UK policy for supporting the development of solid waste management infrastructure and its application to India Dr Daniel Wright Dr Jim Scott Prof. Prasanta Dey Aston Business School
Presentation Agenda • UK waste production and developments • Enablers to the UK and EU SWM policy • Waste Framework Directive • Landfill Directive • Landfill tax & effects • Energy Production incentives • MSW composition trends • SWM infrastructure case to India
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 approx18.2 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 static) Figure 1: Total UK waste generation by sector, 2004 to 2010 (DEFRA 2013) * Other includes healthcare wastes, batteries & accumulators, and wastes containing PCB
UK Waste Production and Developments • The UK generated: • 518kg per person (2011) • which was then treated with: • landfilling (49%); • 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! 518kg MSW waste produced per person in 2011
UK & EU Policy • 2008 Waste Framework Directive (2008/98/EC) • Hierarchy of activities • The largest component of MSW is organic matter • Tick box exercise • Leaders such as germany: organic matter greater than 3% is not allowed to be landfilled Figure 2: Waste hierarchy
UK & EU Policy • approximately doubled from 2004 to 2013 Figure 3: Quarterly non-domestic electricity price trends (DECC 2013)

MSW Composition – Comparative Assessment Drives the MRF economics
MSW Composition – Comparative Assessment • Previous MSW composition similar to that currently in India – Future systems • MRF not currently viable in India Figure 6: Trends in household-collected waste composition 1935–1980 (percentage by weight) (Bridgwater, 1986)
SWM Technology Support – AD case study • 3 scenarios for the capital and operating costs (100%, 90%, 80%) • System efficiency 36.5%, 84% annual load availability, • wholesale rate estimated at 4Rs/kWhel (MNRE 2013) • The investment term has been set at 10 years @ 15% Figure 7: Published AD facility costs The exchange rate of 101.45:1 INR to GBP is maintained throughout the model.
SWM Technology Support – AD case study • Example: • 68 ktpa food waste • Feedstock cost = 0Rs • 4Rs Power (kWhel) + 10Rs GPC • Missing costs & cost of finance • SPB 5 years • Meets the financial target ‘hurdle rate’ Table 4: Example techno-economic case
At 100% cost Viable AD scale (ktpa) SWM Technology Support – AD case study • What is the minimum size of food waste AD plant to meet this target? • Low to no gate fee + low to no GPC = very large systems • Higher rates = smaller systems At 80% cost Green production cert. (INR/kWhel) Feedstock price (INR/t) • * the surface shown displays the minimum size the AD scheme can be to meet the required threshold return over the investment term Figure 9: Viable AD sizes under different feedstock and green certificate rates
SWM Technology Support – AD case study • Lets assume a going rate of -£1500 Rs/t • Low to no reliance on a Government run GPC system to meet the investment target Table 5: Green production certificate rates
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
