Together with the Global Environment

Environmental management

Basic concept

Realizing a sustainable society that harmonizes with the global environment is a pressing issue that is shared by humankind. In particular, companies that create a large environmental load have the responsibility to actively tackle environmental problems.
Based on this recognition, at Murakami, we have drawn up an “Environmental Policy” and obtained ISO14001 certification. We are carrying out initiatives that are kind to the environment through our general business activities, such as research and development, manufacturing, sales and distribution.

Environmental policy

We strive for a reduction of environmental load in terms of the development, manufacturing and sales activities of photosensitive materials, screen masks as well as screen printing equipment and materials in our screen printing business, and we aim towards the symbiosis of our business and the protection of the global environment.

  1. We aim for continuous improvement by working to prevent environmental pollution around the local region, reducing industrial waste, saving energy, saving resources as well as conducting green procurement and, furthermore, by developing new products that take environmental impact into consideration.
  2. We adhere to matters determined by the organization, not to say in the least comply with environmental laws and regulations as well as regulations formed by regional governments.
  3. We specify our environmental purposes and goals, implement them according to a plan, and conduct a review.
  4. We endeavor to raise environmental awareness by providing appropriate environmental information to all parties involved in the business and by carrying out education and training.
  5. We aim to coexist with the global environment, such as the local community, by providing information including our environmental policy to the general public according to our rules and regulations.

Environmental management system

In order to implement a corporate management that takes the environment into consideration, at Murakami we are actively promoting the acquisition of ISO14001 certification, which is an international standard of environmental management system. After the initial registration in December 2004, we expanded the scope of operations and business offices, and we obtained certification for all business offices in December 2017.

Products taking the environment into consideration

Basic concept

At Murakami, we aim to contribute to the reduction of environmental load to customer companies and to society by focusing on the development and manufacture of environmentally-conscious products and striving to spread these products through active dissemination of information.

Bichromic acid-free photosensitive material, REX series

Although in the past bichromic acids such as hexavalent chromium were used in photosensitive materials for screen printing, at Murakami, we gave consideration to the impact it would have on the environment and the human body and thus made efforts to develop a photosensitive material that does not use bichromic acids. As a result, in 2003, we developed the bichromic acid-free photosensitive material, REX Series. Demand for the REX Series is growing across the globe, particularly in Southeast Asia where there is an expanding market for textile printing using rotary screen printing.
The REX Series also has high-sensitivity and high-resolution patterning characteristics, which could not be reproduced with the conventional photosensitive materials that used bichromic acids, and they are also suitable for high-resolution plate making with a DLE exposure device.

Development of applications for water developed photopolymers

In screen printing, plate making is performed by exposing and developing a pattern to be printed on a photosensitive material coated over a screen. In the past, organic solvents and alkali aqueous solutions were used in the development process; however, with an aim towards reducing environmental load, photosensitive materials (photopolymers) that are developable in neutral water are now in demand.
At Murakami, we have responded to these needs by developing photopolymers that are developable in neutral water, and we have also realized their patterning on base materials that are weak against organic solvents and alkali aqueous solutions. Furthermore, we are currently carrying out research to develop applications for the technologies that we have accumulated in this process to areas other than screen printing such as cosmetic materials.

Reduction of environmental load

Cutting down CO2 emissions

At Murakami, we are working to cut down our CO2 emissions, which occur as a byproduct of our business activities, in order to contribute to the suppression of global warming. In addition to taking steps to understand and analyze the amount of emission at each location, we are driving forward initiatives towards the achievement of reduction goals that we have set for the entire company.

Environmental contribution through solar cells

Screen printing is utilized for the formation of solar cell electrodes, and it contributes to high productivity and cost reduction by improving the print precision through high-quality screen masks.
When the production volume of PV panels using solar cell faceplates manufactured by the entire Murakami Group is converted to the amount of CO2 reduction, it will be a reduction amount of over 2 million tons in a year. This is comparable to the amount of CO2 absorbed annually by a forest* with a square measure equivalent to about 1.17 times of the area of Tokyo.

Understanding and analyzing the amount of emissionUnderstanding and analyzing the amount of emission

Waste reduction

At Murakami, we are taking action towards achieving the goals we have specified for each office location in terms of the reduction of the generated amount and final disposed amount of wastes as a consequence of business activities.

Management of chemicals

Regulations of chemicals that have an impact on the environment and human body is being reinforced, such as through the RoHS Directive*1 and REACH regulation*2. In order to appropriately meet such requirements, at Murakami we conduct sales based on a rigorous check of chemicals in regards to not only products that we self-produce but also other companies’ products.

*1 RoHS Directive: EU directive on the restriction of the use of certain hazardous substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ethers) in the manufacturing steps of electrical and electronic equipment.

*2 REACH regulation: EU regulation on the overall registration, evaluation, authorization and restriction of chemicals

Promotion of environmental education

To enable all employees of the Murakami Group to carry out activities with a high level of awareness towards the global environment, we implement environmental education including a course on environmental management systems. Furthermore, we conduct an emergency countermeasures education in a planned manner so that quick and accurate actions can be taken should an environmental accident occur by any chance.
