Ecotoxicity of Nanomaterials Used for Remediation [PDF]

, 2020
Remediation using nanoparticles depends on proper documentation of safety aspects, one of which is their ecotoxicology. Ecotoxicology of nanoparticles has some special features: while traditional ecotoxicology aims at measuring possible negative effects of more or less soluble chemicals or dissolved elements, nanoecotoxicology aims at measuring the ...

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability. Existing Safe‐and‐Sustainable‐by‐Design

Circular economy assessment of biomethane value chain in Brazil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract From the numerous opportunities to add value to biomass in Brazil, biomethane production in sugarcane mills presents significant potential. This study introduces a diagnostic framework grounded in circular economy (CE) principles to assess new biomethane projects, aligning with the strategic objectives of product diversification, full biomass ...

Ecotoxicity

, 2015
Ecotoxicity impact assessment of chemicals in life cycle assessment (LCA) adheres to a number of underlying principles and boundary conditions: 1) a large number of emitted substances to cover (at least 100,000 potentially relevant elementary flows with current models covering around 2500), 2) linearity of characterisation models, 3) conservation of ...

Towards appropriate guidance for the ethical challenges of environmentally sustainable prescribing

British Journal of Clinical Pharmacology, EarlyView.
The environmental impact of medicines poses a significant threat to planetary and public health, making it essential to integrate environmental sustainability into prescribing practices. While the most effective measures to reduce environmental impact, such as reducing unnecessary prescriptions and medication waste, are consistent with appropriate ...

Ecotoxicity of artificial sweeteners and stevioside

Environment International, 2013
Produced, consumed and globally released into the environment in considerable quantities, artificial sweeteners have been identified as emerging pollutants. Studies of environmental concentrations have confirmed the widespread distribution of acesulfame (ACE), cyclamate (CYC), saccharin (SAC) and sucralose (SUC) in the water cycle at levels that are ...
