Basic Approach to Environmental Preservation Initiatives
The UBE Group strives to keep environmental accidents to zero by working to reduce environmental risks. The Group also engages in continuous activities to reduce its environmental impact in order to help ensure sustainable social progress.
The UBE Group also responds to global environmental issues by ensuring that its corporate activities are in harmony with nature and helping to resolve climate change, conserve biodiversity, address the issue of marine plastics, and conserve water resources.
The UBE Group believes that tackling environmental issues to ensure sustainable social progress and fostering stakeholder trust by announcing outcomes are vital for sustainable corporate growth.
Water Resource Usage
The UBE Group has installed pollutant monitoring facilities to manage the quality of water discharges into public waters water. The Group also uses wastewater treatment equipment to clean up plant wastewater that could cause significant pollution.
Emissions Data by Facility
Suppressing Chemical Substance Emissions
The chemical industry complies with laws and regulations while endeavoring to voluntarily cut chemical substance emissions through a disclosure program based on the PRTR Law.*1 The UBE Group chose 20 substances whose emissions are significant*2 from substances subject to the PRTR Law, as well as volatile organic compounds (VOCs)*3, and is striving Companywide to reduce emissions of these substances. In fiscal 2019, we lowered emissions of these 20 substances by 29% from the fiscal 2010 level, suppressing emissions subject to the PRTR Law and VOC emissions.
Suppressing VOC Emissions
The UBE Group’s VOC emissions in fiscal 2019 were 40% lower than those in fiscal 2010.
Suppressing PRTR Substance Emissions
The UBE Group handles 61 of the 462 substances subject to the PRTR Law. The Group’s emissions of these substances in fiscal 2019 were down 33% from fiscal 2010.
Establishing a Recycling-Based Society
Using Resources Effectively
Ube Industries’ cement factories recycle diverse waste and by-products as raw materials (material recycling) and alternative fuels (thermal recycling). The cement kilns operate at up to 1,450°C, so they can burn and detoxify substances that conventional counterparts could not handle. They can also process large waste volumes. It is also possible to use ash from incineration as an alternative to the clay used in cement, thereby eliminating the need to maintain final disposal sites.
In fiscal 2019, the three cement factories harnessed 3.30 million metric tons of waste and by-products, 2.91 million metric tons of which the Company sourced externally, contributing considerably to a recycling-oriented society. (Note)
Ube Industries is developing new businesses to use waste materials in applications other than as materials for cement. For example, we recycle plasterboard, for which we expect demand to increase. We will continue to boost our capacity for handling various waste as part of efforts to expand our recycling business.
Note: Changes in Waste and By-Product Use are shown in Non-Financial Highlights on page 11 of the UBE Group’s Integrated Report 2020.
Reducing Industrial Waste
The Japanese government’s 4th Fundamental Plan for Establishing a Sound Material-Cycle Society targets a 77% reduction in industrial waste landfill amounts from 2000 levels by 2025. The UBE Group endeavors to recycle such waste and cut landfill volume to contribute to a recycling-based society.
Industrial Waste Recycling
The Group’s chemical factories, in-house power stations, machinery factories, and other facilities generate an array of industrial waste, most of which is recycled at cement factories and other Group facilities.
Industrial Waste for External Final Disposal
In fiscal 2019, such waste from Ube Industries and its Group companies was 80% below the fiscal 2000 level. The Group will keep endeavoring to cut volumes in fiscal 2020 and beyond.
