| Abstract | Strong typhoons strike the Philippines every year, and the amount of usable land is decreased by the loss of land properties from soil erosion. In recent years, geotechnical engineering has increasingly used biodegradable reinforcing materials. Since natural fibers are renewable, energy-efficient, and non-toxic raw materials, using them in these applications makes the solutions more sustainable. Using temporary, biodegradable geosynthetics to stop soil loss and promote the establishment of vegetation where the vegetation alone should provide adequate site protection once established is one of the solutions used nowadays to solve soil erosion problems. The characteristics and field performance of coating geotextile with lignin-based adhesive are discussed in this paper. The adhesive was created by mixing 70% Urea Formaldehyde resin, 10% water, and 20% calcium lignosulfonate. In a 3 feet by 2 feet scale model plot with clay soil from Tandang Kutyo, Rizal, on a 45 degree slope, coconet with and without lignin was laid out. Laboratory tests and statistical analysis were done to determine the product's suitability as an erosion control blanket material. A scale model for field setup was also used to assess the performance of coconet with lignin coating after weather exposure in terms of runoff and soil loss, degradation through tensile strength, and vegetation development. The average tensile strength per twine of lignin-coated, unexposed coconet measured in the laboratory was 222.92N, or almost 150 percent of the tensile strength of coconet sold commercially. Shapiro-Wilk Normality Test on tensile strength also shows that the tensile strength of coated and uncoated coconet were not normally distributed. The Mann-Whitney U-Test also demonstrated that there is at least 95% probability that the increase in strength is due to coating coconet with lignin-based adhesive. Coating coconet with lignin-based adhesive increased its mass per unit area, thickness, and lignin content |
