What is the coir fiber lifetime? Could it be recycled?
The coir fiber can be recycled after having been used for its initial purpose. It is an organic material that have positive benefits even after its used in the crop. It has been proved that the coir fiber reusing release beneficial microbes that are present in the medium, such as mycorrhiza and trichoderma. These compounds spread greater potential for growth enhancement over long periods of time.
Its lifetime depends on various factors as the type of coir used or its granulometry. These aspects will determine the prolongation of the coir fiber lifetime. Regarding the coir fiber granulometry, a higher percentage of coir chips in the mixture will contribute to a slower degradation of the substrate and therefore to a longer useful life. On the other side, sometimes the conditioning factor is the type of cultivation. There are crops such as blueberries in which it is interesting to maintain the coir fiber for more than 5 years. Others, as horticultural crops, do not need such a long duration.
In any case, after the end of the use for which the coir fiber was initially purchased, it can be managed together with other plant residues to be composted, applied directly to the growing soil or mixed with other substrates. It is a solution for giving it a new use thus avoiding the management problems of other products as the synthetic substrates.
It is also essential to recycle the plastic with which the coir fiber is supplied to a better environmental management.
