We're improving the environmental profile of Wrigley Operations by:
- Reducing energy, greenhouse gases, water, and waste
- Identifying more efficient transportation options
- Leveraging high performance design to create new facilities and update existing facilities/processes
- Ensuring sustainable practices among external manufacturing partners
We seek to continuously improve our environmental performance, including energy use, water use and discharges, waste generation, recycling/reuse, and greenhouse gas emissions. There have been some great successes:
FDF case study: Effluent Wrigley UK has successfully implemented a scheme to convert waste water into green electricity at its site in Plymouth.
Previously, effluent from the factory comprising of water and syrup, from washing out production equipment was drained away. In May 2006 Wrigley established a new process enabling the effluent discharge to be taken off site in tankers to be used as feed stock for a local biogas plant where it is recycled to generate green electricity.
The by-product from the conversion into green electricity is then used as a natural fertilizer for local farmers. In 2007 this amounted to 2.708 tonnes of waste diverted from drains. Overall, since the scheme began the Wrigley company has diverted 15,856 tonnes of effluent from drains.
This scheme not only reduces waste water significantly, it also makes a positive contribution in offsetting CO2 by the production of green electricity as well as supporting local community needs in its use as a natural fertiliser.
Hubba Bubba case study: Clam shells
Wrigley UK identified from recent study that relative impact of miles travelled by inbound raw materials accounts for around 72% of total Carbon Footprint for the UK (whilst this accounts for 52% for the West region).
The plastic containers ('clam shells') used for production of the Hubba Bubba bubble tape product were identified by Wrigley as a high impact product in terms of inbound food miles. Based on this insight, Wrigley UK has moved sourcing from the US to Europe significantly reducing the impact.
Moving clam shell sourcing to the UK has reduced share of food miles from 29% to 4%. Further improvements are being made as further sourcing requirements are moved from EU to UK in 2009 including:
• Up to 25% reduction in packaging weight on key SKUs
• 25% reduction in pellet bottle plastic from 16g to 12g per unit
• Blister Alufoil weight reduction by 25 %
• Blister Sleeves: move to recycled paperboard
• 10% weight reduction for Blister Film
• 7% weight reduction of the current inner wrap
• All outer trays on recycled board
• Mints Flow wrap move from metallic/printed film to clear film
• Handy Box paperboard weight and paperboard optimisation
In 2008 Wrigley was proud to achieve the ISO14001 accreditation; an internationally accepted standard approving the management of any impacts of its factory on the environment.
