Coir fiber logs are biodegradable logs or biologs (decomposed ground coconut husks pulp) which are tightly packed in tubular netting. They are 100% natural materials, excellent planting medium additives which add fertility to the soil after biodegradation, high tensile strength, high water absorbency, eco-friendly, and wildlife safe.
Coco coir biologs can be made in variety of lengths and densities to suit different applications. As the logs can absorb large amount of water, the logs can be used to slow down the velocity of storm water run-off, thus stabilizing slopes. They are great for shorelines/river embankment stabilization and forest slope rehabilitation. It also provides bedding where the seedlings and/or cuttings are inserted into logs with sediment. As the coconut fiber logs biodegrade, the plants develop a well-established root system in the shoreline sediment to retain the soil in place. Moreover, the logs are useful in catch basin protection, keeping unwanted pollutants from entering into sewer systems.
For maximum utilization of coco coir, the MIRDC developed a manual machine for coco coir biologs that compresses coco fibers while encapsulating it in a geotextile net, the so-called coir fiber biologs. The machine measures 3000 mm x 1030 mm x 502 mm and capable of producing 30 units of coco fiber biologs per day even by a novice operator. The manufacturing cost of the machine is approximately P40,000.00.
The machine for coco coir biologs is a promising technology for coir fiber since the Philippines is among the top coconut-producing countries. With this machine, it will not only generate employment for coco processors but also increase the utilization of coconut coir for commercial purposes.
