Sustainability: Evaluate the process flowchart and identify steps in the process flow below that should be removed or changed to improve environmental sustainability. Explain why you selected each step.

The flowchart covers the steps involved in picking, processing, and packaging and shipping tea. The outline below details these steps at each stage of the process.

1. Farm
   1. Workers pick usable tea leaves from the field
   2. Picked tea leaves are weighed and grouped into 50 kg bags
   3. Bags of weighed tea are moved to a processing area
2. Processing
   1. Bags of tea are reweighed at the processing facility
   2. Tea leaves are spread across pans and troughs
   3. Tea leaves are withered on pans
   4. Tea leaves are cooled
   5. Tea leaved are removed from pans and reweighed
   6. Tea leaves are moved onto special trays and put through a rolling machine
   7. Tea leaves go through their first drying
   8. Tea leaves are cooled
   9. Tea leaves are removed from special rolling trays and put into new trays to go through a second drying machine
   10. Tea leaves are removed from trays and reweighed; poor-quality leaves are thrown away
   11. Tea leaves are visually inspected
   12. Poor-quality leaves are thrown away
   13. Tea leaves are moved to an oxidizing area
   14. Tea leaves are oxidized
   15. Tea leaves go through their final drying to complete the oxidation process
   16. Tea leaves are cooled
   17. Tea leaves are sent to packaging and shipping 
3. Packaging and Shipping
   1. Tea leaves are weighed
   2. Tea leaves go through the first sorting machine; small, misshaped, or discolored tea leaves are discarded
   3. Tea leaves are weighed
   4. Tea leaves go through a second sorting
   5. Tea leaves are put into paper tea bags and sealed
   6. Tea bags are wrapped in paper packets
   7. Tea bags are sealed
   8. Wrapped tea bags are sorted into cardboard packs of 20
   9. Cardboard packs are sealed and wrapped in plastic
   10. Boxes are sorted into shipping boxes
   11. Shipping boxes are wrapped and sealed, ready to be shipped
