Biodegradable Geotextile
A biodegradable geotextile is designed to break down naturally over time through biological processes. Unlike conventional geotextiles manufactured from synthetic materials, biodegradable geotextiles utilize organic or natural materials capable of decomposition.
Advantages
While biodegradable geotextiles offer an environmentally friendly alternative to conventional geotextiles they have a shorter lifespan. Their benefits include:
Offer Environmental Benefits – Biodegradable geotextiles offer more environmental benefits in comparison with synthetic geotextiles as they decompose reducing waste accumulation.
Decomposition Improve Soil – Decomposition of these geotextiles can enhance soil nutrition by the addition of organic matter and promotion of microbial activity.
Decompose Overtime – Since they’re biodegradable they can degrade and decompose over time when exposed to environmental conditions.
No Need for Removal – These geotextiles eliminate the need for removal after their functional lifespan reducing maintenance efforts and related costs.
Offer Better Stabilization – They offer decent stabilization and erosion control performance during their functional lifespan displaying sufficient strength and durability.
Composition and Structure
Biodegradable geotextiles are made from natural materials like straw, jute, wood and coconut fibers and thus environmentally friendly. After extracting fibers from these plant materials, they are woven or mechanically bonded into fabrics.
Jute and coconut fibre have strong open structures whereas straw and wood fiber offer good permeability and strength performance respectively. Addition of natural binders like latex may be necessary to improve cohesion and material stability.
Uses
Biodegradable geotextiles are used to stabilize slopes, embankments, and other vulnerable areas where erosion is a concern.
Biodegradable geotextiles find use in the separation of fine particles from water allowing passage of water while retaining soil particles.
These geotextiles can be utilized where there’s need for control of sediment movement like in shorelines, construction sites or riverbanks.
They can offer temporary soil stabilization during construction, reinforcing weak or loose soils by distributing loads.
Applications requiring short-term functionality such as land restoration, construction projects and re-vegetation efforts utilize these bags eliminating need for removal.
