當前(qian)我國建(jian)(jian)筑(zhu)垃圾(ji)體量(liang)大，但利(li)用率不足10%，隨著天然砂資(zi)(zi)源的短(duan)缺和砂價的上漲，建(jian)(jian)筑(zhu)垃圾(ji)資(zi)(zi)源化(hua)利(li)用成為新的投資(zi)(zi)熱點(dian)，各地(di)紛紛促(cu)進(jin)建(jian)(jian)筑(zhu)垃圾(ji)循環再(zai)利(li)用。而在(zai)其處(chu)理過(guo)程中，移動破碎站因方便快捷、效益高等發揮(hui)著極其重要的作(zuo)用。

我國的建筑垃圾現狀

據(ju)業內人士(shi)估(gu)算，我國每年(nian)(nian)(nian)建(jian)筑(zhu)(zhu)垃圾(ji)產(chan)(chan)(chan)生(sheng)量(liang)可(ke)達(da)(da)20億(yi)噸以(yi)上(shang)，并(bing)且年(nian)(nian)(nian)均(jun)增速(su)可(ke)能保(bao)持10%以(yi)上(shang)。據(ju)住(zhu)建(jian)部公(gong)布(bu)的(de)最新規劃(hua)，到(dao)(dao)2020年(nian)(nian)(nian)中(zhong)國還將新建(jian)住(zhu)宅300億(yi)㎡，產(chan)(chan)(chan)生(sheng)的(de)建(jian)筑(zhu)(zhu)垃圾(ji)至(zhi)少(shao)達(da)(da)到(dao)(dao)50億(yi)t。據(ju)前瞻(zhan)產(chan)(chan)(chan)業研(yan)究院(yuan)《中(zhong)國建(jian)筑(zhu)(zhu)垃圾(ji)處理行業發展前景與(yu)投資分析報(bao)告》保(bao)守(shou)估(gu)計(ji)，未來十年(nian)(nian)(nian)我國平均(jun)每年(nian)(nian)(nian)將產(chan)(chan)(chan)生(sheng)15億(yi)t以(yi)上(shang)的(de)建(jian)筑(zhu)(zhu)垃圾(ji)，預計(ji)2030年(nian)(nian)(nian)建(jian)筑(zhu)(zhu)垃圾(ji)將達(da)(da)到(dao)(dao)73億(yi)t。歐盟國家每年(nian)(nian)(nian)的(de)建(jian)筑(zhu)(zhu)垃圾(ji)資源(yuan)化利(li)用(yong)率達(da)(da)到(dao)(dao)50%，韓(han)國、日本高達(da)(da)97%左(zuo)右(you)，而(er)我國建(jian)筑(zhu)(zhu)垃圾(ji)資源(yuan)化利(li)用(yong)率尚不足10%。……

國家政策下，建筑垃圾資源化利用大勢所趨

建筑垃圾資源化利用好處多多

有(you)研究(jiu)表明，每(mei)利用1億噸(dun)建(jian)筑垃(la)圾(ji)(ji)(ji)可(ke)以生(sheng)產標磚243億塊、混合(he)料(liao)3600萬噸(dun)，減少取(qu)土或(huo)代替天然沙(sha)石1000萬立方米(mi)，節煤270萬噸(dun)，新(xin)增產值84.6億元，創造(zao)巨大(da)經(jing)濟效益。此外(wai)，與簡(jian)單堆放和填埋相(xiang)反(fan)，建(jian)筑垃(la)圾(ji)(ji)(ji)資源化(hua)利用，還(huan)可(ke)減少50%的(de)一氧(yang)化(hua)二氮、99.3%的(de)氮化(hua)物28%的(de)一氧(yang)化(hua)碳排放。據測算，每(mei)1億t建(jian)筑垃(la)圾(ji)(ji)(ji)資源化(hua)利用還(huan)可(ke)以帶來1.5萬個就業崗位。在(zai)骨(gu)料(liao)轉(zhuan)化(hua)率上(shang)，建(jian)筑垃(la)圾(ji)(ji)(ji)可(ke)達85%，即1噸(dun)的(de)建(jian)筑垃(la)圾(ji)(ji)(ji)可(ke)產生(sheng)0.85噸(dun)的(de)再生(sheng)骨(gu)料(liao)、0.01噸(dun)廢鋼，其余為(wei)其他垃(la)圾(ji)(ji)(ji)。再生(sheng)骨(gu)料(liao)的(de)銷售價格約(yue)為(wei)天然砂石材料(liao)售價的(de)60%左右，能夠(gou)有(you)效降低40%以上(shang)的(de)建(jian)筑成(cheng)本，在(zai)成(cheng)本上(shang)占(zhan)有(you)很大(da)優(you)勢。
