we start by collecting plastic waste used for containers and packaging (cartons, food trays, etc.) from several municipalities in Hiroshima, Yamaguchi, Okayama, Hyogo, and Osaka prefectures. This is then sent to a sorting line to be separated out by machines and human operators.
The separated plastic waste is then loaded into a large water tank, where it undergoes various processes such as specific gravity separation, centrifuge separation, and thermal drying before finally being turned into raw materials called pellets, which are then used to make products including everyday goods, gardening materials, and civil engineering materials.
The production of pellets also generates sludge, but this is also recycled into organic fertilizer using a wastewater treatment facility and is used to grow corn, potatoes, and komatsuna. This initiative involves all of our group companies, and we are working in partnership to achieve resource recycling.

 

Key Points

With the introduction of plastic bag charges, the issue of plastic waste has become a familiar one in our daily lives. In recent years, with carbon neutrality in mind, the shift of waste disposal methods from incineration to recycling has been gathering momentum.
Reliable sorting is essential for high-quality recycling. The garbage we collect often contains foreign materials such as metal fragments and, more recently, lithium batteries used in smartphones, which can cause fires and other hazards.
In addition to separating garbage, proper garbage disposal by taking a few extra steps, such as washing natto containers, will contribute to better recycling. These garbage problems concern everyone, and we want to convey this information to every citizen of Hiroshima Prefecture.
