India has committed for carbon neutral by 2070. European Commission has notified Carbon Border Adjustment Mechanism (CBAM) to reduce the carbon emitted during production of raw materials that are imported to Europe. It is necessary to align with these regulations and transit to a low carbon economy to combat climate change. In the two-wheeler automotive sector, the raw material manufacturing stage accounts for 10-12% of the life cycle emissions. Aluminium is the commonly used lightweight material in automotive applications due to its high strength to weight ratio. Virgin aluminium is the preferable choice in automotive applications due to its high purity, consistent quality, and superior mechanical properties. But, production of virgin aluminium is highly energy-intensive, emitting approximately 10-16 tonnes of CO2 per tonne of aluminium produced, yielding it be a major contributor to CO2 emissions during upstream processes. However, secondary aluminium has emission factor less than 2 tonnes of CO2, per tonne of aluminium produced and offers a more sustainable alternative. Use of recycled content in the part production without compromising the quality & property requirements of virgin aluminium enables to offset the emissions from the raw material stage. India has notified a series Extended Producer Responsibility regulations in the recent past. These regulations are enablers for creating an ecosystem for the circular economy in India and thereby increasing the availability of consistent quality secondary aluminium in the upstream supply chain. This paper aims to examine the effect of secondary aluminium in cylinder head application. The study involves the machining response, air tightness requirements, detailed metallurgical and mechanical properties investigation including chemical composition, hardness, microstructure, tensile properties, and casting soundness of aluminium material having exclusive secondary alloys compared with equally proportionated virgin and secondary alloys. The results demonstrate that there was no notable change in the quality of raw material and cylinder head castings by the usage of exclusive secondary aluminium. This reduces the environmental impact by reducing the carbon footprint by approximately 80% of CO2 emission per component and 21,600 tonnes of CO2 annually, and facilitates material conservation, supporting global circular economy goals leading to a more environmentally responsible and resource-efficient automotive industry.
