南投竹產業的廢料新生
Rebirth of Bamboo Waste in Nantou’s Bamboo Industry
A.竹廢料與它的產地
南投是與竹共生的山林基地，也是臺灣竹產業復興的重要據點。這裡不僅孕育出職人技藝與工藝文化，更累積了豐厚的材料知識與產業鏈網絡。隨著竹產業的發展，南投每年產出各式形色不一的竹廢料，這些過去被視為無用的切屑與邊角，正透過地方企業的投入被重新定義。竹育股份有限公司長期與周邊竹產業合作，系統化回收並進行定性與定量的研發測試，將竹廢料製成可穩定應用的竹造粒，導入各類循環再利用產品中，讓竹子以嶄新的姿態重返生活，形塑綠色材料的完整循環路徑。
A.Bamboo Waste and Where to Find It
Nantou is a mountainous region that has long coexisted with bamboo—home to both Taiwan’s bamboo craftsmanship and its industry revival. Beyond nurturing artisanal skills and craft traditions, Nantou also carries deep material knowledge and an active production network. As the industry grows, it produces a wide variety of bamboo waste—offcuts and scraps once seen as worthless and now being redefined through local innovation.
Chu Yuh Co., Ltd. collaborates with surrounding bamboo producers to systematically collect, sort, and test bamboo waste. Through continuous testing and refinement, they turn discarded fragments into stable bamboo granules used in circular products—bringing bamboo back into daily life and shaping a complete green materials cycle.

B-1."Black Gold" of Carbon Credit Research on Bamboo Biochar
Biochar is a porous carbon material made by pyrolyzing biomass. Known for its long-term carbon storage, it is widely used in agriculture, construction, environmental applications, and craft. According to the European Biochar Certificate, it can also replace fossil carbon during production—making it a key material in the low-carbon era. This section presents bamboo biochar developed by Professor Wei-Shin Chen’s GenFuel Lab at National Cheng Kung University. Using patented low-temperature pyrolysis, the team transforms bamboo waste from Nantou—opening a new path for bamboo regeneration.
Common Applications of Biochar:
Soil enhancement and plant growth; Low-carbon green construction; Craft design and material innovation; Environmental remediation and pollution control; Emerging applications in energy storage and batteries.

閱讀手上的一把炭─工藝視角下的材質表情
生物炭根據用途的不同，會進行不同的性質分析。作為工藝材料時，會特別關注其顏色、質感、吸附性與穩定性等特性，以評估其是否適合用於塗料、複合媒材或成型物件等創作應用。除了視覺與觸感的表現外，生物炭本身的環保價值與低碳屬性，也讓它成為新世代永續工藝媒材的重要選擇。透過材質的實驗與搭配設計的創新，生物炭不僅是材料，更是與自然共生、訴說循環故事的創作基底。
Reading a Handful of Charcoal: Material Expressions Through the Lens of Craft
The properties of biochar vary depending on its intended use. When viewed through a craft lens, attention shifts to its color, texture, absorbency, and stability, which determine its suitability for use in coatings, composite materials, or molded forms. Beyond its visual and tactile appeal, biochar also holds environmental significance. Its low-carbon nature positions it as a compelling material for sustainable craft practices. Through material experimentation and design innovation, biochar becomes more than a medium—it is a co-creative agent with nature and a storyteller of circularity.
竹生物炭測試要點 Key Testing Points for Bamboo Biochar
1.會不會發霉？（水活性）
水活性0.5aw 以下較好，不會發霉 (一般食品規範不發霉要求標準為0.6 aw)
Will It Mold? (Water Activity)
Water activity below 0.5 aw is ideal and prevents mold growth. (The general food safety threshold to avoid mold is 0.6 aw.)
2.親水還是疏水？（接觸角）
水滴下去的瞬間，水滴與試體表面的角度呈現90度以下為「親水」、90度以上為「疏水」。
90度以下親水、90度以上疏水
Hydrophilic or Hydrophobic? (Contact Angle)
A surface is hydrophilic when the water contact angle is below 90°, and hydrophobic when above 90°.
