How to Easily Depolymerize Polyurethane Foam Wastes by Superbase Catalysts in Ionic Liquids Below 100 °C.

This study introduces a novel and sustainable approach using Ionic Liquids (ILs) as a non-innocent solvent that enhances the performance of the basic catalysts to depolymerize polyurethane foam wastes (PUFWs) through hydrolysis, alcoholysis or aminolysis under mild conditions. The system is stable, fully recoverable, and reusable. Hydrolysis of PUFWs can occur in just 2 minutes at 95-98 °C, producing a white polyol that is easily separated and reused in new polyurethane synthesis.

Safety and efficacy of a feed additive consisting of NCIMB 41028 for all animal species (Genus Breeding Ltd.).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of NCIMB 41028 as a technological additive to improve ensiling of fresh plant material. The additive is intended for use in all fresh material for all animal species at a proposed minimum concentration of 1 × 10 colony forming units (CFU)/kg fresh plant material. The bacterial species is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment.

Safety and efficacy of a feed additive consisting of an essential oil derived from the leaves of L. (sage oil) for use in all animal species (FEFANA asbl).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from the leaves of L. (sage oil) when used as a sensory additive in feed and in water for drinking for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that sage oil is considered safe up to the maximum proposed use levels in complete feed of 20 mg/kg for ornamental fish.

Assessment of the feed additive consisting of NCIMB 40027 for all animal species for the renewal of its authorisation (Volac International ltd).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of the authorisation of NCIMB 40027 as a technological additive (functional group: silage additives) for use in fresh material for all animal species. The applicant has provided evidence that the additive currently on the market complies with the existing terms of the authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive remains safe for all animal species, consumers, and the environment.
