【中/英】廢玻璃容器回收再利用的多元面貌

【EN】Multiple uses for recycled waste glass containers

你可曾想過當我們將回收的玻璃瓶罐交付給資源回收車或回收站後,究竟它們去了哪裡?廢玻璃容器會經過怎麼樣的回收流程,又會變身成怎樣?

Have you ever thought about what happens to the glass bottles we take to the recycling truck or recycling station? What kinds of recycling processes will those waste glass containers go through and what will they become?

分類分色提升再生粒料附加價值!

Sorting and color separation to enhance the added value of recycled pellets!

This is followed by the removal of ferrous metals by electromagnetic separation. Then it is crushed, washed to remove organic matter, sieved through a vibrating screen, and finally glass pellets are produced.

廢玻璃的主要來源有平板玻璃、容器玻璃、汽車玻璃照明燈管及映像管等,其中最適合再生利用的廢玻璃種類就屬容器玻璃!因為它安全穩定、不具毒性且不會與其他材料起作用的特性,在生活中經常被用來作為液體容器,例如啤酒、飲料、料理酒、化妝品等等,而這些你我所熟悉的玻璃瓶罐,在進行分類分色時一般被分為茶色、綠色、透明共三類;沒有分色或分色不佳的才會成為雜色料(又稱綜合色料)。

The primary sources of waste glass are flat glass, container glass, automobile glass, light bulbs and tubes, CRTs, etc. The most suitable type of waste for recycling is container glass due to its safe, stable and non-toxic and inert characteristics. It is commonly used for producing liquid containers, such as beer, beverages, cooking wine, cosmetics, etc., and these glass bottles and jars that you are familiar with are generally classified into three color categories during sorting: dark-brown, green, and transparent. Without color separation or in the case of poor color separation, the glass will end up as a composite glass colorant (also known as an integral glass colorant).

其實市面上各式玻璃瓶罐的成分並無太大差異,會進行分類分色是為了確保最後產出的玻璃砂具有顏色單一性,能適用於一般玻璃的窯爐,藉此提升再利用管道的多元性,避免這些能夠百分之百被利用的再生粒料,因再利用管道受阻而堆積如山。

In fact, there is not much difference in the composition of the various types of glass bottles on the market. The separation process is carried out to ensure that the glass sand produced has a single color and can be utilized in general glass furnaces, thereby increasing the diversity of reuse channels and avoiding the situation where the regenerated pellets  pile up again as waste material due to narrow usage channels.

因此,為提升玻璃砂的附加價值,建議民眾進行玻璃瓶罐回收時,除了可先將瓶蓋卸下並將瓶身清洗乾淨、晾乾,避免油脂、調味料或化學物質的殘留外,正確的顏色分類也能提升廢玻璃回收的品質。

Therefore, in order to enhance the added value of glass sand, it is recommended that when we recycle glass bottles, we should remove the bottle cap and rinse and dry the bottles to remove residues from grease, seasoning, or chemicals. Proper color sorting can also improve the quality of waste glass recycling.

生活中的每個角落,都能看見廢玻璃再利用的應用

The applications of recycled waste glass materials can be seen in all aspects of daily life

廢玻璃容器再利用包含成品及半成品,半成品如亮彩琉璃;成品如地磚、再生建材、玻璃纖維、化學吸附劑、玻璃瀝青及人造大理石等。通常是依據再生粒料的品質決定其用途,較粗糙的作為瀝青、輕質骨材、水泥連鎖磚、玻璃紅磚等建材配料。較細緻的用於陶瓷釉料,或是直接做成容器、平板玻璃成品等,而最頂級的再生品質則能成為亮彩琉璃。

The recycling of waste glass containers includes finished and semi-finished products. Semi-finished products include colored glaze glass, and finished products include floor tiles, regenerated building materials, glass fibers, chemical adsorbents, glassphalt, artificial marble, etc. The applications are usually determined according to the quality of the regenerated pellets. The coarse glass pellets are used as building materials for glassphalt, lightweight frame materials, cement bricks, interlocking bricks, red glass bricks, etc. The fine glass pellets are used for ceramic glaze or made directly into containers, flat glass products, etc. The top quality regenerated glass is made into colored glaze glass.

每年回收一億公斤廢玻璃的春池玻璃認為,循環經濟應是將廢棄物「升級」再製,而非「降級」利用,「亮彩琉璃」便是一例,視覺上它璀璨繽紛,材質也比大理石硬、比花崗岩亮、吸水率近乎零,而且當中鍶與鋇元素還能阻隔紫外線、膨脹係數低而老化速度慢,非常適合用來拼貼建築牆面,作為公共藝術、庭園步道、泳池周邊、園藝盆栽的材料,從廢棄玻璃一躍而為琉璃藝術品。

Spring Pool Glass Industrial Co. Ltd, which recycles 100 million kilograms of waste glass every year, believes that the circular economy should be “upgraded” and waste materials be reprocessed rather than being “downgraded.” The “colored glaze glass” is one example of upgrading waste glass, transforming it into displays of colored glazed glass artworks. The material is even harder than marble, brighter than granite, has a near-zero water absorption rate, and its strontium and barium elements are capable of blocking UV rays. It also features a low expansion coefficient and low degradability, making it an ideal material for patchwork walls, public artworks, garden trails, poolside decorations, garden pots, etc.

相較塑膠容器總類及成分多元,在面對回收處理的高溫熔融時,容易產生劣化現象,只能降級再利用。而廢棄玻璃是一種可以完全回收再利用的材料,其主要成分以二氧化矽(SiO2)為主,與一般砂石相同。因此,回收的廢玻璃經加工處理後,其玻璃再生粒料(俗稱玻璃砂),便可以適當地取代一般路面所需添加的部分砂石,成為「玻璃瀝青」,或是製成各式玻璃地磚、圍牆磚、透水磚等運用於道路及景觀的環保建材。回收廢玻璃容器,減少天然資源的消耗,實踐環境保護「回收再利用」的永續概念!

The diversified range of compositions of plastic containers tend to deteriorate during the high-temperature melting process of recycling, which means they can only be degraded and reused. In contrast, waste glass is a material that can be completely recycled and reused. Its main component, silicon dioxide (SiO2), is similar to general sandstone. After waste glass recycling, the regenerated glass pellets (commonly known as glass sand) can appropriately replace some of the sandstone added to the general road surface as “glassphalt,” or they can be made into various types of glass such as floor tiles, wall tiles, porous bricks, environmentally friendly building materials for roads and landscapes, etc. Recycling waste glass containers can reduce the consumption of natural resources and fulfill the sustainable concept of environmental protection through “recycling and reuse.”
