Earth’s ability to regenerate its natural resources is posing significant challenges for the sustainability of our planet.

Repair. Refurbish. Remanufacture. Reuse. Recycle.

Promoting resource efficiency and reducing waste and emissions

Our planet's resources are finite. A circular economy is a must.

Increasing demand, finite resources, unsustainable practices, and environmental impacts is leading to the outpacing of the world’s use of raw materials. In a linear economy, products are designed and manufactured for single-use, with little consideration for their end-of-life disposal.

Promoting resource efficiency, reducing waste and emissions

Linear vs. Circular Economy

In a circular economy, products are designed to be reused, repaired, remanufactured, or recycled, rather than disposed of as waste.

This promotes resource efficiency, reduces waste and emissions, and creates economic opportunities by keeping materials in use for as long as possible.

Product-Life Extension and Value Retention

What are the 5 "Rs" ?


Repair returns a faulty or broken product or component back to a usable state.


Reuse and repurposing entails utilizing or reselling the product for the same or a different application.


Refurbishment improves a product through cosmetic fixes and limited upgrades to functionality.


Remanufacturing restores a used product or a component to as-good-as-when-new or better condition by way of a standardized process in an industrial setting.


Recycling is the recovery of materials and energy contained in end-of-life products.

Minimizing manufacturing's ecological footprint

What is Remanufacturing?

Remanufacturing is the industrial process of returning end-of-service life or aged but valuable assets to same-as-when-new or better condition in a manufacturing environment. This process minimizes the ecological footprint of manufacturing by increasing the useful lifespan of assets and reducing waste.

Remanufacturing is the only approach that provides a full new life to the asset and can potentially enable multiple service lives. Hitachi R&D is deeply committed to creating innovative solutions that accelerate the transition to a circular economy and protect the planet.

Circular economy stakeholders need improved visibility and better access to information

Multiple Stakeholders in a Circular Economy

To achieve circularity, it is essential for multiple stakeholders to collaborate and work towards shared goals. This requires stakeholders to optimize their operations within the broader context of the entire value-chain, rather than solely in their own limited context. To achieve this, stakeholders need improved visibility and access to information from other parts of the value-chain, while also capturing and sharing more information with their counterparts.
