4 Scale of AD industry in UK 104 plants in UK (plus 146 plants in water industry) Wide range of capacities Electric production capacity of 88MW Plants are community (waste fed), agricultural or industrial 4

8 Why AD? Waste (Scotland) Regulations > Requirement for separate food waste collections > Ban on macerators > Landfill ban for biodegradable waste Incentives Benefits of Digestate 8

9 Incentives Feed-in Tariffs (FiTs) > Facilities with less than 5MW capacity > 3 bands - tarriff dependent on size > Degression from 2014, issue for plants <500 kwe Renewables Obligation Scotland > All scales of plants > Currently 2 ROCs/MWh > From 2017, closed to new generators 9

10 Incentives Renewable Heat Incentive > Biogas combustion up to 200kW scale receives 7.3p/kWh > Larger scale (phase 2) announced summer 2013 > Biomethane injection to grid receives 7.3p/kWh Levy Exemption Certificates Renewable Transport Fuel Obligation 10

11 Biofertiliser Certification Scheme Provides assurance to consumers, farmers, food producers and retailers that biofertiliser is safe and of good quality. The BCS uses the PAS110 and additional scheme rules as instruments recognised by SEPA as end of waste criteria where the material becomes a product. Material can be used in markets specified where waste regulations do not apply. 11

12 PAS110: 2010 Specification for digestate including: > the requirements for a QMS and HACCP > control of input materials > Process management and monitoring > Pasteurisation > Testing parameters and upper limits > Actions in the event of a test failure 12

13 Consultancy Support WRAP funded consultancy support to assist plant operators become certified Maximum of 3 days support available for 10 plants up to end March 2014 Assist with QMS, HACCP and identify any other compliance issues Consultant allocation administered by BCS - contact us to request an application form 13

14 Benefits of Digestate Excellent alternative to bagged fertiliser > Readily available nitrogen > Useful amounts of phosphate and potash Financial value of nutrients in digestate 6.55 per tonne Lots of WRAP trials demonstrating benefits 14

15 Challenges Funding Uncertainty of tarriffs and incentives long term Difficult for small scale plants Planning community engagement very important Quality Assurance Schemes acceptance of digestate 15
