Company overviewCompany overview
o Founded in 2002, Gasrec has assembled a portfolio of exclusive technologies to
o Produce biogas from landfill and other waste streams
o Use the biogas as cost effective, carbon negative vehicle fuel or for renewable power generation
o market to customers who require cost effective energy solutions and want to enhance environmental credentials
o Exploit current legislative drivers and public opinion
o These technologies are patented, proven and commercial and are applicable to a global problem
o Mission statement
“To produce a carbon neutral fuel from society’s waste to power those vehicles and services essential to society”
3
OpportunityOpportunity
o Landfill
o 300 UK landfill sites generating 1,700 MW/h of renewable power
o Further c40 sites producing gas which cannot be exploited to produce renewable electricity
o renewable value of the gas is insufficient – NFFO contract;
o local grid connection cannot accept the load -‘wires full’; or
o gas is contaminated and causes damage to plant and equipment
o Approximately 75m tonnes of waste is sent to landfill each year in the UK alone
o 1 tonne of organic waste in a landfill produces 70m3 of methane over time
o Other waste
o Food retailers produce in excess of 1m tonnes of putrescible food waste each year
o At a conservative estimate, UK distilleries and breweries produce c3x that amount
o Water and sewage companies produce substantial volumes of biogas as a process byproduct
o 1 tonne of typical feedstock can produce 40m3 of methane depending on residence time
4
Strategic rationaleStrategic rationale
o All organic waste produces methane on decomposition
o waste disposal viewed as a cost
o waste is a resource that can be exploited
o Provide benefit to society from its waste
o Society produces large amounts of food waste
o Food transported predominantly by road
o 25% of all road miles are food miles
o link waste production to fuel consumption - virtuous circle
o Focus on niche market
o urban environment
o “back to base” fleet operations
o municipal vehicles (buses, RCVs)
o delivery vehicles (HGVs)
o Decentralised CHP

ProductProduct
o Liquid Bio Methane – “LBM”
o LBM is a readily transported fuel with the following characteristics
o direct substitute for either LNG or CNG
o storable and transportable
o Lowest carbon intensity of any readily available fuel
o Vehicle fuel
o cheaper and cleaner than diesel, CNG or LNG
o very dry compared to CNG
o 1Kg of LBM provides the same energy as 1.2 litres of diesel
o Renewable power generation
o 1 tonne of LBM produces 5MW/h of electricity or c10MW/h of CHP
o retains renewable status and qualifies for ROC credits
o Lack of contaminants benefits both the environment and engine durability

Albury Landfill ProjectAlbury Landfill Project
o Albury Landfill near Guildford
o Landfill site owned and operated by SITA UK
o Project life 15 years
o Site processes 4 million tonnes of Surrey’s domestic waste
o Organic degradation will produce min 2,250 m3/hour @50% CH4
o When processed gas will produce c5,000 tonnes of LBM per annum
o Sufficient energy to
o propel 100 HGVs or 400 LGVs per annum
o Provide 28,000 MW/h of offsite electrical power per annum; or
o Provide 60,000 MW/h of offsite CHP per annum

Benefits as a vehicle fuelBenefits as a vehicle fuel
o Carbon offset
o When used as vehicle fuel provides a 70% reduction in CO2 emissions v fossil diesel or petrol
o Has the lowest carbon intensity of currently available biofuels
o Application for methodology approval under CDM/JI through SCC
o Air Quality
o 90% reduction in particulate matter production
o 60% reduction in Nitrous Oxide
o 50% reduction in Sulphur Dioxide
o 30% reduction in engine noise
