| Abstract:
RHP is currently developing a classification system that expresses the environmental quality of growing media. The system intends to offer producers and (professsional) users transparency about the environmental quality of a particular substrate. Depending on their environmental profile, growing media are awarded an A, B or C classification. This classification is based on clear and public criteria. The criteria applied are partly quantitative, partly qualitative. The quantitative criteria are based on LCA's (lifecycle analyses), which have been made for all major raw materials and additives. The qualitative criteria address aspects that are hard to quantify, but are nevertheless environmentally relevant, such as the level of environment management in the various stages in the production chain (including end-of-life). | |
