1 Converting Waste into Electricity as a Sustainable Source of Energy Water and Energy Sustainable Innovation and Industry (WESII) Conference & Exhibition 23 rd April 2018 Presented by; Mr. Gareth R Brown CEO, OAK Group Holdings

2 Regional Waste Generation Statistics & Demographics GCC Population Growth Rate (est. 2.7%) is Clearly Accelerating the Proportionate Rate of Waste Generation. GCC States are Ranked amongst the Highest Generators of Solid Waste per Capita. The World s Dependence on Middle East Energy Resources has caused the Region to have some of the Largest Carbon Footprints per Capita Worldwide. The Volume of Gross Urban Waste Generation from Middle East Countries has Reached 150 Million Tons Per Annum. The Kingdom of Bahrain alone Produces more than 1.5 million tons of recorded Landfilled Waste every Year (which is approximately 2.3 kilograms of Waste Per Person Per Day). Sources 2

3 Waste Generation (GCC) Statistics & Demographics Majority of Bahrain s Municipal Solid Waste (MSW) is Disposed of in Landfill. Landfills (as we know) come with Significant Environmental Risks including Greenhouse Gas Emissions (bio-degradation) and Ground Water Pollution as well as Occupying Precious Land. Country Recorded Generation (million tons per annum) Population (updated April 2018) Waste Per Capita/day (kg) Bahrain 1.5 1,781, Kuwait 2 4,161, Oman 2.3 4,181, Qatar 2.5 2,113, Saudi Arabia 13 31,521, UAE 5 9,154, Sources 3

4 Waste-To-Energy (WTE) What is WTE? Waste-to-Energy (WTE) or Energy-from-Waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste. WTE is a form of Energy Recovery. Most WTE processes produce electricity and/or heat directly through Combustion or produce a Combustible Fuel Commodity, such as Methane, Methanol, Ethanol or other Synthetic Fuels. Sources of Waste Feedstock Include; Bio-Sludge, Industrial Waste, MSW, Construction Waste, Medical Waste, Agricultural Waste and even Tyres, basically anything other than Glass or Metal can be Converted in to some form of an Energy Commodity! WTE offers us a Sustainable Source of Renewable Energy with Significant Positive Environmental Impacts, including the Elimination of Landfilling and the Reduction of Green House Gas (GHG) Emissions. 4

5 Waste Processing Technologies Some Examples of Existing Processes Used in Waste Management High Temp Pyrolysis Pyrolysis Gasification Plasma Arc Waste to Energy Incineration Landfill Methane Anaerobic Digestion What Exactly is High Temperature Pyrolysis? The thermal decomposition of Organic & Inorganic materials at elevated temperatures in an inert atmosphere (without Oxygen), producing Synthetic Gas and Biochar. 5

6 High Temperature Pyrolysis (HTP) With many plants operating globally, what is HTP? HTP is the Thermochemical Decomposition of Organic & Inorganic Materials that Effectively Transforms Solids into Gas. In General Terms, Processing Approximately 1 Ton Per Hour of Treated MSW (as RDF) could produce 1MWh which could Provide enough Grid Power to Support around 400 Households. HTP is a Closed Loop Process which Involves a Rotary Kiln that Operates at Elevated Temperatures (>700 C) and Accepts Waste without the Presence of Oxygen. Processing Waste at Higher Temperatures allows a more thorough Chemical Breakdown of the Waste hence Improving Production Yield and Minimising Emissions. HTP Produces a High Calorific Value Gas (similar to Natural Gas) which can be used to Power Gas Generators and/or Steam Turbines for Sustainable Generation. Gas Clean-up processing IP (SATCO) including Patents pending, operating on multiple sites worldwide. HTP Produces a Consistent Profile of Biochar (around 1% by-product) which also represents a Marketable Commodity in its own right (e.g. Fertilizers, Construction Material such as Asphalt etc).

7 Waste-To-Energy (WTE) WTE Benefits Utilising HTP Significant Reduction in Greenhouse Gas Emissions as well as the Elimination of Harmful Landfilling Underpins HTP as Environmentally Friendly. Cost-effective Energy Generation which is Considered Bankable and Financeable within the Correct Project Finance Commercial Framework. Rising Production of untreated Waste Types Represent an Endless Supply of Valuable (treated) Refuse Derived Fuel (RDF) Feedstock which can be Converted in to Energy on a Constant Basis. Compared to other thermal processing technologies, HTP is a Proven Process that is Operationally Efficient and Reliable with Low Parasitic Load. 7

8 WTE Plant in Bahrain Bahrain s First Waste-To-Energy Solution Converting Mainly Bio-Sludge Waste Derived from an Existing Waste-Water-Treatment-Plant using High Temperature Pyrolysis (HTP) and upstream dewatering, which will Produce Approximately 10MWh. Sustainable and Environmentally Friendly Solution which will Prevent Further Pollution and Destruction of our Precious Wetlands and Mangroves. The Plant is to be Constructed on 4,000m² of Land, an Area Smaller than a Football Pitch! The Plant will Convert Mainly Treated Sewage Sludge (TSS) into Base-Load Power for the Existing Waste-Water-Treatment-Plant. At Full Capacity the Plant will Convert Upto120tpd of Sludge and other Sourced Solid Waste. Construction is Due to Start in Q and the 1 st Phase will Provide >5MWh from the Processing of Approximately 70tpd of Refuse Derived Fuel (RDF). The Plant will Eliminate the need for Landfilling of Sludge, and Represents Significant Capital Investment Raised via Private Equity Placements and other Leveraged Instruments. 8
