English
This study investigates the use of food waste (hazelnut shells, pistachio shells, date seeds, avocado pits, mango pits, tea leaves, brewing waste) as fillers in bio-composite façade cladding. The materials were processed into fine powders and combined with a furan-based biobased resin. Mechanical testing, water absorption, and freeze-thaw durability tests show that hazelnut and pistachio shells produce composites with flexural strengths up to 62.6 MPa and impact strengths up to 3.42 kJ/m², demonstrating potential as low-carbon cladding alternatives.

日本のGX文脈において
日本では建設分野のライフサイクルカーボン削減が急務であり、'ライフサイクルカーボン算定ガイドライン'の策定が進む。食品廃棄物を活用した低炭素外装材の技術実証は、サプライチェーン上のScope3排出削減や循環経済の実装に寄与する可能性がある。
In the global GX context
Globally, the construction sector accounts for ~40% of CO2 emissions, with façades contributing 15-20% of embodied carbon. This paper offers a circular material solution that could reduce reliance on carbon-intensive cladding materials like aluminum and FRPs. It aligns with circular economy principles and net-zero building targets.

📄 Abstract（原文）
Façades account for approximately 15–20% of a building’s embodied carbon, making them a key target for material decarbonization. While bio-composites are increasingly explored for façade insulation, cladding systems remain dominated by carbon-intensive materials such as aluminum and fiber-reinforced polymers (FRPs). This paper presents findings from a study investigating the use of food-waste-derived bulk fillers in bio-composite materials for façade cladding applications. Several food-waste streams, including hazelnut and pistachio shells, date seeds, avocado and mango pits, tea leaves, and brewing waste, were processed into fine powders (<0.125 μm) and combined with a furan-based biobased thermoset resin to produce flat composite sheets. The samples were evaluated through mechanical testing (flexural strength, stiffness, and impact resistance), water absorption, freeze–thaw durability, and optical microscopy to assess microstructural characteristics before and after testing. The results reveal substantial performance differences between waste streams. In particular, hazelnut and pistachio shell fillers produced bio-composites suitable for façade cladding, achieving flexural strengths of 62.6 MPa and 53.6 MPa and impact strengths of 3.42 kJ/m2 and 1.39 kJ/m2, respectively. These findings demonstrate the potential of food-waste-based bio-composites as low-carbon façade cladding materials and highlight future opportunities for optimization of processing, supply chains, and material design.
