Sustainability

Together with our customers we raise circular efficiency, reduce emissions and develop advanced industrial parts that withstand the extreme demands of the energy transition.

STRATEGY & EXECUTION

Solar-based energy transition

We are using the factory roof and unused land for photovoltaic and solar thermal installations, moving toward supplying part of the electricity and heat used in machining ourselves. [Installed capacity and the rollout schedule will be published once confirmed.]

Rooftop solar power

Photovoltaic modules on unused roof area supply daytime operating power ourselves.

Solar thermal process preheating

Heat transfer fluid warmed by solar collectors feeds the preheating stage of cleaning and drying processes, reducing gas consumption.

Real-time generation management

We collect inverter data to manage generation and self-consumption rates, and detect equipment faults early.

Operating the photovoltaic installation

[In preparation] To be published once the photovoltaic capacity and self-consumption rate of the production facility are confirmed.

RENEWABLE ENERGY

What solar changes

We are bringing solar onto the production floor along three lines: generation, heat supply and operational management.

Rooftop solar power

Photovoltaic modules on the factory roof and unused land supply daytime operating power ourselves. Surplus power is

exported to the grid, lowering annual electricity costs.

Solar thermal process preheating

Heat transfer fluid warmed by solar collectors feeds the preheating stage of cleaning and drying processes.

Sintering and heat treatment, which need high temperature, stay on existing plant; only the low-temperature range is replaced with solar heat.

Equipment operation and inspection

We monitor generation and self-consumption

continuously, catching module soiling, shading and

inverter faults early. The cleaning interval is set from seasonal generation

data.

Why solar

Machining refractory metals uses a lot of electricity

and heat. There is a limit to how far consumption can be cut, so where that energy comes from is what governs emissions.

Machining refractory metals uses a lot of electricity and heat. There is a limit to how far consumption can be cut, so where that energy comes from is what governs emissions.

Photovoltaic generation hours overlap with operating hours, which helps raise the self-consumption rate, and there is considerable room to replace low-temperature heat with solar thermal collection. That is why we are applying both together.

STRATEGY FRAMEWORK

Core pillars of sustainability

Our long-term value creation is organized around three core environmental and corporate pillars that address both our internal carbon footprint and our value chain impact.

Core pillars

Responsible management

We hold ourselves and our partners to high standards through strict compliance, high safety standards, fair labor practices and transparent human rights indicators.

Zero-accident goal

[Supply chain management target to be confirmed]

An inclusive and diverse workplace

Working with materials comes down to people in the end. On a floor with high temperatures and heavy material, everyone finishing the day unhurt, and machining skill built up over years passing to the next generation — those two things are where the responsibility Korea Tungsten speaks of begins.

A responsible employer

Safety first

We start from the premise that every accident can be prevented. We assess the hazards of high-temperature furnace, press and heavy-material handling processes regularly, and draw up and carry out improvement plans for each site.

Passing on the craft

Skill in machining hard-to-machine metals accumulates in people, not in equipment. We run an in-house training system so that the know-how of experienced staff carries on through records and teaching.

Fair opportunity

We provide equal opportunity regardless of nationality, gender or age, and aim for a culture where people can voice their views safely.

Ethics and human rights

We treat legal compliance as the minimum standard and apply internationally recognized human rights principles across our own operations and our dealings with suppliers.

With our community

As a member of the community our plant sits in, we take responsibility for local hiring and environmental management.
