In the past, bamboo waste was sold to joss paper producers. However, as the paper industry moved offshore, bamboo waste has no place to go, resulting in a break in the industry chain. In order to properly handle the industrial waste, ITRI has set up a strategic program that includes developing technology to reuse bamboo waste as a substrate for mushroom cultivation, and working with mushroom producers. It has been confirmed that adding 40% bamboo shavings to the growing medium for king trumpet mushrooms can increase growth rate by 11% and annual revenue of the mushroom producer by 10%.
In addition, ITRI helps biofuel producers build factories which can produce 48,000 tons of bio-fuel annually by converting waste mushroom compost bags into biofuel. This biofuel features high heat value, low sulfur oxide (SOx) proportion, low nitrogen oxide (NOx) proportion, and zero carbon emission. Analysis has shown that one ton of this biofuel can produce 5.7 tons of steam, creating a profit of NT$190 million and a carbon reduction of 310,000 tons annually. Building an industry chain for bamboo waste reused as mushroom cultivation substrate and biofuel can establish a new circular economy and a new cooperation model for the bamboo, mushroom, and energy industries, as well as reuse waste materials for the most economic benefits.
