Crisps Carbon Footprint

Going back a bit to the environmental issues in food processing. Walker crisps in the UK was the first company to do detail work on one of its products.

The illustration indicates that the carbon footprint is calculated up to the point where the packet of crisps is on the supermarket shelf.

The carbon footprint determined in 2007 was 85 g C02. Walkers have achieved a 7% reduction in this to 80 g by:

• Switching to 100% British potatoes to lower food miles
• Training drivers to drive in the most fuel efficient way
• Running our delivery trucks on biodiesel containing 5% used
cooking oil
• Reducing gas and electricity consumption by:
– Improving production line efficiencies
– Introducing new technology – such as low energy lighting
– Educating front-line employees to be more energy-aware
• Reducing the weight of packaging

Why is this of interest to you a food processor who’s clients couldn’t care less? Carbon footprint is almost directly linked to energy which you pay for either directly or indirectly – so reducing your footprint saves cost!

Interesting that even in a process with lots of energy for frying, processing is a small input while farming and packaging represent about two thirds of the footprint.
