What is green aluminum?
I repeated many efforts to meet the request of the customer by the Kaimei copper elongation until now.
In addition, I perform various approaches for contribution to decarburization society to support global warming based on "aluminum VISION2050" which Japan Aluminium Association announced (the next q.v.) and realization of the sustainable society.
I introduce the green aluminum which is one of the approaches of the inside here.

CO2 load as materials of aluminum
The reduction of the quantity of CO2 exhausted by aluminum Shinchi gold smelting becomes the problem while attention gathers in the carbon neutral for decarburization society, realization of the sustainable society
The CO2 load (kg-CO2/kg) accompanied with the aluminum Shinchi gold production is considered to be 9.24 and is bigger than 2.25 of iron
The CO2 discharge when it produces 1 ton of aluminum Shinchi iron is 9.24 tons
The specific gravity of iron is about 3 times of the aluminum, but is only about 1/4 with the CO2 discharge
The specific gravity of iron is about 3 times of the aluminum, but is only about 1/4 with the CO2 discharge
The metal weight to use by using aluminum in substitution for iron increases the CO2 load while it decreases
The source: The AI investigation
It is said that I exhaust at least 2 tons of CO2 per 1 ton of aluminum in any laboratory except a power source at the time of the smelting by the aluminum smelting
A reduction reaction: Al2O3 + 3/2C➡2Al +3/CO2 = 1.5 tons
Others ：= 0.5 tons such as cryolite fusion
In addition, it is said that a CO2 discharge derived from a power source at the time of the smelting is added, and about 9 tons of total CO2 per 1 ton of aluminum is exhausted
To lower the CO2 load at the time of the aluminum smelting
I use the money of aluminum Shinchi smelted from a generation method with the big fossil-based fuel of the environmental load by a generation method by the renewable energy (energy derived from = nature) or attention gathers to "the green aluminum" from the utilization of recycling materials
There is not the clear definition, but a thing less than 4 tons of CO2 discharges is often referred to with Scope1 in a supply chain discharge, 2, and a power source is often recognized as "green aluminum" about a thing of the renewable energy about "green aluminum" at smelting
What is a supply chain discharge?
As well as discharge of company oneself, I point to the discharge that added up every discharge to be related to operation. In other words, it is a greenhouse gas discharge to occur from the whole a series of flows including raw materials procurement, production, distribution, sale, the disposal
Supply chain discharge = Scope1 discharge +Scope2 discharge +Scope3 discharge
In the Scope3 standard of the GHG protocol, I classify Scope3 in 15 categories

Generation method to be used at the time of aluminum smelting
Among aluminum smelted throughout the world at at 2020, 70% or more are prepared by coal, a generation method by the non-reproduction energy such as the gas
A ratio smelted by a generation method by the renewable energy is only a little less than 30%
→ Waterpower: 27%, others 2%
Generation method by the renewable energy
What is renewable energy? ・Definition * in ・ ・ ... law
"The thing that it is permanently admitted that it is available as an energy source in non-fossil energy sources"
＊Law → "A law about the promotion of the use of the non-fossil energy source by the energy supply company and the effective use of fossil energy sources" and "the enforcement order"
[concrete type of the renewable energy]
In 1 sunlight 2 wind power 3 waterpower 4 terrestrial heat 5 solar heat 6 atmosphere other naturally occurring heat 7 biomass (organic matter derived from the animals and plants)
The green aluminum which our group provides
The green aluminum which our group provides adopts Middle Eastern UAE (the United Arab Emirates) EGA company (Emirates Global Aluminium) [brand name] CelestiAL
The green aluminum of EGA company lowers CO2 load by smelting sunlight as a power source. I exhaust about 9 tons of CO2 per 1 ton of aluminum by the generation method by the non-reproduction energy, but say that the CO2 discharge is reduced by the calculation of EGA company in about 9 tons of ➡ about 3-4 tons by photovoltaic power generation
The source: Our supplier investigation
I place the decarbonization of the industry as the most important problem as EGA company, and one of the world's largest green starts becoming it. Plan to achieve CO2 discharge net zero by 2050
