KillSpill delivers innovative (bio)technologies, which can be integrated to the real sequences of state-of-the-art actions used currently to cleanup oil spills. The catalogue of KillSpill products & technologies is based on a review of technology & knowledge gaps in approaches of oil spill disasters and brings appropriate tools for 1st response, follow-up, and longer-term actions, specifically tailored to the versatility of oil spills. KillSpill develops chemicals & biochemicals to be used for 1st response actions to disperse/emulsify oil and materials enabling the containment and sorption of oil, preparing the field for the follow-up actions. KillSpill develops (Bio)technologies aiming at intensified biodegradation processes by bioaugmentation/biostimulation as follow-up and longer term actions in aerobic/slight anoxic compartments. KillSpill develops (bio)technologies adapted for the remediation of anoxic/anaerobic fresh & chronically polluted sediments. KillSpill compiles knowledge on dispersion/sorption and biodegradation processes to produce multifunctional products, which are suited for follow-up and longer term actions. The multifunctional products address the necessity for integrated bioremediation (bioavailability, metabolic requirements, etc.) and are efficient along the whole redox gradient from surface water to sediments. The products/technologies are field-tested in open sea oil spills and large mesocosms to unravel the champions products & technologies. The (bio)tools are benchmarked with existing solutions using cutting-edge analytics, biosensors, and omics and checked for eco-efficiency to merit green label. KillSpill consortium is multidisciplinary and gathers 35 partners from 11 EU and EU-associated countries and USA; 20 research & academic institutions, 13 SMEs, 1 large company, and 1 association of oil spill companies work together with the support of a high level advisory board to cover the whole chain of oil spill (bio)remediation.
