Developing Sawdust into Decorative Pieces

Abstract

This study investigated the potential of transforming sawdust waste into decorative keychains using resin as a binding material, focusing on material optimization, production challenges, and product acceptability. Conducted at Cebu Technological University, the research was guided by principles of sustainability and waste utilization to reduce environmental impact while producing functional items. A mixed-method approach was used, combining experimental and descriptive survey designs. The experimental phase determined the most effective sawdust-to-resin ratio in terms of strength, finish, and cost efficiency. The descriptive phase assessed product acceptability among students based on appearance, durability, functionality, environmental value, and marketability. Results showed that the 60:40 sawdust-to-resin ratio produced the best outcome, offering strong bonding, smooth texture, and balanced cost. Production challenges included curing time, air bubbles, and mixing inconsistencies, while resin contributed significantly to production cost. Overall, respondents rated the product as highly acceptable across all criteria.

Introduction

The study explores the transformation of sawdust—an abundant woodworking waste—into eco-friendly decorative keychains using resin as a binding material. Sawdust is typically discarded despite being useful in products like briquettes or particle boards, and its improper disposal contributes to environmental pollution and health risks. The research proposes an alternative approach that repurposes sawdust into value-added crafts, supporting sustainability, waste reduction, and potential economic benefits.

The study is motivated by environmental concerns such as air and soil pollution, increased carbon emissions, and health hazards caused by unmanaged wood dust. It is grounded in waste management theory, emphasizing reuse and recycling of industrial by-products to reduce environmental impact. By converting sawdust into decorative products, the project aims to promote cleaner production practices and resource efficiency, particularly within woodworking shops at Cebu Technological University.

Methodologically, the study uses an experimental design to determine the ideal sawdust–resin ratio and evaluates product quality based on appearance, durability, functionality, and acceptability among 30 student respondents. The scope is limited to small-scale production, with constraints related to material consistency, curing conditions, and sample size.

Conclusion

Based on the findings of the study, it can be concluded that sawdust can be successfully developed into decorative pieces such as keychains using resin as a binding material. The study confirmed that the ratio of sawdust and resin plays a significant role in determining the quality of the product. The 60:40 ratio was found to be the most ideal, as it provides a balance between durability, appearance, and cost efficiency. Although the production process faced challenges such as curing time, mixing difficulties, and cost of materials, these issues can be managed through proper techniques and planning. Despite these limitations, the product showed strong acceptability among respondents. Furthermore, the study highlights the potential of sawdust as an alternative material for decorative products. It contributes to waste reduction, promotes sustainability, and provides an opportunity for innovation in woodworking practices.
