metal_emissions: Metal Emissions

Description

This function calculates the emissions produced from different metal sources based on the specified inputs. It considers emissions from primary material production and waste disposal of various metal types.

Usage

metal_emissions(
  aluminuim_cans = 0,
  aluminuim_foil = 0,
  mixed_cans = 0,
  scrap = 0,
  steel_cans = 0,
  aluminuim_cans_WD = 0,
  aluminuim_foil_WD = 0,
  mixed_cans_WD = 0,
  scrap_WD = 0,
  steel_cans_WD = 0,
  waste_disposal = c("Closed-loop", "Combustion", "Landfill", "Open-loop"),
  units = c("kg", "tonnes")
)

Value

The function returns the calculated CO2-equivalent emissions as a numeric value in tonnes.

Arguments

aluminuim_cans

Numeric value indicating the weight of aluminum cans. Default is 0.

aluminuim_foil

Numeric value indicating the weight of aluminum foil. Default is 0.

mixed_cans

Numeric value indicating the weight of mixed metal cans. Default is 0.

scrap

Numeric value indicating the weight of metal scrap. Default is 0.

steel_cans

Numeric value indicating the weight of steel cans. Default is 0.

aluminuim_cans_WD

Numeric value indicating the weight of aluminum cans disposed of using waste disposal methods. Default is 0.

aluminuim_foil_WD

Numeric value indicating the weight of aluminum foil disposed of using waste disposal methods. Default is 0.

mixed_cans_WD

Numeric value indicating the weight of mixed metal cans disposed of using waste disposal methods. Default is 0.

scrap_WD

Numeric value indicating the weight of metal scrap disposed of using waste disposal methods. Default is 0.

steel_cans_WD

Numeric value indicating the weight of steel cans disposed of using waste disposal methods. Default is 0.

waste_disposal

Character vector specifying the waste disposal method to use for calculating emissions. Possible values: "Closed-loop", "Combustion", "Landfill", "Open-loop". Default is "Closed-loop". "Open-loop" is the process of recycling material into other products. "Closed-loop" is the process of recycling material back into the same product. "Combustion" energy is recovered from the waste through incineration and subsequent generation of electricity. "Landfill" the product goes to landfill after use.

units

Character vector specifying the units of the emissions output. Possible values: "kg", "tonnes". Default is "kg".

Examples

metal_emissions(aluminuim_cans = 1.4, units = "tonnes")
