According to guidebook 'Excavated soil and land-clearing debris do not contribute to this credut', does it mean soil is not counted as construction waste, or non-recyclable waste (but still counted in the denominator as total quantity of waste)? If the waste generated in the foundation stage is mainly rock and soil, and the description in the receipt issued by public fill is "mixed rock and soil", shall we count this quantity as recyclyed waste as a whole, or give a proportion, say 50% rock 50% soil, then count 50% of that quantity as recycled waste? Thanks
