The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

ESG, Sustainability and Impact Jargon Buster

ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

Battery Recycling: Redwood Materials charges towards sustainable innovation

Battery Recycling: Redwood Materials charges towards sustainable innovation

Take a look at how one American company is defining the economic benefits of battery recycling

Battery Recycling: Redwood Materials charges towards sustainable innovation

Founded by Tesla’s former CTO, J.B. Straubel, Redwood Materials is making significant strides in the battery recycling industry with an impressive run rate of 20 gigawatts per year. This capacity is enough to power approximately 250,000 electric vehicles (EVs)—a substantial increase from the industry’s totals just four years ago. Notably, Redwood’s methods not only support recycling at scale but also promise a drastic reduction in carbon emissions by 40-70% compared to traditional recycling processes.

With 95% of battery minerals being recoverable, Redwood is showcasing the profound economic benefits of battery recycling. This approach is crucial as more EV batteries reach their end-of-life, offering a solution that drastically cuts the need for new material mining. Redwood’s initiative is pivotal, especially considering that the EV market’s demand for batteries is only expected to grow as the industry matures.

US currently faces a significant challenge in battery supply chain logistics, primarily dominated by China, which controls about 70% of the world’s lithium refining capacity. Redwood Materials is set to disrupt this dynamic by potentially shifting the centre of battery supply chain operations from China to the US. The company is on track to produce enough recycled battery material to build over 1.3 million EVs annually by 2028, marking a critical turning point for the US in global battery supply chain management.

Redwood’s 300-acre industrial campus exemplifies their commitment to sustainability. The facility operates with zero waste to landfill and all processes are powered electrically, eliminating the need for gas lines. One of the standout features of Redwood’s process is their eco-friendly recycling method, which involves heating materials in a massive kiln at around 300°C without combustion, thus preventing emissions. Remarkably, once the kiln is activated, the process becomes self-sustaining, mimicking a slow, controlled battery fire but without the environmental cost.

Recent studies, including a peer-reviewed analysis by Stanford University researchers, have shown that Redwood’s recycling process could produce up to 80% fewer emissions than traditional supply chains that rely on CO2-emitting refineries. This innovation not only highlights the cost-effectiveness of recycling over mining but also underscores the potential for a sustainable circular economy in battery materials.

In an era where circularity is becoming increasingly necessary, Redwood Materials exemplifies how technological innovation can address sustainability challenges. As the global vehicle fleet shifts towards electricity, the continuous recycling of minerals will reduce the need to extract raw materials, paving the way for a more sustainable and economically viable future in battery production and beyond.
