Green Science Alliance Has Developed Plant Based Biodegradable Filament (PLA + Cellulose Nanofiber) for 3D Printer
KAWANISHI-CITY, Japan, May 30, 2024 /PRNewswire/ -- Environmental problems such as climate change, global warming, deforestation, extinction of species, water shortage etc... due to explosion of human population are becoming increasingly severe worldwide. Plastic pollution is also a severe environmental problem which cause adverse effects, especially nanoplastics which are already present in the human body as a result of plastic polluted breathing air and though our meal. For example, we are ingesting nanoplastics through drinking water with PET bottle. Recently, there are some medical studies reporting the enhanced risk of heart attack, stroke caused by nanoplastics in blood vessels. In addition, they may also possess ill effect for the immune system as well as cause inflammation reaction in digestive system.
日本川西市，2024年5月30日 /PRNewswire/ — 由於人口爆炸造成的氣候變化、全球變暖、森林砍伐、物種滅絕、水資源短缺等環境問題在全球範圍內變得越來越嚴重。塑料污染也是一個嚴重的環境問題，會造成不利影響，尤其是納米塑料，由於塑料污染了呼吸空氣和我們的膳食，這些納米塑料已經存在於人體中。例如，我們通過飲用水和 PET 瓶攝取納米塑料。最近，有一些醫學研究報告說，血管中的納米塑料引起的心臟病發作和中風的風險增加。此外，它們還可能對免疫系統產生不良影響，並引起消化系統的炎症反應。
The production and usage of biodegradable plastic is slowly increasing, although greater than 90 % of plastics worldwide are still petroleum-based non-biodegradable plastics. In addition, the production of this petroleum-based non-biodegradable plastics are still increasing regardless of these plastic pollution problems. Therefore, plastic pollution is worsening each year.
儘管全球超過90％的塑料仍然是石油基不可生物降解的塑料，但可生物降解塑料的生產和使用正在緩慢增加。此外，儘管存在這些塑料污染問題，這種石油基不可生物降解塑料的產量仍在增加。因此，塑料污染每年都在惡化。
On the other hand, biodegradable plastics can biodegrade and return back to nature and do not become plastic pollution although biodegradability needs to be carefully examined in various types of conditions including compost condition, soil, water, sea water etc. However, biodegradable plastics including PLA (polylactic acid), lactone based materials are already applied for medical usage in human body.
另一方面，儘管需要仔細檢查各種條件下的生物降解性，包括堆肥狀況、土壤、水、海水等，但可生物降解的塑料可以生物降解並回歸自然，不會成爲塑料污染。但是，包括聚乳酸（聚乳酸）在內的可生物降解塑料已經應用於人體醫療用途。
Under this circumstances, Mr. Daiki Tanaka and Mr. Hirohisa Iwabayashi as Ph.D candidate at Green Science Alliance have developed biodegradable resin filament for 3D printer with PLA and cellulose nanofiber composite. The company is selling these products also on online shop ( They also confirmed that biodegradability and mechanical strength have been strengthened when cellulose nanofiber concentration is high enough in base PLA resin. They also developed plant derived cellulose based biodegradable resin filament for 3D printer although this still has problems regarding printability and adhesion. Therefore, they began selling PLA + nanocellulose composite biodegradable filament first. The company will keep working for improving various types of biodegradable resin filament and colored filament too, for 3D printer market demands.
在這種情況下，田中大樹先生和巖林宏久先生作爲綠色科學聯盟的博士候選人，已經開發了使用聚乳酸和纖維素納米纖維複合材料的三維打印機用可生物降解的樹脂燈絲。該公司還在網上商店銷售這些產品（他們還證實，當基礎聚乳酸樹脂中的纖維素納米纖維濃度足夠高時，生物降解性和機械強度就會得到加強。他們還爲3D打印機開發了植物衍生的纖維素基可生物降解樹脂燈絲，儘管這在可打印性和附着力方面仍然存在問題。因此，他們首先開始銷售PLA +納米纖維素複合可生物降解的長絲。該公司將繼續努力改進各種類型的可生物降解樹脂長絲和彩色燈絲，以滿足3D打印機的市場需求。
