en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv
Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap …
