Land, and particularly the soil, and its use is the focus of all our work. We have in depth knowledge of agricultural soils and how the addition of Controlled Wastes may affect it, and farming and wider environmental outcomes. While we have spent over 30 years being deeply involved in recycling urban wastes to land, in recent years we have been increasingly involved with developing front line, probably second to none, experience in recycling the arisings of cuttings and spent fluids from HDD (Horizontal Directional Drilling) and tunnelling.
