• Zero Waste Plan & Waste (Scotland) Regulations
• Renewables policy in Scotland
• Handling by-products from food and drink sector & Resource
Efficient Scotland
• Feedstocks in, digestate out and PAS110 accreditation
• SEPA / Planning approval process
• Support for industrial AD in Scotland
• Innovation

3. Zero Waste Plan – key elements
• Issued – 9th June 2010
• Sets out key actions & targets to tackle the 20M t/y
waste produced by Scotland:
– 70% recycling by 2025
– Carbon metric
– Mandatory separate collections
– Landfill bans
– EFW input controls
– Managing Scotland’s resources for
Scotland’s economic &
environmental benefit

4. Zero Waste Plan – re-thinking
waste
• Resource efficiency underpins strategy:
– Reducing waste arisings
– Ensuring waste produced is recycled into quality
products
– Using recycled products to reduce the carbon-
impact of the supply chain e.g. using recycled
products (compost/digestate) to grow food
• Closing the loop….

5. Waste (Scotland) Regulations
Key points as follows:
• All businesses and organisations to present key recyclable
material for collection from 1 January 2014
• Food waste businesses producing over 50kg of food waste per
week to present it for separate collection from 1 January 2014
• Food waste businesses producing over 5kg of food waste per
week to present it for separate collection from 1 January 2016
• A ban on the use of macerators to discharge food waste into the
public sewer from 1 January 2016
• A ban on municipal biodegradable waste going to landfill by 1
January 2021

6. • Climate Change Act – emissions reductions target of 42%
by 2020 & decarbonisation of electricity supply by 2030, and
decarbonised heat by 2050
– 2020 Routemap for Renewable Energy in
Scotland
Renewables policy in Scotland

7. 2020 Routemap for Renewable Energy in
Scotland
• Updates the Renewables Action Plan 2009
• New, more challenging targets
• 100% of electricity demand from renewables
• 11% of heat demand from renewables
• 10% transport
• Alongside 12% energy reduction target

8. Handling by-products from food
and drink sector
• Food Waste materials
o Household - 566,000 tonnes
o Hospitality Sector - 67,728 tonnes
o Public Sector – 14,000 tonnes
o Industrial food Waste – 1,590,000 tonnes
• Currently 470,000 tonnes of the above is still sent to landfill
• Most is suitable for AD

9. Resource Efficient Scotland:
Food & Drink
“To support business, the public and third sector to
implement actions that reduce their material
consumption and waste production, and increases
energy and water efficiency to benefit their
economic performance”

10. Resource Efficient Scotland: Food &
Drink
• Food & Drink is a priority sector for Resource Efficient Scotland
• Food & Drink’s importance to the Scottish economy and the
resources it uses
• This includes:
- Agriculture
- Food & Drink Manufacturers/Processors
- Grocery Retailers
- Wholesalers
- Pubs & Clubs

11. Resource Efficient Scotland (RES):
Food & Drink
• Type of support:
- Focus on implementation (saving money and reducing energy, material
and/or water use)
- Advice & Support Service, potential for 1-1 support
- Case studies, tools and best practice guidance
- For innovative projects or tackling issues that affect an entire sub-
sector then bespoke projects can be developed
• Includes industry voluntary agreements such as Courtauld Commitment 3,
Hospitality and Food Service Voluntary Agreement or Federation House
Commitment.

12. Industrial AD Input materials
• Food Waste materials
o Industrial food Waste – 1,590,000 tonnes
• Most of this material will be suitable for AD including most food /
drink processing effluents
• Potentially reducing waste water / SEPA charges

13. Output - Digestate as a product
• Very liquid, typically only around 3 - 14% fibre content
• Valuable resource
• Cheaper than synthetic fertilisers
• Replacement or partial replacement for mineral fertilisers
• Contain useful quantities of P, K, Mg, S and trace elements.
• Liquor is an excellent source of readily available N
• Can offer carbon savings and long-term soil benefits when
compared with synthetic fertilisers
• What goes in comes out!
• Excellent opportunity to ‘close the loop’ with suppliers

14. Current markets
Markets are still in their infancy, but work is being carried out by
ZWS to help develop good, stable, long term markets for this
product, currently they are
• Agriculture – the biggest market and the most likely market
• Landscape and regeneration
• Horticulture
It is most likely that markets will require / demand PAS110 quality
digestate

15. • Source-segregated biodegradable inputs
• De-packaging allowed
• HACCP, Quality Management System
• Pasteurisation / sanitization steps
• End product testing
• Product quality driven by inputs
• Must comply with SEPA requirements
• Guaranteed market
• No additional processing needed
The product route: PAS110

16. The waste route
• No need for PAS110
• Not a product so classed as a ‘waste’
• Exemption needed from SEPA
• Unlikely to be allowed under farm certification schemes
• Land for waste disposal needs to be secured

17. SEPA
• PPC licence for AD plants >100 tonnes per day
• WML for AD plants <100 tonnes/day
• WML + exemption for AD plants taking distillery wastes, agricultural
wastes or a mix of both <100 tonnes/day
• PPC for any AD plant with >10 tonnes/day of animal waste (likely to
include catering wastes, not manures and slurries)
• All on site AD plants or ‘Hub’ plants

18. Planning
• Most sites – ‘general industrial use’
 Planning shouldn’t be a problem
• ‘Hub’ sites may be different

19. Support for Industrial AD in Scotland
 Up to £10,000 for feasibility study into industrial on site AD
(must be match funded and not exceeding 50%).
To be eligible to apply for funding your applicant must:
• be a food and / or drinks producer / hospital based in Scotland;
• the site must be located in Scotland;
• have the feasibility study completed by 31st March 2015;
• demonstrate that on-site AD would improve resource efficiency
e.g. through reducing waste disposal and costs, providing on
site renewable energy;
• provide information (non-commercially sensitive) on the
development and performance of the project for potential use
in case studies.

20. Innovation
• Driving Innovation in AD
• ZWS Innovation funds
• Keen to develop Scottish inter industry & Academic
collaboration for the development & benefit of AD
