Opticup Carbon Footprint

deSter

The Opticup and standard cup have a different product carbon footprint, whereby the Opticup has less CO2 emissions. In the table below 50 000 cups of both types are compared, both assumed to have 10 reuse cycles. The carbon footprint in this report is calculated according to the standards and guidlines of the Greenhouse Gas (GHG) protocol. Boundary of the calculation is cradle-to-grave, which means full life cycle assessment from resource extraction (‘cradle’) to the use phase and disposal phase (‘grave’). Below you can find the assumptions and sources of this comparison explained.

Assumption and sources of calculation above:
In this comparison of the carbon footprint, 50 000 Opticups and 50 000 RAFC cups are compared, both assumed to have 10 reuses, after which they get disposed. 
Both cups are made in polypropelyne material, assumed from the same supplier and the raw materials is transported via road.
Cups are packed in sleeves and carton boxes, also accounted for here.
Assumed is 500 km transport to a customer, by road.
Emissions of washing are also considered and based upon ecoinvent data, together with data from an industrial cleaning line of the brand Meiko.
For the end-of-life of the cups and packaging, European waste treatment rates are used (2020 data) to estimate the disposal: 39,9% recycled – 19,2% incinerated with energy recovery – 40,9% lanfilled.

Emission factors used for these sources:
Raw materials = ecoinvent, 2020
Transport = UK DEFRA
Electricity for production = European Residual Mixes 2018
Washing = ecoinvent, 2019
End-of-life = ecoinvent 2020

Cradle-to-gate:

  • Raw materials
  • Transport to production site
  • Production of final product
  • Transport to customer

Cradle-to-grave:

  • Raw materials
  • Transport to production site
  • Production of final product
  • Transport to customer
  • Transport to end of life management
  • End of life product: waste or reproduction
