Traditional space bags use sawdust as a substrate. In line with the goal of green production and a circular economy, after research and development, the raw materials have been switched to plants from the Poaceae family, such as buffalo grass, Pangola grass, and sorghum, as an alternative to sawdust. In 2020, in collaboration with the Industrial Technology Research Institute, waste bamboo shavings were used for mushroom cultivation, replacing 70% of the sawdust in the entire space bag. 

Additionally, the waste space bag post-cultivation is handed over to feed mills for processing, serving as feed for the dairy industry. Mushrooms contain rich polysaccharides and functional ingredients, and it is anticipated that dairy or meat products produced by cows and sheep after consuming them will also contain similar functional components, benefiting consumers when ingested. This practice aligns with SDG 2 - Zero Hunger: Ensure food security, end hunger, and promote sustainable agriculture.
