UK Waste Production and Developments

 Estimates that 27.5 Mt of
residual waste arising from LA
MSW and C&I sources
2012/2013
 wider residual waste treatment
capacity either operating or
under construction approx 18.2
Mt, resulting in a 9.3 Mt
capacity gap
 It all facilities in the planning
stage are successfully
commissioned = overcapacity
of 12 Mt (if the waste remained

UK Waste Production and Developments
 The UK generated:
 518kg per person (2011)
 which was then treated with:
 landfilling (49%);
518kg
MSW waste produced per
person in 2011
 incineration (12%);
 recycling (25%);
 composting (14%) (Eurostat 2013)
• We send approximately 330 ktpa to Tyseley’s
incinerator
• Struggle to know what is in the ‘black bag!
UK & EU Policy
Non-waste
 2008 Waste Framework
Directive (2008/98/EC)
 Hierarchy of activities
Prevention
Preparing for re-use
Waste
 The largest component of MSW
Recycling
is organic matter
 Tick box exercise
Recovery
 Leaders such as germany:
Disposal
organic matter greater than 3%
is not allowed to be landfilled

Concluding remarks

UK has benefited from clear and enforced policy (sticks and carrots)

Indian waste composition is similar to that of the UK in the past

MRFs do not seem economically viable as a solution currently

GPC and Gate fees improve the economics of food waste AD under the
assumptions

Smaller systems (decentralised) require more support than larger
systems

Increasing electricity rates help support SWM technology viability

We would like to get your contribution for ways to improve the Indian
economic analysis
