Clean soil is soil from areas that have not been mapped, classified or suspected of being contaminated. All urban soil is generally classified as slightly contaminated, but can change classification after sampling, according to the Land Relocation Order, if the soil meets the classification requirements for clean soil. Clean soil is classified as class 0/1 soil or category 1 soil, according to the Land Relocation Order and the Zealand Guide. At Blue Phoenix, we take samples of surplus soil per 30 tons, which documents that the soil can be classified and thus sold as clean. There is a minimum of 50 cm of soil in the upper layer.

All soil is a composition of silt, rock, gravel and sand. The geotechnical composition thus determines what the clean soil can subsequently be used for. Clayey soil can be lime stabilised, loamy soil can be included in new loam products and soil with many stones and sand can be washed and turned into recycled materials. In other words, clean land is an important resource.
