Degradable plastic

Oxo-degradable plastics, just like conventional plastic materials, are still made of petroleum-based polymers. The only difference in property is that it contains chemical additives which allow the plastic to break down quicker than it normally would in presence of oxygen, heat and light. However, these products don’t disintegrate at molecular or polymer level like biodegradable and compostable plastics. Instead, they simply fragment into smaller pieces and eventually become #microplastics🌬left in the environment indefinitely. 與傳統塑膠一樣,「氧化式可分解」塑膠都係以石油基聚合物製成,唯一分別係佢加左化學添加劑改變塑料特性,令塑膠係陽光、熱能同氧氣充足嘅環境底下更快咁分解。但佢地唔會好似生物塑料咁被微生物降解,相反地,佢地會慢慢將聚合物分解成細碎片,變成無限期留係環境裡面嘅#微塑膠 。 . Oxo-degradable plastic bags & packaging are often marketed as a better alternative for the planet, implying a reduced environmental impact after disposal compared to traditional plastics without additives - but are they really? It’s common that people get confused over the difference plastic terminologies - ‘degradable’, ‘biodegradable’, ‘compostable’, ‘PLA plastic’ etc. Something that sounds great in theory can be environmentally destructive in reality. Especially when environmental awareness and demand for sustainable products are on the rise, as consumers we should develop our understanding of these plastic terms in order to make well-thought-out purchasing decisions and properly dispose of plastic products at the end of use. 「可分解」塑料包裝有時會被用為環保嘅銷售策略 ,強調着塑膠被丟棄後對環境嘅影響更小 - 但事實係咪咁呢?塑料種類太多而且資訊都很雜亂,很多人都對「可分解」、「可生物降解」、「可堆肥」、「PLA塑膠」等字眼感到難以理解。聽落好似很環保嘅方案係現實執行中可能又係另一回事。尤其係當大家嘅環保意識同對可持續產品嘅需求逐漸增加時,作為消費者嘅我地更應該嘗試理解不同嘅塑料種類,以便做出深思熟慮嘅購買決定,並可以妥善處理用完嘅塑膠類產品。

The labelling (or no-labelling) or plastic products can be confusing and misleading, so remember ‘Bring Your Own’ is always the best option. Make it a habit to refuse single-use plastics whenever you can; the little steps do help! 塑料產品上嘅標籤(或冇標籤嘅塑膠)可能令人感到困惑或有誤導成份,所以記住「自備」永遠係最好嘅選擇。養成盡可能拒絕使用一次性塑膠嘅小習慣啦!
