[:es](Environmental Regulations: Impacts and Mitigation Strategies)Materials and processes historically used by the aerospace industry are continually impacted by environmental legislation. Domestic regulations and international agreements have banned or heavily restricted certain materials from future use or production, making it necessary to find replacements that comply with environmental regulations and provide equivalent performance.Replacing materials and processes with environmentally-friendly substitutes also moves the space sector toward an explicit consideration of sustainability in the development of new technologies.Topics will include the Registration, Evaluation, Authorisation and Restriction of Chemical (REACH) Regulation, Other environmental regulations with the potential to impact the space sector, evaluation of environmental impacts of propellants (i.e. liquid vs solid propulsion), effolrts to protect assets from corrosion, solvent replacement efforts, specific materials and technologies and fundamental research in materials science that can support a more sustainable space sector.[:]
