Garbage composition survey

In Yokohama-shi, we carry out "garbage composition investigation" to examine the separation situation of garbage coming out of home and the situation of Yokohama Pla 5.3 (garbage) plan.

Although the proportion of recyclables in burnable garbage decreased significantly after the expansion of items collected separately, there are still many items such as recycle paper and plastic containers and packaging.
According to a 2023 survey, recycle paper accounts for about 10% of burnable garbage and plastic containers and packaging accounts for about 6%.
In order to promote the separation and recycling of garbage, please continue to cooperate with the separation, referring to "How to separate and dispose of garbage and resources".

Note 1: In fiscal 2004, the percentage of the previous fiscal year prior to the expansion of separate collection items is shown.
(Separated collection items expanded in some wards from the second half of 2004 and in all cities from 2005)

Note 2: In fiscal 2022, we began a survey of used cloth.

About 67% of PET bottles that were properly sorted out by removing the lid and label (Figure 3).
(1) Empty the inside and wash (2) Remove the cap and label and crush (3) crush it (for details, see "Can / Bottle / PET bottle").

About 60% of plastic containers and packaging were correctly sorted as recyclables, and about 40% were mixed in burnable garbage.
In addition, almost 97% of bottles, cans, and PET bottles were properly sorted (Fig. 4).
We look forward to your continued cooperation in sorting, referring to "How to separate and dispose of garbage and resources".
In particular, we ask for your cooperation in correct sorting for plastic containers and packaging.

Of the kitchen garbage contained in the burnable garbage, food loss accounted for about half of the food loss in “untouched food (food that is thrown away without hand)”, “leftover food” and “excessive removal of unedible parts such as vegetable skins” (Figure 5).
In addition, about the amount of food loss generated in 2023, please see "about food loss generated from home".

About 68% of the plastics contained in burnable garbage were "One-way plastic (Note 5)" (blue portion of the outer circle in Figure 6).
Excluding garbage bags, the reduction of one-way plastic was about 52% (red part of the inner circle in Figure 6).
We will continue to separate garbage, and please receive disposable cutlery as much as you need and cooperate with the use of My Bags and My Bottles.

Note 5: It is made of plastic and usually finishes its role after using it.

Example: Plastic containers and packaging, plastic bottles such as beverages and seasonings, plastic tableware such as straws and spoons, etc.

Since there is no specific example of what corresponds to one-way plastic, we have created and investigated our own classification standards in Yokohama City.

※Shopping bags and plastic bags are intended for those used as garbage bags.
