Regression analysis: Simple Linear Regression Multiple Linear Regression
Blake Lapthorn green breakfast seminar - Waste Or Resource
1. Waste - or
Resource?
James Astor
17th March 2010
2. Agenda
• Introduction
• Linking UK waste strategy with:
– Energy security
– Climate Change
• Regulatory drivers
• Recycling technologies
• Case study: Oxfordshire
3. Agrivert
• Recycling organic material for 17 years
• Designed & built 11 recycling sites between 2002-2008
– in 2008 these sites recycled over 300,000 tonnes organic material
– spread product over 30,000 acres
– Relationships with over 200 farmers
4. Energy security
• North Sea gas reserves in decline
• “Dirty” coal fired power stations
being decommissioning
• Remaining Magnox nuclear stations
closed by 2015
5. Project Discovery
• Ofgem’s investigation into future security
of supply from existing market
arrangements over the coming decade
• Verdict: Lights may go out in 2015
• Impact: Drive for more local generation
capacity, independent of imports
6. Climate change
The world is warming up
because of the increase
in GHG emissions
This is bad
There is no international
consensus on what to do
about it
That is bad too
7. CC and the EU
• Some steps agreed to reduce GHG emissions
within the EU
• Regulation introduced to drive:
– Greater energy efficiency
– Greener energy generation:
• Electricity
• Heat Focus on
• Transport renewables
More embedded
power
8. CC and organic waste
• Organic waste in landfill generates
methane as it decomposes
• Methane is a very powerful greenhouse
gas
• To reduce overall emissions, reduce the
amount of organic waste in landfill
9. UK organic waste levels
Million tonnes Municipal Commercial Total
and Industrial
Kitchen/food 6.1 5.7 11.8
Garden 6.4 4.2 10.6
Other 0 2.6 2.6
Total 12.5 12.5 25
Agricultural manures and slurries account
for a further 90 million tonnes

Benefits:
Diversion from Reduction in N fertiliser use Carbon positive
landfill of ABP and Methane capture. Renewable energy
non ABP organic Cost savings to farmers. CHP biomass fuel (tbc)
waste
28. Digestate/compost management
Significant additional
environmental benefits if
successfully recycled to
land
Significant commercial
downside if mismanaged
