6. Caring for the Environment
6
PUBLIC
Northern Powergrid are committedto promoting environmental
protection, best practice, and legal compliance amongst all staff.
We take our environmental responsibilities seriously and have
developed targets and objectives to help manage the environmental
impact of our activities. These include;
 Water and land pollution,
 Waste recycling,
 The impact of noise and visual amenity,
 The care of local wildlife & ecosystems,and
 Our carbon footprint.

7. Strategy Development

Some Key Objectives
•Reduce fluid
loss by 15%
•Reduce our business
carbon footprint by
10%
•Reduce noise and
visual amenity
•Minimise sulphur
hexafluoride(SF6)
losses
•Underground

8. Waste Strategy

Creating a wastestrategy is key to delivering some of our objectives…

9. What About Energy?
9
PUBLIC
But, how can a waste strategy effectenergy cost or use?
Think about it like this –
If products are manufactured using recycled materials, then the need for virgin
materials is reduced along with the resulting energy required to extract and
process them in the first place.
Although the amount of energy saved by recycling will vary depending on the
type and volume of material recycled, almost all recycling processes will save
significant amounts of energy when compared againstprocesses that use virgin
materials.

10. Putting it in Context
10
PUBLIC
An example that is widely cited is the recycling of aluminium drink cans:
When you recycle aluminium drink cans, you save 95% of the energy required to
make the same amount of aluminium from its virgin source, bauxite.
So, by recycling just one tonne of aluminium drink cans, you conserve more
than 207 million Btu - which is the equivalent of 36 barrels of oil or roughly
1,665 gallons of diesel (7,559 litres).
PS – In case you are wondering, you’ll need around 60,000 drink cans to make
one tonne!

11. Understanding Waste
11
PUBLIC
So, what if you don’t happen to have 60,000 used drink cans lying around…
We didn’t, so we had to determine what our waste streams and volumes were;
• We asked simple questions – Who, What, When, Where, Why and How with
regard to all of our wastestreams.
• Then we cross referenced these to things we could do with waste, such as
create it, store it, transport it, reduce it, recycle it, reuse it, dispose of it and
so on.

12. Understanding Waste
12
PUBLIC
We reviewed this data againstsome base parameters:
• We wanted to keep all resources in use for as long as possible so we could
extract maximum value from them before having to do something
alternative with them.
• Once the materials were at the end of their useful life we wanted to recover
or regenerate the materials where we could, somehow.
• Once all known alternatives were exhausted (within economic limits) then,
and only then, we would accept landfill as the wastes final fate.

13. Making Diversity Work
13
PUBLIC
Integrated waste managementinvolves a mix of several waste management
approaches, depending upon the prevailing economic and environmental
conditions – including source reduction, incineration, composting, recycling, re-
use and ultimately landfill.
• As our waste was diverse in terms of number of waste streams and volumes
(largely outside of our control) we opted to use an integrated waste
managementapproach for each of our waste streams so they could be
managed individually rather than as a group. See Over...

16. It Doesn’t Stop There!
16
PUBLIC
Whilst we do the upfront segregationand management of waste on site, that
isn’t quite the end of its journey.
• As with many organisations our office and black bag type waste go to MRF
facilities for detailedsorting and recoveryoff site.
So at that point it seems appropriate for me to hand you over to Ethan who
can tell you more about this...

17. ‘No Waste from Waste’
Controlling energy costs through waste strategies

18. A UNIQUE OPERATION ON THE RIVER THAMES
160,000 homes powered
1 million tonnes of waste
and aggregate
Serving London for
over 120 years

19. • Reinforce our river heritage and
low carbon route for the transport
of waste and bulk materials
• Committed to enabling recycling
• Generating energyand materials
from truly residual waste
• No waste from waste - no waste
to landfill or exported
OUR VISION

20. • Resource productivity and energy efficiency are at the heart of our
operations
ENERGY FROM WASTEAND RESOURCE PRODUCTIVITY
• Up to 250k tonnes of ash
recycled as construction
aggregate
• Used to widen 5 junctions of M25
motorway
• Up to 10k tonnes of Air Pollution
Control Residue creates building
blocks
• Certified as carbon negative
bricks – take carbon out of air

21. SUSTAINABILITY IN PRACTICE
INSIGHTS

22. INSIGHT 1: Build on historical successes.
• Industry leading track record of using
systems to successfully manage health,
safety and environment
 Structured approach
 Philosophy is continuousimprovement
• Workingtowards international best
practice standard for energy management
– ISO 50001
SUSTAINABILITY IN PRACTICE

23. INSIGHT 2: Keep the measurement and message simple.
SUSTAINABILITY IN PRACTICE
Our holistic solution
• 200 kg of carbon saved per tonne of waste
vs landfill
• 9 times the amount of energy generated per
tonne of waste vs landfill
• 100,000 lorry movements avoided due to
use of the river
See: http://www.coryenergy.com/carbon-efficiency/less-carbon/

24. INSIGHT 3: Message becomes the mission.
• Sustainability goals become aligned with the overarching mission:
SUSTAINABILITY IN PRACTICE
Sustainability Goals Our Mission

• Driving resource productivity
• Maximising generation of energy and
recycled by-products
• Sustainable growth

25. INSIGHT 4: Focus on always being better.

Questions & Comments

29. Waste and energy challenge us to think outside the box’.
1. How can energy managers keep driving change and continue to be
better?
 Achieve business clarity on direction of travel by getting message right;
 Framing resource and energy productivity as strategically important,linked to increase business
productivity,growth and competitive advantage;
 Don’t be afraid to fail;
 Collaboration – solutions are decentralised across sectors;
 Holding policy-makers to account.Both industry and governmenthave a role to play.
• 2. How do you drive behavioural change?
– Answer – Reinforcement,communication,morecommunication,change style of communication,reward and
encouragement,demonstrate benefits – sell,sell up and add on.
• 3. What are the barriers associated with implementing a waste strategy?
– Answer – Current contracts,procurement or operations strategy not aligned with waste strategy,cost,
executive buy-in,service provider limitations.
• 4. How do you bring a business case to life?
– Answer –Try to get buy-in,put the business case into different terms. Don’t try to make waste sexy,
demonstrate other‘sexier’benefits (safety, operational,financial etc.),use data to tell the story,link to other
businesses success stories.
