How Is BYD Driving Its Sustainability Strategy?

Chinese electric vehicle manufacturer BYD, which began as a battery production company, has expanded its operations to become a global player in sustainable energy technologies.

BYD’s business strategy is closely aligned with its sustainability initiatives, which could help contribute to global emission reduction targets.

Its mission to “cool the earth by 1°C” underpins its sustainability goals. Central to this is BYD's objective to achieve carbon neutrality across its entire value chain by 2045.

A medium-term target is a 50% reduction in the carbon intensity of its own operations by 2030, using 2023 as a baseline.

Since its founding in 1995, BYD reports it has removed more than 16 million tonnes of carbon emissions globally.

BYD's Blade Battery and the circular economy

Powering each of BYD’s electric cars is its Blade Battery. It is noted for its low-temperature performance and longevity.

The battery is designed to last for more than 15,000 charge and discharge cycles, which exceeds the typical lifespan of a vehicle.

This design allows for the batteries to be recycled for use in energy storage or low-speed EVs at their end-of-life.

This process contributes towards a circular economy by maximising the use of resources.

The cell arrangement within the Blade Battery follows a honeycomb-like structure, which optimises the battery's strength and enables it to withstand high levels of force.

The manufacturing process for the battery also reduces the reliance on scarce resources such as nickel and cobalt.

This approach could lessen the ecological damage associated with certain mining techniques.

Optimising packaging and industrial waste

An example of BYD’s sustainability work can be seen in a package material optimisation project at its base in Thailand.

The facility generates a significant amount of industrial waste from materials like plywood, iron frames and rust-proof bags that are not recyclable.

In response, BYD is aiming to optimise its packaging system by transitioning to recycled steel boxes.

A dedicated package recycling team will sort materials for reuse after delivery. This change is intended to reduce the facility's dependence on disposable packaging and lower both production and disposal costs.

According to BYD, BYD expects this initiative will reduce the amount of industrial waste generated at its Thailand base by approximately 30-60%.

Zhao Jianping, Chief Sustainability Officer for BYD, says: “BYD is deeply involved in the field of new energy and has been committed to green and sustainable development since its establishment. Along the way, BYD has been constantly thinking and practising, moving forward steadily on the road of paying attention to the destiny of mankind and improving the well-being of relevant parties, and continuously contributing to global sustainable development.”

Wastewater management and regulatory compliance

BYD is also implementing efficient wastewater management systems throughout its facilities. BYD’s wastewater is classified and treated based on its source and nature.

Industrial wastewater is collected and handled by the facility’s internal treatment system, while domestic wastewater is processed through septic tanks before being discharged in compliance with local standards.

The treatment stations at BYD’s main operating sites employ processes that include coagulation precipitation, dissolved air flotation and phosphorus removal.

Key metrics such as pH levels, chemical oxygen demand, and ammonia and nitrogen content are monitored to align with pollution control measures.

BYD has also developed an online monitoring system to track wastewater discharge and encourages third-party inspections to improve water quality and ensure its wastewater discharge complies with national laws and regulations.
