On November 18, the Shirai Group participated in the Tokyo model project “Effective collection and complete recycling of household disposable diapers” commissioned by Toppan Printing, and held a low-carbon collection course for disposable diaper recycling in Hachioji City and Machida City. Announced that it will be optimized using the AI vehicle dispatch system.
Currently, disposable diapers discarded from homes are collected as combustible waste. On the other hand, in this business, pulp and plastic, which are the raw materials for disposable diapers, are recycled as recycled materials, so they are collected in a vehicle different from the conventional combustible waste and transported to the recycling plant. Hachioji City and Machida City will set up model areas for collecting disposable diapers in this project, respectively, and the consignment companies of both cities will collect conventional combustible waste and disposable diapers.
The Shirai Group calculated the shortest route when only disposable diapers were selectively collected in both cities using the AI vehicle dispatch system that has been in practical use since 2014. Based on these results, we will simulate wide-area recovery across both cities and estimate the required number of vehicles when both cities apply to the entire area.
The Shirai Group’s AI vehicle dispatch system uses the AI vehicle dispatch system to calculate about 150 different courses for combustible waste, non-combustible waste, and resources that have been requested to be collected by about 2000 waste generators for each day of the week. It is said that the reduction effect is more than 10% compared to manual work.
In general, local governments nationwide are making efforts to separate and discharge waste by type in order to promote recycling. There are two ways to increase this effectiveness: “separate again after batch collection” and “distribute vehicles by type”, and in reality, further improvement in economic efficiency is important. In the case of separate collection of “distribute vehicles by type” like this initiative, it is possible to eliminate additional vehicles and duplicate routes by collecting them on the most economical course. For this reason, it is possible to reduce carbon dioxide emissions associated with movement.
Founded in 1933, the Shirai Group is one of the few companies that covers both household waste (consigned in the 23 wards of Tokyo) and business waste. With the mission of “rebuilding the venous infrastructure of the city,” he is aiming to innovate the waste business by actively utilizing IT and AI. Specifically, it has commercialized an information platform business that accepts waste treatment and an AI vehicle dispatch system that reduces the number of vehicles dispatched. This time, it is said that it will be a circular economy business to reduce the amount of waste as a society.
In addition, we are proceeding with digitization of waste treatment requests and traceability verification using RFID and blockchain, and by integrating these results, we are planning to accelerate further DX conversion of venous logistics from 2022.
