Environmental Protection

MHIENG is committed to creating a circular society by reducing CO2 emissions, energy use, waste reduction, chemical substance management, water resource protection, etc., and by developing and expanding sales of products and systems with environmentally friendly designs, we will contribute to solving environmental issues around the world and realizing a carbon-neutral society.

As the global trend toward decarbonization accelerates, we are providing solutions using CO2 capture technology to solve the social issue of CO2 reduction faced by many countries and companies.

The low-carbon transportation system is a clean product, and the vehicles and related parts manufactured at the Mihara plant employ unique technologies for the reduction of environmental load, such as the use of aluminum to reduce weight (reduce power consumption), the use of unpainted vehicles to reduce VOC (*) emissions, and the elimination of lubricants with oil-free compressors.

Environmental protection activities

MHIENG fulfills its responsibilities for its products used in society and as a manufacturer.
The environmental risks (environmental aspects/environmental impacts) of each project are evaluated in advance, and the product life cycle is examined from the design stage to realize environmentally friendly products and services and environmental consideration is promoted throughout the product realization process. We also collaborate on green procurement with subcontractors, suppliers, and our partners to promote CSR activities throughout the supply chain.
In addition, the Mihara plant is engaged in environmental accident prevention and accident response training, daily equipment inspections and patrols, and planned upgrades to aging equipment, as well as regular cleanup activities around the plant.

Safety and health management (organization and process)

MHIENG’s health and safety management system is divided into "Basic process" and "Project process."

Basic process

The HSE Management Department, a professional organization for safety and health management, is responsible for setting, planning, operating, and evaluating the company's safety and health management objectives, providing governance to each department and project, and providing support.
Through the creation of operational standards, diverse safety and health education programs, and the President's safety awards, we are working to raise the safety awareness of each employee and foster a culture of safety.

Project process

The Construction Department, which carries out safety management at construction sites, cooperates with the HSE Management Department and holds regular meetings to share information on each site. The meetings help maintain high safety standards on all projects.
In addition, HSSE managers (Health, Safety, Security and Environment) are assigned to the construction sites of each project. We will lead daily safety and health activities at construction sites, including advance consideration of safety measures based on risk assessment, on-site safety patrols, and safety instructions at morning meetings.

Safety statistics record

Since the company's founding in 2018, MHIENG has maintained a high safety record at both domestic and international construction sites. Using the industry's standard safety management indicators, TRIR (*01) and LTIR (*02), MHIENG has set a high level of "TRIR: 0.15 or less, LTIR: 0.03 or less" as our goal (*03). MHIENG continues to achieve this goal and in 2021 we achieved zero accidents (0 for both TRIR and LTIR) as a result of the various safety activities we implemented.

  • 01Total Recordable Incident Rate: An index developed by the U.S. Occupational Safety and Health Administration (OSHA) to measure occupational injury safety. Number of Recordable Incidents per 200,000 total working hours
  • 02Lost Time Incident Rate: Number of Lost Time Incidents per 200,000 total working hours
  • 03Goal: MHIENG’s goal is higher than the average safety performance of other companies in the manufacturing and construction industries in Japan and overseas

Activities to raise safety awareness

BBSO(Behavior Based Safety Observation)

At the construction site for each project, MHIENG conducts an all-hands BBSO to foster safety awareness, including the detection of unsafe conditions and behaviors, as well as good cases.

We also focus on disaster prevention activities by conducting STARRT (Safety Task Analysis Risk Reduction Talk: Identify and address prework anxiety conditions), LMRA (Last Minute Risk Assessment) and safety patrols.

Company training

We develop a "Project Safety Education System" for employee safety and health education, including "Safety Leadership Education" for PM (Project Manager) and SM (Site Manager), and operate an e-Learning education program that enables employees to acquire the necessary safety knowledge at each step to become a PM (Project Manager) or SM (Site Manager).
In addition, as part of the Project Safety Education System, the company conducts a monthly "safety e-drill" not only for project workers but also for all employees, including the president, executives, and administrative departments. By repeating the course until they receive a perfect score, each employee continuously improves their safety knowledge and fosters safety awareness.

Safety activities at Mihara plant

The Mihara plant strives to raise safety awareness as follows,

  • holding monthly safety conferences to share the month's safety theme for strengthening safety activities
  • reviewing safety work procedures and ensuring procedures are visual to prevent human errors・implementing daily TBM(*) to remind employees of safety work procedures on the day
  • providing mutual safety supervision by managers and workplace patrols
  • conducting greeting campaigns to promote communication, proposing improvements and reporting medical near-miss incidents
  • Tool Box Meeting : Workplace meeting
