Expand circularity and innovate
to avoid and reduce material
waste across the value chain
End-of-life vehicles can generate a large amount
of solid waste, such as car frames, obsolete parts
and tyres. With the rapid growth of EV production in
China, a large number of automotive products will
reach their end-of-life in the near future. In 2023, the
volume of end-of-life batteries in China exceeded
580,000 tons.109 Proper handling and recycling of
vehicle and battery materials can improve resource
use efficiency and bring economic benefits.
Automakers can enhance resource efficiency and
improve recyclability through multiple approaches,
for example: –Product and process innovation: Adopt
practices such as integrated die-casting
and automated manufacturing to improve
resource efficiency. Collaborate with upstream
and downstream partners to design and use
recyclable materials.
–Invest in reuse, remanufacturing and
large-scale recycling: Optimize the recovery
rate and quality of unavoidable production
waste and improve the efficiency of end-of-life
management to achieve high-value recycling.
–Stringent waste management rules: Optimize
manufacturing processes to minimize waste
generation during manufacturing, strictly control
unavoidable waste with authorized suppliers,
especially hazardous waste, and transfer
waste to recycling facilities promptly to avoid
additional pollution.
Partnership for non-downgrading circular use of aluminium BOX 5
Currently, about 80% of aluminium can be recycled
in China.110 More than 90% of recyclable aluminium
is used in a downgraded way, however.111
Improving the quality of recycled aluminium – while
simultaneously creating opportunities for innovation
and new business ventures – is one of the major
challenges facing the industry in China.
To enhance the efficiency and automation of scrap
metal recycling and produce high-quality recycled
aluminium, China Hongqiao Group partnered
with Scholz, an automobile dismantling and metal
recycling enterprise in Germany. This joint project
harnesses Scholz’s advanced scrap automobile
dismantling capabilities and recycled-aluminium
production technologies, ensuring that recycled
aluminium can be used without degradation.
Meanwhile, it integrates end-of-life motor vehicle
recycling and dismantling, aluminium recycling and power battery recycling, with the aim of
feeding the materials back into manufacturing in
a closed loop.
This initiative helps to reduce the demand for
primary aluminium and cut costs, and integrates
dozens of companies in the upstream and
downstream industrial chain of end-of-life motor
vehicles, power battery recycling and aluminium
scrap recycling.112 Upon completion, the joint project
is estimated to have an annual production capacity
of 500,000 tons of recycled aluminium, with a
95% reduction of energy consumption and 85%
reduction of carbon emission per ton compared with
non-recycled aluminium.113 It’s additionally expected
to have an annual recycling and dismantling
capacity of 100,000 scrap motor vehicles and an
output value of more than CNY 10 billion (Chinese
yuan) (approximately $1.4 billion).114
