隨著單身、少子及老齡化等社會趨勢的發展，寵物貓已成為許多人的的情感支持，甚至被視為家庭的一部分。深厚的情感依附關係不僅有助緩解飼主的壓力與孤獨感，同時也推動了寵物產業的蓬勃發展。隨此趨勢，寵物市場從小眾市場逐步擴張至規模經濟，進一步驅動寵物用品多元化的需求。然而，寵物用品廣泛使用塑料等難以回收材料製造，不僅為生態系統帶來威脅，或將影響寵物健康。近年來，隨著消費者對於可持續性的重視，寵物產業愈發關注品牌、自然環境與社會的永續發展。許多品牌嘗試在產品設計與生產中引入可回收或可再生降解材料，以降低資源的耗損以及環境的破壞。此外，品牌還透過建立可持續的封閉循環系統，藉此促進資源的重複利用，並減少廢棄物產生、降低原材料需求和能源使用，從而減少碳排放。
本創作旨在以循環材料為基礎，打造可永續發展的寵物貓用品。在初步研究階段，本創作對市場上常見寵物用品材料進行探索，最終選定以吸收性衛生用品再生長纖白紙漿作為本創作主要應用材料，並透過對紙漿材料應用案例的探討，加深對該材質特性之理解及彙整材料應用方法。接著，本創作引入循環設計策略，並整合案例探討結果及飼養經驗之觀察，發展符合循環設計原則及具差異化體驗的寵物貓用品設計概念。此外，本創作也為寵物貓用品設計概念. 建立一套資源循環架構，以促進資源有效應用及串連相關利害關係人，藉此推動寵物用品產業的循環經濟發展。
經由再生纖維實驗與設計實作，本創作最終產出三項寵物貓用品設計原型，分別為：Fur-ward，一款透過模組化結構實現簡易組裝和收納的永續貓隧道玩具；Scentery，一款為寵物貓提供豐富嗅覺刺激和遊戲體驗的永續嗅聞藏食玩具；以及ReGrowl，一款具有低耗材包裝、易於種植和可生物降解特性的貓草植栽組。本創作亦針對上述創作提出預期效益，以評估循環材料應用於寵物用品市場之影響與潛能。

In the face of societal shifts toward singledom, declining birth rates, and aging populations, pet cats have become emotional support for many, seen as family members. This trend has transformed the pet market from niche to scale economy, increasing demand for diverse pet products. However, the use of plastics in these products challenges recycling and causes ecological impact and potential pet health risks. Recently, consumer focus on sustainability has led the pet industry to prioritize brand, environmental, and social sustainability. Many brands now use recyclable or biodegradable materials in their products and employ sustainable closed-loop systems to promote resource reuse, reduce waste, minimize raw material and energy use, and lower carbon emissions.
The goal of this creation is to develop sustainable pet cat products using recycled materials. Initial research led to the selection of recycled-cellulose pulp from the Absorbent Hygiene Product (AHP) industry as the primary material. Case studies provided insights into the material's characteristics and application methods. Circular design strategies were then incorporated, reflecting case study findings and pet ownership insights. This approach yielded pet cat product concepts that aligned with circular design principles and provided unique experiences. The creation also introduced a resource recycling framework tailored to the product concepts, promoting resource efficiency and stakeholder engagement, advancing a circular economy within the pet product industry.
Experiments with recycled-cellulose pulp resulted in three sustainable pet cat product prototypes: "Fur-ward," an easily assembled, storable cat tunnel toy; "Scentery," a sensory-stimulating snuffle toy; and "ReGrowl," a low-material, easily cultivated, biodegradable catnip planting kit. Anticipated benefits were assessed for each innovation, highlighting the potential impact of circular materials in the pet product market.
