First for a Local Government: Nagoya City to Conduct Waste Collection Demonstration Experiment Using "G-SUPPORT"

ShinMaywa Industries, Ltd. (Headquarters: Takarazuka City, Hyogo Prefecture; President & CEO: Keishi Kutsunohara; hereinafter "the Company") and Lecip Corporation (Headquarters: Motosu City, Gifu Prefecture; President & CEO: Motoaki Kitano; hereinafter "Lecip") have jointly developed the waste collection operational efficiency system "G-SUPPORT." This system has now been adopted for a demonstration experiment by Nagoya City, which aims to implement door-to-door collection for "resource waste."

This experiment will be conducted for three months starting from May 2026, assuming the application of a door-to-door collection method for "resource waste" (paper containers and packaging, miscellaneous paper, PET bottles, empty bottles, empty cans), following the precedent of "general household waste" ("burnable waste," "non-burnable waste," etc.) already introduced in the city. Through "G-SUPPORT," various data related to the operation of waste collection vehicles will be collected, and based on the analysis results, an efficient and sustainable waste collection model will be developed.

Overview of Nagoya City's Waste Collection Demonstration Experiment

In recent years, the amount of waste discharged by local governments nationwide has been on a downward trend due to the promotion of 3R (Reduce, Reuse, Recycle) and population decline. However, the burden on waste collection workers in the field is increasing due to factors such as an aging workforce, labor shortages, and rising temperatures.

Furthermore, with the enforcement of the Container and Packaging Recycling Law and the Plastic Resource Circulation Promotion Law, separate collection of waste has progressed, forcing an increasing number of local governments to consider countermeasures.

Against this backdrop, Nagoya City, which has already introduced the door-to-door collection method for "general household waste," planned this demonstration experiment to identify optimal collection routes and reduce the burden on collection workers before applying the same collection method to "resource waste." In this experiment, "G-SUPPORT" will be installed in the target waste collection vehicles and utilized for acquiring and analyzing various data through actual driving.

Overview of the Demonstration Experiment Related to "G-SUPPORT"

Content

Acquisition and analysis of various collection data to understand the impacts and challenges when switching from the current "station collection method" to the "door-to-door collection method" for "resource waste" collection, which is already applied to "burnable waste," "non-burnable waste," etc.

Period

2026

April: Preparation period
May - July: Data collection through actual driving of refuse compactors subject to the experiment
August: Data analysis, effectiveness measurement report

Target Vehicles

4 waste collection vehicles operating in Nagoya City

Roles of ShinMaywa Industries and Lecip

・Provide "G-SUPPORT" to the 4 target waste collection vehicles
・Collect operational status and route data via the cloud
・Support data analysis and effectiveness measurement for the transition to the new method

Participation in other demonstration experiments: Overview of physical burden assessment for collection workers (ShinMaywa Industries: 2025 results)

Separately from its involvement in the above demonstration experiment, ShinMaywa Industries has been working since 2025, at the request of the Nagoya City Environmental Bureau, to measure and assess the physical burden associated with waste collection operations in the city.

This initiative aims to understand the variation in worker burden based on factors such as age, regional characteristics, collection volume, and temperature, by measuring changes in heart rate, based on the aforementioned issues related to waste. The analysis results are intended to lead to concrete improvement proposals, including the improvement of refuse compactors manufactured by the Company.

This activity was initially planned for only the 2025 fiscal year (single year), but at the request of Nagoya City, the type of waste subject to the survey will be changed in fiscal year 2026, and the activity will continue.

Overview of Physical Burden Assessment for Collection Workers

Survey Location

General waste collection area under the jurisdiction of Nagoya City Minato Environmental Business Office

Participants

12 individuals (collection workers) aged from 20s to late 50s

Measurement Dates

Summer and Autumn (approx. 10-14 days each) Burnable and non-burnable waste collection days during the said period

Weather Data

Temperature and relative humidity (observed values by Nagoya Local Meteorological Observatory)

With the implementation of the demonstration experiment using "G-SUPPORT" in Nagoya City, ShinMaywa Industries will strive to contribute to the efficiency and burden reduction of waste collection in the city, in conjunction with the physical burden assessment of collection workers that has been ongoing since last year.
