Environment – Effective Utilization of Resources
Targets of the 8th Environmental Plan (Fiscal 2016 to 2018) and Achievements in Fiscal 2017
The Mitsubishi Electric Group focuses on the following three measures to reduce final disposal ratios: thorough analysis and separation of waste for conversion to valuable resources; higher levels of conversion to valuable resources through development of disposal contractors and sharing information about waste disposal contractors; and increased efficiency in waste (recycling) logistics.
The target final disposal ratio under the 8th Environmental Plan (fiscal 2016 to 2018) is less than 0.1% for Mitsubishi Electric and Japanese affiliate companies. In fiscal 2017, both parties achieved this target, with Mitsubishi Electric achieving a rate of 0.002% and Japanese affiliates bringing their ratio down to 0.04%. Overseas affiliates had a final disposal ratio of 0.69%, narrowly failing to reach the fiscal 2017 target of 0.6% or less.
Results of Activities at Mitsubishi Electric
Each Mitsubishi Electric production base manufactures different products and so generates different kinds of waste. Our general rule is therefore to create and implement a different plan for each base. However, we also endeavor to share management expertise and information on contractors, and cooperate with neighboring bases.
Increased production in fiscal 2017 led to total final disposal rising to 86,000 tons, a slight increase over the previous fiscal year, but at 0.002%, the final disposal ratio was in line with that of the previous fiscal year.
The scope of our waste management system has been expanded from our own 26 production bases to cover our branch companies in order to enhance our legal compliance.
We will continue to develop strategies for improvement, such as reducing the amount of waste sent for subcontracted disposal.
Results of Activities at Affiliates in Japan
Expanded scale of business operations and other factors meant that the total final disposal figure of 64,000 tons in fiscal 2017 was slightly higher than the previous year. Final disposal ratio was improved to 0.02%.
Our own waste management systems were introduced at our affiliates in Japan to enhance legal compliance, and are in use at approximately 140 companies. Their use will be extended later to offices and other locations. We also plan to continue to digitize manifests.
Results of Activities at Overseas Affiliates
It is difficult to set the same target levels as Japan for overseas affiliates, as regulations and waste treatment practices vary by country and region. Nonetheless, we aim to lower the final disposal ratio from 0.87% in fiscal 2015 to less than 0.5% over the three years covered by the 8th Environmental Plan.
To achieve this, we will focus our efforts on selected specific sites that require special prioritization and improvement, and improve their results through thorough separation and increased use of recycling in order to increase overall performance among our overseas affiliates.
Increased overseas production in fiscal 2017 and other factors increased final disposal to 72,000 tons and the final disposal ratio to 0.69%, both figures higher than the previous fiscal year.
In future, in addition to cooperation between neighboring bases with the aim of meeting our targets in line with local regulations, we will formulate more detailed plans and follow overseas activities more closely in an attempt to reduce the amount of waste output and the final disposal ratio.
