3 Objectives Main objective is to promote biogas production and use as traffic fuel Aims in the four Finnish and two Estonian case areas are: To reduce the amount and improve the sustainable use of waste and sludge To promote biogas production To start biogas use as traffic fuel To provide tools for implementing aims To increase networking of municipalities, companies, associations and research organisations To raise awareness of the environmental, economical and regional effects of biogas traffic fuel use

4 Target areas

5 Methods Collecting information on regional waste, sludge, manure and energy crop streams, field areas, vehicles, traffic etc. Producing viable plans for six case areas on study areas METHANE CASE FOR YEAR 2020 Biowaste and sludge prevention Biogas production Biogas use as traffic fuel Comparing produced plans to BASE CASE 2020 Comparing environmental, economical and regional effects of methane and base case

6 BIOWASTE SLUDGES MANURE ENERGY CROPS BY- PRODUCTS BASE CASE 2020 METHANE CASE 2020 Collection of biowaste and treatment as now or as planned in region Municipal sludges: AD + CHP Industrial sludges: Incineration Treated in traditional way and used in fields Waste prevention target -30%, more effective separate collection of biowaste. Biowaste is treated in AD and produced biogas used as vehicle fuel. Treated in AD + Vehicle fuel Treated in AD, digestate is used in fields and produced gas for vehicle fuel No cultivation of energy crops Energy crops cultivation on available land, treated in AD + vehicle fuel Treated in traditional way Treated in AD + vehicle fuel Environmental and economic impact assessment of both cases

7 Main results in Finnish case areas 30 % food waste prevention about t CO 2 eq emission reduction is achieved in TWh energy could be produced from available biomass with biogas technology in studied areas According to available biomass about 50 large scale biogas plant could be build Total energy production of 2.2 TWh energy From 5 to 40 % of areas vehicles could use biomethane as fuel Using all produced biogas as vehicle fuel would bring as much environmental benefits as removing over passenger cars from traffic With 30 % food waste prevention additional passenger cars Biomethane production from waste materials is profitable Biomethane production from agricultural materials is profitable after demand has become established
