COCOAURA – Fragrance, Nature’s Way

COCOAURA, an organic car freshener, was developed as a natural alternative to traditional chemical air fresheners. It is meticulously crafted from coir pith and fibre, natural materials sourced from coconut husk, and provides a safe, chemical-free way to energise interior areas. Even after the product's usable life expires, the used coir pith and fibre may find a second life enhancing gardening soil. The product is incredibly eco-friendly and produces no waste during manufacture. COCOAURA has antibacterial and antifungal properties in addition to controlled release diffusion capabilities. There are five different ways to get COCOAURA: granulates, fibres, gel, sachets, and vent clips.

Development of chemical and biological system to treat ret liquor

In the process of coir fiber extraction from coconut husks, the traditional method of retting, involving soaking the husks in water, is time-consuming and generates retted water as a by-product. Discharging this water improperly can lead to pollution. Mechanical extraction of coir fiber is a quicker alternative, but it results in bright-colored fiber that can oxidize and become brown and coarse. Soaking the fiber for 24 hours after defibring helps reduce lightfastness and improves texture. The washed water from this process, known as ret liquor, is brown due to the organic matter present and can be harmful if released into water bodies.

The study also explores the use of biological treatment using fermenters. A double-chambered fermenter design showed a reduction in BOD (Biological Oxygen Demand) of ret liquor. The system employs a mixture of cow dung slurry, cheese whey, and effluent from the paper industry as a source of bio-inoculum for anaerobic digestion of coir ret effluent, followed by filtration through coconut shell pieces. This treatment method holds promise for further analysis and standardization of inoculum sources and treated water quality.

Treatment of coir fibre with various biological and chemical agents to improve the texture and colour.

This study focuses a combined treatment (chemical and biological), that have a great potential to produce more consistent quality fibres with substantially reduced retting time and is more environmental friendly. To improve the coir fibre texture, trial experiments were conducted with a chemical softener developed by NCRMI.

Value addition of coir ret liquor with chemical methods

Soaking coconut husk in brackish water system for 6- 12 months is an old traditional practice carried out for the extraction of coir fibre from coconut husk. As a result of retting large quantities of organic substances including pectin, pentosan, fat, tannins, and also toxic phenols are liberated into water. All these processes contribute to pollution of water and air. This is reported to have devastating effect on the flora and fauna. This study focuses a combined chemical and biological methods should be environment friendly and economically viable treatment on ret liquor collected from various coir spinning societies.
