Policies and Framework for Implementation
In addition to recycling and reuse of materials, the DIC Group works to minimize the impact of its industrial waste disposal practices.
The DIC Group aims to minimize industrial waste and promote the recycling and reuse of materials. Since fiscal year 2001, DIC has promoted zero emissions initiatives, the goal of which is to reduce the volume of waste disposed of as landfill by 95% from the fiscal year 2000 level. In fiscal year 2008, the Company expanded the scope of these initiatives to include Group companies in Japan. With the aim of expanding efforts across the global DIC Group, in fiscal year 2013 DIC introduced MBO at overseas Group companies. DIC subcontracts the treatment of industrial waste to be disposed of as landfill and ensures that waste is properly treated by promoting strict compliance and on-site confirmation by designated departments at each of its production sites.
Principal Initiatives in Fiscal Year 2020
The DIC Group works to fully grasp and manage industrial waste from generation at production facility through to discharge, intermediate treatment and final disposal as landfill. The Group works actively to reduce its disposal of industrial waste as landfill by recycling cinders, dust and sludge, among others, into roadbed materials and raw materials for cement, using thermal recycling to recover waste heat and minimizing production losses by increasing throughput yields.
Initiatives by the DIC Group in Japan
In fiscal year 2020, the total volume of industrial waste generated decrease by DIC Group production facilities in Japan amounted to 32,564 tonnes,
down 37% from fiscal year 2019. The principal factors behind this decline were the absence of a spike in emissions in fiscal year 2019 caused by an
accident at the Saitama Plant involving a warehouse and a decrease in production volume as a result of COVID-19. Industrial waste disposed of as
landfill by Group companies in Japan fell 23%, to 167 tonnes, reflecting improved resource recycling rates at production facilities. Going forward, the
DIC Group will continue working to reduce industrial waste disposed of as landfill by individual production facilities in line with its goal of achieving
DIC Group companies in Japan also continued working to ensure the appropriate disposal of PCBs. In addition, these companies promoted the rigorous management of unprocessed waste, including transformer, capacitors and stabilizers, through proper collection and storage in warehouses.
Deployment of a Comprehensive Industrial Waste Management System
In fiscal year 2016, the DIC Group in Japan resolved to introduce GENESYS ECO, a comprehensive industrial waste management system for use with the country’s Electronic Manifest (e-Manifest) system. The e-Manifest system manages the movement of industrial waste by facilitating the electronic transmission of manifest information and tracking the flow of waste from generation to final disposal. Unlike paper manifests, the e-Manifest system offers easy data input and eliminates the need for administrative reporting and storage by generators. In fiscal year 2019, deployment of GENESYS ECO was completed at all 36 of the Group’s manufacturing sites in Japan, an achievement that has helped to both save labor and ensure legal compliance.
GENESYS ECO has helped to both save labor and ensure legal compliance.
Owing to the partial revision of Japan’s Waste Management and Public Cleansing Law, Japanese companies with sites that discharge 50 tonnes or more of what is classified as “specially controlled industrial waste” are obliged to introduce the e-Manifest system by April 2020. DIC took swift steps to comply with this requirement, achieving full-scale introduction in fiscal year 2017. The following year, we expanded deployment to include Group companies and systematized manifest notification, thereby lowering the risk of legal violations. Further, simplifying procedures for issuing manifests and automating annual reporting to authorities has helped us to both save labor and ensure compliance. However, because the timing of deployment has varied, the capabilities of pertinent personnel vary from one site to another. Accordingly, we will take steps to further standardize procedures and correct disparities in skill levels.

Initiatives by the DIC Group Overseas
In addition to ensuring the disposal of industrial waste in a manner that complies with national and regional legal and regulatory requirements, the DIC
Group’s overseas production facilities work to minimize industrial waste through the voluntary recycling and reuse of materials. Production facilities in the
Americas and Europe, Greater China and the Asia–Pacific region are introducing new waste treatment facilities and promoting the horizontal deployment of
best practices, including those aimed at improving production processes.
In fiscal year 2020, industrial waste generated by DIC Group production sites overseas dipped 5.0%, to 59,792 tonnes, while industrial waste disposed of as landfill by these companies decreased 6.0%, to 19,058 tonnes. Looking ahead, the Group’s overseas regional headquarters will focus on further reinforcing compliance with local laws and regulations, while at the same time cooperating with the Responsible Care and production management departments to further curb the generation of industrial waste and the disposal of such waste as landfill by the DIC Group overseas.
Industrial Waste Generated by the Global DIC Group in Fiscal Year 2020
The definition of “industrial waste”—including whether it encompasses both toxic and nontoxic substances, and both hazardous and nonhazardous substances—vary in
different countries and regions, as does the methods used to dispose of such waste. The DIC Group works to ensure the management of industrial waste in a manner
appropriate for the degree of danger posed and in accordance with the laws of the countries and regions in which its sites are located. The Group also grasps and manages
processes for managing industrial waste on a global basis, from generation to discharge by production facilities, intermediate treatment and final disposal as landfill.
The table below provides detailed data on industrial waste generated by the DIC Group in Japan and overseas in fiscal year 2020. The Group collects data for volume generated, volume discharged by production facilities, volume recycled (material recycling), waste heat recovered (including that from incineration boilers), waste heat not recovered (including that from simple incineration) and volume disposed of as landfill for industrial waste, which it categorizes as “toxic” or “nontoxic.”
Environmental Impact of Groupwide Environmental Initiatives
The DIC Group quantifies the environmental inputs (consumption of energy and other resources) and outputs (emissions into the environment) of its operating activities, and
uses its findings to formulate comprehensive and efficient strategies for reducing its environmental footprint.
The chart below is a comprehensive illustration of the environmental impact of the DIC Group’s operating activities in Japan and overseas in fiscal year 2020. The chart shows environmental impact for two input items (total energy consumption and total water consumption) and three output items (emissions into the air, emissions into water and emissions into soil) in the following categories: CO₂ emissions, wastewater discharged, industrial waste disposed of as landfill, emissions of targeted substances into air (551 chemical substances—including those designated under Japan’s PRTR*1—and one substance group*2) (Japan only), emissions of NOx, emissions of SOx and COD in wastewater.
- A PRTR is a scheme for assessing, aggregating and disseminating data on the source of hazardous chemicals, amounts released into the environment and amounts transferred off-site from industrial establishments via waste products.
- The “551 substances and one substance group” comprises 462 chemical substances designated by Japan’s PRTR and 89 PRTR-designated substances (other than class 1) and one substance group (chain hydrocarbons with up to 4–8 carbon atoms) targeted for study by the JCIA.
