  7. METHODOLOGY /WORK DESCRIPTION7 TASKS

  8. Task 1 (month 1 – 24)Inventory of legislation on biological treatment operations and compost and digestate use in each participating country

  9. TASK 1 (1/3) 1. Standards on compost and digestate use on agriculture and other activities IMPOSITION OF CONSTRAINTS ON: Inorganic and organic contaminants: heavy metals, PCBs, PAHs, dioxins, man made inert materials Sanitization: pathogenic microorganisms, germinating weed seeds, process control Maturation degree (degree of Rotting) Application rates: amounts, periodicity, restrictions for application Others: minimum organic matter content, maximum water content, etc

  10. TASK 1 (2/3) 2. Standards on biological treatment operations Concrete restrictions, e.g.:  Reduction in odour of exhaust air to less than 300 OU/m3

  11. TASK 1 (3/3) Compost Directive Proposal

  12. Task 2 (month 1 – 24)Inventory on existing methods of characterisation for evaluating process efficiency and compost quality in each participating country

  14. TASK 2 (2/3) 2. Methods of characterisation for evaluating compost quality Standards with the imposition of constraints on compost quality normally refer to standard methods of analysis for evaluating that quality, e.g.: - sampling - heavy metals - pathogenic microorganisms - maturation degree etc.
