Carbon Footprint Implications of the Erosion Control Response

Many geosynthetic erosion control technologies are complete only with a strong connection to vegetation establishment. Nature’s in-place and well-established success in stabilizing surface soils is the cornerstone in almost every erosion control application. The geosynthetic response is one of augmentation, stabilization, and water management because they encourage, strengthen, and reinforce the soil/vegetation matrix and direct flows to desired managed systems. In addition, the partnership of natural materials to geo“synthetic” reinforcement in erosion control materials serves to enhance and extend the functionality of the engineered product. The evaluation of the carbon footprint of these materials begins with an appreciation of the variety of their composite structures, as well as an awareness of their increasing role in sustainable development. The example in this article summarizes a carbon footprint accounting of a geosynthetic erosion control application with comparison to a hard armor concrete competitive erosion control product. More examples are available that provide even more of a pronounced carbon benefit when compost or natural fiber matrices are employed in rolled erosion control products. Such innovative products play an important role in the continued need for sustainable development achievement and the associated environmental care.
