Important results from the project
** Denna text är maskinöversatt ** The purpose of the preliminary study is to identify the opportunities that the use of circular salt can give to reduce the negative impact of road maintenance on the environment and climate. Another aim of the feasibility study is to identify the conditions required for switching to the use of circular salts in aim to achieve sustainable road maintenance and emission-free maintenance contracts. The goal is to create a knowledge base to achieve sustainable road maintenance through the use of circular road salts.
Expected long term effects
** Denna text är maskinöversatt ** Circular salt is an important product in road maintenance to achieve our environmental goals. Sodium chloride will in the foreseeable future not be produced in Sweden to an extent so that we become self-sufficient, on the other hand, it can provide important funding for the salt supply in critical situations to increase our civil preparedness. However, circular salt has good conditions to provide important funding in reducing the CO2 footprint as the difference is very large compared to the conventional alternatives.
Approach and implementation
** Denna text är maskinöversatt ** The project began with literature studies to gather and update knowledge about circular salts. Through interviews with actors within the value chain (e.g. road managers, contractors, salt producers, etc.) we build knowledge about understanding their expectations and objective. Two workshops have been held with contractors, road maintainers, machine manufacturers and salt producers. Three study visits have been made to salt manufacturers, road maintainers and machine manufacturers.
