Environment – Strengthening Collaboration for Resource Recycling Business

Sharing Case Studies and Technical Data to Strengthen Partnerships and Expand Our Resource Recycling Business

As the world's population increases and living standards in emerging nations improve, it is imperative to use resources more efficiently in order to achieve sustainable growth. This issue requires a global response, as indicated by its inclusion as a flagship initiative of EU 2020, the long term strategy announced by the European Commission in June 2010, and its mention in the Leaders' Declaration adopted at the G7 Summit in Elmau in June 2015.

To reduce input of new resources, the Mitsubishi Electric Group operates a commercial resource recycling business that recovers and reuses resources from our own end-of-life products and refurbishes usable equipment. Under the 8th Environmental Plan (fiscal 2016 to 2018), we share technical data and case studies on a number of businesses internally, and have also started publicizing them externally with the aim of strengthening partnerships in the resource recycling business.


Mitsubishi Electric Group Resource Recycling Business

Engine Replacement for Display Wall System

In 2013, the Mitsubishi Electric Group started operating a service for reusing existing screens and cabinets when replacing projection and drive units. This service not only conserves resources by making use of existing housings, but also improves brightness, extends product life, and contributes to energy savings by upgrading the optical engine.

Existing screen and cabinet are reused, while projection unit and drive circuit are replaced.

"Replace Series" Multi-Unit Air-Conditioning System for Buildings

The Mitsubishi Electric Group introduced the Replace Series multi-unit building air conditioning system in 2005. This system allows existing building air conditioning system pipes to be used as-is. Reusing some pipes without replacement reduces resource inputs, and also delivers energy savings and suitable air conditioning in a shorter installation time.

EleFine Elevator Refurbishment Service

In 2011, the Mitsubishi Electric Group started offering an elevator refurbishment service, replacing the controllers and drive units of existing hydraulic elevators to convert them to traction elevators. This service reduces resource input significantly compared to installing new traction elevators, and also shortens installation time and reduces costs.

Home Appliance Recycling Business (Closed-Loop Plastics Recycling)

The Mitsubishi Electric Group operates closed-loop recycling where we recover plastics from end-of-life home appliances and reuse them in new ones. We have developed technology to sort different types of plastic from a mixture with high accuracy, achieving a massive increase in the rate of recycling from just 6% to 70%.

Rebuild Operations (Reusing Alternators and Starters)

The Mitsubishi Electric Group has been developing their Rebuild Operations since 1979, recovering end-of-life electrical components from automobile manufacturers and making them as good as new. The operations focus on two electrical components: the alternator that supplies power to the vehicle; and the starter that starts the engine. These parts are recovered and disassembled and have only their broken parts replaced, readying them for reuse and contributing to the conservation of resources.

Operations have been conducted mainly in the United States since their inception have in recent years been extended to Japan.

Other

As well as the examples listed above, we also provide services such as refurbishing electrical discharge machines, which are often brought in second-hand, and rewinding generator coils to ensure continued efficiency. Extending product life reduces resource inputs and also satisfies requirements for short delivery times and reduced costs, advantages that will help our resource recycling business to grow.
