New, harmonized terminology is discussed and proposed in a paper published recently in the International Journal of Life-Cycle Assessment (LCA), entitled “Mineral resources in life cycle impact assessment—defining the path forward”. Co-authored by the ECI, this new paper, supports the LCA practitioners to build mutual understanding with the mineral industry, and recommends tools for use in life cycle sustainability assessment.
Condenser coils with round copper tubes and aluminium fins have been a winning combination for ACR coils for many years.
