Trichoderma Viride-mediated Bioconversion: A Promising Approach for Recycling of Household Kitchen Waste

Abstract

Management of waste has become challenging issue for mankind to resolve. From diverse routes enormous quantities of waste are generated every day, the majority of waste is dumped on roadways, in open spaces, or near water bodies (such as streams, rivers, or drainage systems) or on the roadways, which is the main cause for polluting of the environment. Present study was designed to investigate different recycling approaches to remediate the kitchen waste into organic manure. Various experimental sets were designed to investigate the rate of decomposition of kitchen waste with different mixtures viz Set‑I (Kitchen waste:Dung), set‑II (Kitchen waste: Rice straw), Set‑III (Kitchen waste:Dung: Rice straw), Set‑IV (Kitchen waste:Dung+Trichoderma viride), Set‑V (Kitchen waste:Rice straw+Trichoderma viride) and Set‑V (Kitchen waste:Dung:Rice straw+Trichoderma viride). Results of the present study revealed that all the experimental sets showed ability to recycle the kitchen waste into organic manure. However significantly higher rate decomposition was observed in set-IV (KW: D+Trichoderma viride) such as change in physical features (color, odour, loss of weight and volume). Therefore, kitchen waste mixed with cow dung and Trichoderma was found to be the most suitable medium for the decomposition of kitchen waste. This method can be used for the recycling of other types of biodegradable waste to develop alternative organic fertilizer for agriculture purposes.
