How does a Sivakasi match unit work out the carbon footprint of its matchboxes?
Most of the footprint sits in materials, not energy: wood or paper splints, board for boxes, wax and the head chemicals. Weigh each per thousand boxes and apply material factors, then add the unit's electricity and any diesel. Manual units use little power.
Per thousand boxes
- Splints: wood or wax-coated paper, by weight.
- Box board and printed labels.
- Paraffin wax and head composition chemicals.
Energy
Electricity for mechanised lines and drying, plus any genset diesel, divided by output.
