Project Outline

Suffolk EfW Facility Project Financing, Construction and Operation of a 269,000 tpa EfW Facility Treatment of the Residual Waste collected by Suffolk’s Councils 25 year PFI Contract with Suffolk County Council Partnership between Suffolk County Council and SUEZ Four phases: Procurement: Autumn 2008 – 5th October 2010 (Financial Close PFI) Planning: Spring 2010 – 8th August 2011 (Planning permission) Construction: 25th November 2011 – 1st December 2014 Operation: until 30th November 2039 (25 years) Potential extension up to 5 years

The benefits EfW provides a cheaper, greener solution to disposing of household and some business waste It puts the waste to good use as a fuel to generate enough electricity for 30,000 homes + potentially some heat Economic benefits – 45 permanent jobs plus around £1million spent in the local economy per annum Cost benefits: at least £350 million cheaper than continuing to landfill. Reduction in greenhouse gases – 75,000 tonnes a year

EfW in context: What is the cost of dealing with non-recyclable waste v’s recyclable waste For councils in Suffolk, waste management costs are made of 2 elements. Collection costs Treatment costs Indicative costs based on last full year of data available 2014/15. Shown as approximate estimates to the councils in Suffolk. Direct collection and treatment costs only, excludes other associated costs such as admin, support staff and premises. Costs are shown per household per year. 20/09/2018 Page 6

Waste specification Suffolk energy-from-waste facility can only accept non-recyclable waste The waste has to have a certain calorific value - between 8910 kj/kg and 9800 kj/kg Electricals items are a serious problem as they can causes spikes in our emissions, which we can control but would rather not have in the first place 20/09/2018 Page 7

The Build - EPC Contractor: CNIM-Lagan CNIM provided the Process Equipment Lagan provided the Civil Works CNIM is the leading manufacturer of EfW plants: - 250 incineration lines - 9 new plants being built in the UK currently

Main Project Features Site: Council’s former highways depot site in Great Blakenham The facility has 2 lines designed to process 15 tonnes per hour per line Landscaped wildlife area A visitor centre for community use An onsite ash processing facility

The site

Suffolk’s Energy-from-Waste visitor centre 2 rooms aimed at providing an overarching view of: Waste management Energy production and consumption Environment Energy from Waste process There has been a huge demand for visits - in 2015 we had 2,698 visitors.

The architecture Designed by Grimshaw architects Achieved BREEAM Outstanding rated building, making it one of the greenest buildings in the country.
