Anaerobic Digestion A natural treatment method for organic waste Biological decomposition of organic matter in an environment without air supply Production of gas as recoverable energy (biogas) Used for organic waste with a high carbon content (soluble COD) Low volume sludge production Undigested matter can be dried and used as biomass fuel Residual organic matter used for composting and landspreading 5
Anaerobic Digestion and Waste Water Anaerobic Digestion and Waste Water Anaerobic digestion processes are used in the treatment of biomass from waste effluent, sludge, and organic matter produced by industry. The process is a very compact and efficient proven process can reduce loads of COD by 70-90% produces significantly less volumes of sludge than aerobic processes reduces the risk of odour can be applied to concentrated liquid or semi-solid organic wastes with high dissolved COD loads (4.5 to 100g/l) including: � Sludge from aerobic treatment of industrial effluent � Organic waste from industrial activity � Waste from catering service � Sludge from municipal wastewater � Municipal waste 6

Benefits go beyond treatment performance Benefits go beyond treatment performance Anaerobic Digestion Process gives following main benefits High efficiency Production of a sludge with high fertilizer value (PKN) Renewable energy production: biodegradable organic matter is converted into biogas 70 – 80% methane (CH4), a source of “green energy” Cogeneration to thermal or electrical energy (non fossil fuels) Greenhouse gas reduction. CH4 recovery provides carbon credits allocations if sites consumption > 20 MW/yr 8
Benefits of Anaerobic Digestion Benefits of Anaerobic Digestion Cost savings in line with increased energy prices Attracts Government Incentive Programmes (renewable energy) Carbon Credits Reduction of Industrial Environmental Impact Demonstrates Sustainable Development Policy A Solution to Local Limitations on Organic Waste Disposal Wastewater + Organic Waste � Non Fossil Energy Biogas offers a combination of the Veolia Group Environmental Services of Water + Energy + Waste. 9

Case Studies - Brewing and Distilling Brewing Company, UK Client’s needs The Client A solution was required to reduce the One of the world’s leading high cost of discharging untreated brewing groups with a strong wastewater to sewer and minimise the international market position. At impact to the local environment. It was this site, well known brands are the clients requirement to treat site brewed and packaged . wastewater and discharge to river to achieve both of these aims. Our solutions The results and benefits The turnkey project was Veolia proposed a turnkey solution commissioned in October based on high rate, small footprint 2007.Veolia will also operate anaerobic/aerobic processes, the WWTP on behalf of the including recovery of by-products brewery. The plant will such as methane. discharge to river. 11
