Wood Plastic Composite Material(also called “WPC”,“man-made Wood”,“Plastic Lumber”).It is with the thermoplastic resin and the natural fiber after the high polymer modification, with matches mixes, squeezes out one kind of compound material which the equipment processing makes. It has both the plastic and the lumber characteristic, may substitute them in many situations, the application domain is extremely widespread; the material to be allowed 100% recycling, is one kind conforms to the international initiative circulation economy environmental protection new material, thus extremely has the development potential.For the product of PERTH, 50% of the raw material are wood cellulose, 45 % are plastic( mainly HDPE/ (PVC and PP are used if requested for specific purpose) and the other 5 % are chemical addictives like colourants, stabilizers. This material retain some qualities of natural wood while new propeties such as waterproof and rot resistance are also developed.
塑木合成材料 簡稱 "WPC"或人造木。這是天然植物纖維及熱塑性塑膠經處理後的混合物,根據不同需要,可配合機器製造出不同形狀。該類產品同時擁有塑膠及木材的特性,適用於多種埸合。該物料能夠被完全回收循環再用或再製,是國際環保上一種具潛力的材料。該產品45% 是塑膠(主要為PE,根據顧客需要,會使用PP & PVC) 50% 木材纖維,其餘5% 是色素,穩定劑等材料。

Since the material can be produced by modeules together with easy installation and removal of the material, the material can be recycled and reuse to great extent. As mentioned before, the wood fibre in the product are bodegradable while the plastic used are not. The use of PVC also are toxic in some products ( not all products) give pollution to the enviroment. According to the manufacturer,since this material is a relatively new material so it is not easy to collect the used material now. However, The company have plan to introduce the reclamation programm in the future.該產品可模數化生產,產品能夠輕易安裝及拆卸,同時間拆卸後的材料大部份能再用或再製。在上文提及,該產品的植物纖細部份是生物可降解的,然而,塑膠部分(PP、PE、PVC) 則不可以,PVC 甚至會對環境造成破壞。根據製造商所說,該物料現時仍為市場上較新的物料,因此回收比較困難,但在將來,公司會嘗試採用回收計劃。
评论:
P.1 The raw material used are recycled wood/fibre and plastic from other factories/industries.These raw materials are post consumer recycled.Also, the used wood plastic composite product can still be recycled to give new one. 該產品的原料為從其他工廠或廢棄品回收的木材/纖維及塑膠,因此,該產品屬於後消費產品,而且,用過後的木膠合成產品仍可再使用或回收再造。
P.2 Since the raw material come from used material. The relatinships with natural resources consumption is indirect. Because of the use of used raw material. The use of this material replace the use of 'real' wood that reduce the use of original wood.The highly reusable quality of wood plastic composite reduce the use of original wood and hence provide more chance for the growth of wood/plants, though the impact is also indirect and not obvious.由於該產品的原材料是已用過的膠及木材纖維,該產品與開採天然資源的關係較為間接,同時,使用該產品能夠代替使用原木材。雖然影響較為間接,但增加使用可再用及再製的木膠合成材料卻能提供更多時間及空間給樹木生長。
P.3Since the raw materials are post consumer product, this avoid the extraction of petrol and original wood from the enviroment.由於原材料屬於後消費產品,這避免了重新提取天然原材料的過程。
P.5Since the material retain some properties with some improved qualities(such as waterproof) of traditional wood board but it can be recycled and reused many times. It reduce the use of original wood while still applicable for same purpose.Using this material reduce the use of original wood and the use of waterproof layer. 由於該材料保存了木材的某些特性以及混合塑膠後的一些新特性,例如防水性質,同時,它亦可循環便用,使用該材料減少了使用木材及其他防水防腐塗層
P.7In normal use, the product is not hazardous. However, this product may be cut or finished in ways which produce wood dust fibers. Certain wood fibers are considered hazardous if the airborne concentration exceeds the OSHA or ACGIH exposure limits for long periods of time. Exposure to such fibers is considered unlikely with this product; all sawdust in the board is fully stabilized in the plastic resin matrix. 在正常情況下,該產品是無害的。但是,該產品有可能被切割,這過程有可能產生微細木粉/纖維,有部份可能對人體有害。
P.8In the production process, may be there will be some wood dust and plastic remained as residue, these material can be recycled to the production line after collection.For the wood fibre, it is already organic material which is biodegradable. However, for the plastic,which constitute 45% material of the product, most of them are High density polyethylene_HDPE, poly propropylene_PP and Polyvinyl chloride PVC which are not biodegradable or even toxic. But the point is that all these plastic are recycled from factories, which reduce the impact of using them. 在製造過程中,有可能會製造多餘的木粉及塑膠原料,這些原料可以再投入生產線中作為原料。在這些原料中,植物纖維是生物可降解的,然而,佔產品45%的塑膠,都是PP、PE及PVC 等非生物可降解的材料。比較正面的是,工廠使用的材料大多是從其他工廠收購回來,減少了直接製造而形成的需求所帶來的影響。
