據了解,通過拆解后的不同類別的家具廢料,在回收市場會分別被相應的攤位回收,并送往各自需要的渠道,真正必須焚燒或者填埋的非常少,甚至不到1%。
回收市場作為一個平臺,除了完成拆解工作外,還會將同種類的廢舊材料打包,比如金屬材料會通過金屬剪切機統一剪成相應的尺寸,再由金屬壓塊機壓成同樣大小的塊狀,便于在送往鋼廠的過程中搬運和稱重;海綿、布料也會分別包成一袋一袋的;木質材料在去除五金配件后,也會將大小材質差不多的板材放到一起打包。
這其中,被運走的木質材料分為兩種,實木材料就直接送往一些家具廠,大件的實木可以直接再利用做成小件的家具,具體只需要去除一下表面的油漆即可;非實木多為人工板材,包括膠合板、刨花、纖維板等。據中國木材節約發展中心總工程師陶以明介紹,人造板因為本身就是由膠粘劑粘成的,其中還含有甲醛類的物質,處理起來就相對麻煩。需要先粉碎成顆粒,將原來加進去的膠取出來,所以處理的成本會高一些,但打碎后一樣可以再做成新的人造板,處理過程如果控制嚴格也不會造成污染。
至于危險廢料,陶以明表示,木制品家具里的危廢并不多,比如有些人造木材里面加防腐劑、防蟲劑等,這些物質里一般會含有重金屬,所以處理時如果直接燃燒,必然會污染空氣,必須粉碎后再次利用,以減少對環境的污染。另外,家具表面的油漆里面可能會有苯、甲醛等,也需要做同樣的處理。Learned, after dismantling the furniture of different categories of waste, and the market will be the corresponding respectively in recycling stall recovery, and sent to the respective needs of channels, really have to burn or bury very few, even less than 1%.
Recycling market as a platform, in addition to the complete dismantling work, also will be the same kind of waste packaging materials, such as metal materials will be through the metal shearing machine cut into appropriate size, again by metal press pressure into the same size of the block, facilitate to the steel mill in the process of handling and weighing; Sponge, cloth, also can respectively pack into a bag of a bag; Woodiness material after removal of hardware accessories, can also with packaging material similar to the size of the plate together.
In that shipped the woodiness material is divided into two kinds, real wood material is directly sent to some of the furniture factory, bulk solid wood can direct reuse of small furniture, specific you just need to get rid of the surface paint. The solid wood for artificial plate, including plywood, wood shavings, fiberboard, etc. According to the development of Chinese timber saving center chief engineer of the tao to Ming, man-made board because itself is made up of a adhesive glue, which also contains formaldehyde class material, is relatively complicated to handle. Need to smash into particles, the original add glue out, so the processing cost will be higher, but after the break can make new man-made board, strict process if control don't cause pollution.
As for hazardous waste, tao yiming, said the waste in the wood furniture is not much, such as some artificial wood preservatives, pest control, etc., these substances generally contain heavy metals, so if direct combustion, when processing will pollute the air, must use again, after crushing in order to reduce pollution to the environment. In addition, the paint on the surface of the furniture inside may have such as benzene, formaldehyde, also need to do the same.
