SinterCast contributes to the environment directly and indirectly. In the foundry, the improved efficiency of the SinterCast-CGI technology reduces energy consumption; reduces CO2 emissions; and reduces the demand for raw materials. On the road, CGI enables the use of more efficient downsized engines, improving fuel economy and reducing CO2 emissions. Scroll down to learn more about how the SinterCast technology contributes to the environment: in the foundry; in passenger vehicles; in commercial vehicles; in clean diesel engines; and in life cycle analyses compared to aluminium engines and electric vehicles.
In the foundry, the improved efficiency of the CGI casting process provides energy savings and reduced CO2 emissions. More than 90% of the raw materials used to produce CGI come from recycled sources.
Right First Time
- Improved process control reduces energy consumption and CO2 emissions.
- Reduced scrap rates mean fewer castings need to be re-melted and re-cast.
- The energy needed to melt cast iron: ~10,000 MJ / tonne.
- Annual energy demand for a foundry producing one million Engine Equivalents per year, with a mould yield of 65%: 800 million MJ.
- Every 1% of scrap reduction, 1% of weight reduction or 1% of improved mould yield saves 8 MJ – approximately 400 tonnes of CO2 for every one million Equivalents.
- SinterCast contributes to the environment by improving process efficiency, helping foundries to be right-first-time.
- The increased strength and stiffness of CGI allows engine engineers to reduce 10-20% weight compared to conventional grey iron designs.
- Less weight means less metal melted, less energy consumed and less CO2 emissions from the foundry.
- 15% weight reduction provides an annual savings of 7,500 tonnes of castings, and approximately 10,000 tonnes of liquid iron for every one million Engine Equivalents.
- The reduced liquid metal demand corresponds to a saving of approximately 100 million MJ of electricity and 500 tonnes of CO2 per year.
- SinterCast contributes to the environment by enabling the reliable high-volume production of CGI; and enabling weight reduction of critical components such as cylinder blocks and heads.
On the road, CGI enables the use of more efficient downsized engines, providing higher fuel economy and lower CO2 emissions.
- The higher strength and stiffness of CGI allows engineers to reduce weight while increasing combustion pressure, resulting in more power per litre.
- Smaller CGI engines can replace larger engines while providing similar performance.
- CGI downsizing can provide weight reduction of approximately 25 kg in a passenger vehicle.
- Every 100 kg of weight reduction provides a fuel saving of approximately 0.2 litres for every 100 km driven.
- 25 kg weight saving corresponds to approximately 100 litres of saved fuel over the 200,000 km lifetime of a vehicle, providing a reduction of approximately 250 kg of CO2 per vehicle.
- SinterCast-CGI diesel engines provide 20~30% improved fuel economy and 20~30% less CO2 compared to the nearest available petrol engine option.
- Weight reduction in commercial vehicles enables increased payloads, educed vehicle-miles and improved fuel economy.
- Every 100 kg of weight reduction improves fuel economy by approximately 0.1%.
- For a typical 12L engine, with fuel consumption of 40 litres per 100 km, SinterCast-CGI can reduce weight by approximately 100 kg.
- Weight reduction of 100 kg can yield fuel savings of approximately 0.04 litres for every 100 km.
- For annual mileage of 250,000 km, 100 kg of weight saving in a fleet of 100 trucks corresponds to a fuel saving of approximately 10,000 litres of diesel fuel per year – a reduction of more than 25 tonnes of CO2 per year for the fleet.
