Reducing the Risk of Chemical Substances
Green Procurement System
Preparing a system designed to comply with regulations around the world
Konica Minolta implements green procurement, assessing the chemical constituents of parts and components and giving preference to those with the least environmental impact. Konica Minolta’s green procurement meets international standards. In 2012, the Group incorporated the International Electrotechnical Commission’s IEC 62474 standard, in order to ease the data-gathering workload on suppliers as much as possible in today’s increasingly complex regulatory environment. The Group also periodically holds supplier briefings on trends in environmental laws and regulations and revisions to Konica Minolta standards.
The Group introduced its current green procurement system in 2009, overhauling the previous system. The system has been made to comply with the tightening of regulations on chemical substances in products, expanding its coverage to include candidate SVHCs for authorization and other substances restricted under REACH regulations. The Group is keeping an eye on trends in regulations and alternative technologies and is working on plans to eliminate hazardous materials in order to be sure it avoids risks.
- REACH regulations: Regulations enacted by the EU in June 2007 concerning the registration, evaluation, authorization and restriction of chemicals, to consolidate existing regulations concerning chemical substances.
Overview of the SIGMA Green Procurement System
● Japanese, English and Chinese language support
● Supports two standard chemical substance surveys (JAMP*1 and JGPSSI*2) and independent methods
● Separates the procedures for checking for prohibited substances and for collection of information on reported substances in products
● Sharing information of survey and response with business partners
● Databasing of communication records ensures compliance through tracking
● Simplifies the response to changes in regulations and substances subject to control
- JAMP: Standards for chemical substance surveys established and implemented by the Joint Article Management Promotion-consortium.
- JGPSSI: Standards for chemical substance surveys established and implemented by the Japan Green Procurement Survey Standardization Initiative.
Advanced Evaluation of Chemical Risks
Using its unique safety verification system to achieve the appropriate management of chemicals
Konica Minolta has established the Safety Verification System for advanced investigation of risk management related to the adoption of new chemicals. When the Group cannot avoid using a chemical that poses a high degree of risk, the safety screening meeting is convened to establish rigorous requirements of control.
The evaluation scheme takes into account the forms of exposure that occur when the chemical is used, in addition to the hazards specific to the chemical and the quantities of the substance used. Exposure risk is classified into four categories ranging from “when used under rigorous safety controls (at production sites and the like)” to “when several, unspecified users are envisioned and safety controls cannot be guaranteed.” The system has established safety requirements for chemicals that take into account the various circumstances of use. In addition, after the chemical has been introduced into a manufacturing process, it is possible to reevaluate the risk according to changes in the amount used and the conditions of use.
This system has resulted in a more rational risk assessment of product safety, environmental protection, and occupational safety, and thus more appropriate control.
Reduction of Atmospheric Emissions of VOCs
Implementing a unique risk management index to reduce VOCs
Since 1993, Konica Minolta has worked to reduce atmospheric emissions of volatile organic compounds (VOCs) at its production sites around the world, focusing on VOCs with higher risks based on hazard and volume. The Group worked systematically to eliminate the use of highly hazardous solvents by fiscal 2010, and it has been maintaining this state since fiscal 2011.
The Group has established its own environmental impact index as part of the Medium-Term Environmental Plan 2015, with the aim of reducing the use of substances that pose a risk to ecosystems or may have an indirect environmental impact, as well as substances that pose a direct risk to human health or a risk of atmospheric pollution. In fiscal 2012, VOC emissions were down 75% from fiscal 2005, meeting the annual target. The Group will maintain this state into the future.
|Chemical Substance||Achievement Year|
|Hazard coefficient||Example of substances|
|Substances that pose a risk to human health Substances that pose a risk to ecosystems Substances that pose a risk of atmospheric pollution||×100||1, 2-Dichloroethane|
|×10||dichloromethane, Ethyl acrylate n-heptane|
|Substances that pose an indirect impact on the environment||×1||isopropyl alcohol, methanol, ethanol, acetone, ethyl acetate|
- Environmental impact index:
Environmental impact index (point) = Atmospheric emissions of VOCs [t] × Hazard coefficient × Location coefficient
Hazard coefficient: Set at 1-fold, 10-fold, or 100-fold depending on the severity of the impact on human health and the environment (set independently by Konica Minolta based on the coefficient used in the safety evaluations conducted by Kanagawa Prefecture in Japan)
Location coefficient: Outside the industrial estate 5, inside the industrial estate 1
Fiscal 2012 Targets and Results (compared with fiscal 2005)
Self-assessment *** Achievement more than 100% ** Achievement more than 80% and less than 100% * Achievement less than 80%
|Objectives||Fiscal 2012 Targets||Fiscal 2012 Results||Self-assessment|
|Reducing the risk of chemical substances||Atmospheric emissions of volatile organic compounds (VOCs)
(environmental impact index):-70.5%
Countermeasures against Contamination of Soil and Ground Water
Konica Minolta is conducting robust management through periodic observation at sites in Japan where soil or ground water contamination has been identified to ensure that the contaminants do not affect the surrounding environment. The Group has organized a specialist team to manage remediation of polluted sites and to prevent the spread of contamination. Detailed surveys conducted under the team's supervision serve as the basis for developing countermeasures and examining suitable purification technologies. The Group reports the results of its observations and remediation efforts periodically to local government agencies and to concerned neighboring residents.
Establishment of guidelines for managing soil contamination risk
Guidelines have been set for risk management of soil contamination as part of Konica Minolta's unique Green Factory Certification System for comprehensive evaluation of the environmental activities of its production sites, as the certification standards for Level 2 require compliance with these guidelines, from April 2011.
Guidelines for managing soil contamination risk
● The risk of soil contamination has been assessed through preliminary surveys at production sites known to have a high risk from past surveys.
● If soil contamination (in excess of the standard value) is observed, measures are taken to prevent damage to human health.
● Measures are also taken to prevent run off of contamination outside the site.
