塑膠興起在19世紀中，主要目的為取代越來越難取得的天然材料，科學家以不存在自然界分子組成完全合成聚合物，依仗著廉價、易塑形、防水和便利攜帶的優勢，快速度佔領生活中各角落，由於塑膠垃圾無法在自然環境中被分解，也造成生物誤食死亡和塑膠粒子流入食物鏈中，人類在食物鏈的最上層，終將是受傷最重的一層。
塑膠垃圾問題近年來備受關注，人們意識到此問題，開始找尋各種方式試圖解決，例如:海洋吸塵器、可分解塑膠的技術、廢塑膠煉解製油、以及定期舉辦淨灘活動，目前這些方法和技術都在驗證中，也無法全面性解決塑膠垃圾問題，主因歸咎於撿垃圾遠不及丟棄垃圾的速度，由此可知，人們減少拋棄式塑膠使用，才是解決塑膠垃圾問題的主要關鍵。為了解決塑膠垃圾問題，社會和人們需要更積極的作法，或行動方案，因此，本研究目的在於希望找出無塑生活實驗逹成的關鍵研究-以小事生活經營者為例，本研究採質性研究，個案訪談、觀察，以語音檔記錄，進行文字稿的撰寫，研究分析無塑逹人洪平珊的無塑生活實驗。本研究的問題及發現，第一、無塑生活實驗如何與個案生活產生連結關鍵在於，想要轉變、轉變契機、摸索無塑的可能性，第二、個案達成無塑生活的理念與做法，關鍵在於為自己而活、回歸自然、目視化管理和現地現物、持續獲得快樂，第三、個案如何克服在無塑生活實驗期間遇到的問題，關鍵在於轉念、自省、有所堅持、無塑能力提升。
本研究由訪談內容逐句分析其涵義，比較與研究相關問題和不斷歸納與分類，除了得知洪平珊進行無塑生活實驗的關鍵外，本研究提出「四心、三不、二信樂」理論，本研究的具體貢獻為透過此理論，讓人們可以更簡單的進入無塑生活。

Plastic was first invented in the 19th century to replace natural materials that were hard to get.
Scientists created polymer by combining molecules that don't exist in nature. Being low-cost, easy-to-shape, water resistant and convenient to carry, plastic has taken over every corner of our life. Because plastic is not biodegradable, if not disposed of properly can destroy nature. Animals that accidentally eat plastic die and plastic become part of the food chain. Humans will suffer the most being at the top of the food chain.

Plastic garbage has attracted more concern these years. People who have realized this problem began to search for solutions, for example, Ocean Cleanup Array, technology to break down plastic and extract oil from plastics, beach-cleaning movements that have been seen regularly. But these technologies and methods are still at the experimental stage and yet they can’t solve the plastic issue completely for the main reason that more garbage is thrown than can be disposed. Therefore, cutting down on the use of disposable plastic is the key to solving the issue of plastic garbage. People and society need to take more active measures, follow effective examples, revise their thoughts and face the challenge from themselves. The aim of this research is to explore the key to achieving plastic-free life by taking self-employed businessmen as examples. There are three major findings. First, the key to connecting plastic-free experiments with individual case lies in the willingness to change, opportunity for change and possibility of plastic-free life. Second, living for oneself, returning to nature, visual management, practical considerations, lasting pleasure are the thoughts leading the individual to a plastic-free life. Third, how the individual overcomes the problems arising from plastic-free living depends on his will, plastic-free self-reflection, persistence and the increase of his ability to live without plastics. This research takes qualitative approach to explore the factors conducive to Hong Pingshan’s plastic-free life by interviewing experts, making observations, voice and written records.

By analyzing interviews, comparing similar research issues and means of classification and categorization, this research finds that the key to non-plastic living can be concluded into “four beliefs, three don’ts, 2 pros”. Hopefully, this research can help people live without depending heavily on plastics.
