Abstract
Paddy straw, abundantly produced in northern India is stacked in the field after its harvest. Financial liability to clear straw from their field for next crop forces farmers to take desperate decision to resort to open field burning causing severe air pollution. Global climate change also has catastrophic impact on the built environment in the form of incessant rains to cause erosion of slopes of newly built embankments. Control of erosion of such slopes would increase security and safety of the infrastructure. In the present work, paddy straw is used as an alternative to high ended materials, like jute and coir, to manufacture rolled erosion control products (RECP). The claim of paddy straw is justified since it has same chemical composition as that of jute and coir. Thus using IS15868 part 1 to 6, a mesh type rolled erosion control product (RECP), made from stems of paddy straw, using handmade technique and labelled as 6PSG-12 (12 referring to aperture size in mm) is proposed [1]. Paddy straw geomesh (6PSG-12) was tested and found to possess important index properties, like tensile strength, drapability and durability. Similarly bench scale testing has confirmed effectiveness of 6PSG-12 in controlling slope erosion in the field.
