The Greenhouse gas (GHG) neutrality has become an important issue at stake for consumer industries as well as basic industries. Manufacturers of consumer products demand for carbon neutral intermediates to be able to communicate carbon neutrality of their products. One example is the car industry that increasingly urges the aluminium producers to supply "carbon neutral" aluminium which directly effects upstream suppliers in their production.
One of these upstream suppliers is the Rain Carbon Group providing Calcinated Petrol Coke (CPC) in its petrol coke calcination Business Unit with facilities located in Europe, USA and India. CPC forms the main component of anodes used for aluminium electrolysis.
In a study commissioned by Rain Carbon GmbH, the scientists identified a couple of options to reduce GHG emission that could help the company to derive the basic lines of a corporate strategy towards greenhouse gas (GHG) reductions and to create a vision towards GHG neutrality.
Thereby a difference was made between Rain Carbon's own operations (the calcination process) and the associated upstream and downstream production processes that are not directly in the company's hands (both the upstream production of Green Petrol Coke (GPC) in refineries and further downstream processing the CPC into anodes and their burn-up during aluminium electrolysis). As the discussed options would occur on different time scales, the authors recommend developing a roadmap that combines both mid-term and long-term pathways to a consistent strategy towards climate-neutral CPC along the entire value chain.
