What are the benefits of recycling end-of-life electric motors?

In today’s era of rapid development in new energy, the scrap motor recycling industry is quietly emerging as a new venture opportunity. According to incomplete statistics, the total volume of scrap motors generated globally each year exceeds 80 million tonnes. These contain large quantities of recyclable rare materials, such as copper, aluminium and rare earth elements. The recycling of end-of-life electric motors offers both environmental benefits and economic value.

The Environmental Significance of Motor Recycling

1. Reducing Environmental Pollution

Scrap motors contain many harmful substances, such as heavy metals including lead and mercury. If these substances are not properly treated, they can cause severe pollution to soil, water sources and the atmosphere, thereby endangering human health and the ecological environment. By subjecting scrap motors to safe and non-hazardous treatment to prevent the release of these substances during the recycling process, environmental pollution can be minimised.

2. Conservation of Resources

Motors contain large quantities of renewable resources, such as metals and plastics. By using specialised motor recycling machine to extract valuable metallic materials—such as copper and aluminium—these can be reprocessed and reused. This not only reduces the demand for virgin resources but also minimises the damage caused by the excessive extraction and processing of such resources.

3. Promoting a Circular Economy

Through the recycling and reuse of end-of-life electric motors, resources can be reused and waste generation reduced. This drives the transition of the entire equipment sector towards a circular economy model. Not only does this help to reduce resource wastage, but it also lowers the energy consumption involved in manufacturing new electric motors and reducing the extraction of raw materials.
 

The Economic Value of Motor Recycling

1. Substantial Recycling Profits

Recycling metal resources from motors, such as copper and aluminium, allows them to be reintroduced into the market following processing. This reduces reliance on virgin metals and cuts production costs. For example, copper accounts for approximately 8 per cent of a motor’s composition. The current price of copper is around US$11,000 per tonne. Consequently, the profit margin per tonne of recycled scrap motors is very high.

2. Improved Resource Utilisation

Through motor recycling, components from end-of-life motors can be dismantled and carefully sorted, making them reusable as motor parts. This not only extends the service life of motors but also improves resource utilisation, thereby reducing the raw materials required to manufacture new motors.
