Brewing - emissions and waste

Efficient packaging

Investigate the possibility of "lightweighting" bottles by redesign

• narrow neck press and blow (NNPB) in glass bottle manufacture
  • enables more even wall thickness

Lighter cans may be appropriate

Work with suppliers to maximise recycling efficiency

Lightweighting of secondary and tertiary packages

Recycle packaging waste

• minimise waste by maximising packaging line efficiency
  • minimising processing faults

Diageo lightweighted their bottle caps from 2.1 g to 2.0 g without a loss in product quality of freshness. This seemingly small change mulitplied across Diageo's whole business has resulted in a reduction of 100 tonnes of steel and environmental benefits.
