Engineered media applications
Coco coir for stormwater bioretention.
A renewable coconut-husk material with potential as a functional amendment in stormwater biofilters, rain gardens, bioswales and other nature-based treatment systems.

Why coir
A practical organic fraction for engineered filtration media.
Bioretention systems slow and filter runoff through planted, engineered media. Coconut coir—available as fibre, pith or graded blends—has been studied globally as a natural amendment because of its porous structure, moisture-management characteristics and potential interactions with dissolved contaminants.
For technical projects, coir is not a standalone treatment claim. Suitability depends on the complete media blend, hydraulic design, vegetation, site conditions and laboratory acceptance testing.
02 · CONSISTENT INPUT
Process-controlled supply
Particle sizing, rinsing, buffering, moisture and compression can be aligned with a buyer’s specification.
03 · RENEWABLE FEEDSTOCK
Coconut-derived material
Coco pith uses material from coconut processing and can replace part of a specified organic fraction.
Coir capabilities
What coconut coir can contribute.
Research from multiple stormwater markets has evaluated coconut coir fibre and coir-based media in biofilters, vegetated columns and multimedia filtration systems.
The opportunity is not a universal recipe. It is a controlled coir input selected for the hydraulic, chemical and biological needs of each treatment system.
PHYSICAL FUNCTION
Porosity and moisture management
Coir’s fibrous structure can add pore space and moisture-holding capacity when engineered alongside mineral media.
TREATMENT POTENTIAL
Surface for sorption and biofilms
Published studies have examined coir for metals sorption and as a surface that can support biological treatment processes.
CIRCULAR MATERIAL
Renewable coconut feedstock
Coir converts coconut-husk processing material into a useful input for nature-based water infrastructure.
Design and validation remain project-specific.
Stormwater chemistry, pH, dissolved organic matter, salinity, flow rate, particle grading, contact time and the surrounding media all influence performance. Representative testing under realistic conditions is essential before field adoption.
Custom-spec pathway
From buyer specification to project-ready supply.
STEP 01
Review the specification
Share the intended system, target coir function, particle range, packaging, quantity, test methods and destination.
STEP 02
Define the coir input
Align washing, buffering, moisture, fibre-to-pith ratio, screening and format with the intended media design.
STEP 03
Validate before approval
Coordinate representative-sample testing with a qualified laboratory against project acceptance criteria.
Capability positioning: Avee is exploring custom-spec coir supply for stormwater and nature-based treatment applications. Performance depends on the complete system and must be established through project-specific design, representative testing and regulatory review. This page does not claim certification or guaranteed treatment performance.
