Promote recycling. Promote recycling at DIC Group companies and strive to improve resource recycling. DIC Group (Japan) resource recycling rate: 86% (-3 percentage points from fiscal year 2015). Promote recycling at DIC Group companies and strive to improve resource recycling.
  • Evaluations are based on self-evaluations of current progress. Key: ★★★ = Excellent; ★★ = Satisfactory; ★ = Still needs work

Basic Approach

The DIC Group aims to minimize industrial waste by recycling and reusing materials. Since fiscal year 2001, DIC has been involved in a zero emissions initiative* aimed at reducing industrial waste disposed of as landfill. DIC has deployed zero emissions initiatives at DIC Group companies in Japan since fiscal year 2008. With the aim of expanding efforts across the global DIC Group, in fiscal year 2013 DIC began to introduce 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 facilities.

  • *Zero emissions initiatives: DIC is promoting initiatives aimed at reducing the volume of waste disposed of as landfill by 95% from the fiscal year 2000 level.

Principal Initiatives in Fiscal Year 2016

Reducing Industrial Waste Disposed of as Landfill

The DIC Group works actively to reduce its disposal of industrial waste as landfill by recycling cinders, dust and sludge into, among others, roadbed materials and raw materials for cement, using thermal recycling to recover waste heat and reducing production losses by increasing yields.

In fiscal year 2016, the total volume of industrial waste disposed of as landfill by the DIC Group in Japan increased 31.8% from fiscal year 2015, to 183 metric tonnes. This was due principally to a temporary increase in sludge disposed of as landfill by the Tokyo Plant accompanying steps taken to optimize the facility’s wastewater treatment process, which amounted to 56.0 metric tonnes, as well as a higher residue rate for intermediate industrial waste processing at the Kashima Plant. In fiscal year 2017, all DIC Group companies in Japan will step up the implementation of measures aimed at reducing the total volume of industrial waste generated by its production facilities from the fiscal year 2016 level, while at the same time promoting zero emissions initiatives.
DIC and DIC Group companies in Japan also continued working to ensure the appropriate disposal of polychlorinated biphenyls (PCBs). In addition, these companies promoted the strict management of unprocessed waste, including transformers, capacitors and stabilizers, through proper collection and storage in dedicated warehouses.

TOPICS Comprehensive Industrial Waste Management System Introduced

Differences Between E-Manifests and Paper Manifests

In fiscal year 2016, the DIC Group in Japan explored the introduction and conducted tests of 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 of the flow of waste from generation to final disposal. Unlike paper manifests, e-Manifests offer easy data input and eliminates the need for administrative reporting and storage by generators.
With anticipated revisions to Japan’s Waste Management Law expected to increase demand for greater manifest data transparency, DIC resolved to introduce an industrial waste management system that would facilitate the efficient collection of data while also ensuring legal and regulatory compliance. The Group has completed evaluation of the system at several sites and intends to gradually expand deployment in fiscal year 2017.

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.
In fiscal year 2015, DIC Group companies in the Americas and Europe, Greater China and the Asia–Pacific region deployed measures aimed at achieving reductions in industrial waste generated during various production processes that exceeded nationally and regionally mandated levels. Nonetheless, the total volume of industrial waste generated by DIC Group production facilities overseas rose 5.7%. Looking ahead, regional headquarters in these areas will focus on further reinforcing compliance with local laws and regulations while at the same time cooperating with DIC’s Responsible Care and Production Management departments to analyze the reasons for this increase with the aim of curbing the generation of industrial waste and reducing the volume of industrial waste disposed of as landfill.

Environmental Impact of the DIC Group’s Operating Activities

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 domestic operating activities in fiscal year 2016. The chart shows environmental impact for two input items (total energy consumption and total water consumption) and six output items (emissions of 551 chemical substances (including those designated under the PRTR*1) and one substance group*2, emissions of CO2, emissions of NOx, emissions of SOx, COD in wastewater and industrial waste disposed of as landfill).

Environmental Impact of the DIC Group’s Operating Activities

  • *1The PRTR is a scheme in Japan for assessing, aggregating and disseminating data on the sources of hazardous chemicals, amounts released into the environment and amounts transferred off-site from industrial establishments via waste products.
  • *2The “551 substances and one substance group” comprises 462 chemical substances designated by the PRTR and 89 substances and one substance group targeted for study by the JCIA.

TOPICS DIC India Celebrates World Environment Week

The DIC Group promotes diverse ESH initiatives in countries and territories around the world. In June 2016, DIC India Ltd. celebrated World Environment Week, a campaign aimed at reinforcing the company’s commitment to ongoing environmental protection. Individual days during the week were assigned specific themes and named accordingly—for example, Water Conservation Day, Energy Conservation Day and Waste Minimization Day—and a variety of programs were offered, including theme-specific employee awareness training. DIC applauds these and other voluntary initiatives that enhance employees’ understanding of environmental and safety issues and recognizes the importance of such efforts in helping to realize a sustainable society.

TOPICS Reducing Industrial Waste: Efforts to Promote Recycling at DIC EP’s Sodegaura Plant

At the Sodegaura Plant we produce polyphenylene sulfide (PPS) polymer, an engineering plastic. PPS polymer is a thermoplastic resin with excellent heat and chemical resistance that has a wide range of applications, from electronic components and residential hot water heater parts to parts for automobile interiors, for which they are fortified with glass fibers or another material and used as compounds. An alternative to metal, PPS polymer is light and suitable for high-volume production, making them extremely useful in reducing energy use (by improving fuel efficiency).
There are two main kinds of industrial waste produced at the Sodegaura Plant. The first is sludge, a low-molecular-weight material (polymerization residue, reaction solvent, etc.) that is a byproduct of polymerization reactions. The second is waste alkali (the product of allowing unreacted sodium sulfide to be absorbed in a caustic soda solution). Full-scale efforts to reduce industrial waste began in fiscal year 2002. Since fiscal year 2008, we have worked to improve our recycling efforts. Consequently, in fiscal year 2010 we succeeded in reducing energy usage per unit of production for low-molecular-weight materials and waste alkali by 70% and 50%, respectively, from fiscal year 2002. This was accomplished by repeatedly outsourcing recycling operations to interim waste treatment companies and by processing more hard-to-treat industrial waste. Our efforts in promoting recycling by organizations reusing these materials also paid off in fiscal year 2010. Going forward, we will continue to promote recycling as well as to examine ways in which waste alkali could be put to use as sodium hydrosulfide.
