2. The design Process
Discover:
Articulating the CE
opportunity
Every product is different
Define:
Material flows
Feasibility
Interventions
Develop:
Strategies
LCA and other analysis
Business case
Pilots
Deliver:
Implement and role out
Scale

3. Applying the concept to the
built environment:
Elements & Life cycles
Structure to stuff (S.Brand)
Design/Business models
• Service
• Adaptability
• Longevity
• Refurbishment
• Deconstruction

4. A campaign and programme
to raise awareness.
Over 1000 designers
Understand product life cycles
Rethink the design process
from end of life and closed loop
principles
Cradle to cradle

5. Analytical tools
What's in a product
Scarcity
Ethical issues
How easy is it to reuse
recover or recondition

6. A beautiful new connection
across the Tees
stimulate local pride
economic generator
Start with the local

7. Piles made from Old Russian
Gas Pipes found locally in a
yard
Steel components made in a
local steel fabrication yard

8. Zero Waste Scotland
Future of Oil & Gas
Massive decommissioning
£1.8bn per annum
Rigs taken to Spain and Asia
to be smelted
£200 bn: construct
£200 m: decommission
£2m – salvage value

9. How to build a new
industry
Regulation – BEIS targets
100% recycle – 50% reuse
Investment – new ports and
infrastructure
Know-how – deconstruction
to new markets (warranty and
insure), brokerage
New jobs

10. Major Reuse
Government offices
1950s development
Sold for development
Bid won on proposal to
renovate rather than knock
down
L&R were the developer,
Expedition the engineers
.

11. Economic value from
circularity
Cost
Time
Waste
Disruption
Emissions
Carbon

NB. This number specifically relates to lettuce production from
digestate from AD that is converted and used as compost

CE CreditSystem
CommunityToolshed
Citizens are able to easily access
and share local resources, skills
and tools, easing access to one-
time-use items and specialist
knowledge, whilst reducing local
resource consumption as a
whole. This is supported by a
credits system that encourages
participation and exchange.

Sharing Community
Community-owned
infrastructure enables
neighbourhoods to produce,
store and locally distribute their
own energy and resources,
encouraging sustainable energy
production and reducing
reliance on the national grid.
Demand Side Response
A review of previous demand side response trials with a range
of different tariffs (e.g. Time of Use, Critical Peak Pricing)
found that peak energy demand reductions are 60-200%
greater with automation and / or control by other parties (e.g.
suppliers, Distribution Network Operators) than without.

29. CommunityDining
Space-on-demand services,
combined with shared
resources, enables the
community to utilise individual
assets for communal benefit.
