Engineering
We provide a one-stop engineering service customized for each client.
Our one-stop service handles everything from startup planning to post-operation maintenance,
inspection, and improvement. With a focus on plant construction, clients get maximum benefit and convenience
at one-stop.
We provide engineering services for plant construction in a wide range of fields, including non-ferrous
metals, chemicals, and pharmaceuticals.
We have staff specializing in machinery, electrical and control, civil engineering and construction, and
process engineering.Our nationwide network of branches and offices will quickly respond to your needs.


Reduce clients' workload
We reduce our clients' workload during new plant construction, reconstruction, and expansion by offering accurate and appropriate proposals for their needs.

Non-Ferrous Metal Plants
From design to construction work, we have a track record of delivery to major smelters
in Japan, including Naoshima Smelter (Mitsubishi Materials Corporation) and Onahama Smelter (Onahama
Smelting and Refining Co., Ltd.). We have extensive know-how in the field.
We also have achievements
with a copper smelting plant in Indonesia.

Industrial Plants
The products that are necessary to achieve a comfortable life in modern society, such as
fuel, synthetic fibers, synthetic rubber, plastic products, chemical fertilizers, pharmaceuticals,
cosmetics, semiconductors, and other products are all produced by chemical engineering. Chemical
engineering is operated in plant facilities with various chemical processes (chemical plants), which must
have stable, safe, and economical operations.
Implementations: Smart materials manufacturing facilities, Compound fertilizers manufacturing facilities,
Sulfuric acid manufacturing facilities, Electronic materials manufacturing facilities, Organic solvent
manufacturing facilities, etc.

Environmental Plants
Inorganic wastewater released from plants and heavy metals (iron, arsenic, copper, lead,
cadmium, etc.) included in mine wastewater cannot be removed at sewage treatment facilities, so separate
treatment facilities are necessary.
We have advanced technologies for mine wastewater treatment facilities and have executed major
construction projects both domestically and internationally.
