HS2 has introduced a new approach to tackling Invasive Non-Native Species (INNS), saving time, money and carbon output by minimising soil excavation and heavily reducing waste to landfill. HS2’s contractor Fusion JV worked with specialists in AECOM to manage a range of INNS, including the removal of significant areas of Japanese knotweed in the Colne Valley area. Minimising excavation saves substantial time, cost and carbon footprint by heavily reducing waste to landfill, resulting in cost savings estimated at £1.8m.
