Karakteristik Limbah Baglog Produksi Kulit Sintetis Miselium Jamur (Mylea) Sebagai Bioenergi

The concept of sustainability is widely used by industry to save the environment by minimizing waste and using environmentally friendly raw materials to manage used products. One of the companies in Indonesia carries the theme of sustainability to produce synthetic leather made from mushroom mycelium called Mycelium Leather (Mylea). Each production stage produces waste, one of which is baglog waste, a medium for mushroom mycelium growth. It is important to recycle this waste into more valuable products, for example, bioenergy. This study aimed to measure Mylea waste characteristics and see its potential as bioenergy. The stages of the research included taking waste samples of fresh and used baglog from Mylea production and testing characteristics, consisting of calorific value, ultimate (carbon, hydrogen, and nitrogen), sulphur and proximate content (moisture, ash, volatile matter, and fixed carbon). The results of fresh and used baglog tests for calorific values were 3,777.93 cal/g and 3,710.98 cal/g; carbon 39.67% & 39.75%; hydrogen 6.70% & 6.65%; nitrogen 0.82% & 0.83%; sulphur 0.19% & 0.13%; moisture 12.80% & 12.56%; ash 3.5% & 4.27%; volatile matter 81.81% & 79.88%; fixed carbon 14.62% & 15.85%. Based on these results, Mylea baglog waste biomass still has low quality and needs to meet the standards to be used as solid fuel. Improving the quality of baglog waste can be done by briquetting. Baglog waste biomass with low results will be more effective for liquid fuels such as bio-oil.
