WP 6 – BIODEGRADABILITY Stakeholders Workshop – Brussels, Jan-16-2013 Bruno DE WILDE – Nike MORTIER WP 6 – BIODEGRADABILITY OBJECTIVES – SCOPE * TEST METHODS and SCHEME for DIFFERENT ENVIRONMENTS BIODEGRADABILITY + ENVIRONMENTAL SAFETY BIOLUBRICANTS + BIOSOLVENTS (+ BIO-OTHERS) * ACCEPTANCE CRITERIA (= SPECIFICATIONS) * VALIDATION 1
WP 6 – BIODEGRADABILITY - OBJECTIVES – SCOPE PRODUCT USE/DISPOSAL UNCONTROLLED CONTROLLED (LITTER) WASTEWATER SOLID WASTE OPEN WATER SOIL MARINE AEROBIC ANAEROBIC TREATMENT TREATMENT ANAEROBIC COMPOSTING BIOGASIFICATION LANDFILL STABILISATION CENTRAL HOME USE OF COMPOST I N SOIL WP 6 – BIODEGRADABILITY : WHY ? * OECD GUIDELINES FOR TESTING OF CHEMICALS : SIMPLE, UNIFORM MOLECULAR STRUCTURES (detergents) NOW : COMPLEX, HETEROPOLYMER STRUCTURES * REPRODUCABILITY (intra, inter, but also GEOGRAPHICALLY) * CREDABILITY (many false claims, much miscommunication) * DISTINCTION TEST METHODS vs ACCEPTANCE CRITERIA * STANDARDISATION (CEN – ISO) 2
WP 6 – BIODEGRADABILITY : WHY ? * AQUATIC : - nitrification - long-term tests - standard inoculum - microbial diversity - suitable reference * SOIL : - nature (granulometry) + geography of soil - standard inoculum - microbial diversity - nutrients - suitable reference - weathering - aeration - effect of T WP 6 – BIODEGRADABILITY PROJECT DESCRIPTION * Task 6.1. LISTING AND CRITICAL REVIEW OF CURRENT STANDARDS (worldwide, biodegradation + environmental safety, weathering) * Task 6.2. DEVELOPMENT BIODEGRADATION TESTS AND SCHEME for LUBRICANTS and SOLVENTS (different types of soil and water, also anaerobic + marine; optimisation, specifications) * Task 6.3. ENVIRONMENTAL SAFETY : TESTS + SPECS * Task 6.4. VALIDATION (correlation with real-life, reproducibility, round-robin tests) 3
WP 6 – BIODEGRADABILITY : DELIVERABLES * 88 mm - M1 till M36 * D.6.1. Report on current biodegradation and ecotox standards (M6) * D.6.2. Draft standard(s) on biodegradability and environmental safety (M.24) – Report to CEN * D.6.3. Evaluation study on eco-toxicological impact and labelling possibilities (M.18) – Report to CEN * D.6.4. Validation report on standard(s) including advice on acceptance criteria (M. 36) * D.6.5. Biodegradability standards assessment (M.36) WP 6 – BIODEGRADABILITY : PARTNERS * LEADER = OWS, Nike Mortier, Bruno De Wilde, Steven Verstichel * ACTIVE PARTNER = AUA, Prof. Briassoulis, Dr. Mistriotis, Dr. Hiskakis * EVALUATION PARTNERS = DLO-FBR, Dr. van der Zee (and UoY) * EXTERNAL CONTACTS = Scion, ASTM, EuropaBio, EuBP, ACV 4
WP 6 – BIODEGRADABILITY : MANAGEMENT * MILESTONES M1 – m6 – Report on review – Final definition of needs M2 – m24 Proposal for standards : methods, scheme, specs – Planning for validation M3 – m36 Draft standards available WP 6 – BIODEGRADABILITY : OPEN QUESTIONS - VARIOUS * Additional issues * Questions * Things not yet addressed 5
