1 The Financial Argument For Improved Handling Of Energy From Waste

2 Waste to Energy Technology Is Ready for Solid Investment in the UK? The ever increasing debate around waste to energy vs historical landfill has been with us for several years. Governments around the world are focused on reducing the environmental impact that increased energy consumption creates. The Department for Environment, food & rural affairs (Defra) quoted in their energy from waste guide in 2014 waste to energy has a poor historical image in the UK. Northern Europe is clearly ahead of the UK, but with the right technology, planning and people, we have all the opportunities to create a world class solution. Saxlund Technology helps divert up to 80,000 tonnes of bulk solid waste from landfill at Hope Cement

3 Risk vs Investment The four crucial factors governing success for Energy from Waste (EFW) projects continue to revolve around: location technology fuel supply investment While significant project attention is focused on the technicalities of the selected thermal process and the energy conversion technology to which it is linked, there is a real danger if front end systems for fuel handling aren t as robust as the end point technology. If the design process fails to identify material handling efficiency it will have a direct bearing on whether the plant reaches its full potential.

4 Design That Ensures Consistent Delivery Push floor or sliding frame technology, continuously developed by Saxlund since the 1960s, is designed to break up the material, preventing any build up or bridging, to ensure a consistent, homogenous delivery to the discharge point. TubeFeeder technology provides an alternative option for the continuous reclaim of bulk materials from both circular and rectangular bunkers and large-diameter silos. Designed to handle large volumes of biomass, the TubeFeeders at RWE s Markinch site consume 25% less electricity than other systems. End to end the length of the Push Floor Ladders we re in contract for stretches over 1.5km

5 Saving Waste From Landfill In The UK In the UK, the construction of an innovative new Eco Park, being developed by SUEZ Recycling and Recovery as part of its 25 year PFI contract with Surrey County Council, will take general waste collected from homes in northern Surrey and also some from local businesses. It will incorporates the latest fluidised bed gasification technology producing syngas from waste to provide 3.5MWe energy to the national grid, enough to power up to 8,000 homes. Under the contract Saxlund International is responsible for the design, supply and commissioning of a fully automated fuel handling solution which will provide a fuel storage bunker for 2300 m3 of processed and screened waste fuel produced at the Eco Park.

6 Case Study: Anglian Water Anglian Water supplies water and water recycling services to over 6m domestic and business customers across a 27,500 km2 area. Providing almost 1.2 billion litres of water per day, making it the largest water and water recycling company in England and Wales. Anglian Water needed to meet Ofwat s obligation for it to provide enhanced digestion for 80% of its raw sludge production and to increase total renewable electricity output from biogas to 86.8GWh/year by Saxlund completed a series of projects for Anglian Water in Including the construction of raised storage silos, specially designed to allow de-watered sludge to be directly loaded into trucks below for transportation off site. With a much faster reception, less odour and less risk of contamination by foreign objects which could cause damage to plant and equipment or blockages downstream. DID YOU KNOW: 22% of the energy used by Anglian Water comes from renewable sources.

7 Silos designed for efficient reception and delivery Truck-loading silos using the latest sliding frame technology and screw conveyors enable greater volumes of sludge to be handled in a shorter space of time than traditional hook lift container storage systems. Whilst some storage silos may be cheaper, they may be of an inferior design and quality, and this can result in problems with bridging and discharging.

8 Case Study: RWE s Markinch Biomass Power Station Currently the largest dedicated biomass power station in the UK, the Markinch facility burns biomass fuel in a high-efficiency boiler, producing steam which is passed to a steam turbine to generate electricity. Saxlund was involved right from the earliest stage of this multi-million pound project in the design and development of the robust materials handling system, including full installation, project management and commissioning. Saxlund s solution is designed to minimise dust emissions, prevent material building up in silos or clogging conveyors.

9 Contact Saxlund International Saxlund International has the technology and infrastructure in place with a proven track record of sustainable growth in energy produced through waste to energy technology. Creating a reduced cost environment through combined solutions that gives investors the confidence to finance the projects. The company's practical experience in handling major projects stems from the fact that to date it has constructed more than 3500 plants worldwide. T: +44(0) E: info@saxlund.co.uk W:
